Those are Dick Cepek, Fun County II, Kevlar reinfoced radials - good for floating on the snow / ice.
Size is difficult to tell, but I think they are 38's

Oh the tires on that 90 are not Fun Country II, sorry I didn't mention that earlier they are just the Radial FC, which is what only comes in sizes up to 37"
The Kevlar fun country's do come in sizes all the way up to 44", which is usally what is seen used.
