2015 C300 question for suspension and tire
So, I was wondering is anyone know how to make suspension makes more softer? Or I'm thinking to change run-flat tire to more comfortable tire. I'm guessing basic tire which is PROCONTACT GX SSR too hard for comfort ride. Can someone recommend replaceble tire? Tire sizes are front 225/45R18 and rear 245/40R18. I'm planning to raise aspect ratio about to 225/50R18 245/45R18 if it's possible.
Any info from other owners would be appreciated.

Have you checked your tire pressure yet? The recommended pressure is listed on the drivers door sill.
What will you do for a spare if you ditch the run-flat tires?

I guess I'm used to that information being on the door sill on my past vehicles, and not on the gas filler door.
What do you use as a spare if you got rid of your RFTs?
