SL/R230: Wheels and Snow Tires for '03 SL500 Sport
It might pay to ask this question in "The Tire Rack's Wheels, Tires, Suspension & Brakes Forum" down below.
I've had this SL for 5 winter seasons now, living in the North Central Pennsylvania Allegheny Mountain area (State College, PA)- and cannout use it in Winter unless it has 4 snow tires. I have an extra set of 4 Wheels - with Pirelli 240 SnowSport 255/40/R18 95 on from mid-Nov thru mid-April each year, and they work fine. Try TireRack for tires like this.
