Quote: How can you possibly hear tire noise on the hiway?!?
Tread design can do lot of noise rolling. Put your bike on the highway with a bit rough new asphalt at 60mph higher gear, a bit of throttle, and you can listen it. It's a noise like a transmission chain, but more padded.
Use a dirth bike with off road tires on flat asphalt...
I didn't write MT66 are s%it, I'm only saying it's a tire I've used sometimes and I don't like.
