Hear a lot of people complaining about the lack of choice in 265/45/21, but for summer tires there are a few top brands to choose from, besides a lot of asian unknown's. (1) Pirelli P Zero (great tire but due to compound wear's very fast) (2) Dunlop SP Sport 01(good allround tire) (3) Dunlop sport Maxx RT2 ( just released a couple of months ago,rave reviews, sticks to the road like gum and very low noise. 68-69db) (4) Nokian z line SUV ( good reviews and ratings, price is low compared to the first 3, a lot of german Cayenne drivers use this tire) I don't know if these are all available in the states? They ain't cheap, about 280-300$ a piece(except Nokian) here in europe. I'm running the SP Sport 01 at this moment, but will probably be upgrading to the RT2 at the end of the year. As far as PSI go's, you guy's run them soft! I run mine at 44-45 PSI, and thats pretty common for that size tire over here, otherwise there's too much pressure on the in and outside, and steering gets way too heavy!
