If you're getting the tractor to mow with, the R14's will be a lot easier on your turf than Ag tires or R4's. If you're going to be plowing and gardening with it, then you'll be better off with a good ag tire. If you're going to run around on pavement some, then the R4's will probably hold up better with the fatter lugs. I really cannot see me wearing out a set of R14's. I don't plan on doing burn-out competitions or wheelies through the neighborhood, so they'll last me a VERY long time.
Puncture resistance? Hmm, wish I had a picture of something I found while box-blading in my back yard yesterday. It was the neck of a glass gallon jug of some sort, lifting ring still intact, and razor sharp. Not particularly old because it was definitely a screw top jug. There's no way I didn't run over it, but I can't find where it did any damage. I'll take a photo tomorrow. I know exactly where it's laying. The more I scratch around and dig on this lot, the more I'm convinced it was once the county landfill. There's no guessing what I'll dig up next. I've probably picked up at least 100 golf balls, a "you'll shoot your eye out, Kid" Red Rider BB gun, untold murdered and mutilated dolls, unidentifiable toys other than that they have plastic wheels. Rocks the size of footballs, boot heels, tennis shoe soles, you name it. I'm pretty sure we found what was ladies' lingerie, but it was difficult to tell what it might have been. We pick up at least 100 pounds of broken glass each year. Nothing I find here surprises me now. I just wish I could help Rick and Marty Lagina with a find that's related to the Oak Island Mystery. I haven't found a single Top Pocket Bobby Dazzler, though. Just rubbish. I'm sure I'm getting close to the Money Pit, though.
