There are a few members with both 19's and 20's vossen cvt's on here. Personally, I think 20's are too big. Either way, you can scope through the Build Thread to see what suspension, tires, etc. and if they are rubbing or not. Good luck with your decision and welcome.

I also think 20s are too big, I'm looking at 19x9 square all around because AWD. I'm thinking 19x9 with a 32mm offset should be fine in front.

If you're looking at CVTs with RS*R Down Springs you could go with either 19" or 20" but you would have to run 225/30/20 and 255/30/20 on the 20" wheels. I have CV5s with Down Springs and those specific tire specs and I have no issues rubbing but I could rub if I had gone with a bigger tire.

I have 20's on and I have the the same tire set up, 235/30/20 and 255/30/20 and I'm glad I got the 20's looks fresh just need suspension now, deciding whether to get coils or airrex.......😕

The wheel specs are (2) 20x9 +38
(2) 20x10 +45 , I thought it was gonna be a bad ride but cause of the width of the tires, I think the ride still rides like stock lol😃😄
