225/70VR15 Michelin XWX
225/70VR15 Michelin XWX is an unusual tyre size. There are few cars that fitted this tyre; the rear of Ferrari 512, Berlinetta Boxer (BB) and some Ferrari Daytona have wider 9" rims to fit this tyre. Though the recommended rim size for these tyres is between 6" and 8" the Ferrari 512 BB left the factory with these tyres fitted.
The Aston Martin V8 fitted the size 225/70R15. The Michelin XWX is presently the only tyre with a W (170mph) speed rating in this size and would be the best tyre you could fit.
