Hi buddy,
The price I paid was an offer and as I was told by the salesman, he had 3 sets of the specific alloy type (No159) and sold out in 2 days!! (I bought the last one!!)
I was worried about the tyres DOT too, when I went to pick them up I checked them and I saw that they had DOT 38/08, very good one!!
DOT 38/08 is great.
As I wrote, this was a great deal for you. I would have bought them, too.
The salesman seems to be not the best business man. He could have sell these 3 sets at quite better prices, no wonder, that he sold the three sets within 2 days. But good for you.
