Are 17 inch wheels OK to use with snow tires
you can get excellent snow-tires in a size that will fit your wheels perfectly, but remember that narrower is better. I would definitely call the tirerack, www.tirerack.com
good luck!
I want to get a set of AMG monoblock staggered 17x7.5 front and 17x8.5 rear for non-winter. I want to use my current C7 (17x7.5) wheels with snow tires mounted for the winter. Are the C7's too impractical for snow or not?
I was wondering if the AMG Monoblocks are any heavier than the C7 wheel. To be honest it looks like the C7 is lighter(more space between metal). Here is a pic of the AMG wheel - it looks like it has much more mass.
If will be getting new Michelin Pilot Sport A/S rubber for the AMG's. The Contisports I have now should be as Bald as Hank Kingsley(Larry Sanders Show) come winter time. After 6k miles I have 6/32's thread left. I have never owned a pure summer tire before, and never will again, its just not worth the fuss of yearly replacement to me.
I hope others that are considering the C7 option read your comments. To only get 6K miles out of a set of tires is going to be a very expensive option in the long run.

D - per www.wheelweights.net, the 7.5's are 27.5 lbs, and the 8.5's are 28. Luke at Tirerack would be able to verify that, if you want (don't know the accuracy of that website's numbers). I did do the bathroom scale +/- 10 lbs weighing, and the C7 with tire was 44 lbs, though I have no idea how much a 17" tire would weigh. Don't forget that weights are about more than the appearance on the outside, so guessing based on appearance is about as accurate as my bathroom scale.
As das (nice to see him post something that's not BMW-related) said, if you get good winter tires, the stock C7's would be fine, but 16's would be better. You might want to look at selling the C7s and picking up some steelies, but the C7s won't kill ya in the snow.

12-15k is not long enough for me, thats why I am choosing the Michelin A/S - which should give me 25-30k, plus they are so much quieter than the Conti's(loudest tire I have ever driven).
Thank for the website reference Tommy! Very useful.
Well, Viper, you do realize that there are other tires out there that wear better? Though I have about 7k on mine (Contisport) and they're still fine. Don't know what dmichael was doing with his tires, but his wear sounds excessive.

DrMichael: I just had me a look at the Mich A/S's you're planning on using for winter- I wouldn't. I obviously don't speak from experience on this tire, but I can tell that this tire was clearly developed with a performance bias and don't think snow/ice traction will be at all acceptable in Mass. If you're going to switch wheels for winter, get something that was designed for inclement weather first and performance second like the Dunlop Winter Sports or Mich Pilot Alpins the NRWs. My .02.
If you didn't like those tires at delivery, you should have told your dealer to put something else on -- I have and they have changed tires before delivery.
I have found the Michelin Pilots to be quiet if not lasting for more than 20k miles and fine as a daily driver - of course, one needs to avoid construction sites or you might find little treasures (nails and screws) in all your tread.
If you want less sporty in a daily driver, try a Michelin MXV4 -- which lasts forever and is quiet -- or a Pirelli P6000 or somesuch.
For snow, from a much earlier read in Car and Driver, the thought was the skinnier the tire, the better the performance in the snow -- evidently, you don't want a big patch in the snow. Get some smaller steel wheels and snows to use for the 4-5 months you may need them -- protect those alloys for the spring, summer, fall.
Very unenlightened to buy replacement tires from your dealer! I personally can't see how MB is making "a lot" of money on it. Considering all the inclusives how can anyone say this factory upgrade is not a genuine bargain.
What I do object to are items like a $900 CD changer . . and a stereo system that should be better for the cost, and power seats that cost $1,300, and a COmmand Sytem that is $2k and a telephone system that is another $2k.
Compared to those, that C7 is a deal.
From what I found out from my purchasing agent friend at MB they pay $12 more per wheel and $9 more per C7 tire over the base package. The painted handles cost $3 per set additional and the fancy pedals cost $11 over the base. The lack of a resonator on the exhaust cost -$14. Short throw shifter comes in at an extra $27. Leather trimmed wheel and shifter an additional $16. The evolution mats cost the same as the base mats. When you do the math you will see that it adds up to $116 cost for a $750 option. Don't you know that option prices make major profit for the manufacturer ? Yep this upgrade is a genuine bargain like you say.
Whatever it costs MB, it makes the coupe at least 750 cooler/nicer IMO and that's what really matters. Sounds like someone's just ticked that he didn't get it.

Read my previous posts. I did get it. I am just not happy with it after having to shell out extra time, effort and money to buy snow tires just to cope with the winter season. And then have to change the tires back after the season. Then find out they wear out way too fast with a little spiritied driving. If you read my posts and actually thought about how consistent my remarks have been maybe you would understand. What I am trying to do is really spread the truth about this option especially to the newbies that are asking for opinions on these options. If you live in a sunshine state and can use the tires year round then good for you maybe the option is perfect for you. But it may not be the best choice for all and when some of us rave about it I really believe that it may mislead some readers into getting an option that may not be in their best interests long term. And you know you cannot rely on the sales monkeys for this.

Everyone's gotta decide for themselves what's right for them, maybe you would have faired better if this site was your secondary source of info rather than the primary, but I've been involved in many a C7 debate here and I don't remember anyone saying that you could leave the tires on all year for us Northerners or that the tires wear as long as the standards because that would be, well just plain silly.
