The Accuride #28157, a 22.5" x 6.75" lists it's Bore size as 6.50 and the original #60130 said it was 6 15/32, are those close enough to be considered equivalent? Difference apparently being "1/32" of an inch.
What tires would you recommend for my truck that weighs ~ 8160lbs by itself, and a GVW of 16K, 2 Ton Dually Rear, if I were to run the Accuride #28157, a 22.5" x 6.75"?
