The 1985 Isuzu Trucks Pickup came from an era when compact pickups were prized for simple utility, light-duty hauling, and everyday drivability, yet trim and drivetrain differences could still change the tire decision. On this truck, fitment centers on two distinct 14-inch tire sizes: a modern-style 195/75R14 radial for Base, DLX 4x2, and LX 4x2 models, and an F70-14 bias-ply fitment for the DLX 4x4 and LX 4x4. That creates a meaningful choice between metric radial practicality and vintage alphanumeric bias-ply character, with additional options in whitewall, redline, pin-white-stripe, and raised white letter styles. The right selection starts with confirming the exact sub-model and then matching the truck's wheels, appearance goals, and intended road use.
Which Tire Size Is Right for The 1985 Isuzu Trucks Pickup
Two primary tire sizes apply to the 1985 Isuzu Trucks Pickup, and both use a 14-inch rim. The correct choice depends on the exact sub-model, because 4x2 trucks use a 195/75R14 radial while 4x4 models use an F70-14 bias-ply size. Before comparing brands or sidewall styles, identify whether the truck is Base, DLX 4x2, DLX 4x4, LX 4x2, or LX 4x4.
195/75R14 is a metric radial size in which 195 is the nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 14 is the wheel diameter in inches. On the 1985 Isuzu Trucks Pickup, this size is used on the Base, DLX 4x2, and LX 4x2 models, making it the modern-style fitment within this range. Available choices include Coker Classic, Tornel, Maxxis, and Travelstar, with wide whitewall and narrow whitewall presentations across several series. It suits owners who want to stay with the truck's radial fitment while comparing appearance, rim-width compatibility, and load specifications carefully.
F70-14 is a vintage alphanumeric bias-ply size in which the letter and series work together to describe the tire's size class and profile family, while 14 identifies the wheel diameter in inches. On the 1985 Isuzu Trucks Pickup, this size applies to the DLX 4x4 and LX 4x4 models and carries a distinctly period-style bias-ply presentation. Firestone and Goodyear options are available in Wide Oval, Custom Wide Tread, and Speedway Wide Tread series with redline, pin-white-stripe, and RWL sidewall treatments. It is the size to evaluate when the truck's original-style 4x4 fitment and vintage appearance matter as much as basic rim diameter.
Sub-model fitment matters on the 1985 Isuzu Trucks Pickup because tire size changes with drivetrain and trim. The 4x2 trucks share one radial size, while the 4x4 models use a different bias-ply size, so identifying the exact version is the first step before comparing tire options.

1985 Isuzu Trucks Pickup Base
The 1985 Isuzu Trucks Pickup Base uses the 195/75R14 radial fitment on a 14-inch rim. That keeps tire selection focused on radial product choice, whitewall style, and wheel-width compatibility rather than deciding between multiple primary sizes.
The 1985 Isuzu Trucks Pickup DLX 4x2 shares the 195/75R14 radial size with the other 4x2 configurations. Tire shopping here is mainly about choosing the right radial style and specifications for the truck's current wheels and intended appearance.
The 1985 Isuzu Trucks Pickup DLX 4x4 uses the F70-14 bias-ply fitment on a 14-inch rim. That makes construction and presentation more important, especially for owners deciding between traditional bias-ply choices and a radial equivalent that should still be checked carefully.
The 1985 Isuzu Trucks Pickup LX 4x2 also uses the 195/75R14 radial size. For this sub-model, the main decision is which radial tire best matches the truck's wheel setup, load needs, and preferred whitewall appearance.
The 1985 Isuzu Trucks Pickup LX 4x4 uses the F70-14 bias-ply size just like the other 4x4 covered here. Selection centers on keeping the vintage alphanumeric fitment or reviewing radial-equivalent alternatives with close attention to wheel width and clearance.
Bias-Ply to Radial Tire Conversion for the 1985 Isuzu Trucks Pickup
For the original F70-14 size, four radial-equivalent options are available. 195R14 is the 80-series metric radial equivalent, P205/75R14 is the P-metric 75-series radial equivalent, P215/70R14 is the P-metric 70-series radial equivalent, and 750R14 is the bias-look radial equivalent. These options differ by sizing format and profile convention, with the bias-look radial intended to retain a more traditional presentation. A 4-6 inch rim-width range is associated with these equivalents, so wheel size, overall dimensions, and vehicle clearance should be checked before conversion.

Tire Size & Fitment
What tire size fits a 1985 Isuzu Trucks Pickup?
A 1985 Isuzu Trucks Pickup uses either 195/75R14 or F70-14, depending on the sub-model. Base, DLX 4x2, and LX 4x2 trucks use 195/75R14 radial tires, while DLX 4x4 and LX 4x4 trucks use F70-14 bias-ply tires.
That means the first step is identifying whether the truck is a 4x2 or 4x4 configuration before choosing a tire. Both sizes fit 14-inch rims, but they differ in sizing system and construction, so wheel width, overall tire dimensions, and clearance should be confirmed before changing size or construction.
What size rim does a 1985 Isuzu Trucks Pickup use?
The tire fitments used on the 1985 Isuzu Trucks Pickup are built around a 14-inch rim diameter. Both the 195/75R14 radial size and the F70-14 bias-ply size are intended for 14-inch wheels, even though the two tires follow different sizing conventions.
Rim diameter is only part of the fitment picture, so it is still important to confirm wheel width before selecting a tire. The available products and equivalents show different rim-width ranges, and that becomes especially important if the truck has replacement wheels or if a 4x4 model is being converted from bias-ply to radial construction.
Do all 1985 Isuzu Trucks Pickup sub-models use the same tire size?
No, the 1985 Isuzu Trucks Pickup does not use one tire size across every sub-model. The Base, DLX 4x2, and LX 4x2 models use 195/75R14 radial tires, while the DLX 4x4 and LX 4x4 models use the F70-14 bias-ply size.
That split matters because a truck's trim and drivetrain determine whether you are shopping a metric radial or a vintage alphanumeric bias-ply fitment. Once the sub-model is confirmed, compare the wheel setup and the intended look of the truck so the selected tire matches both the hardware and the style goals.
Bias-Ply & Radial Options
Is F70-14 a bias-ply or radial tire for the 1985 Isuzu Trucks Pickup?
F70-14 is the bias-ply fitment used on the 1985 Isuzu Trucks Pickup DLX 4x4 and LX 4x4 models. It is a vintage alphanumeric size rather than a modern metric radial size, and the available products in that primary fitment are bias-ply tires.
That construction affects both the truck's period-style appearance and the range of tire choices you will compare. If the goal is to keep the 4x4's original-style tire presentation, staying within the F70-14 bias-ply category makes that easier, while a radial alternative should be reviewed as a separate fitment decision rather than assumed interchangeable.
What radial tire sizes are equivalent to F70-14?
Radial equivalents for F70-14 include 195R14 as an 80-series metric radial, P205/75R14 as a P-metric 75-series radial, P215/70R14 as a P-metric 70-series radial, and 750R14 as a bias-look radial equivalent. Each one offers a different sizing format while remaining part of the F70-14 comparison set.
The practical difference is that these alternatives do not all present the same profile convention or visual character. A 4-6 inch rim-width range is associated with the equivalents, so the wheel itself, plus overall dimensions and available clearance on the truck, should be checked carefully before selecting one of them.
What should I check before converting my 1985 Isuzu Trucks Pickup from bias-ply to radial tires?
Start by confirming that the truck is one of the F70-14 4x4 models and then compare the actual wheel width with the radial equivalent being considered. Radial alternatives exist, but they should be matched to the truck's 14-inch wheels, intended use, and the space available around the suspension and fenders.
Construction changes can also affect the overall feel and appearance of a restoration-minded truck, so the decision is not only about size. It helps to inspect wheel condition, measure clearance at full steering lock, and make sure the chosen radial's dimensions and load capacity suit the vehicle before making the switch.
Choosing the Right Tire
What should I consider when choosing a tire for a 1985 Isuzu Trucks Pickup?
Begin with the exact sub-model, because a 1985 Isuzu Trucks Pickup may need either a 195/75R14 radial or an F70-14 bias-ply tire. From there, compare construction, wheel compatibility, sidewall presentation, and the truck's intended use rather than focusing on size alone.
A 4x2 truck usually centers the decision on which radial product and whitewall treatment fit the desired look, while a 4x4 brings in the question of traditional bias-ply appearance versus radial-equivalent alternatives. Checking rim width, load figures, and the condition of the existing wheels helps narrow the best match for the truck's setup.
What sidewall styles are available for 1985 Isuzu Trucks Pickup tires?
The available sidewall styles vary by tire size. In 195/75R14, the choices include wide whitewall and narrow whitewall radial tires, while F70-14 bias-ply options include redline, pin-white-stripe, and RWL sidewall treatments.
That gives the truck owner two very different appearance paths depending on sub-model and tire construction. A whitewall radial can suit a more traditional street presentation on a 4x2, while redline, pin-white-stripe, or raised white letter bias-ply tires create a stronger vintage look on an F70-14-equipped 4x4.
What brands offer tires for the 1985 Isuzu Trucks Pickup?
Tires for the 1985 Isuzu Trucks Pickup are available from several brands depending on size. The 195/75R14 radial fitment includes Coker Classic, Tornel, Maxxis, and Travelstar, while the F70-14 bias-ply fitment is available from Firestone and Goodyear.
Brand comparison is most useful after the correct size and construction are settled. Once that is done, look at differences in tire series, sidewall style, load figures at stated pressures, product weight, and rim-width specification so the final choice matches both the truck's hardware and the appearance you want.
Restoration & Appearance
Which tire should I choose for a period-style 1985 Isuzu Trucks Pickup?
A period-style choice starts with using the correct primary size for the truck's sub-model. That means 195/75R14 radial for the Base, DLX 4x2, and LX 4x2, or F70-14 bias-ply for the DLX 4x4 and LX 4x4 models, then selecting a sidewall treatment that suits the truck's presentation.
For many owners, the bias-ply F70-14 route carries the strongest vintage character, while a radial fitment can still support a traditional look through whitewall styling. When exact originality matters beyond general period style, marque references and vehicle-specific historical material remain the best way to verify appearance details.
How does tire construction affect the appearance of a restored 1985 Isuzu Trucks Pickup?
Tire construction changes the visual character of a restored 1985 Isuzu Trucks Pickup because radial and bias-ply tires present the vehicle differently. On this truck, 195/75R14 is the radial fitment used on the 4x2 models, while F70-14 is the bias-ply fitment used on the 4x4 models.
That difference becomes more noticeable when sidewall style is part of the build theme. Wide or narrow whitewalls create one kind of traditional look, while redline, pin-white-stripe, and raised white letter bias-ply tires create another, so construction should be chosen with the truck's restoration direction in mind instead of as a purely cosmetic afterthought.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1985 Isuzu Trucks Pickup?
Yes, modifications can affect tire fitment on a 1985 Isuzu Trucks Pickup even when the tire size itself is correct. Changes to wheel width, wheel offset, suspension height, or steering components can alter how a 195/75R14 or F70-14 tire sits and clears the truck.
That is especially important on older pickups that may have replacement wheels or altered ride height after years of use. Measuring the current wheel setup and checking clearance at the fenders, frame, and steering range helps prevent choosing a tire that matches the catalog size but conflicts with the truck's actual configuration.
What should I inspect before driving a 1985 Isuzu Trucks Pickup on new tires?
Before road use, inspect the wheels for damage or excessive corrosion, verify tire pressure, and confirm that each tire matches the truck's correct size and rim diameter. It also helps to look over suspension and steering components so the new tires are not being asked to compensate for unrelated mechanical issues.
A short recheck after initial driving is worthwhile on a collector-era pickup. Pay attention to air loss, uneven wear, rubbing, vibration, and any contact at full steering lock, because those signs can reveal wheel-width mismatch, alignment problems, or clearance issues that were not obvious when the truck was standing still.
How should tires on a collector 1985 Isuzu Trucks Pickup be maintained?
Collector-use tires on a 1985 Isuzu Trucks Pickup should be maintained with regular pressure checks, visual inspections, and clean storage conditions. Older trucks often spend long periods parked, so tread depth alone is not enough; sidewall cracking, bulges, cuts, and signs of air loss deserve equal attention.
Storage habits matter just as much as mileage on a vehicle like this. Keeping the truck away from prolonged sunlight, moisture, and ozone sources can help preserve tire condition, and moving or driving it occasionally helps avoid long-term flat spotting while giving you a chance to catch clearance or wear issues early.
