Ok. I have searched around the forum for a thread that talked about this but, I found nothing I was looking for. So...Im looking to upgrade from the stock 16s to an 18. Now, first question, how wide can i go? I will be installing eibach springs here soon. Question 2, I have seen this website 10101 something or other, anyway, what size tire would be best to run? If I remember correctly, from what I last saw, 225/45/18 would be a good fit. But that was not compensating for the lowering. Any knowledge would be greatly appreciated.
