tire pressure and offset
 

sorry for the :noob: questions

so just put on the factory BMW wheel set style 209 with dunlop winter tires. 2 questions: what is the winter wheel/smaller wheel tire pressure supposed to be? the winters are 18/255/55, the original are the M i think 223 20" so i cant go by whats on the door.

the other question and a silly one is how would one know if the offset is wrong or fits? fairly certain this works and so far driving around no issues but just curious does the trim package matter ? got the M-Sport 3.5i 2013.

thanks

I think this was a case of :rtfm: so I think I have my answers

One bit of noob advice:

Every post you make has an 'edit' button- so you can go back and correct errors. Sometimes it is only active for a while, different forums have different settings.

And tire pressure is one of those things, IMO, that you START with the mfg recommended and depending on your alignment, how you drive, your roads, the specific tires...you monitor tire wear and adjust up of down.
