Because it had no bearing on the question he asked.

The rest of us (me especially) just assumed it was going on a stock bike.

 

Because I didn't think people would misread my question?

 

FWIW no one misread your question.
It was perfectly clear.

The misunderstanding came when we made assumptions because we are used to people asking about what will or won't work on a stock bike.

You asked what would fit on a wheel and we were answering what would fit on a bike...not your fault.

 

Yes it definitely will... I have a Metzler 150 on my 98 OEM Fatboy rim...

 

Thanks guys!

Pleased to hear that, 124" and a 130 width tyre didn't strike me as the best combination...not that 150 is much better but every bit helps!

 

It is important to give more details, simply because with that we can give you a more complete answer and more promptly. Yes a 150/80 tyre will fit your wheel, I've done it myself, however all our older Harleys have limited clearances, especially with the drive, whether it is chain on your older bike, or belt on slightly later bikes.

So let's go back to basics, as you can answer your own question. Assuming you currently have a 130 or MT rear tyre, you can measure your current clearances between the tyre and chain, or chain guard. The actual installed width of a 150 tyre can very, depending on brand, but let's assume one that measures 150mm. That will need nominally 10mm clearance, taken from what your currently have, to work. So check your bike and ask yourself: do you have that 10mm, or preferably a decent amount extra?

Take care when selecting a 150/80 tyre, as they were once popular for a wide variety of bikes and are available in several different load ratings, also H and V speed ratings. A V rated tyre may be suitable, but will have less tread, be softer and not last long. But then with a 124" that may not matter!

 

Well I wasn't bothered about clearances because everything is 'custom' anyway so if it wouldn't fit I'd just make it fit.

All I ever wanted to know is if the 150 tyre would fit the fatboy wheel, not if the fatboy-wheel with 150 tyre would fit my bike

I'm not bothered about threadlife, most likely it will outlive the transmission anyway...

The Ness fenders are pretty wide and I can offset the trans and wheel sprockets at will so I should manage to squeeze the 150 in.

There's a 180 lurking in the rear of my mate's '78 FLH without too much bother so on my '77 FXE it shouldn't be an issue.

Dead curious to see how silly the 124" really is in the old shovel...!

 

So are we.....

 

Well, how silly is your 107"?

I take it it's more built for torque than outright power?

My engine puts out 150 BHP and the bike will be a bit lighter so...pretty stupid?
