Can anyone tell me if I can use 265-35-18 on the front
and 305-30-19 on the rear in my 2012 base C6 coupe?
What will it do to the driving experience? Will they bottom out or rub? Will it improve handling?
Thanks

People use those sizes, but I can't comment on how they work.

Thank you. I agree but I would want to know the ups and downs of the upsizing. I appreciate your comment.

I use those sizes. They seem to work great. No rubbing on my brake ducts or fenders. Some say the sidewall acts differently but I dont have that much experience with tire sizes to comment on that , yet if you're auto-xing I'd say go for it the most rubber helps

ps.no scrubs in those sizes so cost plays in. Ill be using sizes that scrubs are available in next time

Thanks for taking the time to answer in detail. It is helpful information.

Have you seen faster autocross times by going from stock size to "oversized" tires for the wheels?

Yes but I went from 6 yr old street tires to R888's so i can't say exactly the benefits. All the reading I do on racing say more rubber for AX is good

I am going with Advan ADO8's in the 265-35-18 and 305-30-19 sizes.
Unless there are reasons not to. So far there have not been any other than cost.
Thanks
