bigger tires lose torque? HELP

Is it not true that I am losing torque by putting bigger tires on my truck? I have 30.5 x 10.5's on there now, but i feel like with a 2.5 engine im hurting more than helping. but it feels faster than with my stock tires. So would the better trade off for offroading be to take the bigger tires? help.

You do lose torque but if you are saying your sticking with 30.5 tires then there shouldn't be any significant loss, but I may be reading your post wrong

You don't' have to worry so much about loosing toque when your around the 31' tire range with a more aggressive tire tread. You'll here more noise, but it's all good.

If you want to bump up to bigger tires and a lift up to 35' tires, you'll need to re-gear down to 4.88. That change will make the trail *amazingly fun* with the 2.5's torque, but your rig will do about 70mph max on the freeway.

It's a trade off.
(that's worth it)

how exactly is a re-gear done, and how much am I looking at money wise? I can't do it myself.

Also, what kind of obstacles are you able to overcome in regards to mud/water. I'm always worried I won't have enough power. and what kind of inclines can I handle?

Gearing your Jeep 2.5 to 4.88 gears is an entirely different subject that you can find about with some research around here on the forums.
