??? about 315s and lowered height
The most body shop experience I've got is from using channel locks to pull in my fender tabs thanks to when the previous owner took it to a shop and some jackass probably lifted it on the tab.
basically, you can take either a wooden baseball bat, or a proper fender roller, and roll the inner fender lip flat. that will make the cross section area for the tire to fit in wider, and you won't have any rubbing issues. this is obviously affected by wheel offset (backspacing) in addition to tire size (both width and aspect ratio).
I not sure if that info is corect but thats what i understand....ive been looking for tires also.
With the wheel removed you will need to bang the fender well at the 3 oclock position alot at the 12 and small bit at the 9. Frequently the rear fender lips need rolled on these cars after lowering to keep it from cutting the tire. I personally used a ball peen hammer on a hot day so the paint was soft and slowly worked the lip up. Some guys use a fender rolling tool, some guys use a baseball bat. The ball peen worked the best for me. If it's not hot out a heat gun can be used for the same effect.
After you're done clearancing spray the beat on metal with your choice of paint or undercoating and drive around for a bit. Check the inner fender well and hammer on it more where it's shiny.
A few areas are thick material and takes some significant blows to move. Take care that the hammer doesn't bounce back and slam your rear quarter. Also make sure your rear seat is up and latched in the normal position.
Over a couple weeks check and recheck the fender wells to make sure the tires aren't rubbing.
That's it in a nut shell
