I purchased a used 2007 R56 Mini Cooper S. It is currently running Bridgestone Turanza 195/55/16 RSC tires that are due of a replacement. I've read a lot on this forum about getting away from the run-flats for a smoother, quieter, cheaper ride. I'm all about smoother, quieter, cheaper. I'm mostly interested in a quieter drive. I've read good things about moving from the 195/55/16 RSC's to 205/50/16 Yoko Envigors (non-run-flats). QUESTION #1: What brand of tire and tire size would you recommend if moving away from run-flats? I like quiet and I live in Houston so I don't think I need all season tires. We have two seasons here. HOT and HOTTER. QUESTION #2: I need to be prepared for a flat. Based on what I've read, I don't want to carry a donut spare and I don't want to use slime. I was thinking of carrying just plugs and three CO2 cartridges. I might add an ultra-light air compressor if I find a good one. Anyone going the CO2 cartridge route? If you are any recommendations and things I need to keep in mind?
