The 1978 Toyota Corolla sits in the sweet spot where compact Japanese cars became genuinely mainstream in the U.S., valued today for simple engineering, light weight, and honest late-1970s character. Whether the goal is a tidy sedan, wagon, or sportier SR-5 variant, tire choice has a real effect on both appearance and road feel. This Corolla uses several 13-inch fitments, including a traditional 6.15-13 bias-ply option and radial sizes such as 155R13, 165R13, and 185/70R13. Available choices range from blackwall touring-style radials to redline and wide whitewall treatments in selected sizes. The key is matching the exact sub-model first, then deciding whether originality, period-style appearance, or everyday drivability matters most.
Which Tire Size Is Right for The 1978 Toyota Corolla
The 1978 Toyota Corolla uses four primary tire sizes, and the right one depends on the exact sub-model rather than wheel diameter, since all of them use a 13-inch rim. Some versions use a traditional bias-ply fitment, while others use radial sizes in either Euro-metric or modern metric form. The first step is confirming whether the car is a 1200 Sedan, 1600 Sedan & Wagon, SR-5, or 1600 SR-5 Liftback.
155R13 is a Euro-metric radial size in which 155 refers to nominal section width in millimeters, R identifies radial construction, and 13 is the wheel diameter in inches. On the 1978 Toyota Corolla, this size is part of the 1200 Sedan fitment and reflects the slim, efficient tire proportions common on compact imports of the period. Available choices include Michelin and Dunlop blackwall radials in series such as XAS-FF and SP Sport Aquajet. It suits buyers who want to stay close to the Corolla's narrow radial look while keeping a 13-inch wheel setup.
6.15-13 is a numeric bias-ply size, with the 6.15 indicating nominal section width in inches and the 13 identifying the rim diameter. For the 1978 Toyota Corolla, this is the bias-ply fitment associated with the 1200 Sedan and represents an older sizing convention than the radial alternatives used elsewhere in the lineup. Bias-ply construction matters here because it affects both the car's period presentation and the feel of the tire compared with later radial designs. This size is most relevant for restoration-minded owners who want a traditional fitment rather than a modernized radial approach.
185/70R13 is a metric radial size in which 185 is the nominal section width in millimeters, 70 is the aspect ratio, R means radial construction, and 13 is the wheel diameter. On the 1978 Toyota Corolla, this size belongs to the SR-5 and 1600 SR-5 Liftback, giving those models a broader radial fitment than the narrower sedan sizes. Product choice is especially varied here, with BFGoodrich, Avon, Dunlop, Michelin, and Vredestein options, plus blackwall, redline, and wide whitewall sidewall treatments. This is the size to evaluate carefully if the goal is balancing sportier appearance, brand preference, and wheel-width compatibility.
165R13 is a Euro-metric radial size that uses 165 as the nominal section width in millimeters, with R for radial construction and 13 for the rim diameter. The 1978 Toyota Corolla 1600 Sedan & Wagon uses this size, placing it between the narrower 155R13 fitment and the wider 185/70R13 used on SR-5 versions. Michelin and Dunlop blackwall radials are available in this size, including XAS, XAS-FF, and SP Sport Aquajet lines. It is a useful fitment for owners who want a period-appropriate radial presentation without stepping into the wider SR-5 tire size.
Sub-model fitment matters on the 1978 Toyota Corolla because tire size changes across the lineup even though the cars share a 13-inch wheel diameter. Confirming the exact body and trim version is the quickest way to narrow the correct size and decide whether the car belongs on a bias-ply or radial tire.

1978 Toyota Corolla 1200 Sedan
The 1978 Toyota Corolla 1200 Sedan is the only covered sub-model with both a radial and a bias-ply primary fitment, using either 155R13 or 6.15-13. That makes this version especially important to identify before choosing between a more traditional restoration-style presentation and a narrower radial setup.
The 1978 Toyota Corolla 1600 SR-5 Liftback uses 185/70R13 radial tires on a 13-inch rim. Tire selection here centers less on basic size fitment and more on comparing sidewall style, brand, tire series, and wheel-width suitability within that radial size.
The 1978 Toyota Corolla 1600 Sedan & Wagon uses the 165R13 radial size. For this sub-model, the decision is mainly about choosing among period-style blackwall radial options while keeping the correct 13-inch wheel format and a size appropriate to the sedan and wagon setup.
The 1978 Toyota Corolla SR-5 uses 185/70R13 radial tires, matching the sportier fitment also found on the 1600 SR-5 Liftback. That gives the buyer several radial product choices and a broader appearance range than the narrower Corolla sedan tire sizes.
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.
Best 1978 Toyota Corolla Tires for Sale
Available 13-inch Corolla tires span Michelin, Dunlop, BFGoodrich, Avon, and Vredestein, with the broadest variety in 185/70R13. Depending on size, buyers can compare blackwall, redline, and wide whitewall radials across several vintage-inspired tire series and rim-width ranges.
Common 1978 Toyota Corolla tire questions usually come down to exact sub-model fitment, 13-inch wheel compatibility, bias-ply versus radial construction, and how to choose among the available blackwall, redline, or whitewall options.
Tire Size & Fitment
What tire size fits a 1978 Toyota Corolla?
A 1978 Toyota Corolla does not use one universal tire size across every version. Covered fitments include 155R13, 6.15-13, 165R13, and 185/70R13, all on 13-inch rims. The 1200 Sedan uses 155R13 radial or 6.15-13 bias-ply, the 1600 Sedan & Wagon uses 165R13, and the SR-5 and 1600 SR-5 Liftback use 185/70R13.
The practical step is identifying the exact sub-model before choosing a tire. Once that is settled, compare the current wheel size and the tire construction already on the car, especially on a 1200 Sedan where both bias-ply and radial fitments are in play. Cars with changed wheels, suspension work, or prior tire substitutions should be measured rather than assumed.
What size rim does a 1978 Toyota Corolla use?
The covered tire fitments for the 1978 Toyota Corolla all use a 13-inch rim diameter. That includes the 155R13, 6.15-13, 165R13, and 185/70R13 sizes. Even though the Corolla lineup uses more than one tire size, wheel diameter stays consistent across these fitments.
Rim diameter alone does not settle the fitment question, because width and the exact sub-model still matter. A 13-inch wheel can physically exist in several widths, and some tire products carry specific rim-width ranges that should be respected. If the car has aftermarket wheels, verify both diameter and width before selecting a tire, especially when moving between narrower sedan sizes and the wider SR-5 fitment.
Why does the 1978 Toyota Corolla have more than one tire size?
The 1978 Toyota Corolla has more than one tire size because fitment changes by sub-model and by tire construction. The 1200 Sedan carries either a narrow 155R13 radial or a 6.15-13 bias-ply, the 1600 Sedan & Wagon uses 165R13, and the SR-5 models use 185/70R13 radials. Those differences reflect distinct configurations within the Corolla range.
That variation means tire choice should start with the exact badge and body style rather than a general Corolla label. It also helps explain why one owner's car may wear a much narrower tire than another 1978 Corolla sitting beside it. Before replacing anything, confirm the wheel and compare the tires currently on the car against the intended sub-model fitment.
Choosing the Right Tire
What should I consider when choosing a tire for a 1978 Toyota Corolla?
Start with the correct sub-model and tire size, because the 1978 Toyota Corolla uses several distinct 13-inch fitments. After size, the next decisions are construction type, brand, tire series, and whether the car's look should stay understated with a blackwall or lean more toward a period-custom presentation where that sidewall style exists.
Product details matter once the size is settled. Some Corolla tires have stated rim-width ranges, and some show different load figures, weights, or speed-oriented sizing details. A lightly restored sedan, a driver-grade wagon, and an SR-5 with sportier intent may all point toward different choices even within the same size, so compare the tire's appearance and specifications against the way the car will actually be used.
What sidewall styles are available for 1978 Toyota Corolla tires?
Blackwall is the most common sidewall style across 1978 Toyota Corolla tire offerings, especially in 155R13 and 165R13. In 185/70R13, the choices broaden to include blackwall, redline, and wide whitewall versions. That makes the SR-5 fitment the most appearance-sensitive size in the lineup.
Sidewall style changes the look of the car more than the fitment itself, so it should be chosen with the Corolla's intended presentation in mind. A blackwall keeps a clean import-era appearance, while redline or wide whitewall options create a much stronger visual statement. Appearance still comes second to correct size and wheel compatibility, especially if the car no longer wears its original wheel setup.
What brands offer tires for the 1978 Toyota Corolla?
Available 1978 Toyota Corolla tire brands include Michelin, Dunlop, BFGoodrich, Avon, and Vredestein, depending on the size. Michelin and Dunlop appear in the narrower 155R13 and 165R13 sizes, while 185/70R13 opens up the broadest mix of brands and series for SR-5 applications.
Brand choice is best treated as one part of a larger comparison rather than the first decision. Once the correct size is confirmed, look at whether the tire is offered in the sidewall style you want, whether the series matches the car's character, and whether the wheel width falls inside the stated range when one is given. That approach keeps the selection grounded in fitment rather than logo preference.
Restoration & Appearance
Which tire should I choose for a period-style 1978 Toyota Corolla?
A period-style 1978 Toyota Corolla tire starts with the correct size for the exact sub-model. That could mean a 6.15-13 bias-ply or 155R13 radial on a 1200 Sedan, 165R13 on a 1600 Sedan & Wagon, or 185/70R13 on an SR-5. The right visual direction depends on whether the goal is a traditional late-1970s compact look or a more individualized period flavor.
Construction and sidewall treatment both influence the result. Bias-ply choice leans toward an older presentation, while blackwall radials keep a clean, era-appropriate look for many restored drivers. If exact originality matters beyond general period style, compare the intended tire against marque-specific restoration references, surviving vehicle examples, and trim-level details before settling on a brand or sidewall treatment.
How does tire construction affect the appearance of a restored 1978 Toyota Corolla?
Tire construction changes more than ride feel on a restored 1978 Toyota Corolla; it also changes the visual character of the car. The 1200 Sedan is the clearest example because it can use either a 6.15-13 bias-ply or a 155R13 radial. Bias-ply tires usually present a more traditional vintage look, while radials give the car a more familiar late-1970s driver appearance.
That visual difference matters most when the restoration aims for a particular era impression. A narrow blackwall radial can look entirely appropriate on a usable street car, while a bias-ply may better suit a more traditional presentation. The key is avoiding a mismatch between tire style, wheel choice, and the rest of the build, especially on a compact car where tire proportions are easy to notice.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1978 Toyota Corolla?
Yes, modifications can affect tire fitment on a 1978 Toyota Corolla even when the tire size itself is correct for the sub-model. Aftermarket wheels can change width or offset, and suspension changes can alter fender and steering clearance. Those factors matter most when a car has moved away from its original wheel setup or sits lower than stock.
A modified Corolla should be checked at full steering lock and through normal suspension travel before settling on a replacement tire. The concern is not only wheel diameter, since all covered sizes use 13-inch rims, but also whether the chosen tire and wheel combination clears the body and suspension. That is especially important when using wider 185/70R13 tires on cars that have been altered.
What should I inspect before driving a 1978 Toyota Corolla on new tires?
Before driving a 1978 Toyota Corolla on new tires, inspect the wheels for damage, verify the rim diameter and width, and make sure the tire size matches the exact sub-model. Then check inflation, confirm valve stem condition, and look for basic clearance around the fenders, steering components, and suspension once the car is back on the ground.
It also helps to evaluate the rest of the car's running condition before putting miles on fresh tires. Worn shocks, loose steering parts, poor alignment, or old bushings can make a correctly sized tire behave badly. On a collector Corolla that sits for long periods, a short test drive followed by a second pressure and clearance check is a sensible way to catch issues early.
How should tires on a collector 1978 Toyota Corolla be maintained?
Tires on a collector 1978 Toyota Corolla should be kept properly inflated, inspected regularly for cracking, cuts, bulges, uneven wear, and slow air loss, and protected from long periods of direct sun, heat, moisture, and ozone exposure. Low-use cars often age their tires before they wear them out, so condition matters as much as tread depth.
Regular movement helps prevent flat spotting and gives the owner a chance to notice changes in ride or steering before they become larger problems. Seasonal checks are worthwhile even when the car is stored indoors. A Corolla that has sat for months should have its tire pressures, sidewalls, and wheel hardware reviewed before returning to normal road use, especially if the tires are several years old.
