next time you fit new tires prehaps you can fit tires that are within the cars specs but narrower... this will of course alter the cars ride a little, so perhaps it might not feel like an upgrade (although narrower tires are better in the wet where you're most likely to get in trouble so it's not really a downgrade in all respects), it will reduce frontal area and rolling resistance. alternatively you could go with a set of low rolling resistance tires... i hear the new ones are about just as good when it comes to grip as standard ones. that's not gonna work miracles, but it'll add to the rest
