Firestone Potenza RE910
 

Any info on these in terms of rolling resistance? Thanks

There's links about tire pressure and tire width in my sig. In those threads there have been a few links posted to PDFs and threads on other forums where RR was reported.

However, if your long term goal is to save money, the best strategy is probably to get tires with long treadwear, or a good treadwear to price ratio, and inflate them to their maximum rated pressure or the highest pressure that provides good handling, whichever comes first.

do you mean bridgestone?

IMHO:

they are over rated and over priced!

kumho or sumitomo offer better performing, less expensive, and less rolling resistant tires.
