Okay, I have a 91 YJ with stock rims, a 3 inch over all lift with longer shackles and a 2.5 inch spring lift. I run 31X10.50's and all is basically okay.

The fact that you will get mud up on your own windshield is normal.

IT'S A JEEP THING.....

I would seriously go with stock rims that keep your 31X10.50's right around the edge of stock flairs. The only thing that you will need to do is adjust the factory bump stops. It will cost you a whopping $0.50 or less to do this. There is a thread under Jeep Tech FAQ that covers how to do this.... It really is simple and will keep your tires from rubbing on your springs!
