There are tire size charts that show tread width and loaded radius, several of the tire dealers go to the Rubber Manufacturs Association that lists target dimentions and rim sizes.
IIRC 8R19.5 has the dia, weight capacity and is skinnier.
Sipeing with a 3/8 repeating pattern is good on snowpack, self cleaning blocks on fresh snow and for Ice the retreads with inclusions in the tread work well. This combination is not on the market, the closest is HiTek retreads ( I think they moved from Denver to South Dakota)
Tire sizes are currently mostly sectional width ( sidewall to sidewall ) times aspect ratio ( the second number with a decimal point ) plus 1/2 the rim diameter for rolling radius. Tires are metric and rims usually inch measurement.
