Hello everyone! I'd like to see photos from your pinch seams mods and what you tried to achieve in tire dimensions doing it... I see that a little pinch weld is needed to fit 225/75/R16 and lot of trimming to fit 245/70/R17.
I cut off about 6 inches from the bottom (I didn't cut it completely smooth/flush with the inner fender. I want to retain some of the strength) and then folded over another 18 inches or so. I covered my cut and fold with Spray-on bedliner and paint. Check pictures 7 and 8 225/65R16 is a 29.3 inch tire, I am wearing 245/65R17 which is a 29.5 inch tire.
