ok i think im going to pick up a new set of rims for my 82 ponty grand prix.

do new rims need to be balanced?

the rear rims im looking at are 8 inchs wide and the tires i want to run on the rear till i get some new tires are 215/65R15, suggested that 225 is the smallest tire for the 8 inch wide tire, is it fine to run the 215 or will somthing bad happen?

for backspacing and offset how do these look?

Front Rims:15 X 7, Back Spacing 3.75 INCHES, Offset -6MM,-.250 INCHES

Rear rims:15 X 8, Back Spacing 3.75 INCHES, Offset -19MM,-.750 INCHES

i want the rear rims to stick out farther since the wheel wells are pretty wide.

the rims i got right now are 15x7 with 4 3/8 inch backspacing and the front rims rub on the upper a-arm when the wheels are turned full(metal shavings all over!) and the rear tires have about .25 inch of clearnce to the frame with 215/65R15 tires! not to good.

Tires and wheels are balanced as a unit.

It might not be a bad idea to have the rims put on the balancer, that way you will know if you have bad rim.

alright thanks

what do u guys think about the 215 tire on the 8 inch rim? should it be fine?

I would say wait till you get the bigger tires..Might be a real problem getting the tire to seal on the rim if its to small.
