1969 Ford Mustang Shelby Cobra on American Racing 18×8 & 18×9.5 Wheels with 245/45R18 & 285/40R18 Tires

This 1969 Ford Mustang Shelby Cobra gets a clean restomod upgrade with a classic-inspired wheel and tire setup that stays true to its heritage while improving stance and performance.

It’s running American Racing Shelby Cobra wheels, sized 18×8 up front and 18×9.5 in the rear. The staggered setup gives the car a proper muscle stance, with a wider rear to match the aggressive look these cars are known for. The Shelby Cobra design keeps everything period-correct while still benefiting from modern sizing.

Wrapped in Nitto tires, the setup features 245/45R18 up front and 285/40R18 in the rear. The wider rear tire adds traction and gives the car a more planted, performance-oriented feel, while the front maintains responsive steering and balance.

Factory vs New Specs

Most 1969 Ford Mustang models originally came with bias-ply tires roughly equivalent to 205/75R14 on 14×6 or 15×7 wheels with high positive offset.

• The move to 245/45R18 front and 285/40R18 rear keeps overall height close while significantly increasing tire width
• Front wheel width increases from around 6–7 inches to 8 inches, while the rear steps up to 9.5 inches, creating a proper staggered stance
• Wheel diameter increases to 18 inches, giving the car a more modern look while maintaining classic proportions
• The wider rear setup sits noticeably farther outward, giving the Mustang a more aggressive and planted appearance

This setup brings a perfect balance of classic styling and modern performance, enhancing the look and drivability of the Shelby Cobra without losing its original character.
