I had the 888s on my V Star 1100 and really liked them. The rear tire had about 16,500 miles on it when I traded the bike in for my Street Glide. The tire was showing very little wear at 16,500 miles. The tire was a 180 and I ran it at 48psi (cold). I know the V Star is about 200lbs lighter but the 88 would have easily went 20,000+ miles on that bike. I will most likely go with the 888 tires on the Street Glide when it comes time for new tires. The V Star had Dunlop 404 tires on it and the back tire was a slick at 8000 miles.

 

I believe tire pressure and load rating vary with same model of tire. My 02 Ultra has a 72 & 74 load rating. I think the new Ultras are a little heavier. The max pressure stamped on the side of both my tires is 40-PSI. I road a 300 mile trip this weekend, 2-up loaded with gear, and really like how these handled. Had 38 in the front & 40 in the back. I would be extremely happy if I got 16,000 miles out of them. Read some negative feedback about tires manufactured in Brazil; no problems with mine. If I had to find a fault it would be the ridged sections on the side walls where the Metzeler logo is; collects dirt and hard to keep clean. The 880's have smooth side walls, wonder why they didn't make the 888's the same way.

 

It is designed that way to reduce air harmonics noise (howl)
