Thank you gents.
The rims are American Racing Salt Flats and are 17 ". Now Mr Rich Anderson from Shell Valley came over this month to see the car and advised us that you can go for at least an 8" wide tyre at the rear, if you want to go traditional then 8 X 15 is the way to go. As the front we are runnin 6 X17 so that it doesnt stick out. But again Shell Valley could make other suggestions.
Our tyres are : Front 225-45-R17 and rear 255-45-R17
