A few questions on tires
 

I have the stock potenza's on my vehicle. My rear tires still have great tread life, but my fronts need replacing very very soon.

My question is, should I buy 4 tires or just 2 tires?
I can buy 2 used fronts and have all 4 tires wear out to get the most wear for my $, or I can just buy 2 new PSS fronts and run different tires f/r.

Another option is just to replace all 4 with PSS'.


Also, I've noticed a few people running v12's in the rear with RE11's in the front. What is the benefit of that? Thanks!

If you can get used tires for CHEAP do it. I've noticed for larger wheels it usually doesn't average out to a better deal

Oh, and Michelin has a deal on tires, buy 4, get $70off

Lastly, if your camber isn't stupid, (and you choose a tire with a mileage warranty) get your tires from Costco. You get free road hazard protection and such. And if let's say you buy Michelin A/S+, warranted to 45k miles. The warranty ONLY for the rears is cut into 2 because you can't do tire rotations, so 22.5k...
If you come back with the rears wore down in 11,250 miles (half of that warranty) Costco will give you half your money back towards a new set of tires.
The other tire places go by tread depth, and 2/32nds is bald, so you get $0

do donuts like a mouse that got its foot stepped on.
