(this is the abbv. Version of original 4091 character complete description.) 06/30/2006, fort smith Arkansas. Vehicle: 2006 Honda Ridgeline. Complaint re: Oem tires: Michelin tires (P245 65 R17 105S ltx M/S radial X)while negotiating a curve on garrison ave. Before 13th street, in the inner lane (4 lane road), traveling appx. 25-30 mph, was crowded into the curb by a car in left hand lane. There was not a hard impact, as the truck was roughly parallel to the curb. I felt the right side of the truck start to "climb up" on the curb. Immediately flattened both tires on the right side. Maintained control, & pulled off in parking lot. Both tires had "U-shaped flaps" ripped in the sidewall. Omitted exact description of the "rips" to reduce character count, but it's available on request. It was night, but I looked at the curb & road for any sharp objects that would explain the damage to the sidewalls & found nothing. Next day, I examined the curb & vicinity closely. I took photos of the tires, the curb, & vicinity. There was nothing that would have obviously caused the damage. I believe the tires blew out due to low speed contact with the curb. I believe the tire sidewalls are insufficient in design & construct for use on this truck, & that the tire sidewalls collapsed significantly when they came in contact with the curb, despite the fact that they did not sustain a direct impact. (all 4 tires fully inflated: Truck was only 4 months old & the tires had < 5000 miles on them). I believe the collapse of the sidewall caused it to be "pinched" by the rim, & due to substandard sidewall construct, it was followed but a sudden & catastrophic rip (blow out) up the sidewall. I still have the two tires. These tires were manufactured for oem placement on a 4 wheel drive truck, but failed to withstand a minor brush with a curb on a city street. I believe these tires are inferior in design, defective in construct, & sub-standard for the application.
