I can't protrude 24.6 inch diameter on my car since I have the sports package suspension and body kit I'm looking to go down a size or two on my rim and have the biggest sidewall that I can have is anybody have any calculations for me what my bolt pattern is what size tire I should use to be much appreciative because I had the car for 2 months already have a bubble on the side of my freaking rim I know it's not made for PA roads around here we have potholes that swallow cars let alone rubberband freaking tires
