The 2018 Chevrolet Corvette sits firmly in the modern performance era, where sharp chassis tuning, serious grip, and staggered wheel-and-tire packages are part of the car’s character rather than an afterthought. On this Corvette, tire selection starts with identifying the exact front and rear fitment used by the Stingray, Grand Sport, or Z06 configuration. The primary fitments here are all radial metric sizes on 19-inch front and 20-inch rear wheels. Available choices also vary by brand, tire series, and sidewall treatment, including blackwall, raised white letter, and redline options in some rear applications. For owners, the real task is matching the correct axle position, wheel size, and intended appearance before choosing a tire.
Which Tire Size Is Right for The 2018 Chevrolet Corvette
The 2018 Chevrolet Corvette uses four primary tire sizes, and they are tied to both sub-model and axle position. Front and rear fitments differ, and the car uses both 19-inch and 20-inch rim diameters, so the first step is confirming whether the Corvette is a Stingray, Grand Sport, or Z06 and then matching the tire to the correct end of the car.
A 285/30R19 tire is a metric radial size with a 285-millimeter section width, a 30-series profile, and fitment on a 19-inch rim. On the 2018 Chevrolet Corvette, this size is used as a front fitment on Grand Sport and Z06 configurations, where a wide contact patch and low-profile construction are part of the package. This is a modern radial performance size rather than a vintage sizing format. Choosing it correctly means confirming that the tire is intended for the front axle and that the Corvette still carries the proper 19-inch wheel setup for that application.
A 335/25R20 tire is a very wide metric radial with a 335-millimeter section width, a 25-series profile, and a 20-inch rim diameter. On the 2018 Chevrolet Corvette, this size serves as the rear fitment for Grand Sport and Z06 models, making it a specialized staggered application rather than a universal Corvette tire. Its low-profile radial construction reflects the car’s modern high-performance layout. This size should be evaluated as a rear-specific fitment, with careful attention to wheel width, wheel diameter, and whether the car remains on the correct factory-style staggered setup.
A 245/35R19 tire is a metric radial size that combines a 245-millimeter section width with a 35-series profile on a 19-inch wheel. On the 2018 Chevrolet Corvette, this is the front tire size for the Stingray, and available products include blackwall options from BFGoodrich and Nitto across g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 series. Those choices give the buyer some room to compare product character within the same fitment. The practical priority is keeping this size on the front axle and confirming compatibility with the Corvette’s 19-inch front wheel.
A 285/30R20 tire is a metric radial with a 285-millimeter section width, a 30-series profile, and fitment on a 20-inch rim. On the 2018 Chevrolet Corvette, this size is used at the rear of the Stingray, where it pairs with a narrower 19-inch front tire in a staggered arrangement. Product choices include blackwall, raised white letter, and redline sidewall treatments, with Nitto and Pro-Trac options available in this fitment. It is the right size to evaluate when the car needs a Stingray rear tire and the owner wants to balance performance fitment with a specific sidewall presentation.
Sub-model fitment matters on the 2018 Chevrolet Corvette because tire sizes change by both model line and axle position. Stingray, Grand Sport, and Z06 do not all share the same front and rear setup, so the right starting point is identifying the exact configuration before selecting a tire.

2018 Chevrolet Corvette Grand Sport Front
The 2018 Chevrolet Corvette Grand Sport Front uses a 285/30R19 radial tire. That makes front-axle confirmation especially important, since this size is wider than the Stingray front fitment and should be matched to the proper 19-inch wheel setup.
The 2018 Chevrolet Corvette Grand Sport Rear uses a 335/25R20 radial tire. Rear tire selection here is part of a dedicated staggered package, so the buyer should confirm the 20-inch rear wheel and avoid treating this as a general Corvette rear size.
The 2018 Chevrolet Corvette Stingray Front uses a 245/35R19 radial tire. Available choices in this size include blackwall performance tires from BFGoodrich and Nitto, making the decision more about product selection and intended use than about alternate primary sizes.
The 2018 Chevrolet Corvette Stingray Rear uses a 285/30R20 radial tire. This fitment gives the owner some added choice in sidewall appearance, so the main job is matching the rear axle and 20-inch wheel before comparing blackwall, RWL, or redline options.
The 2018 Chevrolet Corvette Z06 Front uses a 285/30R19 radial tire. Since that matches the Grand Sport front size, the key step is still verifying front-wheel application and keeping the tire matched to the correct axle position rather than choosing by size alone.
The 2018 Chevrolet Corvette Z06 Rear uses a 335/25R20 radial tire. This is a specialized rear fitment within the Corvette range, so tire selection should begin with confirming the exact rear wheel and preserving the intended staggered front-to-rear relationship.
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 2018 Chevrolet Corvette?
The 2018 Chevrolet Corvette uses four primary tire sizes: 245/35R19, 285/30R20, 285/30R19, and 335/25R20. The exact size depends on both sub-model and axle position, with Stingray using 245/35R19 front and 285/30R20 rear, while Grand Sport and Z06 use 285/30R19 front and 335/25R20 rear.
That means the first step is not just confirming the year and model name, but also identifying whether the car is a Stingray, Grand Sport, or Z06 and whether the tire is for the front or rear. On a staggered Corvette setup, using the right size in the right location matters just as much as matching the correct rim diameter.
What size rim does a 2018 Chevrolet Corvette use?
The 2018 Chevrolet Corvette uses both 19-inch and 20-inch rim diameters. The 245/35R19 and 285/30R19 front tires mount on 19-inch wheels, while the 285/30R20 and 335/25R20 rear tires mount on 20-inch wheels, depending on the specific Corvette configuration.
That split rim-diameter layout makes wheel confirmation essential before choosing a tire. A Corvette with original-style staggered wheels needs the tire matched to the proper rim diameter and axle location, and any car with aftermarket wheels should be measured carefully so the tire choice still works with the actual wheel size and overall setup.
Why does the 2018 Chevrolet Corvette have more than one tire size?
The 2018 Chevrolet Corvette has more than one tire size because fitment changes by both sub-model and axle position. Stingray, Grand Sport, and Z06 do not share one universal front-and-rear package, and the car uses staggered sizing with different front and rear dimensions as part of its overall performance layout.
For the owner, that means tire selection starts with the exact version of the car rather than with Corvette fitment in general. Once the sub-model is confirmed, the next step is matching the tire to the front or rear axle and making sure the wheel diameter still corresponds to the intended size, especially on modified cars.
Choosing the Right Tire
What should I consider when choosing a 245/35R19 tire for a 2018 Chevrolet Corvette?
A 245/35R19 tire on a 2018 Chevrolet Corvette is the Stingray front fitment, so selection starts with keeping that size on the correct axle and confirming the 19-inch front wheel. Available options in this size include blackwall radial tires from BFGoodrich and Nitto across different performance-oriented series.
The practical choice comes down to matching the tire to the way the car is used and the product specifications that matter most to the owner. Rim-width compatibility, load capacity where stated, sidewall design, and overall brand-and-series preference all deserve attention, but the tire still needs to stay aligned with the Corvette’s front-wheel application.
What sidewall styles are available for 2018 Chevrolet Corvette tires?
Sidewall style depends on the Corvette tire size being considered. The available 245/35R19 front options are blackwall tires, while the 285/30R20 rear fitment for the Stingray includes blackwall, RWL, and redline choices, giving that rear application more visual variety than the front.
That matters most for owners who want the tire to influence the car’s overall presentation as much as its fitment. A blackwall keeps the look understated, while raised white letter or redline sidewalls create a more pronounced visual statement, but those appearance choices still need to be matched to the correct rear size and wheel.
What brands offer tires for the 2018 Chevrolet Corvette?
Available brands for 2018 Chevrolet Corvette fitments here include BFGoodrich, Nitto, and Pro-Trac. BFGoodrich and Nitto appear in the 245/35R19 front size, while Nitto and Pro-Trac appear in the 285/30R20 rear size, with differences in series and sidewall treatment across those offerings.
Brand choice is only one part of the decision, since each product also needs to line up with the correct tire size, axle position, and wheel diameter. Once the fitment is confirmed, comparing tire series, sidewall style, weight, and any stated rim-width or load details gives a more useful basis for selecting among the available options.
Restoration & Appearance
Which tire should I choose for a period-style 2018 Chevrolet Corvette?
A period-style approach on a 2018 Chevrolet Corvette still begins with the correct modern radial size for the exact sub-model and axle position. Since this Corvette uses contemporary low-profile metric fitments, the visual decision is less about vintage construction and more about choosing among the available tire series and sidewall presentations within the proper size.
For a cleaner late-model appearance, a blackwall is the most understated choice in the available fitments. Owners who want more visual emphasis at the rear can also consider RWL or redline options in 285/30R20, but the appearance goal should never override the need to keep the tire matched to the right Corvette configuration and wheel diameter.
Does correct tire fitment matter for a 2018 Chevrolet Corvette restoration?
Correct tire fitment matters on a 2018 Chevrolet Corvette restoration because the car’s stance, wheel relationship, and overall presentation depend on the right front and rear sizes. With staggered 19-inch front and 20-inch rear applications across different Corvette sub-models, the tire choice has a visible effect as well as a mechanical one.
Even on a cosmetic restoration, it helps to confirm the exact Stingray, Grand Sport, or Z06 setup before choosing tires. A visually appealing sidewall treatment can complement the car, but the size itself remains the foundation, especially if originality of configuration and proper front-to-rear proportion are part of the restoration objective.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Chevrolet Corvette?
Yes, modifications can affect tire fitment on a 2018 Chevrolet Corvette. Aftermarket wheels, suspension changes, altered ride height, spacers, or body changes can all change the amount of room available for the factory-style front and rear tire sizes, especially on a car that already uses low-profile staggered fitments.
A modified Corvette should be checked for actual wheel diameter, wheel width, and clearance at steering lock and through suspension travel before replacing tires. Even when the tire size matches a common Corvette application, the real fit depends on the car as it sits now rather than on how it left the factory.
What should I inspect before driving a 2018 Chevrolet Corvette on new tires?
Before driving a 2018 Chevrolet Corvette on new tires, inspect the wheels for damage, verify that the front and rear sizes were mounted in the correct positions, and confirm that inflation pressures are set properly. It also helps to look over the valve stems, tread surfaces, and sidewalls after installation for any obvious issues.
A short initial check for rubbing, vibration, or unusual steering response is especially worthwhile on a staggered Corvette setup. Any car with previous wheel, brake, or suspension changes deserves an extra clearance review, since low-profile front and rear tires leave less margin for mismatch than more forgiving collector-vehicle fitments.
How often should tires on a 2018 Chevrolet Corvette be inspected?
Tires on a 2018 Chevrolet Corvette should be inspected regularly, not just when tread wear becomes obvious. A modern performance tire can still develop problems from impacts, underinflation, irregular wear, or long periods of sitting, so frequent visual checks are a sensible part of ownership.
Monthly pressure checks and routine inspections for cuts, punctures, bulges, and uneven wear patterns are a good habit, especially since front and rear tires on the Corvette are different sizes and do different work. Any change in ride quality, steering feel, or road noise is a reason to inspect the tires and wheels more closely.
