Default all wheel drive and tires

I hope someone can give me a good answer to this one. My all wheel drive durango blew out a front tire. I replaced the front two tires and left the rear alone. The difference in the tread depth between the new tires on front and the rear tires is 3/32. My dealer said that that is OK, but the tire dealer said I have to replace all the tires if there is any difference in tread depth due to a transmission wear issue. Whats the truth. What does Dodge think? I cant find any definitave answer from Chrysler. Thanks. LM.

A .090 difference in the diameter is not going to create any issue with the transmission. Sounds like the tire dealer was looking for a sale. That's the kind of thing that sends me elsewhere to do business.

I'd tend to agree with Sarg! The Jeep Qradra-Trac system is the only AWD system I've seen on domestic 4X4s that is sensitive to tread depth differences.

I agree guys, it sounds like someone was trying to seel 2 more tires valve stems and maybe an extra alignment!

The only thing you must be careful of is changing tire models and brands. Just because you have a 235 75r15 in one brand, doesn't mean it matches height with other brands or models. (Yeah, I know that it is supposed to, but it doesn't.)

Suggestion: Check your mounted tire height front and rear. If they're not pretty close (Within 0.1") you can (depending on design) create issues in your gearbox. Keep 'em close.

If you think that the difference of just under 1/8th of an inch of a tire's diameterhas ANY impact on the "gearbox" .... I'd like to better understand the "issue" you're talking about.

I have 14k miles on a Pacifica and I just acquired a factory wheel and a new tire of the same make & model as on the car. I am going to put the new tire on the car today as part of the rotation .... and imagine there is "at least" 1/8 inch difference in the diameters.

I anticipate ZERO problems.
