20/22 Combo on s10 blazer..what size rubber?

Whats would be the best combo for tires. I was looking at anything from at 245/35/r20s up front, but I dont know what size 22's would work out back? I dont want a lower profile in the rear.

probally a 265/35/22.

is there such thing as a 245 or 255 35r22?

when you search google for 255/35/22
it brings up that some poeple are runnin this size toyo on some cars but the toyo site makes no mention of them anyone know what the deal is?
