Cornering force and wheel / bolt strength.

What lateral force does a wheel endure at the bolts / holes, in a hard corner at the limit of lateral adhesion ?
Obviously the wider the wheel, the more rubber and the more grip and the more lateral force exerted on the centre of the wheel at the bolt holes. This maximum force may be compounded at the bolt holes through "lever action" over the radius of the wheel too and will vary depending on the surface of the roadway. I imagine the force will disipate some once the tyre starts sliding and be at its highest the moments before sliding.

Lets use for example a 255 x 35 tyre, on a 18" wheel mounted on the rear of a 328 in "90 degree" oversteer, or 225 x 45 x 18" in "90 degree" understeer in the fronts.
Assume a dry roadway with very very good grip.


To what extent does this force challenge the wheel bolts or studs or even the magnesium of the wheel especially at the bolt holes ie trying to tear the bolts through the wheel or snap the heads off the bolts ?

What is the minimum thickness of magnesium between the bolt head and the hub and the minimum thickness of bolt that would be required to keep the wheel bolts from snapping off or tearing through the rim and folding under the car ?

I have steel inserts ( splined to the outside) pressed into my wheel bolt holes. The shop says they are pressed in with 4 tonnes of force. Are they to be trusted with the expected maximum lateral forces acting on the wheels ?

Has anyone ever seen bolts snap off, or tear through the wheel in a hard corner ?
On a standardly shod 328 which would be the weakest point ? Bolt shanks, bolt threads or the magnesium bolt holes ?

Its going to take a bit of engineering experience, science and maths, but i know someone out there is up to these calculations
