This is a set of used Dunlop GP-A tires. They are med/hard compound (DT.13 rear) and (8148/7455 front) dot race tire. This is a multi compound tire meaning one side is med compound and the other side is a hard compound. This set only has 14 laps on them and still has a lot of life left in them. Please contact me with any question.  I do have more sets I will be selling if interested we could work out a bulk buy price. Happy Bidding!!!
