Don't buy them till you know what the outside diameters are, I can tell you 18 19 combo but not 19 20. There is a % of course and a calculator. There are some experts in here that will give you the percentage but hold off till you get it...

Multiply the front tire diameter by 1.04 to get the desired rear tire diameter. You have to stay as close as possible to that spec. I don't remember, percentage wise, how far you can stray from that spec.

Hi. I have 19x9 and 20x11 as well. I run 255/35/19 and 305/30/20 and all of my systems are perfectly happy. it's very close to stock O/D, so it keeps everything in check.

Can you send me a pick of how it looks? I'm so glad to hear this! I was afraid i would have to go 285/30/20 on the rear. I really liked how the 305/30/20 looked! Also my car is lowered a inc. I was wondering if yours was also. I'm just afraid i might have some rubbing issues.

mine is slammed with aggressive offset wheels to clear z06 brakes, on a base c6. no rubbing..... until I had to add a 3mm spacer to clear the rear brakes. -1* camber, raised the rear a tad and shaved the inner fender lip with sandpaper and it's good now.

you'll like this tire size combo. mine looks a little goofy since I had to raise the rear a bit, but you won't run into this same issue.

just have cell phone photos at the moment.

Thank you for the information and picture bro! I love the white and black combo! My car is pretty low to, but I'm glad to hear someone can still run the tire set up i want. Your set up is exactly what i was going for. All the local tire shops wanted me to run a 245/35/19 and 285/30/20

what a weird tire size for a rear wheel that wide. the rear would have looked a little stretched, I bet you would have been irritated with them! no problem man. post up some photos when you get them mounted :]
