Chevrolet SS Tires

Chevrolet SS uses two tire sizes across the full 2014 through 2017 run: 245/40R19 and 275/35R19. Both sizes fit 19-inch wheels, but they are not interchangeable because they represent different widths and aspect ratios within the same staggered setup. The available 245/40R19 products fit rim widths from 8.0 to 9.5 inches, while the available 275/35R19 products fit rim widths from 9.0 to 11.0 inches.

The practical takeaway is to identify which axle you are servicing before choosing a tire. A quick look at the existing sidewall, wheel width, and overall front-to-rear setup on the car will keep you from installing the narrower and wider sizes in the wrong positions.

On Chevrolet SS, 245/40R19 is a modern metric radial size. The 245 is the tire’s section width in millimeters, the 40 is the aspect ratio that describes sidewall height as a percentage of width, the R means radial construction, and the 19 is the wheel diameter in inches. That makes it a lower-profile performance tire designed for a 19-inch wheel.

Reading the size correctly matters because a 245/40R19 is not simply any 19-inch tire. The width and profile work together to establish handling balance, clearance, and overall stance, so matching the exact size already fitted to the correct axle is the right starting point for a Chevrolet SS.

A 2014 Chevrolet SS has 245/40R19 and 275/35R19 listed because the model uses a staggered fitment with two different tire sizes in the same year. Both sizes share the same 19-inch rim diameter and both are radial tires, so the difference is not a wheel-diameter change or a bias-versus-radial split. The split comes from the vehicle configuration itself, with one narrower size and one wider size used together.

That means year alone is not enough when replacing just one or two tires on a Chevrolet SS. Check the sidewall on the tire being replaced and compare it to the wheel position on the car so the matching size goes back onto the correct axle.

Chevrolet SS uses 19-inch wheels throughout the 2014 to 2017 model range covered here. Both listed tire sizes, 245/40R19 and 275/35R19, are built for a 19-inch rim, so there is no production change to a different wheel diameter within these years. The difference between the two sizes is width and profile, not rim diameter.

That simplifies fitment compared with older collector cars that changed wheels over time. Even so, it is still smart to verify the wheel on the actual Chevrolet SS, especially if the car has had wheel changes during ownership or if you are sorting out a car with an incomplete service history.

A 2016 Chevrolet SS uses the same two sizes found across the entire 2014 to 2017 run: 245/40R19 and 275/35R19. The correct choice depends on which axle you are replacing, since Chevrolet SS uses a staggered arrangement rather than a single uniform size at all four corners. Both sizes fit 19-inch wheels, but the narrower and wider tires are intended for different wheel-width ranges.

Start by reading the size molded into the sidewall of the tire currently on the wheel you are replacing. Then confirm the wheel width and keep the same size on the same axle, especially if you are replacing only a pair rather than a complete set.

Chevrolet SS tire options here come from BFGoodrich and Nitto. BFGoodrich covers both listed sizes with multiple series, while Nitto appears in the wider 275/35R19 size. All of the listed products are radial blackwall tires sized for 19-inch wheels.

Brand choice becomes a matter of the tire series you prefer and which axle size you need, rather than searching for a special vintage-style construction. If you are trying to keep a matched appearance and behavior front to rear on Chevrolet SS, compare the available series in both sizes before deciding on a combination.

Chevrolet SS tire options here include BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. All are modern radial tires for 19-inch wheels, but they represent different performance-focused series rather than vintage construction types. BFGoodrich appears in both Chevrolet SS sizes, while Nitto NT555 G2 is listed in the wider 275/35R19 size.

For a Chevrolet SS owner, the important step is matching the tire series to how the car is used and keeping size fitment correct at each axle. If you want consistent appearance and response, compare whether the same series is available in both the narrower and wider sizes before mixing different patterns.

A Chevrolet SS should be stored on a clean, dry surface away from direct sunlight, ozone sources, and large temperature swings. Keep the tires inflated to an appropriate pressure for storage and avoid letting the full vehicle weight sit motionless for very long periods without movement. Modern low-profile radial tires can develop temporary flat spotting if they sit for extended intervals.

For a collector-owned Chevrolet SS, periodic movement is helpful even if the car is not driven often. Rolling the car occasionally, keeping it out of harsh light, and maintaining proper inflation will do more for tire life and ride quality than simply relying on tread depth alone.

Tires on a Chevrolet SS should be inspected regularly, not just at annual mileage intervals. Check them before longer drives and during routine service for uneven wear, sidewall damage, punctures, cracking, and any sign that the staggered setup is wearing differently front to rear. Because Chevrolet SS uses lower-profile performance radials, small issues can affect ride and handling more quickly than on taller touring tires.

A practical routine is to inspect the tires every month and any time the car has been stored for a while. Pay close attention to shoulder wear and any mismatch in remaining tread between the two axles, since that can point to alignment, pressure, or rotation limitations within the staggered arrangement.

Chevrolet SS tires should be replaced when age, cracking, impact damage, or internal deterioration becomes a concern, even if the tread still looks usable. Collector-owned cars often age tires out before they wear them out, especially when annual mileage is low and the car spends long periods parked. Any vibration, bulge, persistent air loss, or visible sidewall distress is reason for close evaluation.

For Chevrolet SS, age matters as much as remaining tread because the car’s performance capability can expose weaknesses in an older tire. If the tires are several years old, have hardened noticeably, or show any structural concern, replacement is the prudent step before expecting the car to deliver the balance and grip it was designed to have.

The listed Chevrolet SS tires are modern radial road tires in the correct 19-inch sizes used by the model, so they are intended for normal public-road use when fitted correctly and kept in sound condition. Safety depends on proper size selection, suitable wheel width, correct inflation, and the overall mechanical state of the car. A staggered setup also means the right size must stay on the right axle.

Before regular road use, make sure the Chevrolet SS has no aged-out, damaged, or mismatched tires and that the suspension and alignment are in good order. A powerful rear-wheel-drive sedan will quickly reveal tire issues, so condition and fitment matter just as much as the size molded on the sidewall.

Before driving a Chevrolet SS, check tire pressure, visible tread and sidewall condition, and confirm that the 245/40R19 and 275/35R19 positions have not been mixed up. Look for nails, cuts, bulges, or unusual wear patterns, and make sure each tire is seated on the proper 19-inch wheel width for its size. If the car has been stored, pay attention to vibration during the first miles.

That quick inspection is especially worthwhile on a low-use enthusiast car because storage can hide issues that do not appear at a glance. A few minutes spent checking the Chevrolet SS before a drive can prevent avoidable handling problems and helps preserve the balanced feel that makes the model appealing in the first place.

A Chevrolet SS should only be driven at speeds appropriate to current road conditions, the driver’s ability, and the condition of the specific tires fitted to the car. The listed sizes are modern performance radials, but safe real-world speed depends on far more than the size code alone, including tire age, inflation, suspension condition, alignment, and whether all four tires are properly matched side to side on each axle.

For an enthusiast-owned Chevrolet SS, the sensible approach is to build speed only after the tires are warm, pressures are right, and the car feels stable and consistent. If there is any vibration, tramlining, pull, or uncertainty from the chassis, back off immediately and inspect the tires and alignment before continued use.
