Just bought a A-C D14 with one good rear tire, and one well worn. The D14 takes 12X26 rears, which I understand is somehow the same as 13.6X16 in modern terms.
Ok, so far so good - There is a 13X26 tire for sale used on craigslist for $75 here. Seems like a perfect deal if it would fit, but I'm unsure about how big a deal the missing 0.6 width is - I understand that tractor rears are somewhat flexible on width but I'd hate to waste money in an attempt to save money! Any advice?
