Anyone run 13.5 et streets on an 15 x 10 inch rim with 5.5 backspace without having to roll the lip on the rear quarters? Thanks\

I'm running 11.5"x28 et streets on that spec of rim and I don't think there would be room for 13.5 without rolling the lip. You might squeeze it in but don't be surprised if you have to roll the lip slightly.

I have run the 13.50 x 28's on a 10" with 5.5" BS and I did have to trim the wheelwell lip for them.

12.5x28 sportsmans will fit but that's not an ET, but should be the same...

ss540, How much of the fender do I need to trim to make them fit? And what tools did you use to roll the lip up. thanks

Jr.

First, let me say that i'm not afraid to modify things to make something fit that the factory didn't allow room for. Second, keep in mind that once you cut or "massage" the sheet metal, there is no going back unless you weld in new metal. It's also easy for tools to slip and damage the quarterpanel, either from the inside or outside.

But with the warnings out of the way, I used a cutoff wheel tool to cut the lip off. I have done this in stages, going to wider tires each time and cutting closer to the quarterpanel each time. Currently there is about 3/16" of the lip remaining.

I suggest trimming the lip back to about 1/2" from the quarter. You will also have to "massage" the inner wheelhouse in a couple of places with a sledge hammer. May even have to cut some of the outer wheelhouse near the quarter.

Did you use masking tape around the lip? I heard it helps keep the paint from cracking where you use an cutoff wheel? Thanks again,

Jr.

Yes, I used the low tack blue masking tape on the quarterpanel.
