1965 Mustang Stock Tire Size: A Comprehensive Guide
The Mustang, Ford's iconic muscle car, is renowned for its power and aggression. But have you ever wondered about the stock tire size of the 1965-70 Ford Mustang? Vehicle owners and enthusiasts often look to upgrade components for improved performance, but it's essential to understand the original specifications. Here, we delve into the stock tire size of the 1965-70 Ford Mustang and explore its evolution over the years.

The first-generation Ford Mustang, produced from 1965 to 1970, came with two standard tire sizes depending on the trim level. The base models were equipped with 6.50-13 whitewall tires, while the GT and Shelby models sported wider, more robust 7.35-14 tires.

1965-1968 Ford Mustang Tire Sizes
The initial models, from 1965 to 1968, maintained consistent tire sizes across their range. The base models were fitted with 6.50-13 tires, which were 6.5 inches wide and had a 13-inch rim diameter. These tires were perfect for everyday driving and provided a comfortable ride.

The GT and Shelby models, on the other hand, came with wider 7.35-14 tires. With a 7.35-inch width, these tires offered better grip and handling, reflecting the sportier nature of these models.
Tire Upgrades in the Early Years

Despite the stock tires' adequacy, some enthusiasts sought performance upgrades. Many chose to fit 7.75-14 tires, which offered a better balance between grip and ride comfort. This size became somewhat of a staple for these early Mustangs, as it could be had from both Goodyear and Firestone.
Those looking for even more grip turned to 8.20-14 tires. While these provided excellent traction, they were often considered too firm for daily driving, due to their harsher ride.
Wheels and Rims

Initially, the Mustang came with 13x4.5 steel rims for the base models and 14x5.5 steel rims for the GT and Shelby variants. These rims were simple in design, reflecting the Mustang's .
As the Mustang's popularity grew, so did the aftermarket for wheels and rims. Many enthusiasts turned to aluminum alloys, which not only looked better but also were lighter and stronger. Today, many classic Mustangs still sport authentic-era wheels or modern reproductions that match the original sizes.
1969-1970 Ford Mustang Tire Sizes

The Mustang received a facelift for the 1969 model year, with a slightly larger body. As a result, Ford increased the tire sizes for the base models to 7.75-14. This change provided a smoother ride while maintaining the sporty handling of the earlier models.
The GT and Shelby models held onto their wider 7.35-14 tires, although the bigger engines in these cars often necessitated beefier rear tires for proper traction.










Vintage Tire Care
Restoring a classic Mustang with period-correct tires can significantly enhance its authenticity and value. When selecting tires, it's crucial to choose those with appropriate accelerated weathering, which mimic the aging process of older rubber.
Additionally, correct pressure is vital. The original specs called for 26 psi in the front and 28 psi in the rear for 1965-68 models, and 28 psi all around for 1969-70 Mustangs. Inflating to these pressures ensures optimal performance and longevity for your vintage tires.
Whether you're restoring a classic Mustang or upgrading a modern one, understanding the heritage of the 1965-70 Ford Mustang's stock tire sizes can help you make informed decisions about your vehicle's footwear. So, roll on over to your local Mustang meetup or online forum, and share your knowledge with fellow enthusiasts. Your insight might just help someone else get their classic ride back on the road.
