Nothing negative, but the Michelin Commander II has been great in the rain. I feel really confident riding with it.

 

So after reading all of this are they good for a Ultra and other heaver bikes.

 

I would say get Bias for sure for the added weight, but might also add would you get the benefit of the sportier tire on the big Ultras? I would think on those big highway Cruisers you might want something with better wear capabilities and a flatter center patch. I've not heard of anyone running Cruistecs on the big cruisers, but that's' not to say it can't be done.

My two cents . . .

 

9,000 miles out of factory Scorchers is unheard of. That must be a world record, lol. When I had my 2018 FLFBS the front Scorcher was shot at 3,900 miles (7 months of non-aggressive riding). I replaced them both with Cruisetecs and it was a huge improvement in ride, handling and lifespan. The Michelin Scorchers were absolute s#%t in my experience.

 

Mine were done at 5200miles, but 3970 miles were before I owned the bike.
I have over 7500 miles on my bridgestone set and they're getting close to done. Rear Battlecruiseh50 is pretty evenly wearing with one side being slightly more wear than the other. The Adventure A41 is worn nearly to the wear bars on the shoulders because of how much I corner, but the center tread easily has thousands of miles left on it before needing to be replaced. If you're not a canyon carver/Twisty enthusiast the A41 is a phenomenally long life front tire. But if you ride twisties a lot you will wear it out quickly.

I'm excited to see how these Metzler tires shape up next year.

 

Pst….. I’ve got nearly 12000 on my FXLRS, did I win a prize?

 

Nah, the m8 fat boy is know for being a tire destroyer.
Most people are averaging around 6500miles on the stock scorchers.
Not exactly sure why the fat boy tears tires up, but its a downside to owning a fat boy.

 

We run them two and fully loaded without a problem.

 

If the bike came with bias ply tires and you switched to radials, did you run placard air pressure?

 

Yes.
Tire loading is determined by the tire, not the bike weight.
If a Radial is rated to 84V, regardless of bias or radial, it's designed to handle that level of weight.
