I am needing to replace my tires. I have a 2000 Insight and one of the belts broke in my left front tire. They are OEM and have 43,000 miles on them so I will probably just replace all 4. I have read the threads regarding different replacement tires. I am debating between the OEM Potenzas and the Sumitomo HTR 200 which is also a highly rated tire for low resistance rolling. I want to maintain my current MPG as much as possible. I would be buying 185/60/14 in the Sumitomo. If the difference is small I may go with them, but I really need more info before I can decide. I would appreciate your help please. Of course any relevant and helpful info will also be appreciated. THanks!!
