I recently purchased a X5 and had the tires replaced. I am not 100% on the mileage as they were recently replaced before I received the car.
1x Bridgestone Dueler H/P Sport RFT - 275/40/20 - $50
1x Sumitomo HTR A/S P02 - 275/40/20 - $50
2x Bridgestone Dueler H/P Sport RFT - 315/35/20 -$100 each
I will have to get a new thread gauge (someone stole mine) and will have pictures of thread depth later this week.
I will have better pictures this week.
