'97 840: just installed new M-Parallels w/ ContiExCont 245/40-18's but don't know what pressure they should be run at. The book/door jam sizes are nowhere close to these sizes so they're of little use. My gut says something like 35F/35R but that's just a guess on my part.

Anyone know?

And man, do those wheels make a big diff. in the looks of the car!!

I run 32-34 psi in my 18's and they are wearing correctly including the 285/35-18 on the rear.

Thanks Terry.
