VX-10 Zenkai BRAND NEW! The VX-10 comes with an all new compound. 70/100 x19 42M IRC Tire concluded that the compounds used for the large wheel sizes are not the best choice for the young generation. Our engineers developed the compound to improve durability, stability and performance for small wheel sizes. For aggressive large-tire performance with a smaller circumference, we optimized the number of knobs on the shoulders and center of the tires, also adjusting the height and angles of the knobs within the tread pattern to completely re-design the tire.This creates more straight traction as well as braking traction with excellent handling.INCLUDES 1 TIRE IRC No. SIZE TYPE L.I.
