ON MARCH 29TH AT 2:20 PM I HAD BOLTED ON AND TORQUED TO SPEC BRAND NEW TIRES AND WHEELS(WHICH I HAD BOUGHT FROM CUSTOM OFFSETS ONLINE AND WHERE SHIPPED TO ME BALANCED, MOUNTED AND READY TO GO) THEN AT AROUND 3:30PM THE INCIDENT OCCURRED. I WAS TRAVELING DOWN THE FREEWAY ABOUT 70 MILES AN HOUR IN THE FAR LEFT LANE AND IN ABOUT 2 MILES FROM GETTING ON THE FREEWAY I HEARD A LOUD BANG AND FELT THE FRONT LEFT SIDE OF THE TRUCK FALL ONTO THE RIM. AS SOON AS THE PRIOR EVENTS TOOK PLACE I SLOWLY STARTING TAPPING THE BREAKS TO WORK UP TO BREAKING FASTER AND HARDER TO SLOW DOWN BUT ON THE PARTICULAR PART OF THE HIGHWAY I WAS ON THE SHOULDER WAS LOSING MORE AND MORE AREA SO I EVENTUALLY ENDED UP HITTING THE K RAIL NOT INTENTIONALLY, COMING TO A STOP. PLEASE ALSO NOTE THAT I HAD NOT HIT NOR RUN ANYTHING OVER ON THIS CLEAN SMOOTH STRETCH OF HIGHWAY. AS DESCRIBED PRIOR I HAD STARTED TAPPING ON THE BREAKS SO I DIDN'T LOCK THEM UP THEN EVENTUALLY FULLY BREAKING AFTER TAPPING. FURTHER TO ADD 4 DAYS LATER ON APRIL 2 I WAS TAKING OFF THE WHEELS AND TIRES TO SEND THEM BACK TO THE COMPANY I PURCHASED THEM FROM (CUSTOM OFFSETS) I NOTICED THE REAR PASSENGER SIDE TIRE STARTED TO COME OFF THE BEAD AND CREATE A EGG ON THE SIDE WALL WHICH SHOWS THAT THERE ARE TWO AND JUST ONE DEFECTIVE TIRES SENT TO ME.THE TIRES WERE TOYO OPEN COUNTRY AT 3'S 315/75/16 AND THE WHEELS WERE AMERICAN RACING WHEELS 16X10'S SUPPLIED TO ME BY CUSTOM OFFSETS WEBSITE BALANCED AND MOUNTED.
