Well almost...My father owns a tire/mechanic shop, I mounted these wheels and tires myself, they are brand new prostars. I am sure I tightened them and a few blocks down the road, i felt a wobbling sensation in the front, I had lost 2 bolts and both front wheels were barely hanging on, all the bolts were loose. So I tightened them right there on the side of the road with a cross wrench, went back to the shop, checked everything out and tightned them again with the air gun...1 day later...few miles down, same thing on one side...this in only happening in the front. I have mounted many many tires and wheels on customer cars and what not for 10 years but I have never seen anything like this. At first I thought i did something wrong, but this is just weird. I have 15x7's in the front with 3.5 BS and 215/65/15's. 15x 8 3.5 BS in the back with 275/60/15's. The bolts are straight from weld, 12x 1.50..I do not have the 3 inch long studs. Any insight???? Has this ever happened to anyone or am I loosing my mind. Any info on the exact pounds of torque to tighten these things...
