No clue- but my blown rear shocks made short work of the inside edges of my rear Bridgestone G019 Grids after 10k miles. I still had 7/32 left all around, but the inner edges looked like they'd been feathered to hell and back. I bought the 5 used with a new set of tires on it from the dealer, so I have no clue how much the stock Toyos (?) would have looked on there.
As for replacements, I prefer the largest rubber I can stuff into the wheel well generally from the summer "ultra high performance" or all-season "ultra high performance" categories. I read through tons of Tire Rack reviews, look at personal experiences on the forums, and ride in as many cars as I can with different tires to try them out. If you can afford them, Bridgestone's and Michelin's top of the line summer tires are really nice (S-03, S-04, Pilot Sport), but they're not good in the cold and snow which you'll probably need up around the Great Lakes.
I run the Sumitomo HTR-AS P01 (I think, whatever sounds close to that) and it's ok in the dry, but crap in the wet. I've run quite a few Kumho tires in the past with success- they offer a great balance of grip/price/longevity. Look at the ASX or 4x models for all season, SPT or LX (I think) for summer. I'm running Hankook R-S3s on another car- they're way awesome for dry grip.
Don't pay attention to general brand recommendations either. Tires vary quite a bit from model to model within a brand, and even then from size to size because of differences in tread pattern and compound.
