7k miles and tires are Shot!

Do you have a teenager at home taking your baby out for donuts in the parking lot?

7k is definitely not the typical wear for what others are getting based on what I've read from this forum and others.

Back to OP's question....

Something is amiss with 7K especially given that the wear is even across the tire and you are not tracking it etc. I don't remember seeing mileage that low posted here for any other summer tires. Other members probably have the same wheel/tire config. and can give you real life #'s. As a point of reference reference I got close to 20K on 19" Diamaris summers and I wasn't holding back - different mfr. but at least in the same tire class.

You should take it up with the dealer - and possibly with tire mfr. also.

Continuing with the OP's question....

Still wondering what the tire pressures are.

We won't know what the front alignment specs were since the shop won't release them. Too bad.

And I am not sure how the OP has Bridgestone Sport Maxx tires, since Sport Maxx are a Dunlop tire. Once we know which tires they actually are, then comparisons to tread life from other posters with the exact same tire are possible. All the tread life comparisons to all season tires don't matter, these are summer performance tires with a (relatively) soft compound. They should wear out faster, just not that fast.
