winter tire for 2012 C350 4MATIC
(1) My OEM is R18 for my all season tires (staggered). Would R17 for all 4 tires be adequate or do I need R18?
(2) Would I need TPMS installed in the winter tires?
(3) Can someone explain what the "MO" & "TL" mean (see attached chart)?
Thank you in advance.

2) TPMS is not required, but highly advisable. With wintertime temp drops, and associated reduction in tire pressure, it is helpful to have the warning. Further, in the absence, you will have an error message all winter long.
3) Sorry, don't know.
4) Those are fair, but not great winter tires. They are in an odd category known as "performance winter". My theory is that in the winter, the best snow performance is needed, not a worst-of-both-worlds attempt at a blend. I would look for "studless winter" which are much better at snow and ice, although not as strong on "performance". I suggest Blizzak WS70. You can order a package from tirerack.com, tires mounted/balanced on wheels, with TPMS installed, and shipped directly to an approved installer near you. It's then just a matter of lift the car and work the lug nuts and you're done.

Thank you very much for your useful info.
I've seen your responses previously to other users and have always valued your opinion. And now, thank you for responding to a question of my own.

Sorry I didn't indicate my location earlier on, but now I have updated my profile.
I'm from Toronto, Ontario. My local dealer quoted me CDN $2472 + tax. It's higher than the ones I see from you link for U.S. customers. It appears to be the only package they offer for my vehicle at the moment.

This has got to be a better starting point, even with shipping and taxes!?!?
They don't list the Canada only 350 4MATIC, so it shows 300 4MATIC, but that does not matter for this application. Worst case, find one of their local installers in Buffalo/Niagara Falls who also has customer storage to save on international shipping and your higher tax rate. Swap out your tires on a nice drive for some great authentic chicken wings twice a year and drive home smiling!

by the way, I have the rims up for sale, I got rid of the car, the tires went to another vehicle, and rims are just sitting in the garage







Using 16" wheels and 215/55-16 tires is a great idea if it fits with the brakes on a 350. It will actually improve your snow tire performance, as the same weight car is now riding on a smaller contact patch, so traction improves further than with a wider 225 series. If you guys can make a good deal on the wheels considering what new ones cost, this is a WIN-WIN for both of you. Then just have the Blizzaks shipped from tirerack to a local installer, bring the used rims, and you'll be set.
I had no issues with this setup at all, I almost looked forward to the snowfall.....LOL

But it's still amazing 16's fit on a 2009 C350 W204 model. The US spec for 2009 front rotor dia is 11.6" for C300's, and 13.4" for C350's.
I called TireRack about 16's for a 2008 C300, and they flatly said 16's will not fit. I ordered one anyways (for a spare) and it fit, but only had .21" clearance to the outer caliper surface.
Could be the C350 uses an ultra slim caliper to offset the .9" greater disc radius, vs a C300. As Sportstick said, could also be a special Canadian vs of the C350.
Could also be a 16" wheel with at least 20mm less offest, to move the smallest wheel ID (near the spokes) out and away from the caliper. Bottom line, all 16" wheels will not fit.
GateKeeper, what wheels are those (early Mercedes?), and what is the width and offset? ... thanx

5-112 16x7 ET40 T504 HP (Bright Silver)
and yes there is not a lot of clearance between rim and caliper, but there is as you can see in pic3

They are just an alloy rim, the center cap has the MB Logo, but it can be anything you wanted
I don't think there is a US vs Canadian version, I am sure all the parts would be similar, options not so much, but changing break calipers don't seem cost effective
If needed I can get more info, from the place I purchased them from if need be, there are other numbers and such stamped on the backside of the rim as well

What stands out in the pic is the location, between outer rim edges, of the "tire mounting recess" which is the location where the main, 16" cylindrical wheel part has the smallest ID, at the recess, as I had previously posted.
I have 2 different 16" wheels in house, and both had the smallest wheel ID near the outer bead (just inboard of the spokes). The 16x7x46mm "spare tire-wheel" from TireRack for the 2008 C300, was the same way, with .2" clearance from that small ID to the Caliper.
Your wheel seems to have that wheel "dip" further in, almost beyond where the caliper sits. It would really help if you can get some pics of the wheel w/o tires, at diff angles, to show the dip from 16" location. I now think there is another type of wheel with the dip/recess at the inboard side, vs the outboard side.
IAlso, if possible, get a rough esimate of the disc dia, vs my stated 13.4"

If you cannot make anything out, let me know, I will type up the numbers in a post instead, hopefully this helps you out...

The rim shape is not unusual, as I had wrongly suggested

I think those are light, oem MB rims. The caliper is right at the tightest fit location along the wheel ... it seems this is a common feature for most 1-piece aluminum wheels. I can only assume the C350 has a more compact caliper design vs the C300, that offsets the larger diameter rim.
Thanks again for the pics.
