Tire Size

[Zirzow]

I have just lifted my MJ. I have rough country 4.5 inch coils up front and rustys 4" leaf packs in the rear with about a 1-1.5 inch shackle. Right now i am running 235/75R15 BFG at's. What size tire do you think i should run?

There are some pics at this link.

I am running just about the exact same suspention setup. Only difference is my front. i have 4" coils w/ACOS set for am additional 2.5" of lift. The rear is identicle as yours,. Rustys 4" springs and a 7.5" shackle. On mine, I also did quite a bit of fender trimming. The front flairs are up about 1.5" while the rears are up a full 2"+.

I could easily fit 35"s, but my axles can't. I am also still running 3:55's so can't go bigger unless I re-geared. The AW-4 makes this combo driveable ON ROAD.

 

For you, I would suggest this same size with trimming of the front lower rear openings to clear for turning.

 

Here is some pics of mine on 33X10.5X15 BFG MT's on 15X7 AR Outlaw II's and think its a nice combo.

You have a really nice truck. So if i do some fender trimming then i should be ok to run some 33x10.5 BFG muds? I have been wanting to run those for some time. My gearing should be ok. I am running 4.11 with the AW4. How long did it take you to trim your fenders?

I did my trimming in two nights after work. You won't have as much to do as me, unless you WANT to.

 

Just remove your front flairs. Expect the bolts to break. No biggie, just have some replacements on hand. I used 1/4-20X1" a and left OUT factory the metal strips.

Once the flair is off, you will be able to push the inner fender well away enough to see where to cut the metal from the lower lip. You will be removing about 1" or so but leaving the mounting holes. Cut all the way to the lower pinch seam at the very bottom. There is a bolt there holding the fender to the body.

 

I am thinking you may be able to bolt everything back up in factory position and be done. but you may also need to trim a bit from that flair in the same area. In any case, it will be minimal visual effect but get you the much needed clearances.

 

The key is running the correct back space in your rims. 4.5 - 4" on a 7" rim seems right. This way it will stuff under the fender and clear the edges with minimal trimming as described above.

 

Here is a pic of the trimming I described above. this is with 31" tars, so there is much more room.

 

 

These shots below are the same cut fenders with a 33" tar so I could check for clearance. The rim and tar are set to simulate the outer edge of a 33X10.5X15 tar, mounted on a 3.75BS 7" wide rim:

 

 

Hope this helps,
