IAA-C63

I have an '11 C63 sedan with the stock 18" wheels, no performance package. I searched Tire Rack for winter tires and nothing seems available in this size. Any suggestions?

I posted a similar question earlier last month, but didn't get a response. Here is what I ended up with.

Hakka R2's video clip

F: 235x40x18 (18x8)
R: 245x40x18 (18x9)

The rear size wasn't ideal but given the 10mm difference (5mm each side) I hardly think the deflection or angle flex of the sidewall will hinder the tires performance or longevity.

i use the oem 18s as well for the winter

ws70s are great.

245/40/18 is 2.8% bigger overall diameter than 255/35/18, which I think should be OK. Hopefully, it won't confuse the ABS.


How are the WS70 on dry winter roads in terms of feel, noise, grip, etc.? And how do they cope with warmer winter temps, say up to 60 F?

I noticed that going with 245/40/18 all around opens up more options for winter tires:

It also increases the overall diameter of the front by 1.2%, versus 2.8% rear, so the delta is reduced to 1.6% which should be better as far as ABS working properly.

So far the noise is nothing louder than the Pilot Super Sports i had on prior, Car still handles well. I'm not taking corners like I do in warmer months. I bought from TireRack and would HIGHLY reccomend them, i picked up 18X8 MSW rims and 245/40R18 WS70's mounted, balanced, and shipped for $1400. My E55 does not have TPS so being able to swap was my goal, I have not hit the brakes hard enough to engage ABS but will try that this week and report back.

This was well worth it in my opinion. Here are some more pictures of the rims prior to the arctic blast we got going here in CO.
