The 1989 Chevrolet Corvette sits at an interesting point in Corvette development, blending late-C4 chassis sophistication with the sharper handling expectations of the era. It is also the year that brings a split fitment into focus, with the Base model and ZR1 front using 275/40R17 radials while the ZR1 rear uses a wider 315/35R17 radial on the same 17-inch wheel diameter. That makes tire selection less about old bias-ply versus radial decisions and more about matching the right size to the right position, then choosing among blackwall, raised white letter, or redline presentations. For restoration-minded owners and drivers alike, wheel width, intended use, and overall stance all matter.
Which Tire Size Is Right for The 1989 Chevrolet Corvette
The 1989 Chevrolet Corvette uses two primary tire sizes, and choosing correctly starts with identifying the exact configuration. Both sizes are radial tires for 17-inch rims, but fitment changes by sub-model and position: 275/40R17 serves the Base model and ZR1 front, while 315/35R17 is used on the ZR1 rear. The real decision is matching the correct size to the car's setup, then comparing sidewall style, tire series, and wheel-width compatibility.
In 275/40R17, the 275 identifies section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 17 is the wheel diameter in inches. On the 1989 Chevrolet Corvette, this size is used where a lower-profile modern radial is part of the vehicle's intended fitment story rather than a vintage conversion. Available choices include blackwall designs from M&H Racemaster, BFGoodrich, Nitto, and Michelin, plus Pro-Trac Street Pro III options in raised white letter and redline form. It is the key size to confirm for Base models and for the front position on the ZR1.
In 315/35R17, the 315 refers to section width in millimeters, 35 is the aspect ratio, R marks radial construction, and 17 denotes the wheel diameter. This is the wider rear tire used on the 1989 Chevrolet Corvette ZR1, so its role is tied to that specific rear-wheel fitment rather than every Corvette configuration from the year. Product choices include blackwall and Pro-Trac Street Pro III versions with raised white letter or redline sidewalls. It is the size to evaluate when the car requires the broader rear footprint and the wheel width matches the tire's intended range.
Sub-model fitment matters on the 1989 Chevrolet Corvette because tire size changes between the standard car and the ZR1 rear position. The wheel diameter remains 17 inches throughout, but the correct tire still depends on confirming whether the car is a Base model or a ZR1 and, in the ZR1's case, whether the tire is for the front or rear.

1989 Chevrolet Corvette Base
The 1989 Chevrolet Corvette Base uses the 275/40R17 radial size. Tire selection centers on choosing the right series and sidewall treatment for the car's intended look and use, while also confirming that the existing wheels match the tire's fitment needs.
The 1989 Chevrolet Corvette ZR1 Front uses the 275/40R17 radial size. That keeps the front selection focused on the correct lower-profile 17-inch fitment, with choices available in blackwall, raised white letter, and redline presentations depending on the appearance you want.
The 1989 Chevrolet Corvette ZR1 Rear uses the wider 315/35R17 radial size. Rear tire selection should focus on preserving the proper staggered setup, checking wheel width carefully, and choosing a sidewall style or tire series that suits the car's road or display 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.

Tire Size & Fitment
What tire size fits a 1989 Chevrolet Corvette?
The 1989 Chevrolet Corvette uses two primary tire sizes: 275/40R17 and 315/35R17. The Base model uses 275/40R17, the ZR1 front also uses 275/40R17, and the ZR1 rear uses 315/35R17 as part of its staggered setup.
That means the first step is confirming whether the car is a Base model or a ZR1, and on a ZR1, whether the tire is for the front or rear. Both sizes fit 17-inch wheels, but the widths are very different, so wheel width and clearance should be checked before replacing mismatched or modified tires.
What size rim does a 1989 Chevrolet Corvette use?
The 1989 Chevrolet Corvette uses 17-inch rims with both primary tire sizes. The 275/40R17 and 315/35R17 fitments are both built around the same 17-inch wheel diameter, even though the tire widths and aspect ratios differ.
Wheel diameter is only part of the fitment picture, especially on a car with staggered sizing like the ZR1. A 17-inch wheel still needs the correct width for the tire being used, so it is smart to verify the actual wheel setup before choosing between available 275 and 315 section-width tires.
Do all 1989 Chevrolet Corvette sub-models use the same tire size?
No. The 1989 Chevrolet Corvette Base uses 275/40R17, the ZR1 front uses 275/40R17, and the ZR1 rear uses 315/35R17. The change appears at the rear of the ZR1, where the car uses a wider tire than the front.
That distinction matters because a wider rear tire changes more than appearance. It affects wheel-width requirements and the overall staggered setup, so owners should confirm the sub-model and axle position before ordering replacements, especially if the car has had wheel changes or has been stored with mismatched tires.
Choosing the Right Tire
What should I consider when choosing a 275/40R17 tire for a 1989 Chevrolet Corvette?
Start with the car's exact fitment role. On a 1989 Chevrolet Corvette, 275/40R17 is used on the Base model and on the front of the ZR1, so the right tire needs to match that position as well as the 17-inch wheel diameter.
After size is confirmed, compare sidewall presentation, tire series, and wheel-width compatibility. Choices in this size include blackwall options from several brands along with Pro-Trac raised white letter and redline versions, so the decision often comes down to whether the car is being set up for a more modern road look or a stronger period-inspired appearance.
What sidewall styles are available for 1989 Chevrolet Corvette tires?
1989 Chevrolet Corvette tires are available in several sidewall styles depending on size and product line. Blackwall choices are common in both 275/40R17 and 315/35R17, while Pro-Trac Street Pro III options add raised white letter and redline sidewalls.
Sidewall choice mainly affects the car's visual character rather than the basic size fitment. A blackwall tends to suit a more understated late-model appearance, while raised white letter or redline treatments create a more custom or period-inspired presentation, so the best choice depends on how closely the car is being styled to a particular look.
What brands offer tires for the 1989 Chevrolet Corvette?
Tires for the 1989 Chevrolet Corvette are available from M&H Racemaster, BFGoodrich, Nitto, Michelin, and Pro-Trac. Brand availability varies by size, with the 275/40R17 fitment offering the broadest spread of product lines and the 315/35R17 rear size carrying a narrower selection.
The practical difference is not just the brand name but the type of tire each brand brings to the size. Some options emphasize a street radial format, one 275/40R17 option is a drag race tire, and Pro-Trac adds sidewall styling choices, so the car's use and presentation should guide the comparison.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Chevrolet Corvette?
A period-style 1989 Chevrolet Corvette should stay with its correct primary radial size for the specific model and position: 275/40R17 for the Base and ZR1 front, or 315/35R17 for the ZR1 rear. From there, the appearance decision comes down to the tire series and sidewall treatment available in that exact size.
A blackwall keeps the presentation closer to a typical late-1980s performance look, while raised white letter or redline versions can lean more custom. Owners chasing strict restoration authenticity should compare tire appearance against period photos, marque references, and the car's intended finished look before making a final choice.
How does tire construction affect the appearance of a restored 1989 Chevrolet Corvette?
On a 1989 Chevrolet Corvette, construction is not a bias-ply-versus-radial restoration issue because the primary fitments are radial tires. The appearance difference comes more from the tire's profile, sidewall treatment, and series character than from switching between historic construction types.
That makes size accuracy and sidewall styling especially important on a restored car. A correct 17-inch radial fitment preserves the stance the chassis was built around, while blackwall, raised white letter, or redline choices can shift the visual tone noticeably, so the tire should support the car's intended era-specific presentation rather than fight it.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Chevrolet Corvette?
Yes. A 1989 Chevrolet Corvette may no longer have its original wheel and suspension setup, and that can affect how 275/40R17 or 315/35R17 tires sit on the car. Changes in wheel width, offset, ride height, or suspension components can all influence fitment.
That is especially important on the ZR1 because the rear uses a wider 315/35R17 tire. Even with the correct nominal size, clearance at the fender, inner wheelhouse, and suspension should be confirmed on any modified car, and the actual wheel dimensions should be checked before selecting a replacement tire.
What should I inspect before driving a 1989 Chevrolet Corvette on new tires?
Check that the new tires match the car's required size and position, then inspect the wheels, valve stems, and general mounting condition before road use. It also makes sense to look over tread seating, sidewalls, and inflation so the car starts from a sound baseline.
A 1989 Chevrolet Corvette can be sensitive to mismatched front and rear fitment, so verify that the Base or ZR1 setup has been preserved correctly. Suspension wear, alignment condition, and any rubbing marks around the wheel openings are worth catching early, particularly if the car has spent long periods parked or has aftermarket wheels.
How should tires on a collector 1989 Chevrolet Corvette be maintained?
Collector-car tires on a 1989 Chevrolet Corvette should be inspected regularly for air loss, sidewall cracking, cuts, bulges, and uneven wear. Even if mileage is low, age and storage conditions still matter, especially on a performance car that may sit for long stretches between drives.
Proper inflation, clean storage, and occasional movement help reduce flat-spotting and general deterioration. Keeping the car away from prolonged heat, direct sunlight, and ozone sources is helpful, and owners should give extra attention to matching front and rear sizes correctly so the staggered setup remains consistent when the car returns to the road.
