What tires to put on my cj7 build.

It has 30 x 9.50 x 15 on it now. I think original Jeep rims. I want. 33 x 12.5 x15. I want something that looks aggressive but in reality this will be a mall crawler. Any suggestions??

I would rather have a tool I don't need, than need a tool I don't have.

Do you have any lift?

Also, what engine, trans, and gears?

If you had to choose between World Peace and a Jeep, what size tires would you run?

I am not sure of the lift. It is suspension and sits very close to my cj5 which has an SOA and 33 tires. I put a 360 amc in it

You will need at least 2.5" to run 33s. That is pretty much the minimum.

2.5" is not enough for true 33", you need closer to 4". (Many 33" tyres only measure 32", not such an issue).

It is the width of the rear wheel boxes and lips, you need to get the tyres lower so they do not rub the front and back of wheel box on full extension. With a leaf spring suspension, the upward extension is limited.

Of course, if you never flex at the mall you may never find this out. Lots of rigs out at the mall could manage with no lift.

Mine is a weekend cruiser, so 2.5" with 33s works great.

Of course, if you want a mud tire, there is the Interco Tryxus M/T. I have these on my CJ (with a 4" lift).

When I ordered the new body mounts I ordered the ones that included an one inch body lift. It appears PO installed new springs that should give another 4 inches. I remember a friend had Mickey Thompson tires that looked mean.

How would I measure lift with the body off. If I go from 30 inch to 33 inch on the same rims what lift would I gain.

It depends on the actual tyre diameter. Most websites will tell you this. A 33" can be 32" and still marketed as a 33" 9I woudl feel cheated).

Originally it had 29" diameter tyres, so a 33" true tyre will add 4"/2 = 2" of extra clearance under the axle.

I have a set on my xj and they are fab. However all my CJ have Mud Terrains or what we used to call Town and Country tyres. This is because my Cjs move more slowly and pend less time on fast highways, more time on tracks and off road (or broke down, but we do not count that).
