Hi! I desperately need new tires and want wider tires this time, so I thought I would up size my wheels at the same time. I have researched so much information as to what will fit my car without causing problems like rubbing, increased gas mileage, having to change calipers, rotors, etc. but I am reading conflicting information. Here are 3 ideas I was contemplating but I need advice as to the pros and cons and whether they would be compatible with my 2006 V6 Deluxe version Convertible. Any help would be greatly appreciated! 1.) 2013 GT OEM 18x8's with 235/50-VR18 Pirelli's w/1500 miles used on tread (Craigslist ad) 2.) 17x8 Bullitt Rims (non OEM) with Sumitomo All Season A/S P01 Tire - 235/55-17 (American Muscle) 3.) Stay with current stock 16x7's and get 225/60-16's from local tire shop.
