UMP modified tire issues

[Homey]

Has anyone experienced new tire failure with M30? Went to practice and mounted new rears. 13PSI right rear 10PSI left. 5 laps and right rear and tire exploded. Over a third of tire gone. Took out decking and quarter panel. Tires mounted only. Not buffed.

Thanks

We had problems with them earlier in the year. We found running a minimum of 15psi in the right rear, with a good hard buffing helped a lot. Youll find out that tire likes a lot more air pressure then the old As tire. I also let mine sit in the sun for around 4 hours after they are first mounted. The rubber is way to spongy when fresh. It seems like the M tire is better on night 2 than when new. Just keep it buffed.
