The 2013 SRT Viper marked the return of Dodge’s modern American supercar under the SRT banner, carrying forward the Viper’s long-hood, big-engine, high-grip character in a more refined but still unmistakably aggressive package. Tire selection on this car is tightly tied to that purpose-built layout, with a 295/30R18 radial up front and a 355/30R19 radial at the rear. That staggered setup is central to the car’s stance and handling balance, so the decision is less about finding a single universal size and more about matching the correct front and rear fitment. Owners should verify wheel size and any modifications before changing brands, tread patterns, or overall tire type.
Which Tire Size Is Right for The 2013 SRT Viper
The 2013 SRT Viper uses two primary tire sizes, and they are position-specific rather than interchangeable. A 295/30R18 radial is used at the front, while a 355/30R19 radial is used at the rear, so the first step is confirming both wheel diameter and whether the tire is intended for the front or rear of the car. Once that is established, the real decision becomes choosing the right tire within each size for the car’s current wheel and suspension setup.
295/30R18 is a modern metric radial size in which 295 identifies the nominal section width in millimeters, 30 is the aspect ratio, R designates radial construction, and 18 is the wheel diameter in inches. On the 2013 SRT Viper, this size is used at the front, where steering response, clearance, and wheel compatibility all matter. Its low-profile radial format reflects the Viper’s contemporary high-performance tire layout rather than a vintage sizing system. Choosing this size means matching the front wheel diameter correctly and confirming that the car still retains the intended front-end fitment.
355/30R19 is a modern metric radial size that uses a very wide 355-millimeter section width, a 30-series profile, radial construction, and a 19-inch wheel diameter. On the 2013 SRT Viper, this size belongs at the rear, where the staggered setup supports the car’s traction-oriented layout and visual proportions. This is not a substitute for the front tire size, even though both are modern radial formats. Selecting this size calls for careful rear wheel confirmation, especially on cars with aftermarket wheels, suspension changes, or any previous fitment changes.
Fitment is consistent across the covered 2013 SRT Viper Base and GTS configurations, but it remains a staggered front-and-rear setup. Checking the exact position still matters, because the front and rear of the car do not use the same tire size or rim diameter.

2013 SRT Viper Base Front
The 2013 SRT Viper Base Front uses the smaller front-position radial fitment in the Viper’s staggered setup. Tire selection here centers on preserving the correct front wheel diameter and maintaining proper steering and clearance relationships.
The 2013 SRT Viper Base Rear uses the wider rear-position radial size that completes the car’s staggered layout. Choosing a rear tire means confirming the 19-inch wheel setup and avoiding any attempt to treat the rear size as interchangeable with the front.
The 2013 SRT Viper GTS Front uses the same front radial tire size as the Base model. That keeps front fitment straightforward, but buyers should still confirm wheel specifications and any modifications before changing tire models.
The 2013 SRT Viper GTS Rear uses the same rear radial tire size as the Base model. The main consideration is preserving the intended rear fitment by matching the correct wheel diameter and checking clearance on cars that no longer wear their original-style wheel 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.
Frequently Asked Questions
These FAQs focus on the 2013 SRT Viper’s staggered tire sizes, front-versus-rear rim fitment, product-selection priorities, and the practical checks that matter before road use on a modern high-performance collector car.
Tire Size & Fitment
What tire size fits a 2013 SRT Viper?
The 2013 SRT Viper uses a staggered radial setup with 295/30R18 tires at the front and 355/30R19 tires at the rear. Both the Base and GTS use that same front-and-rear size arrangement, so the fitment question is really about tire position rather than trim level.
That means there is no single all-around tire size for the car. Front and rear tires use different widths and different wheel diameters, so the first thing to confirm is whether the tire being replaced belongs on the front axle or the rear. Any aftermarket wheel or suspension change should also be checked before selecting a replacement.
What size rim does a 2013 SRT Viper use?
The 2013 SRT Viper uses two rim diameters as part of its staggered setup: an 18-inch front rim with the 295/30R18 tire and a 19-inch rear rim with the 355/30R19 tire. That front-and-rear difference applies across both the Base and GTS configurations.
Rim diameter is one of the most important checks on this car because the front and rear wheel sizes are not the same. A buyer replacing tires should confirm both the position on the car and the actual wheel installed, especially if the Viper has been modified or if a previous owner changed the wheels from the original-style staggered arrangement.
Do all 2013 SRT Viper sub-models use the same tire size?
Yes, the covered 2013 SRT Viper Base and GTS models share the same staggered tire fitment. Each uses 295/30R18 at the front and 355/30R19 at the rear, so the difference is not between sub-models but between front and rear positions on the vehicle.
That makes sub-model identification simpler, but position still matters every time a tire is replaced. A front tire should be matched to the front wheel and a rear tire should be matched to the rear wheel, with no assumption that the two sizes can be swapped. Wheel changes, alignment settings, and suspension modifications can still affect fitment.
Choosing the Right Tire
What should I consider when choosing tires for a 2013 SRT Viper?
Start with the correct staggered fitment: 295/30R18 for the front and 355/30R19 for the rear. Because the 2013 SRT Viper is built around two different tire widths and two different wheel diameters, the most important selection step is matching the right size to the right position on the car.
After size, focus on the actual wheel setup and how the car is used. A Viper kept on its original-style wheel dimensions calls for a different level of checking than one with aftermarket wheels or altered suspension. Replacing tires in matched front-and-rear sets can also help preserve the intended stance and fitment balance of the staggered layout.
How do I choose between the available 295/30R18 and 355/30R19 tires for a 2013 SRT Viper?
The first step is not choosing between the two sizes, but assigning each size to its proper axle. The 295/30R18 belongs at the front and the 355/30R19 belongs at the rear, so each tire should be evaluated as part of the Viper’s overall staggered setup rather than as a universal replacement.
Selection becomes easier once position is confirmed. Compare the tire against the wheel already on the car, check that front and rear fitments remain consistent side to side, and account for any suspension or wheel changes. Keeping the intended front-to-rear size relationship intact is especially important on a car with such a wide rear tire footprint.
What rim-fitment details should I compare when choosing 2013 SRT Viper tires?
The key rim-fitment detail on a 2013 SRT Viper is wheel diameter by position: 18 inches at the front and 19 inches at the rear. Since the car uses 295/30R18 front tires and 355/30R19 rear tires, the wheel and tire sizes need to stay matched to their intended axle positions.
It also helps to confirm the actual wheels installed on the car before ordering replacement tires. A Viper with aftermarket wheels may have different widths or offsets than expected, and those changes can affect clearance and overall fitment. Taking a moment to verify the front and rear wheel setup can prevent ordering the right size for the wrong wheel.
Restoration & Appearance
Does correct tire fitment matter for a 2013 SRT Viper restoration or collector-grade presentation?
Yes, correct tire fitment matters because the 2013 SRT Viper’s appearance is closely tied to its staggered layout. The combination of a 295/30R18 front tire and a 355/30R19 rear tire helps define the car’s proportions, so an incorrect width or wheel diameter can change both stance and overall visual balance.
Collectors and careful owners usually want the car to look coherent as well as fit correctly. Keeping the proper front-versus-rear relationship is often more important than chasing a cosmetic shortcut. If exact originality matters beyond size and construction, vehicle-specific reference material and marque knowledge remain useful before making a final appearance-driven tire decision.
How does tire sizing affect the appearance of a restored or well-kept 2013 SRT Viper?
Tire sizing has a strong visual effect on a 2013 SRT Viper because the car was styled around a very wide rear tire and a lower, narrower front tire. The 295/30R18 front and 355/30R19 rear combination contributes to the Viper’s nose-to-tail proportion and its planted rear stance.
Changing that relationship can alter more than just fitment. A mismatched front or rear size may affect how the wheel openings are filled and how the car sits visually from different angles. Owners aiming for a clean collector presentation usually benefit from keeping the intended staggered sizing concept intact unless the entire wheel-and-tire package has been thoughtfully reworked.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 SRT Viper?
Yes, modifications can affect tire fitment on a 2013 SRT Viper even when the tire sizes appear correct on paper. Aftermarket wheels, altered offsets, suspension changes, lowering, or body modifications can change clearance at the fenders, suspension components, or steering range, especially on a car with a wide staggered setup.
That is why the installed wheel-and-suspension package should be checked before replacing tires. A front 295/30R18 and rear 355/30R19 may be the intended sizes, but the car still needs enough real-world clearance in motion and at full steering input. Modified cars deserve a closer look than stock-configured examples before any new tire is mounted.
What should I inspect before driving a 2013 SRT Viper on new tires?
Before driving a 2013 SRT Viper on new tires, inspect basic installation and condition points such as proper tire position, correct air pressure, secure mounting, and visible clearance around the front and rear wheel openings. It is also worth checking for uneven wear patterns or signs that the previous tires may have been rubbing.
A short, careful road check can confirm that the car tracks cleanly and that nothing contacts under steering or suspension movement. Since the Viper uses different front and rear sizes, each axle should be reviewed on its own rather than treated as a single generic fitment. Any vibration, pull, or rubbing deserves attention before regular road use.
How should 295/30R18 and 355/30R19 tires on a collector 2013 SRT Viper be maintained?
Tires on a collector-driven 2013 SRT Viper should be maintained with regular pressure checks, visual inspections, and routine attention to age and condition. The front 295/30R18 and rear 355/30R19 tires should be examined for cracking, cuts, bulges, punctures, uneven wear, or slow air loss, especially if the car is driven infrequently.
Storage conditions matter on low-use performance cars. Keeping the Viper away from prolonged sun, excess heat, moisture, and ozone sources can help protect tire condition between drives. It also helps to inspect the tires before longer outings rather than assuming low mileage means low risk, since age and storage can matter as much as tread depth.
