What is the widest tire I can put on OEM C55 wheels? Visually it looks like a another 10 mm both front and rear (235/255) would be okay. If so, what's the best tire to move to?

Im going to second this question.

Being new to car tires: wouldn't a wider tire give better off-the-line grip? Can we even go any wider with the stock rim/setup?

235's fit up front and 255's fit in the rear. you could even go 265 and possibly 275 in the rear if you wanted

Remember wider tires weigh more and in the worst place to add weight

SoCalC55

mmm so its better off just getting a new set of 245/35ZR18s, just in a tire that dosent suck like the Continentals?

Or does a slight increase in size make up for the slight increase in weight

The Conti's suck for sure, Had them and hated them. I ran 255 on my stock wheel and I didnt notice any power loss. I bet a dyno would have shown a bit of power loss though.

I wouldnt go bigger than 255's in the rear on the stock wheel, but thats just me.

Just because a tire is wider, doesn't mean it is also heavier.

I would suggest 265/30-18s or even better 275/30-18s (rear), they should fit nicely.

Depending on the tire an extra 10mm on all tires would add no more than 10lbs.

The car currently has Pirelli PZero. These come in a 255/35/18 and 245/40/18 and would add about 8lb of extra weight.

I'm running 255's on the rear of my C55 with absolutely no problems

RedG

Width, profile, and construction all factor into weight, but just because it is wider, doesn't mean it is heavier.

its a 9.5 rim isnt it? 255 is the norm

I run a 235/35/19 front 265/30/19 rear for the c55. tried running 275 on my coupe, it rubbed a bit.

I though anything bigger than 255 in the rear requires fender roll...
I would go with 265 next time then

AMG Sleeper

i'm a big fan of my Toyo T1R Proxes... great tire, great grip, pretty good wear as well... and good value buy

my setup is 235/255 as well

I thought the stock rim was 8.5 inches.

255.

According to MB it is:

Interesting. If the front is only 7.5 inches then will a 235 even fit well? I thought 8 inches was the smallest a 235 would go on without have any issues.

Edit: Well, AMGSleeper says he's running a 235, so I guess its workable.

im running goodyear eagle f1s in 265 in the rear and they rub when i have people in the back seat. a good fender roll and grinding down part of the bumper tabs cured it

AMG Sleeper

i checked mine last night, i have 235/265 setup

AMG Sleeper

workable... AND effective

Does ur tires sticks out at all? Do share some pics of ur car with 265s.. I should be replaceing my Kdws soon and I'm thinkin about putting bigger ones this times

Thanks in adv!

Are those 265s on the C55 in the photo?

xplosiveg06

yes.

but now that i think of it, 265s are too wide for a 8.5in wide wheel thus why i am now looking to get aftermarket 9.5in wide wheels in the rear now. i'll take a pic of what 265s look like on a stock 8.5 tomorrow. 255s i think is the way to go with stock wheels.

SoCalC55

Im going to have to come over and take a look at the tires Marc, although im going to end up going with the 255s.

How are the F1D3s(id assume thats what they are)?

xplosiveg06

the tires are much better than the stock continentals i had on the car before. i am loving them in the rain


here are some crappy pics i took to try and show how they extend over the lip of the wheel. i think they have a rim guard, but they protrude more than there supposed to due to being too wide for the wheel
