There are lots in 315/35/20, but those are 1.5" taller than the OE 1LE tires and that's a bad idea for a lot of reasons. You'll hurt performance in lateral grip, braking, and acceleration with those tires. You'd be far better off to stay with the stock 305/30/20.
I definitely won't be going with 35s! If I can fit 315/30/20 without issues I might give that a try, assuming I can find some.
