I have them listed in my LRR tire threads. http://priuschat.com/forums/gen-iii...resistant-replacement-tires-current-list.html
you have EP422 but not Dueler H/L 422 which are for SUV/minivans and don't come in Prius sizes. Interesting to see Bridgestone claim 36% and 42% rolling resistance improvements.. how much that would be compare to EP100 and Michelin Energy Saver A/S?
Why would I put the Dueler on my list? lol They likely would score lower in in reduced RR (worse) since the Energy Saver A/S outperformed the EP100 in TireRack.com's test and the EP100 is a summer tire which doesn't require a more aggressive tread like an all-season tire (EP422). You may be able to contact Bridgestone to see how the numbers compare to the EP100.
Granted the more aggressive tread will be decremental but not sure they are worse as B-stone claims improved sidewall with 422.
If you could get more information from Bridgestone I'd be happy to include it in my LRR tire thread. A lot of people like these tires and the reviews are great so the more info the better. Thanks.
