The 1989 Nissan Trucks range covered two closely related but distinctly positioned utility vehicles: the compact D21 pickup and the Pathfinder sport utility. By that point Nissan had fully moved into modern radial sizing, but the tire story still varies across the lineup because wheel diameter and overall tire footprint changed with trim, stance, and intended use. Across these two models, five tire sizes appear, with some shared between both the D21 and Pathfinder and others reserved to the D21 alone. For 1989 Nissan Trucks, the first thing to confirm is whether you have a D21 or a Pathfinder, then whether your truck uses a 14-inch or 15-inch wheel.
Which Tire Size Is Right for Your 1989 Nissan Trucks
Five tire sizes are used across 1989 Nissan Trucks vehicles, and they vary by model rather than carrying across the full range. The real decision starts with confirming whether your truck uses a 14-inch or 15-inch wheel, then narrowing down the correct radial size for your D21 or Pathfinder. Understanding that distinction before choosing a product saves time and helps match the tire to the right vehicle setup.
Year(s): 1989|Fit(s): D21|Construction: Radial|Rim: 14 in
195/75R14 is a metric radial size with a 195-millimeter section width, a 75-series aspect ratio, and a 14-inch rim diameter. This D21-specific size is available from Coker Classic, Tornel, and Maxxis in wide whitewall and narrow whitewall styles, with load capacities reaching 1,521 pounds at 32 psi and 1,433 pounds at 35 psi. It suits a D21 owner who needs the smaller 14-inch wheel fitment and wants a light-truck-era radial in a more classic-looking sidewall treatment.
Year(s): 1989|Fit(s): D21, Pathfinder|Construction: Radial|Rim: 15 in
215/75R15 is a metric radial size with a 215-millimeter section width, a 75-series aspect ratio, and a 15-inch rim diameter. It is shared by both the D21 and Pathfinder, and it is available from BFGoodrich, Coker Classic, and Tornel with RBL, narrow whitewall, and wide whitewall sidewalls; speed rating varies by product, with BFGoodrich carrying an S rating up to 112 mph. This size makes sense for owners who need a 15-inch fitment but want a moderate-width radial, whether the goal is a truck-style black sidewall look or a more custom whitewall presentation.
Year(s): 1989|Fit(s): D21|Construction: Radial|Rim: 14 in
215/75R14 is a metric radial size with a 215-millimeter section width, a 75-series aspect ratio, and a 14-inch rim diameter. This size is specific to the D21 and comes from Coker Classic and American Classic in wide whitewall and narrow whitewall styles, with load capacities ranging from 1,664 pounds at 35 psi to 1,764 pounds at 32 psi. It is the broader of the two 14-inch D21 sizes and fits buyers who want a fuller stance on a 14-inch wheel without moving to the truck's 15-inch applications.
Year(s): 1989|Fit(s): D21, Pathfinder|Construction: Radial|Rim: 15 in
235/75R15 is a metric radial size with a 235-millimeter section width, a 75-series aspect ratio, and a 15-inch rim diameter. Shared by the D21 and Pathfinder, it is available from BFGoodrich, American Classic, Maxxis, and Coker Classic with RWL, narrow whitewall, and wide whitewall sidewalls; BFGoodrich carries an S rating up to 112 mph, while the whitewall offerings focus on classic radial styling. This is a strong choice for owners who want a wider 15-inch fitment, either in an all-terrain visual style or in a period-flavored whitewall radial.
Year(s): 1989|Fit(s): D21, Pathfinder|Construction: Radial|Rim: 15 in
31X10.50R15 is a flotation-style radial size that indicates an approximate 31-inch overall diameter, a 10.50-inch section width, and a 15-inch rim diameter. It is shared by the D21 and Pathfinder and appears here as a BFGoodrich RWL all-terrain radial with an S speed rating up to 112 mph and a load capacity of 2,270 pounds at 50 psi. This size is the most truck-oriented option in the 1989 Nissan Trucks range and best suits owners seeking the taller, wider footprint associated with off-road and 4x4-oriented use.
Two 1989 Nissan Trucks models are covered here: the D21 pickup and the Pathfinder SUV. They do not all use the same tire size, so identifying the model matters before choosing a tire, especially because the D21 spans both 14-inch and 15-inch wheel fitments while the Pathfinder stays with 15-inch applications. Select your model below to narrow the fitment history and see the sizes that apply to your truck.
1989 Nissan Trucks D21
The D21 was Nissan's compact pickup of the late 1980s, valued for its straightforward packaging, durable work-truck character, and broad mix of two-wheel-drive and four-wheel-drive configurations. Its tire range is the widest in the 1989 Nissan Trucks family, covering both 14-inch and 15-inch wheel applications depending on how the truck was equipped.
The Pathfinder gave Nissan a more family- and recreation-oriented utility vehicle while retaining the rugged, body-on-frame feel buyers expected from a truck-based SUV in this era. Every Pathfinder tire application here mounts on a 15-inch wheel, with sizing that ranges from moderate street-oriented fitments to a taller 31-inch truck size.
Twenty-four products are available across five tire sizes for 1989 Nissan Trucks vehicles. 195/75R14 spans 4 radial products from Coker Classic, Tornel, and Maxxis in narrow and wide whitewall styles; 215/75R15 spans 4 from BFGoodrich, Coker Classic, and Tornel in RBL, narrow, and wide whitewall; 215/75R14 spans 4 from Coker Classic and American Classic in narrow and wide whitewall; 235/75R15 spans 4 from BFGoodrich, American Classic, Maxxis, and Coker Classic in RWL, narrow, and wide whitewall; 31X10.50R15 carries 1 BFGoodrich radial in RWL. Confirm your model, wheel diameter, and preferred sidewall style before selecting.

These answers focus on how 1989 Nissan Trucks tire sizing changes between the D21 and Pathfinder, how the 14-inch and 15-inch applications differ, and what sidewall, rim-width, and long-term collector-use details matter before choosing a tire.
Size Basics & Fitment
What tire sizes fit 1989 Nissan Trucks vehicles?
1989 Nissan Trucks vehicles use five sizes across the D21 and Pathfinder: 195/75R14, 215/75R14, 215/75R15, 235/75R15, and 31X10.50R15. The D21 uses all five depending on configuration, while the Pathfinder uses 215/75R15, 235/75R15, and 31X10.50R15. The 14-inch sizes mount on 14-inch wheels, and the other three mount on 15-inch wheels. Rim-width ranges where available run from 5.00-7.00 inches for 195/75R14, 5.50-7.50 inches for 215/75R14, 5.5-7.5 inches for 215/75R15, 6.00-8.50 inches for 235/75R15, and 7.0-9.0 inches for 31X10.50R15.
That means year and make alone are not enough for a correct choice on 1989 Nissan Trucks. Start by confirming whether you have a D21 or Pathfinder, then verify the wheel diameter actually on the truck before moving to tread style or sidewall appearance. A truck wearing 14-inch wheels immediately narrows the search to D21-only sizes, while a 15-inch truck could still use several different widths and overall diameters.
What does 195/75R14 mean on a 1989 Nissan Trucks tire?
On a 1989 Nissan Trucks tire, 195/75R14 is a modern metric radial size. The 195 is the nominal section width in millimeters, 75 is the aspect ratio, the R means radial construction, and 14 is the wheel diameter in inches. Within the 1989 Nissan Trucks range, that size is used on the D21 rather than the Pathfinder and appears with classic whitewall treatments from brands such as Coker Classic, Tornel, and Maxxis.
For a buyer, the important point is that 195/75R14 is both a size and a wheel-diameter commitment. If your D21 currently has 15-inch wheels, this is not the right place to start, even if the truck looks otherwise similar to another 1989 Nissan pickup. Once the 14-inch wheel is confirmed, the real choice becomes sidewall appearance and how closely you want the truck to lean toward stock-style road use or a more custom visual presentation.
Do all 1989 Nissan Trucks models use the same tire size?
No, 1989 Nissan Trucks models do not all use the same tire size. The D21 spans both 14-inch and 15-inch applications and can use 195/75R14, 215/75R14, 215/75R15, 235/75R15, or 31X10.50R15. The Pathfinder stays with 15-inch fitments and uses 215/75R15, 235/75R15, or 31X10.50R15. Some sizes overlap between the two models, but the D21 has its own 14-inch applications that the Pathfinder does not share.
That difference matters most when a truck has had wheels changed over the years, which is common with late-1980s compact pickups and SUVs. If you are unsure what your truck left the factory with, inspect the tire sidewall already on the vehicle and confirm the wheel diameter before ordering. Model identification gets you close, but the actual wheel on the truck is what decides whether you need a 14-inch or 15-inch tire.
Buying the Right Tire
What sidewall styles are available for 1989 Nissan Trucks tires?
1989 Nissan Trucks tires cover a wider sidewall range than many buyers expect. The 14-inch sizes are available in narrow whitewall and wide whitewall form, 215/75R15 adds RBL alongside narrow and wide whitewall options, 235/75R15 adds RWL alongside whitewall styles, and 31X10.50R15 appears as an RWL all-terrain tire. That gives the 1989 Nissan Trucks lineup everything from subdued black-sidewall truck looks to distinctly custom or period-flavored whitewall appearances.
Choosing among those styles depends less on fitment than on how you want the truck or SUV to present. A whitewall can suit a custom street build, mini-truck aesthetic, or a more stylized restoration, while RBL and RWL all-terrain styles feel more at home on utility-focused D21 and Pathfinder builds. Sidewall style is one of the easiest ways to change the character of a 1989 Nissan Trucks vehicle without changing the basic size.
What brands make tires for 1989 Nissan Trucks vehicles?
1989 Nissan Trucks tire coverage comes from BFGoodrich, Coker Classic, Tornel, Maxxis, and American Classic. The 195/75R14 size appears from Coker Classic, Tornel, and Maxxis; 215/75R14 from Coker Classic and American Classic; 215/75R15 from BFGoodrich, Coker Classic, and Tornel; 235/75R15 from BFGoodrich, American Classic, Maxxis, and Coker Classic; and 31X10.50R15 from BFGoodrich. All of the sizes in this range use radial construction.
That mix gives 1989 Nissan Trucks owners a choice between truck-oriented all-terrain names and classic-style radial lines with whitewall emphasis. If your priority is a more utility-driven appearance, BFGoodrich tends to define the black-sidewall and raised-letter end of the range. If your truck is being styled for a more custom street look, the whitewall-focused offerings from Coker Classic, American Classic, Tornel, and Maxxis open up more visual options.
What is the difference between 235/75R15 and 31X10.50R15 for 1989 Nissan Trucks?
For 1989 Nissan Trucks, 235/75R15 is a metric radial that fits a 15-inch wheel and appears in several styles, including RWL, narrow whitewall, and wide whitewall, with rim-width ranges reaching 6.00-8.50 inches and load capacities up to 2,271 pounds at 32 psi. The 31X10.50R15 is a taller flotation-style radial on the same 15-inch wheel diameter, using a wider 7.0-9.0 inch rim range and carrying 2,270 pounds at 50 psi in the BFGoodrich all-terrain form shown here.
The practical difference is overall stance and intended visual character. A 235/75R15 keeps you in a conventional metric truck size with more sidewall-style variety, while a 31X10.50R15 moves toward a taller, more assertive 4x4 look. Because both mount on 15-inch wheels, the decision is less about wheel diameter and more about whether your truck or Pathfinder is set up for the added height and width of the 31-inch tire.
Fitting & Setup
What rim width do 1989 Nissan Trucks tires require?
Rim-width guidance for 1989 Nissan Trucks varies by size. The 195/75R14 products span 5.00-7.00 inches, while 215/75R14 runs from 5.5-7.5 inches. On the 15-inch side, 215/75R15 ranges from 5.5-7.5 inches, 235/75R15 ranges from 6.0-8.5 inches, and 31X10.50R15 uses 7.0-9.0 inches. Those ranges matter because the same wheel diameter does not guarantee the same approved wheel width.
Use those ranges as a wheel check before settling on a wider or taller size. A truck that can physically accept a 15-inch tire may still have a wheel too narrow or too wide for the size you want to run. If the wheel has already been changed from original, measure the wheel width directly or verify its specification before committing to a different 1989 Nissan Trucks tire size.
Do 1989 Nissan Trucks tires require inner tubes?
The 1989 Nissan Trucks sizes here are modern radial applications, and the available products are presented without tube-type markings. Sizes such as P195/75R14, P215/75R14, 215/75R15 100S, 235/75R15 104S, and 31X10.5R15 109S follow the normal tubeless radial pattern used on late-1980s trucks and SUVs. That aligns with what most buyers would expect for D21 and Pathfinder wheel and tire combinations from this era.
Even so, confirm the tire's sidewall marking and the condition of the wheel before installation, especially if the truck has aftermarket wheels or older steel wheels with rust, pitting, or damage at the bead seat. Tube decisions should follow the specific tire and wheel combination rather than habit. On a 1989 Nissan Trucks vehicle, wheel condition often matters just as much as tire design when you want reliable air retention.
Can the original 1989 Nissan Trucks wheels be used with both or all tire sizes?
Original 1989 Nissan Trucks wheels cannot be treated as universal across all five sizes because the lineup spans both 14-inch and 15-inch rim diameters. A D21 on 14-inch wheels is limited to 195/75R14 or 215/75R14, while 215/75R15, 235/75R15, and 31X10.50R15 all require a 15-inch wheel. Even within the 15-inch group, approved rim-width ranges change as the tire gets wider and taller.
That means wheel diameter is your first checkpoint and wheel width is the second. If your truck still wears its original wheels, match the tire size to that wheel before thinking about appearance or load capacity. If you are working with a Pathfinder or a D21 that has already been upgraded to 15-inch wheels, you may have several tire choices, but the wheel still needs to fall inside the correct width range for the size you want.
Maintenance, Storage & Longevity
How should I store a 1989 Nissan Trucks when the tires are fitted?
A stored 1989 Nissan Trucks vehicle should be kept out of direct sunlight and away from ozone-producing equipment such as electric motors, compressors, and battery chargers. Clean, dry concrete is better than damp ground, and maintaining proper inflation helps the carcass hold its shape during storage. Because these are radial tires, they generally tolerate stationary periods better than older bias-ply designs, but they still benefit from occasional movement to avoid long-term flat spotting.
If the truck will sit for months, roll it periodically or place it on stands that reduce constant load without letting the suspension hang in an unsafe way. That is especially helpful on heavier Pathfinder and 4x4-style setups using 235/75R15 or 31X10.50R15. Good storage habits preserve sidewalls, slow cracking, and make the truck more pleasant to return to when driving season starts again.
How long do tires on a 1989 Nissan Trucks typically last?
Tires on a 1989 Nissan Trucks vehicle should be judged more by age and condition than by mileage alone. A good rule is to start evaluating them closely once they reach about five to seven years of age and to treat ten years as a serious replacement point even if tread remains. The DOT date code on the tire sidewall identifies when the tire was built, and that date matters on collector-driven trucks that may cover only modest annual mileage.
Low use can make old tires look better than they really are, especially on a truck that spends much of its life garaged. Sidewall cracking, hardened rubber, vibration, and poor wet-road behavior can all show up before the tread is gone. If a 1989 Nissan Trucks vehicle still wears tires of uncertain age, checking the date code is one of the smartest first steps before planning regular driving or longer highway trips.
How often should tires on a 1989 Nissan Trucks be inspected?
Tires on a 1989 Nissan Trucks vehicle deserve a quick inspection before every drive and a more deliberate check before any longer outing. Look for sidewall cracks, weathering, cuts, bulges, irregular wear, and any sign that a tire is losing pressure between uses. On trucks that are driven infrequently, pressure loss can go unnoticed for weeks, and that is often when sidewall damage begins from operating a tire underinflated.
A longer inspection should also include the spare, valve stems, and the wheel itself for rust or bead-seat issues. Owners running larger 15-inch truck sizes should pay attention to tread wear patterns that can point to alignment or suspension problems. Catching those issues early helps preserve the tires and makes a 1989 Nissan Trucks vehicle feel more settled and predictable when it is time to get back on the road.
Restoration & Authenticity
What tires were originally fitted to the 1989 Nissan Trucks D21?
The 1989 Nissan Trucks D21 belongs to an era when radial tires were already the standard choice for mainstream pickups, and every size associated with the D21 here is a radial. Depending on configuration, the D21 used 14-inch or 15-inch tire fitments, including 195/75R14, 215/75R14, 215/75R15, 235/75R15, and 31X10.50R15. That means originality starts with matching the truck's actual wheel diameter and factory-style size range rather than assuming every D21 used the same tire.
For restoration work, the safest path is to verify the original size from the truck's door-jamb label, owner's literature, or a Nissan truck specialist familiar with your exact configuration. Sidewall style is a separate judgment call, especially on a truck that may be restored stock, built as a period mini-truck, or preserved as a utility 4x4. Marque clubs and original sales material are the best tie-breakers when two plausible sizes could both fit the same 1989 Nissan Trucks D21.
Does correct tire fitment matter for showing a 1989 Nissan Trucks?
Correct tire fitment does matter when a 1989 Nissan Trucks vehicle is being judged for originality or period presentation. Judges and knowledgeable enthusiasts notice whether the truck wears the right general size family, the proper wheel diameter, and a sidewall style that fits the way the vehicle is restored. On a late-1980s Nissan pickup or Pathfinder, a mismatch between a stock-style truck build and an obviously custom whitewall or oversized 31-inch tire can change the vehicle's visual credibility quickly.
The standard depends on the event. A survivor-style D21 work truck, a showroom-style Pathfinder, and a period custom mini-truck may all call for different visual cues even when the tire technically fits. If you plan to show a 1989 Nissan Trucks vehicle seriously, confirm what the event rewards before choosing between black sidewalls, raised-letter truck tires, or whitewall radials.
What is the difference between Coker Classic and American Classic in 215/75R14 for the 1989 Nissan Trucks?
In 215/75R14 for the 1989 Nissan Trucks D21, Coker Classic appears in both wide whitewall and narrow whitewall forms, while American Classic appears here as a narrow whitewall radial. Coker Classic products in this size carry load figures up to 1,764 pounds at 32 psi and 1,664 pounds at 35 psi, with rim-width coverage from 5.5 to 7.5 inches. The American Classic version carries 1,664 pounds at 35 psi and also fits a 5.50-7.50 inch rim range.
The real distinction is visual presentation more than basic fitment. If your 1989 Nissan Trucks D21 build wants a broader whitewall statement, Coker Classic opens that door, while both brands cover the narrower whitewall look. On a restoration or style-driven truck, those sidewall proportions can matter just as much as the size itself, so compare the tire's appearance to the era and theme you want the finished D21 to project.
Safety & Road Use
Are 1989 Nissan Trucks tires safe for highway driving?
1989 Nissan Trucks tires in these sizes are modern radial designs, which is a good foundation for regular road use when the tires are fresh, correctly inflated, and matched to the proper wheel. Where speed ratings appear, BFGoodrich 215/75R15, 235/75R15, and 31X10.50R15 products carry an S rating, which corresponds to 112 mph. In normal use, that ceiling is well beyond the speed most late-1980s D21 and Pathfinder trucks should ever see, and the vehicle's age, suspension condition, brakes, and loading matter at least as much as the tire itself.
Highway safety comes down to condition and setup more than marketing category. An older truck with worn shocks, loose steering parts, or aged bushings can feel unstable even on excellent tires. Before treating a 1989 Nissan Trucks vehicle as road-trip ready, make sure the tires are recent enough, pressure is correct, and the rest of the chassis is in equally sound condition.
What inflation pressure should I use for 1989 Nissan Trucks tires?
Inflation pressure on 1989 Nissan Trucks tires should start with the vehicle manufacturer's recommendation for the truck and size you are actually running, then be checked against the tire's own maximum load-and-pressure marking. In these sizes, examples include 1,521 pounds at 32 psi for one 195/75R14, 1,764 pounds at 32 psi and 1,664 pounds at 35 psi for 215/75R14 products, 1,765 pounds at 50 psi for one 215/75R15, 2,271 pounds at 32 psi and 1,985 pounds at 50 psi among 235/75R15 products, and 2,270 pounds at 50 psi for 31X10.50R15.
Those figures are load limits at maximum stated pressure, not a universal instruction to inflate every tire to the highest number on the sidewall. A lightly loaded D21 street truck and a taller 4x4-style Pathfinder may need very different real-world pressures within the safe operating range. Use the owner's manual or door-jamb guidance as your baseline, then fine-tune only within the tire maker's approved limits.
What should I check before taking a 1989 Nissan Trucks on a longer drive?
Before a longer drive in a 1989 Nissan Trucks vehicle, inspect each tire for cracking, punctures, sidewall bulges, uneven wear, and signs of age-related hardening. Confirm cold pressure, check the spare, and look over the valve stems for weathering or leaks. On larger truck sizes such as 235/75R15 and 31X10.50R15, make sure the tires clear properly and that the steering and suspension feel settled with no rubbing, wandering, or vibration.
The tires are only one part of the trip-prep picture on a 1989 Nissan Trucks vehicle. Brake condition, wheel bearing health, alignment, shocks, and cooling-system reliability all matter on an older pickup or SUV that may have spent long periods in storage. A careful pre-drive inspection reduces the chance that a small, visible tire issue becomes the reason the trip ends on the shoulder.
