I have an 08 Tacoma double cab 4 w d auto. I bought it last may with 86k miles.
Previous vehicle was a 95 Tacoma with 285 K miles and running great but I needed the full back seat room.
About Three month ago I bought a set of Michelin Xts tires as the originals were getting a bit thin. The new tires ride and feel great, but I can hear and feel (in the steering wheel) a slight hum/vibration , mostly at 45-50 mph on any smooth road surface, wet or dry. As I said it is "slight" but I am keenly sensantive to vibs.
My local Auto Tech has road tested it and thinks that it may be tire noise but he is not sure. Tire dealer says he has had no issues with these tires and has sold many sets over the past years. I had installed them on my 95 Taco and did not notice any "hum" and i know that the 2008 truck is quieter overall.
Thanks, Alpine bob
