If you have 5/10 on 7.25", look on late '50's farm trucks for when tubeless tires first came out. If you have 8 on 6.5", 19.5's are available aftermarket, some new trucks. Why would one want 20's on rear?

Strange that they only make the Super Traxion tires for the rear in 17.5 inch. At least they have the Super Transport in the right size. | | | | | Joined: Oct 2019 Posts: 238 'Bolter | | 'Bolter Joined: Oct 2019 Posts: 238 | Nebraska tire carries several types of 20 inch tires | | |
