Question Tire replacement question

I run a set of Sumitomo HTR Z and one of them went flat and totalled yesterday. So I'm out shopping for something to fill its space. I know it's bad to use a different tire but my question is, given 17000 miles on the other 3 Sumitomos, would getting just one new tire kinda confuse the AWD system?

And what's gonna become of this new one when the rest retire? Or am I screwed and have to fork out $100 for a tire that'll last me 5000 miles *whining *

At the very least you should get two new tires. I had Yokahama Parada Spec II's on my 18" prodrive rims, and my fronts wore out faster than my rears, so I swapped them front-to-rear. That shouldn't be a huge deal for an AWD car.

Having one tire significantly taller than all the other three though, is going to put a little stress on your drivetrain. I'm no mechanic so I can't say exactly what compnent to point you at, but it follows that if you have one tire rotating less than another (a taller, newer tire) then something mechanical will haveto compensate for that rotation.

The other thing that you will run into is that your car wont handle as predictably with one new tire on. that tire will have greater water-shedding capability than the others, and seeing as it would be newer, its tread-blocks would flex more so it wouldn't handle as well as the other three. In a car that is regularly driven at the limits of adhesion, that unpredictability could be a big problem.

If I was you, I'd buy four new tires. If you can't afford nice ones right now, get 4 equally worn used tires until you can afford some new ones. It will cost you a lot more than $400 if you get caught out and clip a guard-rail etc 'cause one tire gave you problems. Your tires are literally where the rubber meets the road. My philosophy is don't mess with your tires, pay for the good ones.

Thats a bad idea. If your other tires tread depth is too far off in 32nds you can ruin your allwheel drive.Check your manual for the exact depth I beleive it is 3 32nds.And as far as putting the new tires anywhere they always go in the rear to prevent a loss of control situation as per DOT specs.
