Today remounted a front tire on my Farmall 460. Been leaking at the bead, tubeless of course. Went to the farm supply in town, found a new in the box inner tube for the 11L x 15, flotation type tire. Had previously removed the tire, cleaned and painted the rim, but the tire was hard enough to not seal evidently. Anyways, got home, slid the tube in, right from the box, I usually inflate them first to get the kinks out. Wrestled the tire back on. Been doing this since the 60s so did not pinch the tube, before you ask. Started inflation and BLAM, I thought the inner bead seated. Nope, wouldnt take any more air. Pulled out the tube, eight inch long split. Back to town, 10 miles each way. Found it was a too small tube, misboxed. The next tube had a clearer size stamping, and much bigger. Put it on, inflated it, all good. Tried to put it on, wide front axle. Hydraulic jack bled down, wouldnt go up that last inch. Walk to the barn, get arm load of wood blocks, block it, rejack it. Done, finally.
