Putting new rear tires and tubes on my John Deere "B". The tube was showing thru so I decided its time. Good used ones seem to be nonexistent. Decided on Firestone traction field and road. Its a working tractor and spends a lot of time outside so I wanted something that wouldn't weather check right away. I've replaced tires before but always used ones. Wonder if anyone has any words of wisdom to make the job better. Have the cast wheels and don't plan to put fluid in unless I find I need to for traction. The old ones had some fluid in and had no leaking. I'm going to inspect the wheels for burs or anything that might cause a problem. Will wire wheel any rust and paint with rustoleum. What does everyone recommend for lube and such. Thought about grease on the wheel where the bead is to prevent rust from moisture due to being outside but that might be bad for the rubber. Want to get the max life out of them. Thanks for any help.
