Lift and Tires - Help

Soon I will be needing new tires. Before I buy new ones I am curious as to what is the largest size that can fit on a near stock '92 YJ 4 cyl. w/o a lift. Also, what is the largest tire that can be run with a 4 cyl. The tires I am looking at are BFG A/T's, BFG MT's, or Goodyear MT/R's. Thank you.

Re: Lift and Tires - Help

I would go over 30s without a lift.. They will squeeze in fine.. go with MT/Rs.. There isnt a Max tire size to use with a four banger.. it comes down to regearing, adding accessories..ect... but if you go much larger than 31s and dont change gears you'll feel a huge difference. It all depends what you want to do? Do alot of highway travel? I wouldnt get to big of a tire. Goodluck

30" with no susp or body lift. 31's will rub at times unless you run stock or near stock wheel offset. a simple 1" body lift would be a good step to make to clear 31's. then it can be used in conjunction with a susp lift later.

If I were you I would exceed 31's without regearing. For every inch you go up in tire size, you lose .10 in gearing.

i've got 30's right now and i noticed a gearing difference although not bad. just hit 5th gear a little later and faster! the 4 cyl won't be the prob- rather axles, tranny when you go real large tires ie over 33's i have heard.

Follow the "Gator Chaser" link in my signature and find the part about 31" tires on a stock Wrangler.... I have the 258 engine and had a 5-speed manual. I could still use 5th gear to cruise with, but it certainly wouldn't gain speed in 5th!
