Hello,
I was at Kelsey's when the first shipment of these tires was off loaded. The GR70-15 Goodyear Custom Tread also know as the 'Steel Belted Radial'. This was the first tire that used a tread pattern designed by GM also known as TPC Spec. Please feel free to contact me with any questions you may have. My cell is 816-654-3400.
