You're right, it was a typo. 255/30R22. The outside of the tire rubbed right near some of the plastic venting in the liner. The offset was +30, I think. It was almost too much but did take the wheels all the way to the outside, nearly even. Expect your efficiency to drop like a stone. I lost like 20% effective range with them installed. I bought a separate set of TPMS sensors for my 22s so that I could swap the 19s back on for taking trips. In fact, because I saved the 19s, I was able to keep the 22s when I sold my P90D. I'm going to put them on my P100D this weekend. I'll take a pic on Sunday and put it here.
