I put them on my stock factory slots and are fine. It was quite the process to order them. Had to order them from a distributor, have them shipped to an importer,then ship to me.The distributor I got them from would not accept US Pay Pal or US credit card.Had to do a direct wire transfer from my bank.It was a bit scary sending money to someone you don't know. The shipping and tariffs were more that the cost of the tires. Less that $150 each, tires +shipping+tariffs .Cost would vary by cost of the tires at the time and shipping costs.
