Do you have access to the difference between the RSA and F1 All Season...specifically about:
- How many miles you can get from each tire
- Is your gas mileage better / worse, and by how much?
I eeked out 50k on the original RSA's, and am not too keen on spending $234 at TireRack (or $290 at the dealer) just to hydroplane for another couple years.
Luckily I actually had a conversation on this topic recently with one of the few people who's opinion on tires I trust 100%.
The RS-A tire is an extremely high Rolling Resistance (RR) tire, causing it to greatly impact the fuel economy of a car. The GS-2 on the GXP is actually a very low RR tire which helps the GXP get better fuel economy over the Classic on RS-As. The new F1 All-Season (sometimes referred to as the F1 AS) is apparently one of the best all-season tires you can get. It's actually superior to the GS-2 'summer' tire on the GXP in all forms of handling and performance characteristics. However it's RR is slightly higher than the GS-2 so fuel economy values from it wont be as good as the GS-2 (still much better than the RS-A though) but the gain in performance is more than worth it.
Wear wise I can only speculate.
- RS-A - Treadwear: 260 Traction: A Temperature: A
- GS-2 - Treadwear: 300 Traction: A Temperature: A
- F1 AS - Treadwear: 420 Traction: AA Temperature: A
I drove the RS-A on my base car for 13k miles doing several auto-x's on them, and then the owner after me drove them till 35k miles before replacing them. The GS-2's I shredded through in 21k miles on my GXP thanks to it's higher power levels and doing some auto-x and 1/4 mile runs. Looking at the treadwear values one would surmise the F1 AS should last as long as the RS-A if not longer.
