265/40/18 on C55?
Will 265/40/18 work on a 2005 C55? From what I've searched it looks like 265/35 is preferable. Any validity to that or would I have any problems? I would like to keep the tire a little taller if possible.
I'm looking at the Hancook Ventus for a good tire that won't break the bank. Anyone have any other opinions?

Search up a tire calculator online. You will be able to see the difference in height between the two sidewalls. I think 265/35 would work better. I have 255/35 and that's been great for me. 265/35 would be even taller so... check it out.

Hankook all the way. I've had them on everything from a 5-series to an MX-5. The way these C55s go through tires, there is no shame in getting a great value tire. Let us know how the 265s worked out!

I've consistently hear great things about Continental Extreme Contact DW's. They aren't too pricey either and come with 11/32" inch of tread which is more that most tires.

a 265/35 is not taller than a 255/35...265mm is the width while 35mm is the tire height...and as far as I know a 265 is pushing the limits of the OEM rim as I am running 265 on my 9.5" rear TSW...any wider and I'd be worried about rubbing...if you can get a 265 to fit on the OEM let us know cuz i'd love to have a wider tire without buying new rims...plus it'll help protect the rims a bit more

also got to be careful, if you change the width and the height its gonna affect your speedometer quickly...one size difference can cause your speedometer to read 3-4mph slower than your actually speed!

Correct, the 35 is the aspect ratio expressed as a percentage of the tread width, 265mm in this case. The 35 has a shorter sidewall than the 40.

lol but thats pretty much exactly what I said...the 40 is gonna be taller than a 35 and 265 is directly related to the width of the tire! so ya ok 35 doesn't exaclty mean 35mm tall but it does mean its smaller than a 40 which is all i was trying to say! lol

I just put 265/35/18 Pilot Super Sports on my C55 and since Michelines are a smidge wider than the Hankooks in the same size that came off, they've rubbed with a trunk full of stuff, my 2 daughters in the back and at full squat over big dips in the highway. Granted, they've barely rubbed for a split-second twice and only left marks, not actually digging into the tread, but rubbage did occur. I'd guess the Michelines are ~ 1/2" wider overall than the Hankooks were as they were flush with the side of the wheels while the Michelines have some extra width to them. 
The Michelines seem to ride better (softer on initial hits like expansion joints) and are easily stickier than the Hankooks, but that may not be a fair comparison as the Hankooks were old and felt "greasy" almost all of the time at all temps..
FYI, the fronts are 245/40's and again, the Michelines are slightly wider than the Hankooks and seems to be at maximum limits of clearance in all respects. I don't see any bigger tires fitting a C55 w/o fender "massaging" happening.

wow so your rolling 245/40 up front and 265/35 rears on stock rims...didnt know the rim could even handle a 265...im running the goodyear assymetric 2 right now only cuz they were brand new when i bought the car...when these run out in like 30k miles or w/e (assuming I havent put on wider rims by then) i'll move to 245 and 255 to prevent rubbing but get a bit more tire on the road!
