Was that both with the Mopar and Synergy LCAs? No problem with fender clearance with the Mopar bump extensions?From my experience running +25 on a 8.5" wide wheel with 37x12.5r17 tires a +30 will rub on the LCA's pretty hard at full lock. If you had a 35" x 11.00r 17 tire on a 8.5 +30 wheel it might not or you could probably get by (doing what I did) turning out the steering stops a little. I don't have a visualizer but 35x11.00r 17's on a 8.5 +30 should be flush.
Hear is mine with a wider tire 12.5 and +25 wheel....
