We put around 350 miles on the tires with prerunning included. No flats at all. All the teams quads are running Obor now and we love them, from the traction to sliding to power to the ground. We highly recommend this tires if you're serious about your racing program. These tires are Baja proven Update:7/8/21: Just installed the tires and compared them to the previous tires i used to race with GPS Gravity. As you can see the Obor are taller and have more aggressive pattern. Now the GPS have been Baja tested. I did 1184 on a set at the 50th Baja 1000. No punctures. Now ill be testing the Obor next week at the 2nd largest Rally in Mexico, Coahuila 1000. Keep you guys posted. This is my 1st set of Obor tires, and so far they look great. Very good design and looks like a solid manufacturing. Ill be testing them in the 2nd largest rally in Mexico in july.
