Mustang Mach 1 Handling Package Features Shelby GT500-Sized Tires

Sponsored Links

So far, Ford has told us virtually everything there is to know about the forthcoming 2021 Ford Mustang Mach 1. However, it had yet to reveal what size tires would be present on the reborn model. We took a guess at those numbers way back in June, before the Mach 1 was even revealed, and as it turns out, we were 100 percent correct. Even better, the Mustang Mach 1 Handling Package comes with the same size tires as the mighty 2020 Ford Mustang Shelby GT500.

S550 Mustang Tire Sizes
S550 Mustang Model Front Tire Size Rear Tire Size
GT 235/50 235/50
GT Performance Pack 1 255/40 275/40
GT Performance Pack 2 305/30 305/30
Bullitt 255/40 275/40
Shelby GT350 295/35 305/35
Shelby GT350R 305/30 315/30
Shelby GT500 305/30 315/30
Mach 1 Standard 255/40 275/40
Mach 1 Handling Pack 305/30 315/30

Ford Authority has confirmed with Ford that the standard Mach 1’s Michelin Pilot Sport 4S tires measure in at 255/40R19 front and 275/40R19 in the rear. As we previously reported, those tires will be wrapped around Tarnished Dark-painted Low Gloss Aluminum Wheels measuring in at 19-inches x 9.5-inches up front and 19-inches x 10-inches in the rear.

However, Mustang Mach 1 Handling Package cars come equipped with unique, wider 19-inch x 10.5-inch front, and 19-inch x 11-inch rear Tarnished Dark-painted aluminum wheels wrapped with 305/30R19 front and 315/30R19 rear Michelin Pilot Sport Cup 2 tires. These are the same size and type of tires present on the Shelby GT350R and GT500 (though the GT500 uses 20-inch wheels) which are the largest fitted to any current Ford Mustang model.

These massive tires should play a big role in the Mach 1’s on-track performance, which Ford says is on-par with the GT350. Of course, there are many other components that contribute to that capability, including a larger, unique, higher downforce front splitter, new front wheel lip moldings, a low-gloss Magnetic swing spoiler with a Gurney flap, all of which gives the Mustang Mach 1 Handling Package 150 percent more downforce than the Mustang GT Performance Pack 1. And for those that don’t like to row their own gears, Ford’s 10-speed automatic is now available with the Handling Package, too.

  1. The staggered wheel/tire sizes on the GT PP1, the GT 500 and the Mach 1 handling package are an interesting arrangement. I’m assuming that the rest of their suspensions are tuned for this arrangement? Most track oriented setups seem to prefer a “square” setup like the GT PP2. Everything I’ve read and heard leans toward it being easier and more consistent to “dial-in” front/rear suspension balance with a square arrangement.

    • Interesting observation Mark. From what I understand, a properly balanced car shouldn’t need a square setup. The PP2 had it because Ford optimized to make up for sub-par suspension performance. I’ve driven my GT350 with the staggered setup extensively at 2 tracks and it does much better than my brother’s PPL2 on the same course, despite him having wider fronts.

  2. I am trying to do a pre order for a mach 1. I want the handling package. My deal is telling me that it is not listed on the form. Has anyone else had this issue? What package number is the handling package?
