sounds like neg camber issue, maybe worn suspension issues contributing.

Cornering in one direction leans on inside of one front wheel and outside of the other front wheel. so I don't buy the argument that hard cornering leads to uneven tire wear and death at 6-12K for a non-performance tire. Runflats in NJ last for approx 20K and people leasing cars have a heart attack when hey hit the 20K ish k miles.

Well, they are a supposed performance tire...it's right in the name... Fuzion U(ultra)H(high)P(performance)... However they were the cheapest thing I found from a brand that I had heard of...

Didn't know what uhp stood for.what are they rated for treadwear wise? The massive uneven treadwear is still troublesome. Was either car aligned when the new tires were put on?

The car was aligned about a month before the new tires, maybe less... I think the tires have a 300 tread rating.... Not 100% sure though

300? Yikes.
Obviously, the UHP tires are not meant to last being that soft a material. They grip the hell out of the road--at the price of not lasting very long at all. Sounds like a tire to go on your "fun weekend car". Spirited daily driving, as demonstrated, will chew through them.

IIRC, the Sx2 cars (at least through 97) came with Firestone Firehawk GTAs. They were a performance all season tire (per description) with a 40K treadwear warranty.

My point in bringing those tires up is that you may wish to investigate a harder tire, prob w more tread depth, in the performance all season category.
