I did some searching around and can't find a clear answer. I have a BMW 2008 328i Convertible (E93). The stock tires are 225/45/R17. I replaced them with 215/50/R17 for winter tires (Toyo Observe Garit KX). What I'm trying to figure out is the recommended tire pressure for these wheels on my car. The manual shows a variety of different sizes and recommendations, but nothing with 215 (most are 225 or 205).
The tires say 50psi max on them and I currently have them at 45psi all round. The reason I went so high is cause they looked low otherwise.
Any suggestions? Your help is appreciated.
