For wheels I'd look at something at least rotary forged for strength and weight. Cheap cast wheels simply crack when they fail and fail catastrophically whereas forged will bend instead. I went Forgestar as a catastrophic failure at 130mph wouldnt be my idea of fun and the weight savings is pretty big.
For tires you'll definitely want to go squared. You can easily fit 19X10 +40mm's on all 4 corners which sits you right at a 285/35/19 tire. You can even go wider but they get super expensive.
