Holy crap this thing sucks in the snow

So after the devastating inch of snow we got yesterday in Maryland, I am sold on getting winter tires. I have a 2007 335 with sports package and 18" OEM 162's. Would it be better to just get winter tires and have them mounted and dismounted every year, or go with a dedicated winter wheel/tire set up?

Would I have any problems with speedometer accuracy, or alignment going from 18's to 17's? How much better is the grip on 17's as opposed to 18's? Thanks for the help.

just get a winter set......ive picked up 3 sets in the last 3 months, yea i know, rangign from OEM 17" to ASA 18" all with blizzacks, all with what i would call 90% tred.
the OEM i paid $650, the ASA 18" (they are m3 fitment also) were $450.
i also had a set of OZ racing wheels with blizzacks but the tred wasnt up to my liking for $300.
so its not worth it to mount and dismount
check ebay and craigslist

speedo should be pretty accurate, its only when you go 19+ its a noticeable difference.

grip isnt much of size but 17" is a more popular winter tire with a square set up. Rims the same width and tires the same width/height.

No alignment is needed for most application.

Changing from 18 to 17 should not change (by much) the rolling diameter, as you'll use a larger sidewall to compensate. Use the compute app on the top of this page to find a 17 application that works within 1% in diameter change.

You cannot use 16' wheels on a 335i, but most 17 inch wheels should fit. Get a set of cheap 17x7.5 and install 215 or 205 winter tires. You have to be careful that brake actually fit within the wheel, they are quite big.

narrower the tire, the higher the grip and less chance for hydroplaning in the slush.

definitely go with 17" smallest/narrowest setup you can fit.

Thanks for the help. I guess I will go with a dedicated 17" wheel/tire combo.

Word. As mentioned, check craigslist. Sonic Tuning had some nice winter packages a short while back too; check the sponsors section. Either that or Tire Rack.

I've been very pleased so far with my Pirelli Sottozero winter tires. I'm running 225s at all four corners on OEM 162 wheels. We'd had three good snow falls so far this year in Detroit, and the car has done very well (I have a 335i).

Winter tires are a must on these cars. With 50/50 balance they are great with snows. 225/45/17 works well on dry and wet icy roads. I have Blizzak LM-25 and love them.

That's what I am going with. Everyone else in the mid Atlantic . . . You are welcome. I just guaranteed that there will be no more snow this winter!
