I have a yanmar 2420D that currently has 11.2-24 tires on the rear and 7-14 tires on the front. When doing a search I read that my tractor should have 6-14s on the front instead of the 7-14s (this is how I got it) I just ordered 7-14 since that is on there now and wanted to know it that's okay. I don't quit understand tractor sizing and number. I am under the impression that a 7-14 is just wider that a 6-14 but I'm not sure after more reading lol. Also my tractor is a 4wd model. Thanks for any help.
