i've tried both, the american racing and junior dragster. they both hook up well, hot or cold day. the jr. dragster tire is about 2 lbs. lighter.so i would definately reccommend M/T. a good place to get them is Motivational Tubing,because they will sell you a matched set. which makes a big difference at the big end of the track because of the swell.
