Anyone having trouble with inner tubes in TurfTiger 24-12-12 rear tires? I have been using Carlisle #321371 tubes with TR6 stems. The tube is a 22/23x8r 11/12 size. I have had some of other brands (same size) split after final inflation. I don't think they are getting pinched. Recent problem. Any ideas?
Thanks,
Knots
