Hey i have 275/35/18's in the front and i need new rear tires, can i put 315/30/18 on? is it ok to have a different middle number 35 in the front and 30 in the back? also, where the hell can i find these wide-*** tires?!

You wont find 315/30/18. Youll only be able to find 315/35/18.

 

Found you some 315/30/18's Kinda pricey.

Also the treadwear on all of those is horrible.

 

tirerack only has drag slicks in 315/35/18
