    Dunlop Roadsmart Sportmax blister

    Riding down PCH yesterday at a slow pace enjoying the cool weather and the nearby ocean breeze. Slowed down going into San Clemente and when I got to about 5 MPH approaching a stop light, the front started bouncing up and down at regular intervals.

    Parked the bike and found a "blister" sticking out along the center line of the front tire. The damn thing measures @ 1" high x 2" wide X 12" long!

    I hate to think what would have happened if this had occurred at high speed like on last week-ends run to Big Bear.

    TPMS read 45.5psi at the time. 46.5psi rear. Front was @ 41.5psi, rear @ 42psi when I left the garage.

    I dropped the pressure to 32psi and limped home.

    @ 6000 miles on this tire with plenty of meat left. I took some pictures with my cell phone, I'll see if I can figure out how to insert them later. right now I'm going to take the Harley fro a ride up the coast.

    Considering the hand full of riders here who have experienced this, I am amazed that Dunlop's doors are still open. Junk!

    I've hated every set of Dunflops I've ever owned. And I'm not a fan of Bridgestone either after I tried a set of 021s.

    I just put the Michelin PR2s on the ST.

    I just replaced my front Roadsmart. I really liked the tire. Handled great and I got 12K miles out of it (I've been running Z6's and getting 8-9K). But with all the defects being reported I won't be putting on another.

    Glad to hear it wasnt a major problem at speed...but this is not a minor issue by any means. Not a fan of Dunflops...junk 'em after documenting it and sending it to Dunlop...what garbage.

    Wow, glad you found the tire failure before it led to a much bigger problem!

    I speculate that once a delamination occurs, the blister grows very quickly. There's a lot of shear force put into the tire through the tread in cornering and braking, and I'd think a blemish once started would grow quickly. JMO.

    Dang, you're one lucky dude.
    To many reports about problems with this tire. I'd never go near a Roadsmart tire.
    Enjoy the cool ocean breezes today!
