Reply to "How big a wheel tyre combo can I put on a std body pantera ?"

315/25R20?

No tires in that size come up in a Tire Rack search. 305/25R20 and 325/25R20 are available, the 325's are what I installed on 6018. A 10" wheel is too narrow. The wheel width specs for the 305/25 tire are 10.5" to 11.5". The wheel width specs for the 325/25 tire are 11.5" to 12.5".

FYI, the 325/25R20 tire has the same revs per mile rating as the oem tires, which maintains the accuracy of the speedo, and the stock gearing.

The 235/30R20 you propose for the front of the car is too large in outside diameter, 25.7". The stock tire in front was 25", the larger tire will look wrong in the wheel well. My car has 18" wheels in front, which dramatically emphasizes the fact that the front tires are smaller than the rears.

In designing the wheel and tire combination I worked with a gentleman who has specified and assembled numerous wheel and tire packages for Panteras, he is a former Kinesis employee. I had intended to use a 235/35R18 front tire, but he advised me to run the slightly larger 245/35R18. He said the Pantera needs every bit of rubber up front to help it stick in the corners.
