Review on AR PRO 5 00 6 Replacement Straight 2 Pack by Brian Douglas

Best deal on 4 of these I could find and they are easy to install and work well. No pops yet and I've put about 2 cubic yards of mud and rocks on the cart to make it appear stable. It is a pure "donut" - completely round in cross-section, like a bicycle inner tube. The old tubes in my wagon wheels were toroidal, more like a car tire, flatter on the outside. Because of this, pumping up the tube made the outer tire slightly "rounder" than its natural flat shape. So far this hasn't been a problem and the slightly reduced contact area doesn't seem to have a negative effect. However, if you are looking for an EXACT match for this type of tube, they are slightly different. (As a side note: the size markings are identical; there appears to be no shape marking.)
