The 1980 Plymouth TC3 came out of the front-wheel-drive compact era, when hatchback practicality, lighter packaging, and European-influenced proportions were becoming a bigger part of the American small-car market. Its tire fitment reflects that more modern direction, using 13-inch radial sizes rather than older bias-ply conventions. For the 1980 Plymouth TC3, the key sizes are 175/75R13 and 185/70R13, both radial fitments on the same rim diameter. That leaves the real choice centered on confirming which size is on the car, then comparing sidewall style, brand, and tire series. For a stock-looking driver or a restoration-minded hatchback, appearance and wheel compatibility both deserve a careful look.
Which Tire Size Is Right for The 1980 Plymouth TC3
The 1980 Plymouth TC3 uses two primary tire sizes, and both are radial designs for 13-inch wheels. Because the same TC3 Base sub-model can appear with either 175/75R13 or 185/70R13, the first step is confirming the actual wheel-and-tire setup on the car rather than assuming every example left with the same size. Once that is settled, the decision shifts to brand, sidewall appearance, and the type of road use you have in mind.
175/75R13 is a metric radial size in which 175 refers to nominal section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 13 is the wheel diameter in inches. On a 1980 Plymouth TC3, it represents a taller-profile 13-inch radial fitment in a modern sizing format. This size matters most as a fitment checkpoint, since TC3 examples may not all be wearing the same tire today. Before choosing around this specification, confirm the wheel size and compare the tire currently on the car so the replacement matches the setup you are trying to preserve.
185/70R13 is a metric radial size where 185 gives the nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 13 identifies the wheel diameter. For the 1980 Plymouth TC3, this is the size with the broadest visible product selection, including BFGoodrich, Avon, Dunlop, Michelin, and Vredestein options. Available sidewall presentations include blackwall, redline, and wide whitewall, along with tire series such as Silvertown Radial, CR6ZZ, Sport Classic, SP Sport Aquajet, XDX-B, and Sprint Classic. It is the size to evaluate carefully if appearance and product variety are part of the buying decision.
Sub-model fitment is simple here because the covered 1980 Plymouth TC3 Base is the only named sub-model, but tire choice still is not automatic. The Base can use either of the two 13-inch radial sizes, so checking the actual wheel-and-tire combination on the car remains important before selecting a replacement.

1980 Plymouth TC3 Base
The 1980 Plymouth TC3 Base can be found with either 175/75R13 or 185/70R13, and both are radial fitments for 13-inch wheels. That makes the tire decision less about trim level and more about confirming the size already on the car, then choosing the right brand, sidewall style, and overall presentation for your goals.
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.

Available 185/70R13 choices span BFGoodrich, Avon, Dunlop, Michelin, and Vredestein, with blackwall, redline, and wide whitewall sidewall styles. The product grid is most useful for comparing tire series, radial construction details, and rim-width compatibility within this one TC3 fitment size.
Owners of a 1980 Plymouth TC3 usually need to sort out which of the two 13-inch radial sizes is on the car, then compare available brands, sidewall styles, and practical fitment checks before driving on replacement tires.
Tire Size & Fitment
What tire size fits a 1980 Plymouth TC3?
The 1980 Plymouth TC3 uses two primary tire sizes: 175/75R13 and 185/70R13. Both are radial tires designed for 13-inch wheels, and the TC3 Base can be associated with either size rather than one exclusive fitment for every car.
That means the safest first step is checking the tires already on the vehicle and confirming the actual wheel diameter before ordering replacements. On a car of this age, previous owners may have changed wheels or tire sizes, so matching the existing correct setup is more useful than assuming every 1980 TC3 uses the same tire.
What size rim does a 1980 Plymouth TC3 use?
The tire sizes used on the 1980 Plymouth TC3 are built for a 13-inch rim diameter. Both 175/75R13 and 185/70R13 share that same wheel diameter, which makes rim confirmation straightforward at the diameter level.
Rim diameter is only part of the fitment picture, though. Wheel width can still matter, especially when comparing replacement tires with different recommended rim-width ranges, so it is worth checking the actual wheel on the car before choosing among available 13-inch radial options.
What does 185/70R13 mean on a 1980 Plymouth TC3?
185/70R13 is a metric radial tire size. The 185 is the nominal section width in millimeters, 70 is the aspect ratio, the R means radial construction, and 13 is the wheel diameter in inches.
On a 1980 Plymouth TC3, that size matters because it is one of the two correct primary fitments and it also has the strongest product selection. Reading the size correctly helps you separate true fitment from appearance choices such as blackwall, redline, or wide whitewall within the same 13-inch radial category.
Choosing the Right Tire
What should I consider when choosing a 185/70R13 tire for a 1980 Plymouth TC3?
Start with the basics: confirm that 185/70R13 is the size actually used on your 1980 Plymouth TC3, then compare the radial tire options available in that fitment. The visible choices differ by brand, tire series, sidewall style, load figures where stated, and rim-width specifications.
A stock-looking driver may lead you toward one appearance, while a sportier or more European-flavored presentation may point toward another. It also helps to check the wheel width on the car so the tire you choose matches the wheel properly rather than simply sharing the same 13-inch rim diameter.
What sidewall styles are available for 1980 Plymouth TC3 tires?
For the 1980 Plymouth TC3 product assortment in 185/70R13, the available sidewall styles include blackwall, redline, and wide whitewall. Those choices all stay within radial construction, but they change the character of the car's appearance quite a bit.
Blackwall tends to suit a cleaner, more understated presentation, while redline or wide whitewall can push the car toward a more period-style look. The practical step is to decide whether the TC3 is being kept visually stock-leaning, personalized, or restoration-oriented before narrowing the tire series.
What brands offer tires for the 1980 Plymouth TC3?
The 185/70R13 fitment for a 1980 Plymouth TC3 is available from BFGoodrich, Avon, Dunlop, Michelin, and Vredestein. Those brands appear across several radial tire series, giving the TC3 owner more than one way to approach appearance and driving use.
Brand alone should not make the decision. It is smarter to compare the exact tire series, sidewall treatment, stated rim-width range where available, and the kind of look you want on the car. That approach keeps the choice grounded in fitment and presentation rather than name recognition alone.
Restoration & Appearance
Which tire should I choose for a period-style 1980 Plymouth TC3?
A period-style 1980 Plymouth TC3 tire choice starts with using one of the correct primary sizes, then selecting a radial that matches the look you want the car to present. On the 185/70R13 side, that can mean comparing BFGoodrich Silvertown Radial offerings with more traditional or sport-oriented blackwall alternatives.
The right choice depends on whether the goal is a restrained hatchback appearance, a sport-compact flavor, or a restoration-minded presentation. Exact originality claims should be checked against period photos, marque references, or other vehicle-specific documentation when authenticity matters beyond simply using the proper size and general style.
How does tire construction affect the appearance of a restored 1980 Plymouth TC3?
On a restored 1980 Plymouth TC3, construction is less about bias-ply versus radial and more about choosing the correct radial size with the right visual treatment. Since the TC3 uses radial primary fitments, the biggest appearance differences come from sidewall style and tire series rather than a construction conversion.
That makes details such as blackwall, redline, or wide whitewall more important to the finished look of the car. A restoration-oriented owner should treat size, wheel compatibility, and sidewall presentation as a package so the tire supports both the stance of the vehicle and the era impression being pursued.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1980 Plymouth TC3?
Yes, modifications can affect tire fitment on a 1980 Plymouth TC3 even when the tire still has a 13-inch rim diameter. Changes such as aftermarket wheels, different wheel widths, suspension alterations, or body and fender work can influence which of the primary sizes works best on the car.
A TC3 that sits differently than stock or uses non-original wheels should be measured before replacement tires are chosen. Checking wheel width, steering clearance, and space around the tire at full lock is more useful than relying on year-and-model fitment alone once the car has been altered.
What should I inspect before driving a 1980 Plymouth TC3 on new tires?
Before driving a 1980 Plymouth TC3 on new tires, inspect the wheels for damage, confirm the tire size matches the intended setup, and make sure the tires are mounted on the proper 13-inch rims. It is also wise to verify inflation, valve condition, and basic wheel hardware security.
A short initial drive followed by a recheck can reveal rubbing, vibration, or other setup issues early. Older collector-era cars also deserve a look at suspension bushings, alignment condition, and wheel bearings so the new tires are not being asked to compensate for problems elsewhere in the chassis.
How should tires on a collector 1980 Plymouth TC3 be maintained?
Tires on a collector 1980 Plymouth TC3 should be checked regularly for pressure, tread condition, cracking, bulges, cuts, and signs of slow air loss. Even a low-mileage hatchback that spends much of its time parked can age its tires long before the tread looks worn out.
Storage conditions matter just as much as mileage. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires, and occasional inspection of the sidewalls and contact patch helps catch problems early before a weekend drive or longer outing.
