2014 SRT marked a brief but memorable moment when the Viper stood as its own performance make, separate from Dodge and focused on one of America’s most uncompromising modern supercars. The 2014 SRT Viper carried that identity with enormous grip, dramatic proportions, and a tire package built around serious front-to-rear stagger rather than one universal size. Across the 2014 SRT range, one model uses two different radial sizes, with an 18-inch front fitment and a 19-inch rear fitment that work together as a matched setup. Before choosing a tire for 2014 SRT, confirm that you are matching the correct position on the car, since front and rear sizes are different.
Which Tire Size Is Right for Your 2014 SRT
Two tire sizes are used on 2014 SRT vehicles, and both belong to the Viper rather than being interchangeable across different models. The real decision starts with confirming position first, because the front and rear tires use different rim diameters and are part of a staggered radial setup. Understanding that distinction before choosing a product saves time and ensures the right match.
Year(s): 2014|Fit(s): Viper|Construction: Radial|Rim: 18-in rim
295/30R18 is a metric radial size with a 295-millimeter section width, a 30-series aspect ratio, and an 18-inch rim diameter. It is the front size for the 2014 SRT Viper, not a universal fitment across the year and make. This size uses radial construction, which suits the Viper’s modern chassis and high-speed road manners.
Year(s): 2014|Fit(s): Viper|Construction: Radial|Rim: 19-in rim
355/30R19 is a metric radial size with a 355-millimeter section width, a 30-series aspect ratio, and a 19-inch rim diameter. It is specific to the rear of the 2014 SRT Viper and pairs with the smaller front size as part of the car’s factory-style stagger. Buyers should treat this as the companion rear fitment for maintaining the Viper’s intended stance, traction balance, and overall look.
One model is covered for 2014 SRT. Tire sizing does not vary by model, but it does vary by axle position, so identifying the Viper alone is only the first step and front versus rear size still matters. Select the model below for model-specific fitment history and products.
2014 SRT Viper
The 2014 SRT Viper carried forward the long-hood, V10-powered formula that made the nameplate one of the most distinctive American performance cars of its era. Its tire package reflects that mission with a true staggered setup, using an 18-inch front rim and a 19-inch rear rim rather than the same size at all four corners. That difference is central to preserving the car’s intended appearance and handling balance.
These answers focus on the 2014 SRT Viper’s staggered front-and-rear sizing, how to decode modern metric radial sizes, and what to check for fitment, road use, and storage on a low-production performance car.
Size Basics & Fitment
What tire sizes fit 2014 SRT vehicles?
2014 SRT vehicles use two tire sizes, both on the Viper: 295/30R18 at the front and 355/30R19 at the rear. Both are radial sizes, and they do not share the same rim diameter, so they are not interchangeable from one axle to the other. The front tire mounts on an 18-inch wheel, while the rear tire mounts on a 19-inch wheel.
That means a 2014 SRT owner needs to confirm more than just year and model before choosing tires. Front and rear position matters because the Viper uses a purpose-built staggered setup to support its stance and traction balance. If you are replacing one pair only, verify the actual tire size on the car and make sure the new tires match the correct axle.
What does 295/30R18 mean on a 2014 SRT tire?
On a 2014 SRT Viper, 295/30R18 identifies a metric radial tire. The 295 is the nominal section width in millimeters, 30 is the aspect ratio, meaning the sidewall height is 30 percent of the section width, R indicates radial construction, and 18 is the wheel diameter in inches. On the Viper, this size serves the front position.
That decoding matters because modern performance tires use the size code to describe both dimensions and construction in a compact format. A 295/30R18 is not just wide; it is also low-profile and built for an 18-inch wheel. If your 2014 SRT needs front tires, matching that full code is the safest starting point before comparing tread designs or brand options.
What does 355/30R19 mean on a 2014 SRT tire?
On a 2014 SRT Viper, 355/30R19 is a metric radial tire size with a 355-millimeter nominal section width, a 30-series profile, radial construction, and a 19-inch rim diameter. It is the rear tire size in the Viper’s staggered setup. The code tells you immediately that it is both wider and mounted on a larger wheel than the front tire.
For a 2014 SRT owner, that means the rear tire should never be treated as a simple alternate to the front size. The larger width and different rim diameter are part of the car’s intended rear traction package. If you are replacing rear tires, confirm that the wheel on the car is the correct 19-inch rear wheel and not a non-original setup.
Buying the Right Tire
How should I choose front and rear tires for a 2014 SRT Viper?
A 2014 SRT Viper needs the correct tire size at each end of the car: 295/30R18 in front and 355/30R19 in the rear. Because both sizes are radial and serve different positions, the main choice is not between old and new construction styles but between the correct matched fitment for the axle you are servicing. Keeping the intended stagger is central to how the car was designed to sit and drive.
Most buyers should begin by deciding whether they are replacing a single damaged tire, a front pair, a rear pair, or all four. Then confirm the actual wheel diameters on the car, since modified Vipers can wear non-original wheel packages. Staying with the correct front and rear sizing is the best way to preserve proportional appearance and avoid introducing avoidable fitment problems.
Fitting & Setup
Can the original 2014 SRT wheels be used with both tire sizes?
A 2014 SRT Viper uses two different original wheel diameters, so each tire size belongs to its own wheel position rather than both sizes fitting the same wheel. The 295/30R18 fits the front 18-inch wheel, and the 355/30R19 fits the rear 19-inch wheel. That means the original wheels can be used with the correct corresponding size, not interchangeably across both axles.
This is especially important on a car like the Viper, where the staggered package is a fundamental part of the overall setup. Before mounting replacement tires, verify the actual wheel diameters and widths on the car, especially if it has seen aftermarket wheel changes. A front tire on a rear wheel, or vice versa, is not a matter of preference; it is simply the wrong fit.
Maintenance, Storage & Longevity
How should I store a 2014 SRT when the tires are fitted?
A 2014 SRT Viper should be stored in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment that can age rubber prematurely. Keep the tires clean, set pressures correctly before storage, and move the car periodically if it will sit for long stretches. Radial tires resist flat-spotting better than older bias-ply designs, but long static storage still is not ideal.
If the car will remain parked for months, many collectors use tire cradles or stands to reduce stress on the carcass and suspension. That is especially worthwhile on a high-value performance car with very wide rear tires. A breathable indoor cover and a quick monthly pressure check help preserve the tires as much as the body and interior.
How long do tires on a 2014 SRT typically last?
Tire life on a 2014 SRT Viper should be judged by age, condition, and storage history as much as by tread depth. A common collector-car standard is to begin close inspection at around five to seven years and to treat ten years as a strong replacement threshold even if the tread still looks usable. The DOT date code on each tire is the starting point for that evaluation.
Mileage alone can be misleading on an enthusiast car that may be driven sparingly but aggressively. Heat cycles, sun exposure, and long periods of storage all affect the rubber over time. If your 2014 SRT still wears older tires with ample tread, age-related hardening can still reduce grip and confidence well before the tread is gone.
How often should tires on a 2014 SRT be inspected?
Tires on a 2014 SRT should be checked before every drive and again before any longer outing or highway trip. Look for cracking, punctures, bulges, unusual shoulder wear, embedded debris, and any sign that one tire is losing pressure faster than the others. On a staggered performance car, uneven wear can also point to alignment or suspension issues rather than tire problems alone.
A quick inspection is especially worthwhile because the Viper’s low-profile tires can hide damage until the car is moving at speed. Check cold pressures, inspect the valve stems, and look at the inside sidewall if the car has recently hit a pothole or curb. Catching a problem in the garage is far better than discovering it once the car is fully loaded and hot.
Safety & Road Use
Are 2014 SRT tires safe for highway driving?
2014 SRT Viper tires use modern radial sizing, which is well suited to normal highway driving when the tires are in good condition, correctly sized for the front or rear position, and properly inflated. Safety depends heavily on the age and condition of the specific tire, along with the condition of the car itself. On a high-performance car, suspension condition, alignment, and brake health matter just as much as tread depth.
For real-world use, the key is to treat the Viper as a complete system rather than focusing on the tire alone. A fresh set of properly matched front and rear tires can only do their job if the wheels are true and the chassis is sorted. Before sustained highway use, verify pressures cold and inspect every tire closely, including the spare if the car carries one.
What inflation pressure should I use for 2014 SRT tires?
Inflation pressure for 2014 SRT tires should follow the vehicle manufacturer’s recommendation for the Viper and the tire manufacturer’s own operating limits for the exact product you choose. Front and rear pressures are often different on a staggered high-performance car, so one number should never be assumed for both sizes. The tire sidewall’s maximum pressure marking is not automatically the correct everyday running pressure.
Start with the factory placard or owner’s manual, then confirm that the tire you select is being used within its approved pressure range. Check pressures cold, not after the car has been driven. If the car has aftermarket wheels, alignment changes, or non-stock suspension settings, a knowledgeable Viper specialist can help fine-tune pressure targets without guessing.
What should I check before taking a 2014 SRT on a longer drive?
Before a longer drive in a 2014 SRT Viper, inspect each tire for cuts, sidewall damage, bulges, uneven wear, and proper cold inflation. Confirm that the front tires are 295/30R18 and the rear tires are 355/30R19, and look over the valve stems for age or damage. On a car with very wide rear tires, it is also smart to inspect inner sidewalls and wheel lips closely after any recent road impact.
Tires are only one part of the pre-drive routine on a modern collectible performance car. Check fluid levels, brakes, battery condition, lights, and the torque of the wheel fasteners to the manufacturer’s specification. If the car has been stored for a while, a short local shakedown drive before a longer trip can reveal vibration, pull, or pressure-loss issues before they become roadside problems.
