This car was built with the bigger is better concept. Staggered or non-staggered, I believe in fitting the largest tires you can where you can. If that means 255 on the front and 345 on the back, then try to tune it out with suspension. Use a lot of rear roll stiffness !
Now a pure racer would disagree, might find advantages to lighter wheels and tires. But on our big motor, heavy, pro-touring inspired rides, I just don't see a point in hamstringing the only thing that keeps the car on the ground. I think the wear patterns are different for the front and rear too, so sure you can rotate them, but I find I keep the rear tires on the car a lot longer than the front if I am tracking. Now if you are basing it on economics and/or crash replacement that is something different.
Another idea I have is the car is mostly tuned for the track and the 335 front tires. On the street I mostly leave the suspension alone (because its a lot of work changing stuff around anyay) and my street tires are 285 up front. So that gives me some built in understeer (safety). Not that I ever really push cornering on the street anyway. The downside is that the 285 doesn't fill up the fenders hella flush
I realize we are discussing performance, but c'mon these cars need big tires anyway ! And for performance, a front biased front engined car needs more front tire if you can fit it.
