Tread depth mismatch on same axle

Im leaving on sat for a 600 mile round trip vacation, with some wheeling in the middle. I thought my spare was brand new, so I only bought 1 MTR without checking...

Ya intelligent..

Anyway, the spare has ~16.5-17.5/32s I would say closer to 17 than 16. Unfortunatly, my guage reads 15 then 18 so Im guessing, but I would say much closer to 17 than 16.

Brand new tire is 19/32s.

I am thinking this difference may be too great, and could tear up the rear diff. Am I correct? Is 2/32s gonna gernade my rear, or will it be ok?

Id rather be safe then sorry, but there are NO MTRs in MD other than the one I bought, and id rather not go muddin' with my 6/32 rears that are cupped and loud as ballz

let me know please, my buds gonna rebalance and install the new one tommorrow.

thanks guys.

You could rotate your fronts to that back so you have a matching set on the drive axle. It will pull a little this way, but won't hurt anything. I really wouldn't think 1/16" would hurt anything in the rear.

They really kinda of have to be in the rear The fronts were on the rear for 15,000 miles, and have only been on the front for 1,500

I wouldnt think that 1-2mm would really effect the U-joints and rear diff enough to make a diffference right? I mean the roads themselves are 2mm off.... If it was 7/32s sure, but 2/32s I dont think is an issue. I guess ill wait untill Jerry, Mr.Cliff, bluviking, amerijeep, etc. chime in.

thanks daddyjeep.

That little a difference isn't going to hurt.

I have to agree with the responses you have gotten. You will have that much difference from the left side of your lane, to the right side. If you can put it on the drivers side, you will not notice a thing.

Nah you'll be fine, you can run a slick on one axle and a Mud Terrain tire on the other (same height tho) and it wont damage your gears, it will pull like a MOTHER tho!the diffs in the jeeps(and most cars) are built with this possiblilty and allow slippage......and you wont really notice a pull till one of the tires is pretty darn low anyways.......SO have fun on the trip and keep track of gas mileage...let me know what you get!!
