Detailed tire and wheel breakdown for the 1999 Dodge Viper
Tire geometry â 275/40R17
The 275/40R17 fitted to the 1999 Dodge Viper has a section width of 275mm and an aspect ratio of 40%, mounted on a 17-inch rim. That gives a sidewall height of 110.0mm (4.33") and an overall outside diameter of 651.8mm (25.66"). At highway speed this tire completes roughly 488 revolutions per kilometre, which is what your speedometer and odometer are calibrated against.
Plus-sizing window
If you want to upsize wheels on the 1999 Dodge Viper while keeping the speedometer accurate, target a 285/34R18 (plus-one). For a softer ride or winter setup, a 265/46R16 (minus-one) keeps the overall diameter within Âą3% of stock, which is the industry tolerance for ABS and stability control to stay calibrated.
Wheel fitment specs
The 1999 Dodge Viper uses a 6x114.3 bolt pattern with a 71.5mm hub bore. Safe rim width range for the OEM tire is 9.5J â 10.5J, and offsets in the ET45 â ET55 window will clear suspension and fender without rubbing on most setups.
Staggered setup notes
The 1999 Dodge Viper ships staggered: 275/40R17 up front and 335/35R17 on the rear. That is a 335mm vs 275mm width difference â do not rotate front-to-rear, and replace tires in axle pairs to keep ABS and traction control balanced.
Tire pressure guidance
Manufacturer-recommended cold tire pressure for the 1999 Dodge Viper is printed on the driver-side door jamb sticker â always defer to that value, not to the maximum pressure printed on the tire sidewall. Check pressure monthly and before long trips; under-inflation by 20% can reduce tread life by 25%.
