1991 Montero RS-how to switch to larger tires?

[ukrotony]

I am just about to start prepping mine for the summer in Southern CA-dirt, dust and lots of rocks...any advise is welcomed, particularly how to switch to larger tires, do a minor lift and remain financially independent, if anything needs to be done to get he car running properly if I feel like going up on the Big Bear to ski in July, then come down and 2 hours later incounter some major heat and dust...I hope you guys get the idea! I am new to this forum, I hang out at 4x4wire.com usually...

You should have no problems with putting 31x10.5 on your stock Mitsubishi. You may be able to put 33x9.5 if you want to, but I can not confirm this myself. Let me know if you would like some more info on tire types as I've tried a few over the years.

OK is yours a Gen 1 or 2 ?
If it's a Gen 1 you can run 32x11.5x15" on 15x8" rims with no lift or 33x12.5x15" with a 2" suspension lift providing you use the correct offset rims.
The torsion bars can be wound up to get 2" of front lift and by cutting the upper bumpstops down (x4) you will still have some downward wheel travel.
I'm guessing yours is a coil spring rear so 2-2.5" lift springs are the go I think Valley Springs is the place in the US. Their original springs were progressive rate and were found to collapse quickly but I think they have released a new linear rate spring. The US boys wreckon their customer service isn't the best though. You will have to match the shocks to the taller springs to make the most of available wheel travel.

Being the cheap bugger that I am, I simply cranked the front t-bars, and swapped in GenII rear progressive coils. I am running 33x9.50BFGs on the stock rims, and in snow, this thing is practically unstoppable.

Bigger tires on a montero....

Step one: remove old tires.

Step two: bolt new tires on truck.

Step three: laugh because a jeep would have needed 5 inches of lift to clear the same tires.

Yes that amazes me about Jeeps.
However I wish we had the aftermarket parts they have available :mad:
But if only more manufacturers would bring out models like the Jeep Rubicon
Rumour has it there Mitsu factory lockers their using.

Kinda. Its made by the company that made the mitsu air locker, similar technology.

Fuji Tujitsu something or other, I forget. Mitsubishi may own that company, but they dont operate under mitsu.

Definetly not that factory axles we have though.
