2018 Base wheel upgrade question

ITGUY

I will look for a better deal, but the Michelin Pilot Sports are darn close to $500.00 a corner.

So with 19 x 10.5" rear and 19 x 9.5" fronts, what non-square tire size \ setup would be close to max for the car?

Maybe 285 front and 305 rear?, or is that a bit much? 305 might be a little TOO massive on the rear?

Like i said, no plans to drop the car til warranty is over. I know if the engine puts a rod through the side of the block, warranty should NOT be affected by unrelated mods like lowering springs or coil-overs...but I dont feel like tempting fate.

I am keeping the 4 factory 18" wheel \ tire setup in storage and I also have already purchased 4 x 18" RAY replica wheels and snow tires for the Winter.

I know, I know....Winter.....but i can only store one car for the Winter and thats my other car so the Z is going to get driven.

Thanks for the input
