I have a brand new l3901 and am attempting to load the rear tires with windshield washer fluid. I put the back on jack stands but once I let the air out they pull off the bead. Any ideas? They're r14 hybrid tires.
Yeah, sometimes. About the only thing I’ve ever gotten to work is have the air/water adapter within reach, inflate tire to max pressure, pull the valve stem, and get the air water adapter threaded on as fast as you can. Once your air/water adapter has the valve stem sealed again, you can bleed off more air as needed as you’re pumping the windshield washer fluid in but just don’t bleed the air to the point it can come off the rim. You probably know what you’re doing but in case not so much the below is a short practical on how it’s done. Yes, the background music is insufferable, but mercifully short. Don’t know why some people feel obligated to use background music on something like tractor tire ballasting videos.
Your tires are too new and haven't relaxed since they were stacked after being produced. Just be glad that you didn't have to be the one to mount them on the rim. The factories have special machinery to push the outer tread to force the beads to seat on the rim.
Set the valve at 12 O'Clock, and fill to the specification on the tire. Check it periodically to make sure that it is at the proper inflation. You don't want that tire to blow off the rim due to low pressure.
