Hi there, new member here! I recently picked up an 03 GT with a 5 speed that I'm really enjoying so far. I just have a question about tire size (apologies if this has been asked a million times before, I tried searching and didn't really see anything). From what I can find online the stock tires on the car would've been 245/45R17s, but the previous owner put on 225/50R17s in both front and rear. The speedometer is off by about 10 MPH and I'm wondering if that might be why? I was told that the car still had original gear ratios. Would I need to get the speedo recalibrated regardless or would putting stock size tires back on correct that?
Thanks!
Thanks!
