Every car is different....

I have 245/40/18's on 18x8 Foose Legends w/5.0" BS on the front of my '67 and they would rub if I didn't have adjustable steering stops on my SpeedTech LCA's. 235 would probably be safer up front. I also have the 275/40/18's on 18x9 w/5.25" BS and they are very close but don't rub in the rear. In theory 275's are 20mm wider than 255's which translates to .79 inches wider.



FWIW I have the Hotchkis 2" lowering springs in the front and 1.5" springs in the rear.

Thanks for the input. Sounds like you have exactly what I was planning to go with. Do you think 4.75 bs on the fronts (as recommended above) would have solved the rubbing issue you have?

Quite possibly, just as long as it doesn't push the wheel to far outward. I haven't really checked to see how much extra room is on the outside of the wheel. The only time I had rubbing was backing out, or turning into a driveway with a bit of a lip.
