AW-189TCWMAPLE…Maple Tea Cart Wheel Sold by the Each. We suggest buying two so the wheels match. 8-Spoke Unfinished Maple Tea Cart Wheel…14 1/2 inches in diameter x 3/4″ thick …Hub is 2 inches in diameter x 3 inches thick. Includes tire. Tea Cart Wheels require special axle for attachment. You may use TCWAXLEPIN and make your own wooden axle or use the AW-189TCWAAXLE which has a fixed width and when the wheels are installed the distance from inside wheel side to wheel side is approximately 18-1/2″ wide, so if your cart is wider or narrower, you may want to use the TCWAXLEPIN to make your own. The TCWAXLEPIN is 4-3/8″ long of which 2-1/2″ should be sticking outside the wooden axle. Wheel pops on to either axle similar to the way a caster stem installs in the leg of a chair.
