It all boils down to a couple of things:
Do LRR tires by General roll any easier than non-LRR tires from Kumho? Factor: The new tires would weigh 3-4 pounds more.
And: This would be offset by the new wheels being up to eight pounds lighter than the existing ones.
More research / other possibilities ...
Firestone Destination LE2 HAS --- P235/75 R15 108T XL 2183 lbs./50psi 12.0/34" 34lbs 7.4"
Two pounds heavier, but a much more highly rated tire than the Grabber HTS. Probable difference from the Grabber in fuel economy?
I don't have revolutions per mile for some of the tires in the list, and I'll work on that today.
