we bought two tractor tires. had the kid discing a field while I was at work and she turned too sharp and put the disc thru the tire, and of course with something that pulls for a living you can't have mismatched treads our you will tear up your transmission, so now I have 2 new tires that cost 2500 bucks and I have to figure out how to pay for them. may have to sell a couple of calfs early.
