[Overdrive]

The way I see it, you're never going to get a ton of mileage out of a strictly summer tire, anyways, or else I figure they'd name them "dry weather tires" rather than naming them for a season, which is probably how long they're typically expected to last.

I plan to drive my car until snow hits the ground, so for me I feel some UHP all-seasons are the ticket, but if you live in a place where you don't get terrible weather often, you get to buy a grippier tire that won't last as long.

While I agree the mileage you've gone is extremely short and probably means there's an issue separate from the tire's type, it is a summer tire, and by its nature it's not going to last long. But until a company creates a tire with summer grip and touring treadlife, resulting in them becoming insanely rich, you'll either be getting a lot of grip and little life, not so much grip and plenty of life, or some compromise in between, and be paying accordingly.

...and for what you're paying, and the driving style and habits you've given us, you're much better off finding yourself something that costs less and will last longer since you don't need grip that's going to give you vertebrae damage
