Sumitomo HTR A/S P01 (H- or V-Speed Rated)
Follow-Up Review: 5,000 miles on tires
May 30, 2012
Previously, I noted winter MGP around 38. Now, it's spring; the engine auto-stops as long as the car is stationary with the heater off. Mileage: 44 in suburban, 35-45 mph stop and go traffic. Couldn't be happier with these tires, and pretty darn satisfied with the car using it this way. (No good on high speed hills.)
Initial Review: 3,500 miles on tires

These are follow-up comments to an earlier review when the tires were new. After 3500 miles, putting high performance M/S tires on a hybrid may seem illogical, but I am very pleased with the outcome. The original Dunlops were very small, LRR tires. The car handled terribly, showing heavy understeer, squealing, and minimal traction in all conditions. The new Sumitomo's completely removed the understeer and revealed a very nicely balanced chassis, although the low power and light weight of this car does not excatly tax the tires. Terrible wet cornering and wet traction were the worst problems, but these qualities have been completley eradicated by the Sumi's. My little Insight now corners with complete confidence and competence, wet or dry. Some say these tires are noisy, but I do not find that to be the case. In 3 of snow, the tires worked just fine. I beleive that gas mileage has been reduced 1 or 2 mpg, but it's hard to gage that in winter, because, when the heater is on, the Insight's autostop mode rarely goes into action at stop lights. In other words, gas mileage in this car is always worse in the winter. Now, it's getting aroud 38 mpg when it used to get 40. I am pretty sure that come spring, mileage will be back to normal. I recently inflated the tires to 40#, and did notice a slight improvement in mileage and no change in ride characteristics. These tires were a great choice.
