When @Napa Paul and I bought ours earlier this year we dealt with this guy:
Michael Gromadski (?) cell: (561) 260-7020 michael@305tires.com 305TIRES.com European High Performance Tires
1960 NE 153rd St.
No. Miami Beach, FL 3316
As noted above he was ordering 4 sets in 185/65R15 and by the time they had shipped to him all were sold. Paul did all the leg work and this was the only guy that was really responsive. All in cost drop shipped to Greg in California was $345 for the set of 4.
