1981 Dodge Trucks Tire Fitment Guide

1981 Dodge Trucks vehicles use 15 different tire sizes across seven model families. D150 uses 195/75R15, 215/75R15, 235/70R15, 235/75R15, and LR60-15 on 15-inch wheels; D250 uses 800-16.5, 875-16.5, 8.75R16.5, 950-16.5, and 9.50R16.5 on 16.5-inch wheels; D350 uses 8.00R16.5, 800-16.5, 9.50R16.5, and 950-16.5 on 16.5-inch wheels. D50 uses 6.00-14 and 185R14 on 14-inch wheels, Ramcharger uses 235/75R15, 10R15, and 225/75R15 on 15-inch wheels, W150 uses 235/75R15, 255/70R15, and LR60-15 on 15-inch wheels, and W250 uses 800-16.5, 875-16.5, 8.00R16.5, 9.50R16.5, and 950-16.5 on 16.5-inch wheels.

That spread means there is no one-size answer for 1981 Dodge Trucks as a whole. The quickest way to avoid a wrong turn is to identify the exact model first, then confirm whether the truck has 14-inch, 15-inch, or 16.5-inch wheels before comparing tread style, whitewall treatment, or construction type.

LR60-15 is an alphanumeric radial performance size used on certain 1981 Dodge Trucks D150 and W150 applications. The 15 identifies a 15-inch wheel, the R signals radial construction, and the letter-and-number combination ahead of the dash is the older performance-sizing system rather than a modern metric width and aspect ratio. It belongs to the late-classic era when domestic trucks and sporty cars often used alphanumeric radials for a broader, lower-profile look.

A buyer comparing LR60-15 to a metric size like 235/75R15 should think in terms of style and intended stance as much as simple fitment. If your truck was set up around that alphanumeric format, keeping it there usually preserves the period-correct visual character better than substituting a taller metric radial.

No, 1981 Dodge Trucks models do not share one universal tire size. Some overlap exists, such as 235/75R15 across D150, Ramcharger, and W150, and 800-16.5, 950-16.5, and 9.50R16.5 across several heavy-duty trucks, but many sizes are model-specific. The D50 stands apart with 14-inch fitments, half-ton full-size trucks and the Ramcharger use 15-inch sizes, and the heavier D250, D350, and W250 use 16.5-inch truck sizes.

That matters because a tire that fits one 1981 Dodge truck may be completely wrong for another, even within the same showroom family. A D150 owner and a D350 owner are often shopping in different construction categories, different rim diameters, and different visual styles, so model identification should come before product comparison.

The right choice depends on which 1981 Dodge Trucks model you own and which size family it uses. D50, D250, D350, and W250 applications include both bias-ply and radial formats in parts of their range, while many 15-inch D150, W150, and Ramcharger fitments are radial only. Bias-ply choices keep a more traditional period character, especially on heavy-duty 16.5-inch truck applications, while radial choices generally align better with regular road use and the steering feel most modern drivers expect.

A restoration-minded owner may stay with the original-era construction style, especially for show presentation or a truck that sees lighter use. A driver putting more miles on the truck usually starts by confirming whether a radial version exists in the correct size and wheel diameter, then deciding whether the appearance still suits the truck's intended look.

1981 Dodge Trucks tires span a wide visual range depending on size. Whitewall styles appear in several 14-inch and 15-inch radial sizes, including narrow whitewall and wide whitewall treatments, while blackwall, RBL, RWL, and even redline options appear in certain truck and performance-oriented sizes. The 16.5-inch heavy-duty bias-ply sizes are blackwall-focused, while compact and light-duty road sizes carry the broadest cosmetic variety.

That gives owners room to match the truck's personality rather than treating every 1981 Dodge truck the same way. A compact D50 or a dressed-up D150 can wear whitewalls naturally, a sporty 15-inch application can lean into raised white letters or redlines, and a work-oriented D250 or W250 usually looks most at home with straightforward blackwall truck tires.

Brands covering 1981 Dodge Trucks include Coker Classic, American Classic, BFGoodrich, Tornel, Cooper, Avon, Michelin, Maxxis, STA, Phoenix, and Vredestein. Coverage varies by size: the 15-inch light-duty and SUV sizes have the broadest mix of brands and sidewall treatments, the 14-inch D50 radial size brings in Michelin, Phoenix, and Vredestein, and the 16.5-inch bias-ply truck sizes are carried by STA. That spread reflects how differently Dodge's compact, half-ton, and heavy-duty trucks were used.

Choosing among brands usually comes down to the size your truck requires and the look you want on the sidewall. Once the correct size is established, brand comparison becomes more meaningful because you can weigh appearance, construction style, and product character without crossing into a different fitment category.

Rim width requirements vary by size on 1981 Dodge Trucks. The 195/75R15 fits 5- to 7-inch rims, 215/75R15 fits roughly 5.5- to 7.5-inch rims depending on product, 235/70R15 fits about 6.0- to 8.5-inch rims, 235/75R15 fits about 6.0- to 8.5-inch rims, 800-16.5 fits 6.00- to 6.50-inch rims, 950-16.5 fits 6.50- to 6.75-inch rims, 185R14 fits about 4.0- to 6.5-inch rims, 225/75R15 fits about 6.0- to 8.0-inch rims, and 255/70R15 fits roughly 6.5- to 9.0-inch rims depending on product.

Those ranges are why wheel diameter alone is not enough. Before mounting a reproduction or specialty tire, verify the actual wheel width on the truck and compare it to the range for the exact product you want, especially when moving between stock-looking whitewalls, raised-letter radials, and heavy-duty truck sizes.

Most of the radial passenger and light-truck products shown for 1981 Dodge Trucks are tubeless, and some carry an explicit TL marking in the size stamp, such as 185R14 and 235/70HR15 examples. The 16.5-inch bias-ply truck sizes do not carry a universal tube marker in the available product markings, so tube practice should be matched to the exact tire and wheel combination rather than assumed. That is especially important on older truck wheels that may have seen decades of service or prior repairs.

The safe approach is to inspect the wheel type you actually have and then confirm the sidewall marking on the exact tire before mounting. If the wheel condition, bead area, or valve setup raises questions, a vintage-truck tire specialist or wheel shop can help determine whether a tube, flap, or tubeless installation is appropriate.

Original 1981 Dodge Trucks wheels can only be used with tire sizes that share the same rim diameter and fall within the wheel's width range. A 14-inch D50 wheel cannot take a 15-inch or 16.5-inch tire, and a 15-inch half-ton or Ramcharger wheel cannot accept a 16.5-inch heavy-duty truck tire. Even within one diameter, rim width still matters, especially where sizes such as 195/75R15 and 255/70R15 call for different width ranges.

That means original wheels are often reusable, but only inside the correct size family for the truck you own. Measure the wheel, confirm the stamped or known diameter, and compare its width to the chosen tire's approved range before assuming that any same-era Dodge wheel is automatically compatible.

A stored 1981 Dodge Trucks vehicle should be kept away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that accelerate sidewall aging. Clean, dry concrete is better than damp soil or grass, and maintaining correct inflation helps the tire hold its shape during long periods of inactivity. Bias-ply truck tires are especially prone to temporary flat spotting after sitting, while older radial tires can still suffer from ozone cracking and pressure loss if ignored.

For seasonal or longer-term storage, move the truck periodically or use stands to reduce prolonged loading if the vehicle will sit for months. A tire cover, stable indoor temperature, and a quick pressure check before the truck goes back on the road do more to preserve collector tires than any dressing or cosmetic treatment.

Tires on a 1981 Dodge Trucks vehicle are usually judged more by age than by miles, because many collector and hobby trucks are driven infrequently. A sensible rule is to begin careful evaluation around five to seven years of age and to treat the ten-year point as a strong replacement consideration even if tread remains deep. The DOT date code on the tire tells you when it was made, and that date matters more than how new the truck's restoration may look.

A truck that only appears at shows can still age its tires out before it wears them out. If the vehicle sees highway use, towing, or long-distance travel, replacing older tires before they become visibly deteriorated is usually the wiser move than trying to extract every last season from them.

Tires on a 1981 Dodge Trucks vehicle should be inspected before every drive and again before any extended outing. Look for sidewall cracking, bulges, uneven wear, embedded debris, and signs that the tire has been run underinflated, and make sure it is holding pressure consistently. If the truck uses tube-type hardware or older service wheels, pay close attention to valve stems and any age-related seepage around the rim area.

That quick inspection is especially important on older trucks that may sit for long stretches between uses. Catching a cracked sidewall, a damaged valve stem, or an out-of-round tire in the garage is far easier than dealing with vibration, heat buildup, or a roadside problem once the truck is loaded up and moving.

A 1981 Dodge Trucks D150 could be equipped with several 15-inch sizes, including metric radials such as 195/75R15, 215/75R15, 235/70R15, and 235/75R15, along with the period-style LR60-15 radial. By 1981, radial construction was firmly established across much of the American light-truck market, so a D150 on radial tires is entirely consistent with the era. The exact original size could still vary by trim, package, wheel, and intended use.

If originality matters, start by checking any surviving factory literature, door-jamb tire information, or original-owner paperwork that came with the truck. Marque clubs and Dodge truck specialists are especially helpful when you are trying to pin down whether your specific D150 should wear a more conventional metric radial or a sportier alphanumeric size.

Correct tire fitment absolutely matters when a 1981 Dodge Trucks vehicle is judged for authenticity. Judges and knowledgeable enthusiasts often notice whether the size, construction type, and sidewall treatment fit the period and the personality of the truck, especially on a clean restoration. A wide whitewall where a blackwall truck tire belongs, or a modern-looking substitute in place of a period-correct size format, can stand out even if the wheel diameter is technically right.

That does not mean every show truck needs one exact tire, but it does mean the choice should look intentional and era-appropriate. Before a concours-level restoration is finalized, compare your size and sidewall selection with event rules, factory images, and Dodge truck club guidance so the tire supports the story the truck is trying to tell.

STA Traxion and STA Super Transport both cover certain 16.5-inch bias-ply sizes used on 1981 Dodge Trucks heavy-duty models, but they are not the same tire line. In 800-16.5, Super Transport carries a 2,045-pound load rating at 60 psi and weighs 33 pounds, while Traxion weighs 31 pounds. In 950-16.5, both appear with the same 2,780-pound load rating at 60 psi, while Traxion is 40 pounds and Super Transport is 41 pounds.

For a buyer, that means the decision is not just about size but also about the character of the specific truck tire line within the correct size. If your goal is a heavy-duty restoration or a period-appropriate working-truck look, compare the exact series within your size and wheel application instead of treating every 16.5-inch bias-ply option as interchangeable.

1981 Dodge Trucks tires can be suitable for highway driving when the correct size, load capacity, and construction are matched to the truck and used in sound condition. Several radial sizes carry modern speed ratings, including S to 112 mph, H to 130 mph, and V to 149 mph depending on the tire, while heavy-duty 16.5-inch bias-ply truck tires emphasize load-carrying character more than passenger-car-style speed capability. On many 1981 Dodge trucks, the vehicle's brakes, steering, suspension wear, and overall mechanical condition are at least as important as the tire's upper-speed ceiling.

Highway use should start with realism about how the truck is built and maintained. A well-sorted D150 or Ramcharger on quality radials may feel very different from a one-ton truck on 16.5-inch bias-ply tires, so the safe approach is to choose the right construction for the job and keep speeds consistent with the vehicle's age and condition.

Inflation pressure on 1981 Dodge Trucks tires depends on the exact size and product, not just the truck's year and make. Examples include 195/75R15 products rated at 32 to 35 psi, 215/75R15 products reaching 32, 35, or 50 psi depending on the tire, 235/75R15 products reaching 32, 35, or 50 psi, 185R14 examples at 35 or 51 psi, and heavy-duty 800-16.5 and 950-16.5 truck tires at 60 psi where load data appears. Those are maximum load-and-pressure pairings for specific tires, not a one-pressure rule for every 1981 Dodge truck.

Use the vehicle's original placard or owner's manual as the starting point for factory intent, then compare that with the tire maker's guidance for the exact reproduction or specialty tire you are using. Never transfer the pressure from one size to another simply because both fit the same model family.

Before a longer trip in a 1981 Dodge Trucks vehicle, inspect all tires for cracks, cuts, bulges, punctures, uneven wear, and stable inflation, and do not forget the spare. Check valve stems closely, especially on older wheels and on any truck using tube-type hardware, and make sure the tire size and load rating are appropriate for how the vehicle will be used that day. A long drive also deserves a quick look at wheel lug torque, suspension condition, and brake response.

That pre-drive routine matters because vintage trucks often spend more time parked than driven, and problems can develop quietly between outings. Ten minutes in the garage can reveal an aging sidewall, a leaking stem, or a weak spare before those issues turn a pleasure drive in a classic Dodge truck into a much harder day on the road.
