Hi guys, I have two questions regarding my new wheels. I thought I make it into one thread to simplify things. First question is this, I just bought a set of BBS RX203 17x8 ET10 wheels for my E30 sedan. Can anyone help me with the tyre setup? I'm thinking 205/45r17 maybe? I'm running H&R springs with std shocks.

My second question is regarding the wheel studs. What is the suitable size for my setup? How much thread should I have to be safe (how long should the stud protrude) before I need a set of new studs? Thanks
