shot a used flat tyre from 60yrds. penetrated one side from tyre side wall.
question: if the tyre fully inflated will it possible to achieve the same result?
Depends on impact energy which is in turn a function of velocity and mass of projectile VS the integral strength of the substrate + internal pressure. Relates to cheap Korean bike tyre with low structure carbon black filler reinforcement VS more expensive German tyre with better reinforcing black filler delivering better tensile strength together with polymer type ratio's rendering (maybe) better cut resistance... etc, etc.
Too much polymer science 4 my flat brain this time 'o a Fri nite.
But, ya, generally, the higher the internal pressure, the lesser the inward deflection of the sidewall, reducing the surface area of contact, in turn reducing the force transmitted to the object = less chance of penetration (failure initiation), but closer you get to the ultimate strength yield of the object (sidewall) = immediate critical falure.
Uggh, somebody stop me, too much frontal lobe activity for a Fri nite. Maybe some wine....
The place I work for doesn't make 215/40R17's. So, that implies it won't be our brand you'll replace 'em with = I might just take you up on that offer to come shoot 'em up 4 ya (the new ones tha is!)
Just kidding... But, what scooby is it u've got?
I'm lookin' at geting the Impreza WRX SW next Feb...
