Need help on tire size suggestions

Thinking about getting Hoosier slick for Autocross. 315/40/18 rear on stock rims. What size for the front? Will I have a problem? Thank you.

The 245/40's look like your only option, they should fit. The A7's are the autocross/hillclimb version.

Thanks for the response. Im getting a good deal for a R7 315/40/18. Will it fit my stock rims with no issues. Thanks in advance.

A7 would be better. R7 has to be warmed up. 315/30/18 would be a better fit, not sure if the 40 series would be too tall. https://www.tirerack.com/tires/tires...r&tireModel=R7
