Authorities say a York truck dealership has been struck again by a thief or thieves who stole expensive tires off tractor-trailers.

York Police Chief Don Klug told York media that it was the second theft from Sahling Kenworth in less than two months. The most recent theft, of 12 tires from four semitrailers, was reported on Saturday morning.

Klug says the crime would have taken a considerable amount of time and likely involved more than one person who had the right tools for the job. He says each tire costs around $500.

The chief says he suspects the same people pulled off both heists. No arrests have been reported.
