Okay here's the deal. I'm ready to upgrade my tires from 33" dunlops to something in the 35" variety. I've narrowed it down to either 35-12.50-15 Goodyear MTRs or 36-13.50-15 Iroks (bias ply). If I go with the MTRs I'm going to keep the 15x8 steelies I have on now. If I go with the Iroks I'm thinking about using the 15x10 Colorado Customs I haven't had any luck selling. Here's my concerns: Are the Iroks, and Super Swampers in general good quality. I've heard just enough to be worried, stuff like being out of round. Will my aluminum rims be okay now that I have a tire with a cross section of 14.5" instead of 12.5" I did have on them. If I don't get the Iroks I feel like I'm going to always wish I had. Here's the pros: The Iroks sound awesome from everything I've read. I really like the idea of keeping the Colorado Customs The Iroks are cheaper. The MTRs are highly recommended. I trust the Goodyear brand. MTRs are quieter (for the wife's sake) This is not a daily driver, only drives to and from the trails and camping with pop-up camper.
