Different size tire front/back

OK, I get it. I was in a bad situation and these were the only tires I could find. Afterward I realized what I had done. Thanks everyone

I recently had a pair of brand new and a pair of 'slightly used' tires put on my truck.

The shop put the brand new ones up front.

Well, there was enough of a size difference to cause the TOD to act up. I felt a vibration or buzz as I was driving, the next day I had them swap front to rear, and the problem went away.

My logic is that putting the 'larger' (new) tires in the front actually forced the TOD to constantly compensate for the slower rotation.

Switching them alleviated the problem.

But I am ordering 2 more new tires just to be on the safe side.

Any vehicle that uses a form of all-wheel drive should have tires of equal outside diameter. Otherwise there will be significant torque-bind in the driveline causing excessive wear or even catastrophic failure.

this is where your stock VX "LOCKED" all the time hub flanges will kick you in the pants and Manual hubs will come in handy.

If you put a different size on front and back on both sizes you could break the teethe off of your pinion flange, as the same thing happened to me.

When the Goodyear tire shop said we only have two of the 34x12.5x17's so we'll put them on the rear. You can come back in a few days and get the other two for the front. I currently had 32x11.5x17's on it. So, I said ok , but something was saying wait a minut, but I had to get to my dying Grandmas side and my rear tires were shot and I had already ordered the whole set and two just happened to not show up so I said If you say it won't mess anything up.

They put the two on the rear and off I went. Well, A weird noise immediately followed and then on the way home that night it started grinding. Grandma died next day. I tore out 3rd member and the pinion teethe were destroyed.

That is when I installed my first set of AISIN manual hubs and a used 3rd member from the junkyard and went to get my tires. That Goodyear tire shop told me I was SOL even though they told me it would not damage anything and that they were not covering any of my damages. So, I paid for one $300 Goodyear Wrangler MTR, put the other 3 on their Goodyear Tire card and added it to my Bankruptcy.

With the Manual hubs you can put whatver size of tire differance or gear ratio differance you want on the front and back and put the hubs in FREE.

Put it in LOCK and you get the same reation as our flanges in the VX.
