Do you guys recommend I go to a wider than stock tire on the MR BBS wheels for street driving? I have a Whiteline 24mm adjustable rear anti-sway bar and Tein S-Tech springs.

 

No reason to for street driving but the only thing it will hurt is your mileage because it will add some weight.

 

If you don't track/autox your car, there would be little benefit other than some added traction for any spirited driving. It will help lighten your wallet though! j/k

 

I run 255/45 tires on the stock IX wheels...no rubbing unless I'm doing a full lock turn around and it's only for a split second.

Only reason I got the tires was because I paid 250 for a brand new set when the stock Advan's ran dull.

So I'd say no problems, go for it!
