One of my Sumitomo HTR H4 tires started delaminating (forming a blister) under the tread after about 70,000 miles on them, so I replaced them with Bridgestone Potenza RE92 165-60R14 on 14" rims at 65psi. Normally I can notice a distinct drop in coasting performance when going to a new set of tires, but so far these new tires are coasting as good as the well worn Sumitomos. It will be interesting to see how well they coast once they get broken in.
