18" wheel help?

tw0scoops · 10-11-2005, 03:55 PM

I have a 2005 Mustang GT. And I want to get some 18: wheels. Preferably the 18" deepdish bullits. My question is, do I need to retune the cars computer if I slap some BF Goodrich G-Force T/A 255/45/18 wheels on there?

It all depends on how tall your stock wheels and tires are and how much the new wheels and tires are.I went from 17's too 18's and there was little to no difference in the speedometer.My hieght of the 18's was almost the same as my 17's though.

255/45/18 is the perfect height for a 18x9 on an 05. No need to retune at all.
