The 2015 Chevrolet SS delivered full-size rear-wheel-drive V8 performance in a modern sedan package, giving enthusiasts a distinctly Australian-developed sport sedan with American badge appeal. It occupies a narrow but interesting place in Chevrolet history, blending everyday practicality with serious road presence and balanced chassis character. Tire fitment is split front to rear, with 245/40R19 in front and 275/35R19 in back, both in radial construction on 19-inch rims. Available choices center on blackwall performance-oriented tires from BFGoodrich and Nitto across several series. For this car, the key is preserving the staggered setup while matching the tire to your driving style, wheel specs, and overall vehicle condition.
Which Tire Size Is Right for The 2015 Chevrolet SS
The 2015 Chevrolet SS uses two primary tire sizes, and the difference is tied directly to its front and rear fitment. Both are radial tires for 19-inch wheels, so the first step is confirming whether you are replacing the front pair, the rear pair, or all four tires while keeping the factory-style staggered arrangement intact.
245/40R19 is a metric radial size where 245 identifies the section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter in inches. On the 2015 Chevrolet SS, this size serves the front position and supports the car's staggered tire layout. Available options are centered on BFGoodrich blackwall performance tires in g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. This is the size to evaluate when replacing the front tires and confirming that wheel width remains within the tire's intended range.
275/35R19 is a metric radial size with a 275-millimeter nominal section width, a 35-series profile, radial construction, and a 19-inch rim diameter. On the 2015 Chevrolet SS, this is the rear tire size and it provides the wider half of the car's staggered setup. Choices include blackwall tires from BFGoodrich and Nitto, with several performance-oriented series available in this fitment. This rear size matters any time traction balance, wheel-width compatibility, or proper front-to-rear sizing needs to be maintained on an unmodified or carefully verified setup.
Sub-model fitment on the 2015 Chevrolet SS is straightforward, but front and rear positions use different sizes. Checking whether you are working with the Base Front or Base Rear fitment matters because the car does not use the same tire size at all four corners.

2015 Chevrolet SS Base Front
The 2015 Chevrolet SS Base Front uses the narrower front tire fitment in radial construction on a 19-inch wheel. That makes front tire selection a matter of choosing the right performance-oriented 245/40R19 option while preserving the intended staggered relationship to the rear.
The 2015 Chevrolet SS Base Rear uses the wider rear tire fitment in radial construction on a 19-inch wheel. Rear tire selection should focus on the correct 275/35R19 size, wheel compatibility, and maintaining the front-to-rear balance designed into the car's staggered setup.
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 2015 Chevrolet SS?
The 2015 Chevrolet SS uses a staggered tire setup rather than one size at all four corners. The front size is 245/40R19 and the rear size is 275/35R19, with both positions using radial construction on 19-inch wheels.
That means replacement starts with confirming which axle you are servicing. If the car still has its original-style wheel arrangement, the front and rear sizes should stay in their intended positions. Any owner working with aftermarket wheels, a square setup conversion, or suspension changes should verify actual wheel width and clearance before choosing tires.
What size rim does a 2015 Chevrolet SS use?
The 2015 Chevrolet SS uses 19-inch rims with both of its primary tire sizes. The 245/40R19 front tire and 275/35R19 rear tire are both built for a 19-inch wheel diameter, which keeps rim diameter consistent even though front and rear widths differ.
Rim diameter is only part of the fitment picture, so it is worth checking wheel width as well before buying replacements. Some 245/40R19 products call for an 8.0 to 9.5-inch rim, while some 275/35R19 products are intended for 9.0 to 11.0-inch rims. Matching both diameter and width helps preserve handling balance and proper tire shape.
Why does the 2015 Chevrolet SS have more than one tire size?
The 2015 Chevrolet SS has more than one tire size because it uses a staggered fitment, with 245/40R19 on the front and 275/35R19 on the rear. The front and rear tires are intentionally different widths even though both use the same 19-inch rim diameter.
For the buyer, that means tire selection is tied to axle position rather than trim variation. A staggered setup can affect rotation patterns, replacement planning, and wheel compatibility, so it is smart to confirm whether the car still retains its original front-and-rear arrangement. Cars with changed wheels or suspension should be measured rather than assumed to match stock fitment.
Choosing the Right Tire
What should I consider when choosing tires for a 2015 Chevrolet SS?
Start with the correct position-specific size: 245/40R19 for the front and 275/35R19 for the rear. From there, compare tire series, radial construction details, rim-width compatibility, weight, and any stated load information so the replacement matches the wheel and the way the car is driven.
The 2015 Chevrolet SS has a performance-oriented staggered setup, so keeping the front and rear relationship intact is usually the first priority. Buyers should also think about whether they want a more seasonal all-season style option or a more explicitly performance-focused series, while confirming that the actual wheel dimensions on the car still match the tire's intended range.
What brands offer tires for the 2015 Chevrolet SS?
Available tire choices for the 2015 Chevrolet SS include BFGoodrich and Nitto, depending on size and series. BFGoodrich appears in both the 245/40R19 front and 275/35R19 rear sizes, while Nitto is available in the 275/35R19 rear fitment.
Brand is only one part of the decision, so it helps to compare each option by size, tire series, and wheel-width compatibility rather than name alone. On this car, BFGoodrich gives broader coverage across both front and rear sizes, while the rear position adds another series choice through Nitto for owners comparing performance-oriented blackwall radials.
What tire series are available for the 2015 Chevrolet SS?
The 2015 Chevrolet SS has several performance-oriented tire series available in its primary sizes. BFGoodrich offers g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A, while the 275/35R19 rear size also includes the Nitto NT555 G2.
Those series give the buyer a useful way to compare options beyond size alone. Some owners may want to keep the same series front and rear where possible, while others may be replacing only one axle and need to match the correct size first. Wheel-width range, load details where stated, and the car's current use should guide the final choice.
Restoration & Appearance
Does correct tire fitment matter for a 2015 Chevrolet SS restoration?
Yes, correct tire fitment matters on a 2015 Chevrolet SS because the car uses a specific staggered arrangement with 245/40R19 in front and 275/35R19 in back. Keeping the intended front and rear sizing helps preserve the car's designed stance, wheel relationship, and overall visual balance.
A restoration-minded owner should also pay attention to sidewall presentation and wheel specifications, even though the available options here are blackwall radials rather than vintage-style collector tires. If exact originality is a concern, compare the car against Chevrolet literature, window-sticker documentation, or model-specific enthusiast references before choosing a replacement series.
How does tire selection affect the appearance of a 2015 Chevrolet SS?
Tire selection affects the appearance of a 2015 Chevrolet SS by shaping how the car sits on its 19-inch wheels and whether the front-to-rear stagger looks properly proportioned. The available fitments are blackwall radials, so the main visual differences come from maintaining the correct sizes and choosing a tire series that suits the car's character.
Appearance changes quickly when the staggered relationship is disturbed or when wheel widths no longer match the intended tire profile. A car with aftermarket wheels may look noticeably different even in the same nominal size, so it is worth checking actual wheel dimensions and overall presentation before replacing only one pair and leaving the rest untouched.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Chevrolet SS?
Yes, modifications can affect tire fitment on a 2015 Chevrolet SS even when the nominal tire sizes remain 245/40R19 in front and 275/35R19 in back. Changes to wheel width, offset, ride height, springs, or alignment can alter clearance at the fender, suspension, or steering components.
That is why modified cars should be checked as they sit, not assumed to match stock dimensions. A tire that works on an original 19-inch setup may not behave the same way on a wider aftermarket wheel or lowered suspension. Measuring wheel specs and inspecting clearance at full steering lock and suspension travel helps avoid expensive mistakes.
What should I inspect before driving a 2015 Chevrolet SS on new tires?
Before driving a 2015 Chevrolet SS on new tires, inspect tire pressure, wheel torque, valve stems, and the overall condition of the wheels themselves. It also helps to confirm that the front tires are 245/40R19 and the rear tires are 275/35R19 so the staggered setup has been installed in the correct positions.
A short initial drive should be followed by another visual check for rubbing, uneven seating, or any sign of contact near the inner fender or suspension. Cars that have been parked for long periods deserve extra attention to alignment, brake drag, and suspension wear, since fresh tires can reveal steering or handling issues that older worn tires may have masked.
How should tires on a 2015 Chevrolet SS be maintained?
Tires on a 2015 Chevrolet SS should be maintained with regular pressure checks, routine visual inspection, and periodic review of tread wear across both axles. Because the car uses different front and rear sizes, maintenance should account for the staggered setup rather than treating all four tires as interchangeable.
Watch for uneven wear, sidewall damage, punctures, bulges, or slow air loss, and inspect more often if the car sees spirited driving or long idle periods. Storage conditions matter too, since heat, sunlight, and extended sitting can age a tire before tread is worn out. Good maintenance starts with keeping each tire in the correct position and monitoring condition consistently.
