1991 Plymouth Tire Fitment Guide

1991 Plymouth vehicles use eight radial sizes across four model lines: 185/70R14, 195/70R14, 205/60R15, 155/80R13, 175/70R13, 165/80R13, 185/70R13, and 205/55R16. The Acclaim uses 185/70R14, 195/70R14, and 205/60R15; the Colt uses 155/80R13, 165/80R13, 175/70R13, 185/70R13, and 185/70R14; the Laser uses 185/70R14 and 205/55R16; and the Sundance uses 185/70R14. Rim diameters span 13, 14, 15, and 16 inches, and published rim-width ranges include 4.00 to 5.50 inches on some 13-inch sizes, 4.5 to 6.5 inches on several 14-inch sizes, 5.5 to 7.5 inches on 15-inch sizes, and 5.5 to 7.5 inches on 16-inch sizes.

That spread means year and make alone are not enough to choose a tire for a 1991 Plymouth. Start by identifying the exact model, then confirm the wheel diameter already on the car before comparing brands, sidewall styling, or speed ratings. That is especially important on Acclaim, Colt, and Laser applications, where multiple sizes exist within the same model line.

On a 1991 Plymouth tire, 185/70R14 is a metric radial size code. The 185 is the nominal section width in millimeters, 70 is the aspect ratio, meaning the sidewall height is 70 percent of the section width, R means radial construction, and 14 is the wheel diameter in inches. This size appears across the broadest range of 1991 Plymouth models here, including Acclaim, Colt, Laser, and Sundance.

Because 185/70R14 was used so widely across the 1991 Plymouth range, it is a good example of why the code itself matters more than the model badge alone once wheel diameter is confirmed. It also carries the broadest styling spread, including blackwall and wide whitewall choices, so owners can lean more toward factory-style appearance or a more personalized vintage look without changing the basic fitment.

No. While 185/70R14 appears on all four 1991 Plymouth model cores covered here, the lineup does not share one universal tire size. Acclaim also uses 195/70R14 and 205/60R15, Colt adds four more sizes in 13- and 14-inch form, and Laser also uses a larger 205/55R16 fitment. Sundance is the simplest case, using only 185/70R14 in this group.

That overlap can be misleading, especially if a car has had wheels changed over the years. A 1991 Plymouth owner should treat the common 185/70R14 as one possible fitment, not an automatic answer. Checking the exact model and current wheel size first prevents ordering a tire that matches another Plymouth from the same year but not the car actually being restored or driven.

1991 Plymouth tire choices span several sidewall styles depending on size. Blackwall options appear in 175/70R13, 185/70R14, 195/70R14, 205/55R16, and 205/60R15. Wide whitewall choices appear in 155/80R13, 165/80R13, 185/70R13, 185/70R14, and 205/60R15, while narrow whitewall appears in 155/80R13 and RWL appears in 205/60R15. Redline is also available in 185/70R13.

For a 1991 Plymouth, sidewall style is usually an appearance decision after size is settled. A blackwall often suits a stock late-1980s to early-1990s look, especially on sporty applications like the Laser, while whitewalls and redlines can push the car toward a custom, nostalgic, or show-oriented presentation. Matching the sidewall style to the era and personality of the specific model usually matters more than trying to force one look across the entire Plymouth range.

1991 Plymouth vehicles are covered by Avon, American Classic, BFGoodrich, Coker Classic, Dunlop, Maxxis, Michelin, Tornel, and Travelstar depending on size. The common 185/70R14 size is available from BFGoodrich, Avon, Dunlop, and Michelin. The 205/60R15 Acclaim size comes from Michelin, American Classic, Coker Classic, and BFGoodrich, while Colt's 13-inch sizes draw from mixes of Travelstar, BFGoodrich, Maxxis, Tornel, Avon, and Dunlop. Laser's 205/55R16 size comes from BFGoodrich and Michelin.

Brand choice on a 1991 Plymouth usually comes down to the balance between appearance and intended use after the correct size is confirmed. Some sizes lean heavily toward classic-style whitewall offerings, while others skew toward blackwall performance radials. It is often smartest to narrow the decision by wheel diameter and sidewall preference first, then compare the brand options available in that exact size rather than starting with a favorite brand and trying to make it fit.

On overlapping 1991 Plymouth sizes such as 185/70R14 and 185/70R13, BFGoodrich Silvertown Radial and Avon CR6ZZ serve different visual and use-case roles. Silvertown Radial versions in those sizes appear in whitewall or redline styles and carry published rim-width ranges such as 5.00 to 6.50 inches on 185/70R13 and 185/70R14. Avon CR6ZZ versions in 185/70R13 and 185/70R14 are blackwall radials with H speed ratings, a 130 mph ceiling, and rim-width ranges of 4.5 to 6.0 inches.

For a 1991 Plymouth owner, that means the real difference is not simply brand name but the kind of car you are trying to present. Silvertown Radial fits more naturally when period-flavored styling is part of the goal, while CR6ZZ suits owners who want a blackwall appearance and a clearly marked modern speed category. Wheel width should still be checked against the tire you choose, because the acceptable rim range is not identical between the two.

Rim-width ranges on 1991 Plymouth tires vary by size and sometimes by brand within the same size. Examples include 155/80R13 at 4.00 to 5.50 inches, 165/80R13 at 4.50 to 6.00 inches, 175/70R13 at 4.5 to 6.0 inches, 185/70R13 at 4.5 to 6.5 inches depending on the tire, 185/70R14 at 4.5 to 6.5 inches depending on the tire, 205/60R15 at 5.5 to 7.5 inches, and 205/55R16 at 5.5 to 7.5 inches.

That matters because two tires with the same nominal size can still have slightly different approved wheel ranges. If your 1991 Plymouth still wears original wheels, measure or verify the wheel width before settling on a specific product. If the car has aftermarket wheels, rim width becomes even more important, since an incorrect wheel width can affect appearance, section shape, and the way the tire seats and behaves.

Most 1991 Plymouth tire offerings here are radial passenger-car tires, and some carry explicit tubeless markings such as Michelin XAS in 185/70R14, Michelin Primacy 3 in 205/60R15, and Michelin SX MXX3 N2 in 205/55R16. Many other products do not spell out tube status in the size marking, so tube use can vary by product rather than being assumed across the whole size. None of these fitments are antique tube-type dimensions in the traditional prewar sense.

The practical step is to verify the exact sidewall marking on the tire you intend to run and make sure it matches the wheel condition and wheel design on your 1991 Plymouth. A tubeless-marked tire still depends on a sound wheel and valve setup, while any application using tubes should also include a close look at valve stems, flap needs where applicable, and heat or chafing issues from old hardware.

A 1991 Plymouth should be stored in a cool, dry, dark place away from direct sunlight, electric motors, welders, furnaces, and other ozone-producing equipment. Keep the tires clean, maintain inflation, and avoid letting the car sit on damp ground for extended periods. Radials generally tolerate storage better than old bias-ply designs, but flat-spotting, sidewall aging, and ozone exposure still matter on any collector-driven Plymouth.

For seasonal storage, moving the car periodically or placing it on stands can reduce long-term stress on the carcass, especially if the car sits for months at a time. If your 1991 Plymouth is driven only occasionally, storage habits may affect tire condition more than mileage. A car that looks fine cosmetically can still develop age-related issues if the tires spend years parked in one position near heat and ozone sources.

Tires on a 1991 Plymouth are usually judged by age and condition more than by mileage, especially on collector or low-use cars. A sensible rule is to begin evaluating them closely around five to seven years of age and to treat roughly ten years as a strong replacement consideration regardless of tread depth. The DOT date code on the sidewall is the starting point for that timeline, even if the car is driven only occasionally.

A 1991 Plymouth that sees weekend use can wear very little tread while still aging out from time, heat cycles, and storage conditions. Cracks, hardening rubber, vibration, or persistent air loss are often more meaningful than remaining tread depth alone. Owners who do not know the age of their tires should inspect the date code before planning longer drives or deciding whether an otherwise attractive older tire is still worth using.

Tires on a 1991 Plymouth should be checked before every drive and given a more careful inspection before any extended highway outing. Look for sidewall cracking, tread separation, cuts, bulges, uneven wear, and signs of air loss. Pressure should be verified with a gauge rather than guessed visually, and any setup using tubes or older valve hardware deserves extra attention around the valve stem and bead area.

Frequent inspection is especially worthwhile on a low-mileage Plymouth because age-related issues can develop without much visible tread wear. A short local trip may hide a problem that becomes serious at sustained speed or highway temperature. Making tire inspection part of the car's standard pre-drive routine helps catch age, storage, and inflation issues before they turn into a roadside problem.

A 1991 Plymouth Acclaim would have been equipped from the factory with radial tires, not bias-ply construction, and the fitments here are 185/70R14, 195/70R14, and 205/60R15 depending on the specific application. That matches the period, when mainstream American front-wheel-drive sedans had fully transitioned to metric radial sizing. Original-equipment branding could vary by assembly source, trim, and market, so size and construction are the most important authenticity points to confirm first.

For restoration accuracy, an Acclaim owner should focus on matching the exact size shown on the car's original tire placard, manual, or surviving factory label rather than choosing by appearance alone. Sidewall treatment matters too, since a blackwall look is generally closer to mainstream early-1990s family-sedan practice than a broad whitewall treatment. For show-level judging, marque clubs and original literature are the best way to confirm market-specific details.

Correct tire fitment does matter when a 1991 Plymouth is judged seriously, even though these cars sit in a newer part of the collector market than mid-century classics. Judges and knowledgeable enthusiasts often notice the overall combination of size, sidewall style, and wheel diameter first. A 13-inch Colt tire on a 14-inch application, a 16-inch Laser tire on the wrong wheel, or an obviously custom sidewall treatment can change the car's visual authenticity quickly.

For most 1991 Plymouth show cars, the safest path is to match the exact size and wheel diameter used on that model and then choose a sidewall style that suits the car's original character. A sporty Laser generally reads differently than a conservative Acclaim or Sundance, and a Colt can go either stock or period-custom depending on the build. Event-specific standards vary, so local judging sheets and marque communities remain the best final reference.

In 205/60R15 for the 1991 Plymouth Acclaim, Michelin Primacy 3 and BFGoodrich Radial T/A take very different approaches. The Michelin is a blackwall radial with a W speed rating, a 168 mph ceiling, and a published rim-width range of 5.5 to 7.5 inches. The BFGoodrich Radial T/A uses raised white letters, carries an S speed rating with a 112 mph ceiling, and also fits 5.5 to 7.5 inch rims. The BFGoodrich also publishes a 1,301-pound maximum load at 35 psi.

That means the difference is largely visual and character-driven for an Acclaim owner who has already confirmed the 205/60R15 fitment. Primacy 3 keeps the presentation understated and contemporary, while Radial T/A brings a much more overt period-performance look through its raised white lettering. Neither should be chosen by appearance alone, though, because matching the exact Acclaim wheel package remains the first step.

1991 Plymouth tires can be suitable for highway driving when the tire is the correct size, in sound condition, and used within its stated speed category. Speed-rated examples here include T at 118 mph, H at 130 mph, V at 149 mph, W at 168 mph, and Y at 186 mph depending on size and product. Because every fitment in this group is radial, the conversation is less about bias-ply versus radial limitations and more about matching the right load, condition, and speed category to the car.

On a 1991 Plymouth, normal highway safety often depends as much on the condition of the car itself as on the speed capability printed on the tire. Suspension wear, alignment, brakes, and age-related chassis issues can matter more than a high speed rating on a low-use collector example. A fresh, properly inflated tire in the correct size is part of the answer, but it should be considered alongside the overall mechanical condition of the vehicle.

Inflation pressure for a 1991 Plymouth should follow the vehicle's factory recommendation for the exact model and size, while also respecting the tire's own maximum load and pressure marking where published. Examples here include 185/70R14 at 1,201 pounds at 35 psi on one BFGoodrich application, 155/80R13 at 959 pounds at 35 psi, 165/80R13 at 1,069 pounds at 35 psi, 185/70R13 at 1,135 pounds at 35 psi, 205/60R15 at 1,301 pounds at 35 psi on some products, and up to 1,521 pounds at 32 psi on another 205/60R15 product.

Those figures are load-and-pressure maximums for specific tires, not blanket inflation settings for every 1991 Plymouth. The right approach is to start with the car's original placard or owner's manual for the exact model and then confirm that the chosen reproduction or modern tire is being used within its published limits. Pressure should never be copied from one Plymouth size to another simply because the cars share a model year.

Before a longer drive in a 1991 Plymouth, inspect every tire for visible cracking, cuts, bulges, uneven wear, and objects embedded in the tread. Check cold inflation pressure, confirm the valve stems are sound, and make sure the spare is usable and inflated. If the car uses a product with explicit tubeless marking, verify the wheels seal properly; if older hardware or tube service is involved, inspect that system closely as well.

Tire condition is only one part of a broader pre-trip check on a 1991 Plymouth, but it is the one most likely to strand the car quickly if ignored. A short neighborhood drive does not always reveal a weak sidewall or an aging spare, and heat buildup on a long trip can expose problems that seem minor at first glance. Checking tires before departure is a simple habit that pays off on any older vehicle.
