I believe you should look for 245/35r20 for 20" rims - that is what I have on my SS. I was also told you could go for 255/35r20 but I needed wider rims. Also my rims 20" HPD's with the 5X115 (of course) with a +42 offset and no rub, and no clearance issues at all. I was told you could also use a +38 offset, but I don't know of any fitment issues.
