Want to get wider 17" tires, need help.
Hi all,
I'm a first time BMW owner. Just recently got a 2011 335i Xdrive w/ 17" wheels (Type 160) that came with Conti RFT's 225/45. I gotta dump these RFT's. Is it possible to get wider tires for these 17" wheels? What's a good tire size to upgrade to? I'm also considering getting Pilot Sport A/S 3 for spring/summer/fall and then a set of winter tires for the Chicago winters. Thanks for any help you guys can give. Tom |

Those wheels are 8" wide so you could definitely go 235/45R17 (slightly taller sidewall) or most likely also 245/40R17 (slightly shorter sidewall).

I had the exact question a few days ago but no response. Bimmer74, switching to 235 results in a 1.399% difference based on the offset calculator, and switching to 245/40 results in -1.0% difference. Are those percentage differences so small that they are irrelevant fitment wise?

235/45R17 will definitely work without issues. A good number of members here go from 225/40R18 to 235/40R18 which is a similar overall wheel/tire diameter increase and I don't see why it wouldn't work on the 17" wheel. The 245/40R17 should work too but I am not sure I would go for that personally. The tire is quite wide for an 8" wheel so it will create a bit of a bulge which will increase the tire's tendency to roll during hard cornering.
