My engine temp is spiking and then dropping right now, and while doing so it sounds like the idle stumbles a bit. The coolant gauge on the IC is normal and not moving as far as I can tell. I just drove home from work, nothing too crazy. Recently I've been hearing some excessive turbo sounds, such as like siren noise at low rpm. Could this be related to a failing turbo?
I've been looking at used aftermarket wheels lately and Ive seen a lot of wheels that look great but raise questions. I have stock suspension and live in a city with pretty awful roads, we even get "pothole season" (spring) so I am concerned about rubbing or scraping over bumps.
My main questions are:
What's the difference between 18x8.5 vs 18x8, besides fitment? I'm currently on 18x7.5 with 225/40/18
On 235/40/18 tires, what offset can I realistically run with my expectation? I see a lot of wheels in my area at 35mm, and that seems too wide
Any advice would be appreciated as Id like to get a full understanding before I buy a set of wheels and get disappointed
