Everybody seems to be putting on 225/45/17
Will 225/50/17 not work with the stock cls rims?
Does it look wider, as the width is 7 inches? Or would I have to change wheels to get the wider effect.

Thanks

I think they will.

If you're going with Michelin Pilot Sport A/Ss, then IMHO, the 225/50ZR17s are the best fit for stock rims because they are spec'd to mount on 7 to 8.5 inch rims (see more info here) . Where as the 235/45ZR17s are spec'd to mount on 7.5 to 9 inch rims. Forget about the 235/50ZR17s cause the have an outer dim. of 26.6 inches. Also, the 225/50ZR17s are 0.6 inches bigger in the outer dim. over the OEMs. However, I only see a slight difference on the speedo - 80 mph on speedo is really 78.2 mph. I've noticed a very slight increase in gas mileage without any perceived performance hit. And there is NO rubbering at all (under hard cornering, bumps, etc...), even with the CT springs installed on my '03 CLS 6sp.

As for other tire brands, not sure about 235/45/17s

235/40/17 is the closest wheel size to factory spec according to the wheel/tire calculator

My calc. shows 235/45/17 the closest ????

Zapata has 225/50's on his stock rims, which I saw Sunday in Philly, and they look very aggresive - especially when compared to the OEM Mich's. I'm still planning on going the 235/45 route since these are overall closer to OEM spec, plus AllMotor sent me some pics of his 235/45's on the stock '03 -S rims and they look great! Nobody who has mounted 235/45's on stock 17's have reported any problems of any kind.

I just ordered a new set of S03 in 225-45-ZR17 at 174.00 each. Awesome tires ! Isn't summer here ?

To go from 50 series to 40 series tires, you really should change the wheels to 18". This is the standard Plus One upgrade without compromising the speedo accuracy

I've been through the stock MXM4's and a set of S0-3's (BTW I loved the tires copletely awsome just don't last as long as I'd like, but they stick to the bitter end, mine look like slicks right now and are still great tires)(245/45R17) at 34,000 miles. Right now I believe the next set of tires I will get will be a 235/45R17 Firestone Firehawk SZ50 EP, does anyone know anything about them?
