Tires were purchased in June of 08 -
I don't know how to figure the off set
Less than 1,000 miles, very EASY miles, that's when I had my tired 318 in the car.
Never stored the car on the tires, they have been stored on their side with cardboard between them to protect the raised white letters.
No burn outs, the 318 would not turn them over!
I don't know what W23 is, I have the fender tag and the broadcast sheet, I think these are the original rims.
part of my build sheet is ripped and missing, but, up on the top on the line marked Codes 4, under wheels it reads like this;
WHEEL
