Over the weekend on Market Place. Two are 25x11x12, two are 25x10x12 OTR 440 Mag Off Road. Their in great shape no holes & no plugs. Got them for $100. he was asking $125. I have a Sears SS15 that has 10" wheels might try them on that first. I've been wanting to convert my Mtd990 from 15" to 12" wheels so I can try a pair of these on it. I'm not sure what to do on the fronts yet with these on the rear.
