Suggestion on tire size for 20x9.5/20x11

Hey guys I've got Forgestar F14s in 20x9.5 and 20x11 (a 20x10 wasn't available back when i ordered them) and have been running the traditional 275/315 combo for the last 2-3 sets. Any experience with other sizes? I thought about doing a 1LE/ZL1 setup but I believe a 275/40 is the biggest i can run up front...am I correct there? As for the rears, I'd like to go a little leaner...maybe a 305 or 295. This is for my daily, city driven SS on coilovers with no plans of any auto-X or drag racing. If someone could help point me in the right direction I'd appreciate it. TIA!

285/35/20 is what I have on the front of my car. And I'm running the same size setup you are.

Michelin Pilot SuperSports in that size are approved for a 9.5-11" wheel according to Michelin, but other tires may differ.

So you got a 285/35 on a 20x9.5 up front? That'd be great. Thinking I could pair that with a 295/35 on a 20x11 in the rear

That's what I currently have and I'm not super thrilled with it. A 315 looks good, but aside from that it's just extra rotational weight and handles like crap.

That's exactly what I have. Michelin Pilot SuperSports. Handles great.

Alignment specs (dropped 1") is -1.4 camber in the front, -.6 camber in the rear. 0.10 total toe in on front, and 0.20 on back.
