Ok, it's time for me to re-gear. I have 3.50 gears and 33's, 5.0 EFI and a C4 (both fresh and strong). I'll probably keep my current tire size for years. I take long trips and do some towing (1,000-2,500 lbs) during hunting season. Most of my towing will be up in the mountains. I know 4.11 gears...
