If you have the 1500, the lug pattern is 6x5.5. If you have the 2500, the lug patternis 8x6.5. Watch out for the backspacing or offset. The 1500 looks like a high offset (around 20-30 mm positive offset). If you get your offset too low (0-10 mm), your wheel/tire combo could stick out too far for your liking.....
