@Rahimdad, I am not questioning the importance of skills (skills are much much more important than anything else), I believe this is why many of us here, to learn
What I am saying is, that with equal skills in the equal conditions 35'' might be better than the stock ones for Wranglers. Because there are arguments supporting this and not, I proposed doing a test
Also, big tires don't come alone, you normally do new suspension, shocks, etc.. so you can drive faster on bumpy areas, so you can get more momentum for the place you need it.. but this is one more time about driving technics and skills. I think the original topic was more about traction and adherence itself
