This is a pair of transistor vtr 2WD front tires. The transistor tread is the new kid on the block with 1s and 0s for tread. The transistor provides good, consistent steering in a variety of conditions and is the first of pro-lines front vtr tires. The vtr tires and wheels introduce the horizontal mounting style common in 1:8 nitro and bring it to the precision environment of the 1:10 racing scene, resulting in the lightest tire/wheel package ever produced. The tire mounting surface has been increased from 2.2" to 2.4" giving the tire a lower profile sidewall and ultimately more traction. Test drivers immediately noticed the improved agility and traction that the vtr tires provide when combined with pro-lines vtr wheels. Get your own set of vtr transistors today!.
