In regard to continental tires.the wheels crack at the slightest resistance. the wheels constantly need air placed in them sometimes twice a week. in a year i have had to replace 12 tires due to cracking at the slightest impact. the wheels do not last 50 miles after being flat they are destroyed the minute they hit impact. these are dangerous tires for anyone and these need to be recalled.
