Michelin Pilot Road 4 GT tyre blew going down freeway on my Honda ST1300PA Using recommended 42psi. I had checked tyre-pressure and oil-level before ride, both perfect. I did figure-8 in front of house to verify steering and wheel-bearings OK. First 10-minutes of ride went fine. Then I started hearing rhythmic sound like riding over washboard surface. Then I got rear-end weaving back & forth, so I pulled off. Halfway down off-ramp, I felt rim touch down from loss of pressure! I certainly didn't hit anything to cause even a single hole that large. And definitely not something 10x in row to cause that many holes. Regular spacing shows it's some sort of internal delamination of cords? Tyres have about 7-8k miles. Wear-bars shows I've got another 2-3k miles left. Bike has 19K-miles and on 2nd set of tyres. Everything was running perfectly with no problems until this happened. Damage looks like blood-packs used in movies, blowing from inside out.
