I am currently riding a 2018 Yamaha MT07 with Dunlop Q3+ size 180/55/17 rear and 120/70/17 front. I ride both track and street and use 33F/36R psi for street and 30F/30R psi for track. I am running the correct tire pressure per manufactures recommendation. The last three sets of tires I've owned have had a tear right through the middle of the rear tire. It's always only one tear and the set I have right now has a tear and the tires where just installed 5 days ago. What could be causing this tear? I've attached pictures of my previous two sets of rear tires.
