Need new tires for my aftermarket wheels. 335 or 345/25/20 rear and 295/25/20 front. I know michelin super sports are made in these sizes, but the fronts are non-runflat and the rears are runflat. I've heard bad things about mixing the two together. Need decent traction on the road with 640 rwhp. Have nittos invos now, and not enough grip. I also know the Toyo T1r's come in these sizes, any decent feedback on those? Other ideas? Help!

It's not a bad idea when changing wheels/diameter to make sure good tires are made in the size/diameter you want to run - before purchase. As you get up into the 18-19-20 inch rims tire availability gets very limited.

I would not mix ZP and non-ZP tires. If you are just going to cruise, maybe, but that is probably not why you did the built engine.
