Nice work. This looks like a good idea for tractor tires. They’re very expensive and this could be significant savings without sacrificing safety Retreading a tractor tire or tires for other slow moving vehicles isn’t a bad idea! Retreads on cars/truck/semi trucks is a bad idea they are junk and fall apart Never give an old tyre a second life like this. This has killed so many people in burst tyre road car accidents especially when its very hot on the paved roads
