Detailed tire and wheel breakdown for the 1964 Shelby Cobra
Tire geometry â 235/60R15
The 235/60R15 fitted to the 1964 Shelby Cobra has a section width of 235mm and an aspect ratio of 60%, mounted on a 15-inch rim. That gives a sidewall height of 141.0mm (5.55") and an overall outside diameter of 663.0mm (26.10"). At highway speed this tire completes roughly 480 revolutions per kilometre, which is what your speedometer and odometer are calibrated against.
Plus-sizing window
If you want to upsize wheels on the 1964 Shelby Cobra while keeping the speedometer accurate, target a 245/52R16 (plus-one). For a softer ride or winter setup, a 225/68R14 (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 1964 Shelby Cobra uses a Center Lock bolt pattern with a 0.0mm hub bore. Safe rim width range for the OEM tire is 7.0J â 8.0J, and offsets in the ET-5 â ET5 window will clear suspension and fender without rubbing on most setups.
Staggered setup notes
The 1964 Shelby Cobra ships staggered: 235/60R15 up front and 295/50R15 on the rear. That is a 295mm vs 235mm 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 1964 Shelby Cobra 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%.
