The 2014 SRT Viper belongs to the modern return of one of America’s most uncompromising performance cars, with huge power, a long hood, and a chassis that expects serious tire under it. On a car like this, tire fitment is not a cosmetic afterthought but a core part of how the Viper sits, steers, and puts power to the pavement. The 2014 SRT Viper uses staggered radial sizing, with 295/30R18 up front and 355/30R19 at the rear. That makes the real decision less about choosing between multiple overall fitment paths and more about matching the correct front and rear sizes to the car’s intended road use and wheel setup.
Which Tire Size Is Right for The 2014 SRT Viper
The 2014 SRT Viper uses two primary tire sizes, and they serve different positions on the car rather than different trim-level alternatives. The first step is confirming whether you are selecting a front or rear tire, because the Viper uses a staggered radial setup with different rim diameters: 18 inches in front and 19 inches in back. Once that is clear, the decision becomes choosing the right tire within the correct position-specific size.
295/30R18 is a metric radial size in which 295 refers to nominal section width in millimeters, 30 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2014 SRT Viper, this is the front tire size, so it plays a direct role in steering response, turn-in feel, and front-end clearance. Its relatively short sidewall is consistent with the Viper’s aggressive performance-oriented setup. Choosing this size means confirming the front wheel position and keeping the front tire matched to the car’s staggered layout rather than treating it as a universal four-corner fitment.
355/30R19 is a metric radial size where 355 indicates nominal section width in millimeters, 30 is the aspect ratio, R denotes radial construction, and 19 identifies the wheel diameter in inches. On the 2014 SRT Viper, this is the rear tire size and is central to the car’s wide-footprint, high-power rear-drive character. The combination of a very broad section width and short sidewall makes rear wheel confirmation especially important. This size should be evaluated as the dedicated rear fitment, with attention to maintaining the intended staggered relationship between front and rear tire sizing.
Fitment is consistent across the covered 2014 SRT Viper Base, GTS, and TA configurations, but the car still uses different sizes at the front and rear. Checking the exact position matters most, since selecting the wrong end of the staggered setup is a more common mistake than choosing the wrong sub-model.

2014 SRT Viper Base Front
The 2014 SRT Viper Base Front uses the 295/30R18 radial size. Tire selection here centers on getting the correct front-position fitment and maintaining the intended staggered balance with the larger rear tire.
The 2014 SRT Viper Base Rear uses the 355/30R19 radial size. That makes rear tire selection a matter of confirming the 19-inch rear wheel setup and preserving the car’s dedicated front-to-rear size relationship.
The 2014 SRT Viper GTS Front uses the same 295/30R18 radial tire size as the other covered front positions. Choosing within this fitment means verifying the front wheel location first, then matching the tire to the Viper’s staggered layout.
The 2014 SRT Viper GTS Rear uses the 355/30R19 radial size. Rear tire choice should stay focused on the correct back-wheel fitment, since this size is not interchangeable with the front of the car.
The 2014 SRT Viper TA Front uses 295/30R18 in radial construction. Selection at this position should keep the front-specific sizing intact and avoid mixing it with rear dimensions simply because both belong to the same vehicle.
The 2014 SRT Viper TA Rear uses the 355/30R19 radial size. This rear fitment is a key part of the Viper’s staggered setup, so wheel position and proper rear-size matching deserve attention before replacement.
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.
Frequently Asked Questions
Owners of a 2014 SRT Viper usually need clear answers on staggered front and rear sizing, rim diameters, sub-model consistency, and the checks that matter before road use. The questions below focus on exact fitment, tire selection priorities, and maintenance for a high-performance Viper setup.
Tire Size & Fitment
What tire size fits a 2014 SRT Viper?
The 2014 SRT Viper uses a staggered tire setup with 295/30R18 on the front and 355/30R19 on the rear. Both sizes are radial, and they are position-specific rather than interchangeable alternatives for the same wheel location.
That means the first fitment step is identifying whether the tire is for the front or rear of the car. A Viper owner should also confirm the actual wheel setup on the car, especially if wheels have ever been changed, because the front uses an 18-inch rim and the rear uses a 19-inch rim.
What size rim does a 2014 SRT Viper use?
The 2014 SRT Viper uses two rim diameters as part of its staggered layout: 18 inches for the front tire size and 19 inches for the rear tire size. The 295/30R18 front tire fits the 18-inch front wheel position, while the 355/30R19 rear tire fits the 19-inch rear wheel position.
Rim diameter confirmation is critical on a staggered performance car because front and rear tires are not meant to swap positions. Checking the wheel itself before ordering helps avoid a mismatch, particularly on cars that may have seen aftermarket wheel changes or previous replacement tires.
Do all 2014 SRT Viper sub-models use the same tire size?
The covered 2014 SRT Viper Base, GTS, and TA configurations share the same position-based sizing pattern. Each uses 295/30R18 at the front and 355/30R19 at the rear, so the fitment stays consistent across these sub-models.
Even with that consistency, tire selection still depends on wheel position because the Viper’s front and rear sizes are different by design. A buyer should verify whether the replacement is for the front or rear axle first, then confirm that the car still retains its intended staggered wheel arrangement.
Choosing the Right Tire
What should I consider when choosing a 295/30R18 and 355/30R19 tire set for a 2014 SRT Viper?
The main priorities are keeping the correct front and rear sizes, matching the tire to the proper wheel position, and staying with the Viper’s radial staggered layout. Because 295/30R18 and 355/30R19 serve different jobs on the car, they should be chosen as a coordinated front-and-rear fitment rather than as isolated sizes.
Wheel diameter is only the starting point on a Viper. It also helps to confirm that the car still has its intended wheel setup, that suspension height has not changed in a way that affects clearance, and that the replacement tires suit the kind of road use the car will actually see.
How do I choose between the available 2014 SRT Viper tire positions when ordering replacements?
The key distinction is not between trim levels but between front and rear placement. The 2014 SRT Viper uses 295/30R18 for the front and 355/30R19 for the rear, so ordering starts with identifying the exact axle position that needs replacement.
That matters because a staggered performance car depends on each end of the vehicle carrying the correct size. Replacing only one end should still involve checking the condition and age of the tires on the other end, since uneven wear or mismatched setups can complicate how the car feels on the road.
What rim-fitment details should I compare when choosing tires for a 2014 SRT Viper?
The most important rim-fitment detail is matching each tire to the correct rim diameter and wheel position. The 2014 SRT Viper uses an 18-inch front fitment with 295/30R18 and a 19-inch rear fitment with 355/30R19, so front and rear wheels should be confirmed separately.
It is also wise to inspect the actual wheels on the car for changes from original-style sizing or for any setup that may alter clearance. On a wide, low-profile Viper fitment, even a seemingly small wheel change can affect how confidently the correct tire size can be selected.
Restoration & Appearance
Does correct tire fitment matter for a 2014 SRT Viper restoration?
Yes. Even though the 2014 SRT Viper is a modern performance car rather than a vintage restoration candidate in the traditional sense, correct fitment still matters for stance, wheel-to-body proportion, and preserving the car’s intended staggered presentation. The proper relationship is 295/30R18 in front and 355/30R19 in the rear.
Appearance on a Viper is closely tied to size accuracy because the car’s visual character depends on its very wide rear footprint and low-profile setup. Anyone pursuing a faithful presentation should confirm the exact wheel arrangement on the car before changing sizes, especially if prior owners may have modified it.
How does tire sizing affect the appearance of a restored or preserved 2014 SRT Viper?
Tire sizing strongly influences how a 2014 SRT Viper sits and looks because the car relies on a pronounced staggered setup. The 295/30R18 front and 355/30R19 rear combination gives the car its intended visual balance, with a noticeably broader rear presence than the front.
Changing that relationship can alter the car’s overall presentation even before it affects road behavior. Owners focused on preserving the Viper’s original-style stance should check both wheel position and actual mounted size carefully, rather than assuming any low-profile performance tire will maintain the same look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 SRT Viper?
Yes. A 2014 SRT Viper is especially sensitive to wheel, suspension, and ride-height changes because it uses a staggered setup with very wide rear tires and low-profile sidewalls. Even when the nominal tire size stays the same, modifications can change available clearance at the fender, suspension, or steering components.
An owner should check the actual wheels on the car, confirm front and rear diameters separately, and inspect for any lowering or aftermarket suspension parts before replacing tires. On a Viper, small setup changes can have a larger effect than they would on a more forgiving street car.
What should I inspect before driving a 2014 SRT Viper on new tires?
Start with basic condition checks around the whole wheel-and-tire package: proper air pressure, secure mounting, valve condition, and any signs of rubbing once the car is on the ground. It also helps to inspect the wheels for damage and make sure the front 295/30R18 and rear 355/30R19 positions have not been mixed up.
A short, careful shakedown drive is smart before putting real miles on the car. During that first outing, pay attention to steering feel, vibration, unusual noise, and clearance under turning or suspension movement so any setup issue can be addressed before harder use.
What should I check before a longer drive in a 2014 SRT Viper?
Before a longer drive, confirm that both tire sizes are correctly installed by position, inspect tread and sidewalls for cuts or damage, and verify that pressures are set consistently. On a low-profile, staggered car like the 2014 SRT Viper, a quick visual check can catch problems that are easy to miss when the car is driven infrequently.
It is also wise to look for signs of age, air loss, or contact marks near the inner fender and suspension area. A Viper that has sat for extended periods deserves extra attention, since collector-style storage and limited use can affect tire condition even when tread wear appears minimal.
