Yeah, I just have the stockys on for winter. You can run your wheels year around if there's no chrome or polished aluminum. Painted wheels won't corrode from salt, at least no quicker than a factory wheel would. If my wheels didn't have chrome they'd be on all year!

 

I have 22x9's on my F-150 and run a 305/45/22 and the tire fits the rim perfect.

not stretched at all and have had them in this size since 2004 with no issues at all

 

theres lots of Grand Cherokee wk2's running 305 40-22's. I had them on my 13 jeep SRt for a bit...but I wanted to lower it...so I changed to a 285-35-22 on 22x10's
