Correct me if I'm wrong but I think he's more referring to tires on stock rims...he never officially says but he doesn't say otherwise and his sig has stock rims in it so i may be assuming too much

Accidental L8 apex

My info is relevant to his interests as I'm running the stock C55 wheels w/ 245/40's and 265/35's front to rear.

BTW, GPS says my speedo now reads 1mph low below 50mph and 2mph low above that due to the larger combos. Cruise on 49mph is actually 50mph and 78mph on cruise is really 80mph by a radar gun. Got a VA ticket on the way down to Outer Banks set on 79mph according to GPS and that's exactly what he told me after lighting me up.

And most state's tickets travel with you when you get home unless you're in Alaska either way. Yes, I checked and will pay my $132.00, "happily".

Sorry to revive an old thread but I've searched to within an inch of my life.

I'm about to fit 235/40/18 & 265/35/18 because the 225 and 255 are a little too stretched so I'm about to fir Pilot Sport 3's in the wider tyre. The current 225/255 Sumitomo htr ziii does not rub.

My rims are 18x8.5 ET33 and 18x9.5 ET35 AMG replica wheels. I'm mainly concerned about the rear as from what I've read the front 235 should be ok. The difference between the 255/35 and the 265/35 is 5mm radius and 5mm width either side. I was thinking maybe a #3/4 spring pad might give enough clearance if rubbing should occur.

I'm lowered on eibach and bilstein b8s

I see alot of ppl here are running 265/35/18 on a C55 successfully. I have a C32 and was wondering whether the same fitting works on it.

You will be able to fit 235/40 and 265/35 no problem with stock suspension (that's what I have right now). If you are lowered on 255 in the rear and no rubbing then you're a lot better off than me. If I take a really sharp right turn I'll get a very slight rubbing of the outer tire to fender, only on the left side. It did help a lot when I put the bigger H&R sway bars on so there was less body roll.

See if you can get your fenders pulled/rolled if you have any rubbing issues, but it should definitely fit.

What size rims did you say you have? They are wider than stock, correct?

C230 Mulac

Mine? They are 18x8.5 and 18x9.5. Stock are 18x7.5 and 18x8.5.

I'll probably switch to a lower width in the rear with higher offset so it sits further into the wheel well and won't rub on outer fender. Thinking an 18x9 with ET40 so I can still fit the 265 wide tire. The extra traction is nice

So you get the rubbing using 265s on stock c55 springs? What brand tyres are you using?

The stock suspension on the c32 is a fair bit higher than the c55. The eibach lowers the car to slightly less than the c55 stock from what I can see.

I'm thinking of going 235 front and keeping to 255 rear ... There's not a lot of fender to roll in the rear and I want to avoid cracked paint.

Still wondering whether 265 with a #4 spring pad would clear.

To calculate the overall diameter of any tire, without compensation for tread depth, use the following equation;

(Section width) X (0.aspect ratio) X 2
25.4 + Wheel diameter

= Overall Tire Diameter

Stock rear tire diameter would then look like this;

(245) X (0.35) X 2
25.4+18

= 24.75"

From there you can calculate overall diameter differences in inches and percentage between different sizes. Then you can take a tape to the car and see where the new tire would fit in relation to the fender.

OR you can just plug in all the tire sizes you want here http://www.1010tires.com/Tools/Tire-Size-Calculator

Compare stock up to four other sizes. Great tool.

FWIW, I run SL55 "Rotary" (sp?) wheels on my C55, 8.5" and 9.5" widths. The rear has Hankook Ventus with 255/35/18 on stock suspension. It has the perfect amount of stretch and increase in width over the stock 245/35 size. I'd like to try a 265/35 but thats just over half an inch taller than stock which could get tight on these cars, esp with the offset and width of my wheels. A 265/40 is just over 1.5" taller than stock. Besides not fitting, it may look like an old muscle car with too much rear tire.

My 2 cents, hoping it helps out.

Well here's the thing with mine. I'll try and get a picture of it. Because of the particular style and offset (35mm), the outer edge of the wheel sits pretty close to flush with the outer fender. It had me confused for a very long time as I was looking to the inside with the car jacked up trying to figure out where the f*** it was rubbing since I thought it was on the inside.

So that being said, if the offset was higher and therefore the wheel sat further in, which it could because there is plenty of room, the 265 would fit no problem. I could probably even fit a 275 if the offset was just right.

I guess what I'm trying to say is there are a lot of variables to make it a straightforward yes/no answer to whether or not it will fit. I do plan on eventually getting coilovers and will get new wheels that hopefully sit in a little further in to avoid rubbing issues. May just get a custom widebody job done.

Thanks mate. I've spent a bit of time on those calculators. Works out about 5mm wider on each side and 8mm larger diameter ... Therefore 4mm closer to the top and sides of the wheel arch. I would have thought that's pretty minimal really. I know it will fit and turn. Still not sure whether it will rub with ppl in the back or a trunk full of stuff.

Good Year Eagle asymmetric 2,, very very good tires!

Got them on my C55, had a LOT of traction issues with cheaper tires, worn out almost instant.
Been running these Good Year´s now, And all i can say:they´re lasting more than twice as long as my Falken´s did...

Cheaper in the long run....

Hey mate ... how do you find them for noise and comfort? I'm debating between:

PSS / PS3 (PSS are hard to get in my size in AU and Michelin have stopped companies from shipping from US to AU ... b@st@rds) - hear michelins tend to be a little wider than most other brands at the same size
GY Asym2 - Hear they have a very nice rim protector
BS S04 - I hear these are bulkier than the rest, might be hard to fit 235s in the front
Conti Extremecontact DW / SC5 - Had SC3 - seem pretty skinny and rounded at the edges

I had a feel around the inside of the tyre up near the strutt at full lock with the 225/40/18 htrz3s ... clear by just over 10mm ... gonna be very tight with a 235, especially with a square sidewall. Any ideas which of those 4 are likely to be narrower? I'm beggining to think I might be best sticking to 225f and 255r.

swedepat

yes the rimprotector is 'enlarged' compared to others, actually really ugly on wrong sized rims.
comfortwise the tires are quite good, low noise, stability, ís good.
Little litte bit 'loose' on small steeringangles, but finds grip direct anyway.
This actually makes them really comfortable on the highway.

I can´t compare them to pilotsport at all actualla as i never had those on my car.
But thy beat falken, Toyo, Dunlop with ease.

Be sure to get brand new ones, the asy2 got updated a couple of months ago here in sweden, new build inside to get more traction on wider tires.

Rgds.
