whats the offset on the rims



looking for new rims and tires for new p700 (soon)

 

To the best of my knowledge, they are

front 12x6 4B + 2N 4/137 10mm
rear 12x7.5 3B + 4.5N 4/137 10mm

12x6 means 12" dia, 6" wide
4B + 2N means 4inches wide from plate to inside of rim (bell), and 2 inches wide from plate to outside of rim (nose).
4/137 means 4 bolt on a 137mm circle.
10mm means the lug bolts are 10mm.
