well, i tried to drill a small 1/8 hole in the rims. 3 went good, 1 wasnt so great. anyways, this one deflates much faster when pushed with a hand, and when deflated, it feels solid, by that, i mean it feels as if there is no foam. should i buy foam or a new tire? anddo masher 2000's fit on 2.8 inch all star rims? thanks
