sounds like you want the rt-615. It's not as grippy as the re070's or advan's but it's pretty good and the price is right.

 

1000 miles per week? I'd say you're a prime candidate for owning two sets of wheels so you can have your high-mileage tires and your autocross tires separated.

TireRack invented this "extreme" term but I suppose it is appropriate. Most of those tires will last 15-30k miles depending on how gentle you are. Other summer tires can last quite a bit longer while being comfortable and quieter. I think if I drove 1000 miles per week, I'd get something like the Falken FK452- cheap, quiet, good in rain, and long lasting.

You will not be competitive in autocross without the stickiest rubber, though.

 

I know. I drive a TON. But in my STi it is always a joy! I wish I could afford two sets that would be great but my "accountant" is not likely to ok that. What exactly is not competitive? At my first ever Autox in April, driving on the Generals, I placed 4th out of 6 in STU and 39th out of 91 overall. I plan on doing more soon and am attending an Autox school in July. I don't plan to win any but I would like to be in the top half at least. how would the FK452 or one of the others do for that? I am generally easy on tires the rest of the time with a Lot of highway miles and regular rotations. Several people have said the RE-01R wears much better than the Falkens and is worth the extra money but it is a lot more money.

 

I have the Falken FK-452's and so far so good. I have put about 4k miles on them and am liking the ride as a daily driver tire. They are much quieter than the 070's as well. as far as grip goes, believe it or not but they actually grip BETTER than the stock 070's. Response is where the 452's don't match the 070's. The 070's kind of feel like a go-kart when you turn the wheel, instant response. The 452's respond well but there is a definite lag there. All I did was alter the way I drive and now don't notice it as much..................the lag is still there though. I would recommend the 452's as a DD tire but I am unsure if I would recommend them for serious auto-X. Maybe the occasional Auto-X but not for if you are really serious about it.

 

are you comparing fresh 070s to fresh 452s?

the 070s start to die off pretty badly after they get heat cycled too much and past their wear bars.

as for the OP if you're competing in STU you'll want to run a 245/40/17 tire and that isn't available from every company.

from the sounds of it your STU competition isn't super crazy and your main priority is having tires that last more than 2 months/8k miles + autox.

go with the FK452s in a 245/40/17 and see how you like them.

worst case scenario they fail miserably at autox and you convince the accountant you need a set of 17x9 +45mm Kosei K1TSs and some 245/40/17 Bridgestone RE01Rs for Autox (which would last at minimum 2 seasons if you didn't drive on them regularly) and some high mileage long lasters for the street.
