The proper tire size for a 1998 Pontiac Transport is P205/70R15. This info is on a sticker placed on the driver's door jam.
It varies from tire to tire. It will be imprinted on the side of the tire and also inside the drivers door post.
Tire key? Do you mean a lug nut key? GM Dealer.

for one you need to loosen your lug nuts before you jack up the car,
steel belts are used on radial tires for strength,they sometimes break and you will feel a bulge on the sidewall of the tire,also you may get a shake or shimmy in the front end.Replace as soon as possible
