Thanks for all the responses! You all seem to confirm my gut instinct to go for the higher E-load rated tire. I guess the 'max load' is different from the 'best load' when you are approaching the limits of the tire. I just ordered some of the E-rated Sumitomos from Tire Rack for pickup from their distribution center but actually just found some supposedly highly rated Cooper Discoverer HT3's for $100 each ($50 off!) that are also E-load rated and 5 pounds lighter so might switch up my order. Unfortunately they aren't on Tire Rack so I can't comparison shop, but they have some decent reviews and a 50000 mile treadlife warranty to alleviate any fears of poor longevity (as I read in some of the poor reviews). Anyone have any experience with them vs Michelin Defender LTX M/S or the Sumitomos?
