SLK/R170: Getting new rims; what bolt pattern fits?
Bolt size: 12mm
Rim offsets should be: 35-37mm for front and 30-37mm for rear.
Rim width should be 7-8.5" for front and 7-9.5" for rear
Tire width should be 205-225mm for front and 205-255mm for rear.
Tire diameter should be within 3% of stock and the front tires diameter should be within 3% of the rear tire diameter.
You risk rubbing problems if you go outside the ranges for offset and tire width.
You risk ABS/ASR/ESP malfunctions if you vary the tire diameter too much.
