FS:205/45/17 Runflat Pirelli 240 snowsport runflat winter tires

Hey i have a brand new set of 205/45/17 Runflat Pirelli 240 snowsport runflat winter tires, Heres the deal, they were only rode on for a month!, one wheel kept leaking, took the tire off and it ended up to be the bead of the tire leaking due to being mounted wrong and beat up the bead area, the tire is perfectly fine kind of holds air....looses about 12 psi per week, Anyways ill sell the set of 4 for the price of three, your choice on using the one that leaks or just buy one new tire. either way this is a great deal on awesome tires.
I would like 300$ for the set or best offer!!

Thanks.
