what size 18" tires will fit an '04 S55?
for my 2004 S55 the stock sizes are listed as
245/45R18 front
265/40R18 rear
I'd like to know if these will fit
255/40R18 front
285/35R18 rear
I suspect the 285 may not fit on stock AMG rims, and if so I might as well upsize to 19" if I'd have to buy new rims. In that case, I'll need to start a search for 19" tires. I'm not too keen on the painted finish anyway.
My goal is to find asymmetric all-season tires that can be flipped side-to-side to help them stay quiet. This is a big pain in the *** because the S55 tires' load rating is very high which greatly limits the selection.
I can calculate circumference just fine, it's width and clearance that are my concern. You might notice that the two specific sizes I asked about are both *wider* that the stock sizes.
I have 275" ON my S55 ... if stcck height is ok.. when lower it will rub...
hope that help..
i haven't lowered it, and probably will not. I would like to lower it just a bit (less than an inch) to help fill the wheel wells, but I am already worried about keeping the nose off curbs when parking, so I will probably not lower it. If anything I would go up to 19s, but the stock look is more than satisfactory if the alternative is a new set of AMG wheels just for cosmetics.
thanks again for the useful response.
Many people, including Luke at Tire Rack, have suggested going with 275/35R18 in the rears for "improved performance," and in going from high performance summer tires to all-season tires I can see where extra width would help make up for lost tread grip.
Also, I may have misunderstood your "monster truck" comment. Did you mean there would be even more empty space in the wheel well with the 285/35? I was thinking you meant the sidewall would be taller.
