I was wondering if these tires are going to fit or if I need to go smaller.

Tire Specs:
Bridgestone RE11
205/50R15
Section Width: 8.4"
Tread Width: 7.6"
Overall Diameter: 23.1"

Wheel Specs:
Unknown Wheel
15x7"
4x110
Measured a +33 Offset

My car is an 84 GS, stock suspension but I may be throwing on some RB springs when I do my brakes next week. Do you think these will fit or will they be rubbing the springs?

 

i think your going to be on the springs.
i am running a 15x7 with a +17 offset with 225/45 tires and there is maybe 1/8" clearance

 

I run 205/40r17's on mine. I suggest mounting "1" and trying in all positions at the tire shop.

 

Yeah I was just a little worried about tread width, the RE11s are huge for 205/50R15 tires.
