I have taken a set of Metzler Roadtech Z6's off my wife 2006 FJR

The tires have according to Pac Yam about 60% tread left

The sizes are front 120/70 ZR 17 and rear 180/55ZR 17

We are off to Colorado, LA, Mexico and then plan to ride home via Mexico.

Rather than put fresh rubber on mid trip she is starting out with fresh tread in Vancouver.

We live in Kits.
