Ed PPruss I like your observation on "undernourished" tires !! Friends took 10.00x20 lug type rims and welded in centers that looked good and ran a long time.My 51 6400 came with 90% rubber on 3 piece wheels so haven't been into those yet. I saw where rain was blowing in the shed getting those wet,kinda wonder if they are rusting from the inside out ??
