I was looking for a thread for the Mercedes Benz 300 SD, w126 chassis. I have two question, first on the correct tire pressures located inside the gas flap according to what I have read this is the correct pressure to use. Michelin Tires verified this as I am running Energy MXV4. Second thereare two readings one for summer tires and one for winter tires. If you are running all seasons do you just go with the summer pressures. Comments welcome.
