The 1983 Plymouth Reliant sits at an important point in Chrysler history, representing the practical K-car era that reshaped the American family car with front-wheel-drive packaging and everyday usability. Today, these cars appeal to owners who want a clean, honest survivor or a well-kept restoration from the early 1980s. Tire fitment on the 1983 Plymouth Reliant centers on radial sizes 175/75R13, 195/70R13, and 185/70R14, so the first step is confirming which wheel diameter is actually on the car. From there, the choice becomes sidewall appearance, brand and tire series selection, and keeping the tire's proportions in line with the car's intended look and road use.
Which Tire Size Is Right for The 1983 Plymouth Reliant
The 1983 Plymouth Reliant uses three primary tire sizes, and the most important detail is confirming whether the car has 13-inch or 14-inch wheels. All three are radial fitments, but the exact size depends on the wheel setup on the vehicle. Once wheel diameter is verified, the decision shifts to the tire's profile, appearance, and the product choices available in that size.
A 175/75R13 tire uses a 175-millimeter nominal section width, a 75-series aspect ratio, radial construction, and a 13-inch rim. On a 1983 Plymouth Reliant, this is one of the primary modern metric radial fitments and represents a relatively narrow, higher-profile 13-inch setup. Its sizing format will be familiar to modern buyers, even though it belongs to an early 1980s application. This size is worth confirming carefully on a Reliant that still carries stock-style 13-inch wheels, especially if the car's stance, wheel covers, or prior tire replacements have changed over time.
A 185/70R14 tire is a metric radial with a 185-millimeter section width, a 70-series profile, and fitment on a 14-inch rim. For the 1983 Plymouth Reliant, this size matters because it moves the buyer into a different wheel diameter than the 13-inch choices. Available tires in this size include options from BFGoodrich, Avon, Dunlop, Michelin, and Vredestein, with blackwall and wide whitewall presentations across several tire series. It is the size to evaluate when the car is already equipped with 14-inch wheels and the goal is to balance proper fitment with the desired appearance.
A 195/70R13 tire uses a 195-millimeter section width, a 70-series aspect ratio, radial construction, and a 13-inch rim. On the 1983 Plymouth Reliant, it is a wider 13-inch alternative to 175/75R13 while remaining within the same basic metric radial sizing family. In current product choice, this size is available as a BFGoodrich Silvertown Radial with a narrow whitewall, giving it a more restoration-oriented visual character than a plain blackwall. This size deserves a close look when the car has 13-inch wheels and the owner wants a fuller tire appearance without stepping up to a 14-inch rim.
Tire fitment is straightforward across the covered 1983 Plymouth Reliant sub-models because Base, Custom, and SE all share the same three radial size choices. The key detail is not trim level but confirming whether the car has 13-inch or 14-inch wheels before choosing a tire.

1983 Plymouth Reliant Base
The 1983 Plymouth Reliant Base uses the same three primary radial sizes found across the model range: 175/75R13, 195/70R13, and 185/70R14. Tire selection comes down to verifying the wheel diameter on the car, then choosing the sidewall style and product character that suit its appearance and intended use.
The 1983 Plymouth Reliant Custom follows the same basic fitment pattern as the other covered sub-models, with 13-inch and 14-inch radial tire sizes both in play. That makes wheel confirmation the first step, after which the buyer can focus on profile, brand, and sidewall presentation.
The 1983 Plymouth Reliant SE shares the same primary radial tire sizes as the Base and Custom models rather than using a separate fitment. The practical decision is checking whether the car wears 13-inch or 14-inch wheels, then selecting a tire that matches the desired look and road-driving role.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Common 1983 Plymouth Reliant tire questions usually come down to identifying the correct size, confirming 13-inch versus 14-inch wheels, and choosing between available radial styles, brands, and sidewall treatments.
Tire Size & Fitment
What tire size fits a 1983 Plymouth Reliant?
The 1983 Plymouth Reliant uses three primary radial tire sizes: 175/75R13, 195/70R13, and 185/70R14. Those sizes span two wheel diameters, so the car may be set up with either a 13-inch or 14-inch rim depending on its wheel configuration.
The practical step is to confirm the wheel diameter on the actual car before choosing a tire. Once that is settled, compare the exact size already on the vehicle, the tire's profile, and the available sidewall style so the replacement matches both the wheel and the look you want.
What size rim does a 1983 Plymouth Reliant use?
A 1983 Plymouth Reliant can use either a 13-inch or 14-inch rim, depending on which primary tire size is on the car. The 175/75R13 and 195/70R13 sizes use 13-inch rims, while 185/70R14 uses a 14-inch rim.
That difference matters because tire size cannot be chosen by tread width alone. Check the actual wheel diameter stamped on the wheel or confirm the size currently mounted, especially on a car that may have had replacement wheels, trim changes, or previous tire substitutions during its life.
Do all 1983 Plymouth Reliant sub-models use the same tire size?
Base, Custom, and SE versions of the 1983 Plymouth Reliant all share the same group of primary tire sizes: 175/75R13, 195/70R13, and 185/70R14. In other words, the covered sub-models do not split into different tire-size families by trim alone.
Even with shared sub-model fitment, the correct tire still depends on the wheel diameter actually fitted to the car. A Reliant that wears 13-inch wheels needs one of the 13-inch sizes, while a car with 14-inch wheels needs the 185/70R14 size, so wheel confirmation remains the deciding step.
Choosing the Right Tire
What should I consider when choosing a 1983 Plymouth Reliant tire?
Start with the correct primary size for the wheel on the car: 175/75R13, 195/70R13, or 185/70R14. After that, compare construction type, sidewall appearance, rim-width compatibility where stated, and whether the tire's overall character suits a stock-looking driver or a more restoration-oriented presentation.
The 14-inch 185/70R14 category offers the broadest variety, while 195/70R13 currently points to a more specific narrow-whitewall style. Looking at wheel diameter first keeps the choice grounded, then brand, series, load specification, and appearance can be weighed without drifting into a size that belongs on a different rim.
What sidewall styles are available for 1983 Plymouth Reliant tires?
Available sidewall styles for 1983 Plymouth Reliant tires include blackwall, narrow whitewall, and wide whitewall, depending on the size. The 185/70R14 choices include both blackwall and wide whitewall options, while 195/70R13 is available with a narrow whitewall treatment.
Sidewall style affects the car's visual character more than many buyers expect, especially on an early 1980s sedan with simple body lines and full-height sidewalls. A blackwall usually gives a cleaner, more understated look, while whitewall treatments lean more toward a traditional or restoration-minded presentation.
What brands offer tires for the 1983 Plymouth Reliant?
Brands available for 1983 Plymouth Reliant fitments include BFGoodrich, Avon, Dunlop, Michelin, and Vredestein. Brand variety is strongest in 185/70R14, while 195/70R13 is represented by BFGoodrich in the current product mix.
Brand choice should be considered alongside the exact size, sidewall treatment, and tire series rather than as a stand-alone decision. A buyer comparing options for a roadgoing Reliant should also check rim-width recommendations where they are stated so the tire matches the wheel as well as the intended appearance.
Restoration & Appearance
Which tire should I choose for a period-style 1983 Plymouth Reliant?
A period-style 1983 Plymouth Reliant tire starts with the correct wheel diameter and one of the proper primary radial sizes, then narrows down by sidewall appearance. A narrow whitewall 195/70R13 or a wide whitewall 185/70R14 can create a more traditional presentation than a plain blackwall, depending on the car's wheel setup.
The right visual choice depends on whether the car is being preserved as a clean survivor, refreshed as a stock-looking driver, or styled with a slightly dressier period feel. When exact originality matters, compare the tire's appearance with period photography, marque references, and the specific wheel package on the vehicle.
Does correct tire fitment matter for a 1983 Plymouth Reliant restoration?
Correct tire fitment matters on a 1983 Plymouth Reliant restoration because tire diameter, width, and sidewall profile all influence the car's stance and overall presentation. Using one of the proper 13-inch or 14-inch radial sizes keeps the look anchored to the way the Reliant was meant to sit.
Appearance is only part of the equation. A restoration-minded owner should also verify that the wheel diameter is right, that the tire suits the wheel width, and that the finished combination clears the body and suspension without assuming that another size from the same era will behave the same way.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1983 Plymouth Reliant?
Yes. Modifications such as aftermarket wheels, changed wheel widths, suspension lowering, spring replacement, or body alterations can affect tire fitment on a 1983 Plymouth Reliant even when the tire size sounds correct. That is especially important here because the car uses both 13-inch and 14-inch fitment patterns.
A modified Reliant should be checked for wheel diameter, wheel width, and clearance at the fender, suspension, and steering positions before settling on a replacement tire. The safest approach is to confirm the actual setup on the car rather than relying on trim level alone to decide which size belongs there.
What should I inspect before driving a 1983 Plymouth Reliant on new tires?
Before driving a 1983 Plymouth Reliant on new tires, inspect the wheels for the correct diameter and condition, confirm proper inflation, and look over the suspension and steering for obvious wear that could affect how the tire sits and tracks. Lug hardware and valve stems also deserve attention.
A newly mounted tire should also be checked for body and suspension clearance at full steering lock and during normal ride height. On a collector-era car that may sit for long periods, it is smart to watch for air loss, vibration, or rubbing on the first few drives rather than assuming the installation tells the whole story.
How should tires on a collector 1983 Plymouth Reliant be maintained?
Tires on a collector 1983 Plymouth Reliant should be maintained with regular pressure checks, visual inspection for cracking, bulges, cuts, and uneven wear, and periodic attention even if the car is driven only occasionally. Low-use cars can age tires quietly, so mileage alone is not a complete measure of condition.
Storage conditions matter just as much as road use. Keeping the car away from prolonged heat, direct sunlight, standing moisture, and ozone sources helps preserve the tires, while occasional inspection of tread and sidewalls helps catch age-related issues before a local cruise or longer highway drive.
