Hey I have a 2013 GT convertible, factory suspension. I'm looking at Niche Verona M149 rims in 20X9 and 20X10 or 10.5, which would you recommend? Everything says run a 255/35/20 up front and 285/30/20 out back but thats a smaller overall diameter. I'm wondering if I can fit the 10.5 inch rim (30mm offset) out back with a 315/35/20 and a 245/45/20 in front? Or would you go 245/45/20 and 275/40/20 on the 10 inch rim (40mm offset)?? NEED HELP! I don't want it to stick out past the fender and possibly hit over a bump. What do you guys think? Pics of your cars with something similar would help too. THANKS!
