Vehicle model
Pontiac GTO
The Pontiac GTO, launched in 1964, is widely credited as the first true American muscle car: a big V8 (389 cu in, up to 348 hp in Tri-Power configuration) in a lightened intermediate body, designed by John Z. DeLorean's team. It set off the muscle car wars of the 1960s. The original GTO was produced until 1974. The brand revived the GTO from 2004 to 2006 as a rebadged Holden Monaro imported from Australia: rear-wheel drive, independent rear suspension, a 350 hp LS1 V8 and then a 400 hp LS2 in 2005-2006, with a six-speed manual transmission as standard. Highly coveted by collectors (especially the classic models), the GTO appeals to performance enthusiasts. A powerful rear-wheel-drive car: in Quebec, dedicated winter tires are strongly recommended.

Tires and wheels
Tire and wheel compatibility
Comme marque GM, Pontiac partageait largement les entraxes (bolt patterns) GM courants, souvent 5x115 ou 5x120 selon les plateformes, et des diamètres de jantes allant typiquement de 15 à 18 pouces selon le modèle et l'année. Les berlines et coupés grand public chaussaient généralement des pneus toutes saisons de format moyen, tandis que les modèles performance (GTO, Firebird, Solstice GXP) recevaient des pneus plus larges et à profil bas sur jantes de plus grand diamètre. Au Québec, des pneus d'hiver dédiés sont obligatoires et fortement recommandés pour ces propulsions souvent puissantes, plus sensibles sur chaussée glacée. Vérifier toujours dimension, indice de charge et de vitesse d'origine; rester général en l'absence des chiffres exacts par modèle.
