I took an RC car (Traxxas Rustler 4x4) designed for 11.1V(3s) and strapped a 22.2V(6s) system to it, upgraded all transmission parts and it holds up well.
However you can't go full throttle without full ground contact (and barely even then) without shredding the tires into atoms. I've tried reinforcing with glass fibers and various glue compounds but it always finds a weak spot and propagates.
I think the car does around 160kmh, I've GPSed it to 140 but since it's an off-road vehicle it just takes off at those speeds. I assume free-rolling the tires reach over 200kmh, with some napkin math the tires rotate at over 9000RPM (150 per second).
Napkin AI math says the tire could experience as much as 4000G.
It's honestly "easy" to build an "unlimited horsepower" car with EV technology, high-quality cells, high-voltage, expensive components takes you there, tires though...
Also For anyone who wants to watch a lap of nurburgring, it's absolutely insane...https://www.youtube.com/watch?v=td_c1zeEn2Q

I'm guessing the weight of the drivers balls is limiting factor here. Any lighter and the car would not be able to go so fast.
Granted, what that essentially means is that the engineers went "balls too big, let's cap this in case the tires explode or the car flies off the track."
Seriously though, the driver is putting it all on the line here. Driving a brand new car balls-to-the-wall at 300mph around a curvy race trace ... it's basically like being a test pilot with no parachute or margin for error.
> 308mph
This car has more kinetic energy than a fully loaded semi truck traveling at 70mph.
