New tire advice

I recently had a blow out on one of my tires which gives me a great excuse to take advantage of labor weekend sales and getting new tires. I've been imagining upgrading to some 33x12.5x15s the only thing is I'm still running 4cyl 3.07. What's everyone's take on this?

4 cyl 3.07? If you had that, you would need 4L to get up the driveway. You would cruise in 3rd gear (manual trans) on the highway with tires that big. Do you mean 4.0L 3.07? Or 4 cyl 4.10?

Woah my mistake, yes I meant 4.0L with 3.07.

You can, just won't be able to use 5th gear at ALL. I had 33s on my 4.0 with 3.07s, just swapped to 4.11s and love it. It now drives as it should.

I second that...just went to 4.10 also and everything back to stockish feel. You can do it but after a while it gets old. I ran with 3.07 for a few years and it sucked.

I had a 8.8 built with my options and had NEW gears installed from east coast gear supply(ECGS). When you get new gears, they replace all bearings, as well as a warranty on the axle. I got a donor junk yard front to match, 4.10. The 4 cyl 2.5 l came stock with them. I run 33's and it's a great setup for a daily driver and rock crawling or mudding. Total cost for the rear axle was over $2500 but I also had an ARB selectable locker installed and new brakes, calipers, and pads, solid diff cover( love it and worth the extra $75!!!)

I actually just swapped both axles from a 4cyl. I got both axles for $700 and the shop charged me $400 to swap them out so total $1,100. Worth every penny so far!

I'd say check out BFG K/O2s, K/M2 or Goodyear Wranglers MTs, the MT and K/M wont last more than 50K probably, but they'll grip like super glue.
