That tire size is fine ....... it is the choice of wheels I would worry about. Positive offset wheels are for modern front wheel drive cars (mostly). These old cars tended to use a zero offset or negative offset. The best thing you can do is measure your car and find out how much room you have between the face of the drum and the leaf spring. Then find out what the backspace is for those rims you want and figure extra room for the tire which bulges out even further than the rim edge. Hope this helps .............
I ran some huge 15 inch tires on the front of my 70 that come close to the demonsions of the 17's you mentioned. Not knowing what the backspacing is on the rim you are using, mine slighly rubbed the fender support rods at full turn. But, I lived with it.
Okay yes this has really helped, thank you all, does anyone know the absolute widest tires i can run on the car front and back? Im ginna try for maybe a 15x7 in rin, hopefully with zero offset. ?
Do some poking around on the sub forum that is just for tire and wheel questions. Lots of posts there. Lots to read. http://www.maverick.to/mmb/forumdisplay.php?f=39 I have found that what fits on one car may not fit on another - when you get into the upper end of sizes that is.
