Thisis one (1) 18x 1-3/8 Turn 3 Racing Micro Mini BMX race tire. This tire fits 18 x 1″ (400mm) rims and inflates to 55psi. It will work on most stock Haro and Redline Micro Mini race bikes; it will not clear the fork on a DK Micro.The total height of the tire is approximately 18-3/4″.

This tire uses 18 x 1-3/8 (400mm x 37C),20 x 1.0-1.5 (406 mm x 25-38C),20 x 1.25-1.5 (406 mm x 32-37C) or 20 x 1.35-1.5 (406mm x 37-47)tubes. We do not recommend using 18×1 tubes in them.

Note: Due to the tire having a taller profile than a stock 18 x 1″ tire, it may not fit some frames & forks.
