Plan on going with Pirelli night dragons on my 12 FXDC.

Front 90/90h/21TL
rear. 180/60HB/17.

The alpha characters throw me off as there's another option for both tires in the same size. I did a little research and I believe the above are correct. Here's the alternatives.

Front MH90H/21
Rear 180/60B/17

 

FXDC is a Super Glide? Unless you installed a 21 inch front wheel on your Super Glide, you should have a 19 inch wheel and the correct tire size would be
100/90-19. This is the stock tire size for the Super Glide and Street Bob.

If you want to go a little bit wider, you can get a 110/90-19 tire, that will also fit.

Also, the stock rear tire size is 160/70-17.


The 180/60HB/17 tire will fit too, but you will have to make sure the wiring for the turn signals and tail light are tucked in good or they will get torn up by the tire.......

Cant help you with the front but my NightDragon rear is labeled "180/60B/17"

Not sure of the difference in the 60B and the 60HB but mine fits a '09 FXD with no mods or issues.

 

I am at least that smart. Lol. I should have said something about the conversion. Sorry Doing a wide glide conversion.i believe the H stands for the speed rating and the B means belted. Just didn't know if there was a reason to go with one as opposed to the other

Thams guys
