I didn't ask if the 14" Goodyear Eagle ST tires and 14" Goodyear rear slicks are going to be included (in addition to the larger diameter Foose wheels and matching tires and the stock 15" Rally wheels and skinny tires) but even if they aren't, the STs are still easily to found on eBay or from other sources.
The optional 14" Cragar 5-spokes the original 3'n'1 kit included are pretty outdated by now, and the 14" Centerline two-piece-look wheels included with the '67 Vette kit also scream 1980's, so I can understand Revell adding a new set of wheels and tires to freshen up this kit. The wide whitewalls from the '57 Chevy Bel Air kit are one of the only other commonly available kit tires in 1/12 scale, and they look out of place on a late '60 ponycar, so tire options sourced from kits are quite limited. The Camaro's 15" Rally wheels are very basic, too, with the wheel, trim ring, and center cap all molded as one piece. You could source the Goodyear Gatorback 16" tires from either the 1/12 Testarossa or F40 kits, but again you're limited to the 5-star Ferrari wheels unless you want to make or modify your own.
I hope this kit leads to the 1/12 '67 Vette being reissued with similar, larger diameter wheels and tires, too.
