soft tires would overheat because they are able to absorb more energy than hard tires thus provide more traction.
The hard tires would absorb more energy. The energy going in would be from the heat flux through the tire. In the soft tire, if it's disintegrating, the heat (energy) in the tire has reach maximum and is physically breaking the tire down. The hard tires would survive because they would be able to take in more heat.
I don't doubt like a truck X1 may need harder tires yet what truck can't handle 8 G's around the corner.
A truck weighs multiple tons and doesn't have fans under it. That's why it can't pull 8g, it doesn't have anything to do with the tire.
F = ma
a is the turning ability, roughly
m = is the mass
F = mu*N where N = weight which is not the mass.
m/N_truck = 1
m/N_X1 = >> 1
So the X1 would perform much better than the truck even the tires were just as hard.
In video games you can have both your cake and eat it too; super hard tires that can absorb energy at the same rate as softer tires. Just go to the options and you can even have these tires have the same grip level without any wear.
Well, in GT5, the tire physics are overly simple. The Soft tires never have to worry about overheating or getting destroyed, so it makes it look like a soft tire is always better. In reality, the hard tire will be faster under certain conditions.
Inertia itself is not a force. It just the fact the energy in one direction will continue that same speed and direction until some force counters it. Everything comes down to energy and how to redirect or convert the energy.
Energy is a scalar without direction. You're talking about momentum, the derivative of which is force. Going back to F = mu*N, it can be seen that the X1 will be able to change its momentum at a greater rate than other cars.
m/N is proportional to a
m/N F1 ~ 4*
m/N X1 ~ 8*
*these are guesses, but we know for sure that it's higher for the X1
The X1 will need to bleed off more momentum, but that's not a problem since it can generate more force (which is momentum/time).
F = mu*N where N = weight which is not the mass. Let's say that mu would be higher for a soft tire
at optimum conditions than for a hard tire at
optimal conditions
m/N_truck = 1
m/N_X1 = >> 1
So the X1 would perform much better than the truck even the tires were just as hard.
Going back to mu
mu_F1 = 1.5
mu_X1 = 1
N_F1 = 4*1.5 = 6
N_X1 = 8*1 = 8
Even with less grippy tires, the X1 could very easily beat the F1.
I don't think you have to be a expert in engineering to have doubts about a car that I can use 100% of traction to slam on brakes (ABS off) and still have 100% tire grip to turn the car in the corners. You can even set the brake bias totally in the back.
Why not doubt the physics engine? GT5 is not perfect in its simulation. The X1 we get in GT5 is made "inaccurate" by GT5's non perfect physics. In reality it might very well be just as dominant as in the game, however we can't expect a 1 to 1 correlation.
