Biggest Tire In Stock Wheel Well?

275/60/15 will hit spring mine are 8.8 wide and 28.1 tall bf drag radial
I had to move springs in mopar sells offset spring hangers I think they move it in .75 inches and they are pretty cheap and easy to install
you cant go taller than 29 inches tall they will hit front of rear fender opening
also probably not recommended but I run a 7 in wide wheel for the fatter bulging look and they hooked better at the track
getting the backspacing right is critical and probably better than just asking would be to look up a post on how to properly measure for the correct backspacing it is really easy and would insure that you didnt waste your money on a set of incorrect wheels
also the backspacing if you are running the stock a body rear axle width is going to be a custom order I dont know of any stock wheels that would work but maybe someone else does
I narrowed my axle while I was rebuilding it because you can use all of weld, centerline, or summit brand alum star wheels in standard offsets and they dont hit the outer fender lip with the bigger tires on them
the extra money that it cost to narrow the axle was offset by being able to purchase used standard wheels from ebay the standard offset summit 7 in wheels are only $100 new
I like to switch wheels and now I run rally wheels on the street with spacers
and when I go to the track or am going to rip on it I switch to the alum wheels with drag radials and no spacers and that also lets me run the new challenger/charger 18 in wheels for the ladies
hope that helps
