My dad has an old MF 65. The rear tires were shot from sitting and the wheels had typical corrosion at the valve stem. Several months ago we decided to get the tractor going so we put it up on Jack stands in the barn and took the rear tires off and repaired the rims. The tires were shot so I got rid of them but I didnt note the size beachside I thought it would be easier to find the size than it turns out to be. I bought some 11.2-28 online and when they were delivered they were definitely too small. So I returned them. Looking at tractordata.com it looks like there are a couple of sizes. I doubt a pair of 13.6-28 for $175. Id love to go with them for that price. Any insight would be appreciated.
