Will 33's be too big?

I have a Rough Country 2.5 inch lift on my 77 CJ5. The tires you see are 31's. based on the photo, would I be able to run 33's. it would only be an inch taller into the wheel wells. Most of my off reading will be seeking out fishing holes that few go to. That said who knows what the terrain will be like.

Is your lift older? Remember that the springs will start to sag over time and that will alter your clearance. I did not like the way 33's looked with my 2.5" lift so I put a 1" BL on but my CJ is a pavement queen with only light two track use. For $130 you can't really beat upgrading the stock rubber bushings with polyurethane and the extra clearance.

They might rub on the back edge of the rear fenderwell openings. Mine did with 2.5" of lift and 33s.

33"s will likely rub, as CSP said.

Here is mine with a 2.5 lift and 32"/11.50s. BFG ATs actually measure about an inch smaller than the advertised size when brand new.

As you can see, they only clear by about 3/4".

No rub on mine but I have a 1/2 inch of shackle and pretty beefy BDS springs.

Mine were fine in the front with a 2.5 lift, but I trimmed the body in the rear, changing from a 1/2 cicle to a nice diagional at the back and now its perfect.

I'm thinking of adding a 1/2 shackle lift as well. I suppose I could do that after the tires if needed. Are those Super Swamper LTB's on the blue CJ5?

Nah they're just old regular tsls, with boggers out back.

Im keeping a eye out for 34" LTBs though Im positive they will fit. If I dont find any Im just gonna spring over and get 35s.

I've thought about doing a spring over, but am concerned about the chance of rollover. I am thinking about 33x13.3 LTB's right now. Then adding Warrior Products 1/2" shackles if needed.

That should be 33x13.5

Be advised, longer shackles will change the caster on your steering geometry, making your CJ a handful to drive.

You will have to correct for that.

It is already a handful now, so I will head you advice. I'm going to look into the body lift. How hard is it to do a body lift, and would it bring its own set of problems with it?

33x12.5 15 on wagon spoke. I did 3 .5 inch springs and .5 shackle, with tube fenders up front, it JUST cleared. In the rear, It just touched the bottom rear fender. To me, it looks like you need more lift for 33s.

Body lift is straightforward apart from rusty bolts shearing off. If you take it more than 1" you will need to consider the steering shaft, brakes, clucth linkage, shifters etc etc. However all this does is raise the body, it does not make the wheel boxes any longer and you will still rub the tyres.

Also before you go for larget tyres consider the axle gearing and what you will be able to use it for and the costs.
