I had a tire on the front of the Oliver 1600 that was going soft and had to be pumped up about every three days or so. The weather was outstanding yesterday,so late afternoon I got around to taking it off and fixing it. I figured instead of looking for a hole as tiny as that one must be I'd just put a new one in it. I had some new ones here in the shop anyway. I put it in,put it back in the toolshed and went to feed with the 1365. It wasn't 15 minutes I was driving past the toolshed and heard a loud PSSSSSSSSS. I looked quick and that blasted tire went flat in about three seconds. I took it back off this morning and the tube was split right at a seam. I got lucky and found the little bitty hole in the old one and patched it. What a waste of time! Somebody had warned about those Hi Run tubes on here before,I can testify to what a waste of money they are now.
