Pontiac's G8 was only around in 2008-09 and was actually an import from the company's Australian Holden division. The G8 was a rear-wheel drive sedan that filled the niche left by the discontinued Bonneville and Grand Prix, and was available with a high-output V6 (361 horsepower) or V8 (402 horsepower) engine with the V8, and featured GT and GXP trim levels.

For a great set of all-season tires for your G8, get a look at the Bridgestone Potenza RE050A, Continental ProContact TX, Michelin Pilot Sport A/S 3+, or Goodyear Eagle RS-A. If you're thinking ultra-high-performance tires, check out the Dunlop Signature HP, Yokohama Advan Apex V601, Pirelli Cinturato P7, or BFGoodrich g-Force COMP-2 A/S.
