7" Heavy Duty Solid Wheelchair Replacement Wheels - Quiet, Non-Slip Front Wheels for Mobility Chairs (Ideal for Indoor/Outdoor Use on Smooth Surfaces & Uneven Terrain)

My GeoCruiser was shipped with the wrong wheels; seller and Distributor refused to correct the error. I found and ordered two of these wheels to solve a number of problems caused by wrong wheels. These 7-inch diameter wheelchair wheels with 8mm center hub diameter fit perfectly and ran smoother than the original factory wheels. These proper (7'' O.D.) sized wheels instantly, permanently cured at least 5 to 6 major problems that plagued the GeoCruiser for at least a year! They are solid yet resilient to surface irregularities. They fit the typical wheelchair coaster wheel axle diameter perfectly, rotated freely and smoothly. Their width was perfect for frame clearance (typ. 2'' wide) and spun without rubbing on the coaster frame sides. In addition, the tread on these wheels allowed the swivel coaster wheel frame to swing much easier to meet changes in direction. TIPS: READ or MEASURE your wheelchair coaster tire SPECIFICATIONS or DIMENSIONS precisely... Multiple Times... BEFORE you order. You need a minimum of:1__OUTSIDE DIAMETER (O.D.), across outermost tread surfaces of tire;2__INSIDE DIAMETER (I.D.), the size of Axle hole in the center of the wheel;3__HUB WIDTH, length of axle hole in wheel center at its widest point; and4__ TREAD WIDTH, thickness of tire at widest point of rubber wheel.Also note that Wheelchair Wheels are NOT the same as Walker Wheels, and NOT interchangeable.
