I have wound up with 2 sets of 175/70/13s, and want to mount one set on my Civic VX rims. I would rather some 155s, but like the title states these were free so they will do for now. One set are Kuhmos, and the other are Michelins. They both have about 70% tread left on them, so I figured I would try to decide based on the Treadwear/Traction/Temperature ratings on the sidewall. From what I understand, the higher the Treadwear rating, the longer the tire will last, so therefore it should be the hardest rubber compound and lowest rolling resistance? Would the tire with the lower Traction rating also be the better choice for LLR, as worse traction would mean lower resistance? Can anyone shed some light on which rating will affect rolling resistance the most? Thanks.
