FEATURE Most Police Tires Are Fixed Wrong ARTICLE SUMMARY
Half the time, repairs to the speed rated tires used on police cars are done wrong. That is probable cause to never put a repaired tire back on a pursuit-rated sedan. The correct repair is a plug-patch. The plug part keeps moisture out of the inner belts. The patch part holds air. Both are required.

For H-rated and above speed rated tires, Goodyear allows only one properly performed repair (and to the belt area only) for the original speed rating to be maintained.
Fix them right or adopt a “no repair” policy. BY POLICE FLEET MANAGER STAFF
Of these, 52 percent fi xed the speed-rated fl at tire in such a way that either the speed rating was lost, which means a maximum certifi ed speed of 85 mph , or the speed rating defaulted to a Q-rating (99 mph). T e Rubber Manufacturer’s Association sets the standards for the

tire industry. T e RMA leaves the tire repair policy and the resulting speed rating up to the individual tire manufacturer. Goodyear has published a very specifi c procedure to repair a speed rated tire. If the

procedure is properly followed, Goodyear is clear: T e tire will retain its original speed rating. T e H-rated tires remain H-rated, and the V-rated tires remain V-rated. However, Goodyear allows only one properly performed puncture repair for the speed rating of the tire to be maintained.
For their part, Firestone recommends exactly the same repair proce- dure. However, with an uncertain risk of internal damage caused when the tire went fl at, even when the procedure is followed, these repaired tires would no longer maintain their speed rating. After a repair, the maximum speed would be 85 mph, no matter what the original speed rating was.
