33's or 35's tires ?

Im at delimma. After looking at the thread with the 4" lift and 33's, I have got 2" shackles and a 4" BDS Spring lift I got on craigslist. Once all installed, 33's or 35's. Im running 4.10 gearing. Would 35's fit without having to trim. Or go with the 33's with no fitment issues?

I think your gearing is well suited for 33's. Your lift should handle 33's with ease. At least mine does. I think you could go probably run 35's but under exteme flex you might have issues? If you dont take it to the extremes you'd probably be ok.

I agree w/ 33s. 35s are just getting too extreme w/ stock axles.

There are a few milestones in Jeep setups - moving up to 35s is one of them. Granted, a stock drivetrain will survive with 35s IF the driver takes it easy. But, it's more than that. From the steering gear (stock box/pump really is not up to the task. Yes, it'll do it... for a while, but not well) to the gearing, 35s just mandate a bunch of changes. Plus, there's a good chance 35s will hit the back side of the rear wheel openings. Yes - all of these can be overcome, and have been for decades. But 33s are almost plug-n-play.

The funny part about this - 33s vs 35s debate - is that guys with 37s, 40s... laugh. To them, 33s and 35s are for tow rigs.

To me, anything larger than 33"s looks out-of-portion for a CJ's body size and narrow stance. Kinda like Grave Digger's runt brother.

But that's what's cool about these old heaps, the build options are only limited by your imagination.

I think it's only CJ7's rear wheel opening that looks perfectly matched to 33s, and out of scale with 35s

The scale looks off a bit here:


But swapping to TJ/YJ flares cures that:


And, with the added length, CJ8s look even better with 35s... okay, I'm a bit biased

If those BFG MTs are anything like my ATs, they don't actually measure 35".

My 32"s were only 31" brand new with 32 lbs of air. I'm not sure how they get away with that.

If the CJ where home today (at the shop), I'd measure... but I'm pretty sure the 35s would measure right at 33" - as most 35s do. Intercos (Swampers and Boggers) are the only tires I've had/measured that measure true - the 35" Boggers actually measured in at 35.2" when new.

Diddy2003's 33" MTRs look HUGE. He said (other thread) they measure close to some 35s.

I have a set of Firestone MT's on my cj7. They measure 32.75" on 15x10" rims, 35 psi and full vehicle weight. Also they have only 500 miles on them.

Yep. To me, that's BS false advertising. How in the world can they sell a tire that's 2" smaller than advertised?

Not to mention how that throws off gearing and lift height calculations.

Anyway, I just thought I'd point out that tire sizes vary depending on brand, and they rarely measure what they are advertised to be.

Lol; my bad!

Here's a crummy pic of my glass/kevlar tub w/ 4" ROUGHEST ride COUNTRY lift and .75" shackles. If you can make out the tire they are 33" BFG A/Ts. There is a 12" gap. I wanna go w/35s. Since the springs won't flex I don't have to worry about the tires hitting!
If they don't settle by fall, I'll pony up cash for decent springs. Likely SkyJacker soft rides.
The rear is a D-44 w/4.10 Yukon gears and a Tu-Trac. Tru Trac doesn't reccommend anything over 33s for their unit.
As far as tires go, G-Year seems to be the only ones who give out actual specs.

Hutch, did you take that pic with a calculator?

With my first CJ (circa 1993), I had 33s and wanted 35s. I pulled a tape on my tires and a couple friends tires - who had 35s. I then ordered a set of 35/16.50/15 Boggers. When I got them, I thought "Oh #$*@ these are big" They were a full 2" bigger than my buddies 35s (don't remember the brand). Had to fire up the sawzall...
