Tire Question: Step down to 255/60r17 or up to 275/60r17?
Hey guys,
I'm having trouble finding decent All Season tires at 275/55r17 for a 2005 ML350 SE with 17x8.5 rims. What would be the downsides to either going with a narrower 255/60r17 or larger 275/60r17 (4.7% speed error)?
Any advice would be appreciated!

The thing with the tyres is to try to keep the overall size (tyre+rim) as close as possible to the original. If you are using 16"rims than your profile must be 65 e.g 255/65 R16. If you have 17" ,then 255/60R17, if 18" then 255/55R18 and so on. Everytime you increase the size of your rim by a inch, you must decrease your profile by 5 units. Look at the examples and you will figure it out.
