What size wheels?

[WojoMojo]

Sorry for asking probably a stupid question, but just wanted to be 100% sure. Looking for some rims to buy in the spring and just wanted to triple check size. From research it should be

20x8.5 5x114.3 40mm offset..

Is this good? Is there anything else I need to worry about as far as fitment? I'll just be running the 245-45-20 tires I already have on them.

These are what I'm looking at - TSW Rouge

my 2010 was non pp w/ 19",255/45/19 their offset was 38. shouldn't be an issue. but a site i used was
http://www.willtheyfit.com/
just to make sure. i upped to 20" 245/45/20. forgot what my new off setbut gave me more room.

Thanks for the website link! It'll just be 2mm closer to the strut at a 40mm offset. Unfortunately TSW doesn't have any rims with a 38mm offset, but I feel 40mm shouldn't be a problem, hopefully. If 2mm is going to throw it off that would be crazy
