I had issue with one set of wheels-tire.
The wheels would not fit the car even if I had specified wich one it was during the order... which was strongly recommended to avoid misfits!
After a lot of arguing, I had to put the tires on wheels around my place and ship them the wheels back (at their costs) and it took them 4 weeks to issue a refund, on the wheels only. They never refunded the installation even if they said they would after I requested it (prior to returning the wheels) because I had to pay for new wheels and to have the tires installed... again.
I have to say that I ordered from them before and never had issue... but I wont do business with them anymore because if anything goes wrong...
