Cherokee XJ How big can you go?
 
Which puts more strain on the drivetrain, taller or wider tires?

Motorcharge 06-14-2013 03:06 PM

Wider. More rubber on the ground means more effort to move means more strain on everything. Both effect it though.

I guess I will stick with a 12.50 instead of going to a 13.50 or 14.50 then perhaps... Thanks!

What axles are you running?

Snowbeast 06-15-2013 01:54 PM

I don't know what it has I bought the jeep 2 months ago and there was nothing in the ad about any upgraded axles... If I was to upgrade what brand should I look into?

A 13.50 wouldnt be too bad. A buddy of mine runs 35x13.5 Toyos on his XJ, no problems

It comes down to axles and gearing. Figure out what you have and work from there. If it only sees pavement you should be ok. Unless you hammer it on the street, then there could be issues with all that rubber on the ground.

It's definitely not a pavement princess, boulevard bogger, or street swamper

What the hell tire are you trying to run at 13.5 or 14.5" wide? Pit Bull Rockers?? Rule of thumb is max tire size of 35" on stock XJ axles, even with maximum work done to them. I have the stock D30/29sp 8.25 with aftermarket shafts, steering, lockers, etc. and I still wouldn't go over a 35x12.5 tire.

Wrong dude. A 28x14" tire would not put anywhere close to the same stress on an axle shaft as a 33x9.5" tire. Larger tire diameter means more stress, it's all based on torque, which is based on tire diameter.

If you are talking about the same diameter, then sure, a wider tire will work the drivetrain harder because it gets more traction.

I wanted to try and stuff some 38's under it, but I am at peace with the nothing bigger than 35 thing... Thanks for all the input and get out there and tear it up!

Snowbeast 07-25-2013 01:38 PM

I guess it's time to find some Dana 60's

Umm where the eff do you live??? I want in on the Rockwells. OP don't go over 35s with stock axles. You could break a rear axle doing a u turn.

I live in the Mecca of Offroad Utah. There is a local place that sells military trucks , axles , wheels , tires ect.
