I am a chump change and I don't want to spend crazy loot on new tires at $235 and up a tire. I want 18" rims and my tire choices are 225/40/18 or 235/35/18. The 225/40 are to skinny for my liking, unless you can convince me they don't look to bad. M3/4 has stock suspension, but I will get the H&R sport springs and Bilstein shocks. Thanks in advanced.
