On a lighter car like an Alpine, a wider tire would add significant mechanical grip, but when traction breaks, it'll be super violent. Considering the short wheelbase in an Alpine, I would opt for a more conservative tire package. However, on a heavier car, one does need more tires. The Porsche 911 is a fairly light car and by today's standards, it has way too much tire than it needs. But on an electric car, one would need extremely wide tires, due to the additional weight of the batteries. This would be necessary just for the traction optimization under braking. A wider contact patch gives better mechanical grip for braking without locking up. So when I'm looking at some electric cars, they're the right size tire for the size of the car, but considering they're heavier, the tire might be a tad bit low considering the weight. The BMW i4 weighs 4700 pounds or 2200 KG and it's only got a 225mm wide tire. Slightly low. The Ford Mustang Mach E is a similar weight and also only a 225 tire. Slightly small of a tire for such a heavy car. Tesla Model 3 starts at around 3700 pounds or 1700 kg and has a 235 tire, 500 kg lighter than the BMW i4 or Ford Mustang Mach E and yet a 10mm wider tire! So at least the Tesla isn't "under-tired."
