Wheels-Tires What Are The Widest 20" Front Tires

I'm going with Nitto NT01's and 285/35ZR20 is my only real option. I hope it ends up working If I could tweak the offset or backspacing a few mm I should be fine. Just hunting for wheels that fit.
keep in mind the fact that the wheel studs are now 14mm as opposed to prior years being 1/2"... Make sure the wheels you choose will fit over the studs
 
What kind of wheels are those? They look great!
 


I know this is an old thread but since you drive it daily, how is the harshness of the ride different from the stock 18" wheels, and how much did the gas mileage drop when going from 235's to 275"s all around?
