CERTAIN SPORT UTILITY VEHICLES AND TRUCKS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 110, "TIRE SELECTION AND RIMS." THESE VEHICLES HAVE AN INCOMPLETE TIRE RIM DESIGNATION ON THE CERTIFICATION/TIRE LABEL LOCATED ON THE DRIVER'S DOOR EDGE. IN ADDITION, THE LABEL MAY ALSO BE MISSING THE TIRE LOAD RATING ON THE LABEL. ALTHOUGH THIS INFORMATION IS NOT REQUIRED BY THE STANDARD, IF A TIRE OF A LESSER LOAD RATING IS INSTALLED, THE TIRE MAY NOT BE ABLE TO SUSTAIN THE LOADS ENCOUNTERED DURING USE.
Consequence & remedy
Consequence: IF A CUSTOMER REPLACES A WHEEL AND ONLY RELIES ON THE RIM SIZE DESIGNATION THAT IS INDICATED ON THE LABEL, A WHEEL THAT IS OF A DIFFERENT RIM CONTOUR DESIGNATION MAY BE INSTALLED. IT MAY BE DIFFICULT OR IMPOSSIBLE TO MOUNT THE TIRE ON A WHEEL WITH THE WRONG CONTOUR. IF THE TIRE IS MOUNTED ON THE WHEEL WITH THE WRONG CONTOUR, THE WHEEL AND TIRE MAY NOT PERFORM AS INTENDED, WHICH COULD INCREASE THE RISK OF A CRASH.
Remedy: A LABEL THAT WILL CORRECT THE LABEL ORIGINALLY INSTALLED WILL BE MAILED TO CONSUMERS ALONG WITH INSTALLATION INSTRUCTIONS. THE CUSTOMER WILL HAVE THE OPTION FOR DEALERS TO INSTALL THE LABEL.
