Okay I have another question for you guys. Yes it's true I have the tiny 4 banger in my jeep, laugh away I know it's ridiculous. I am running 35" tires right now w/ 4.88's and it does ok on the road if I am not in a big hurry.
So I have done some research and found out that my current 35" xterrains weigh 65 lbs. a piece. I have also been looking at the 36"x13.5x15 Irok's and found that they weigh 66 lbs a piece. So my question is this, if I went to the 36" tire that weighs 1 lb. more what will the big deal be. Is it going to be harder for the banger to push them or will 1 lb. not make that big of difference. Or will the surface area of the tire create a whole new animal for the banger to have to push?
Any thoughts or suggestions.
You
especially don't want an IROK with a 4cyl.
It has been scientifically proven that IROKs produce enough suck to actually cause a rift in the space/time continuum. Iroks require massive amounts of wheelspeed to gain any sort of traction advantage over the common RV tire. Your 4cyl does not have enough power to turn the tires and if you add enough gear reduction to do so, you'll run out of engine too quickly.
It's a 4cyl, so it will suck on the highway no matter what. With enough gear reduction, it will be livable in the rocks. The xterrain is also a lackluster tire as well. You'll be very happy with a 35 MTR, KM2, or Krawler and a low gearset in the Tcase.
Bottom line: If you are underpowered, you'll always be better off putting money into a sticky tire that can crawl an obstacle, rather than blowing up parts trying to bash your way up.
