I have a 2013 roadglide ultra, but i recently added the 19" front cvo agitator wheel and the 18" rear. My book from harley has air pressure listed for different size rims. For those are you with a cvo with the same rims, what does it say your air pressure should be set at. I don't wanna go off the max pressure on the tire, what do you run. by the way i tried searching this and don't know why it hasn't come up, it had to have. Thanks for your input.

 

Book on my '15 FLHTKSE is 36 front and 40 rear.

 

Thanks but i think your stock is 17" front and 16" rear, so different. I am looking for the air pressure on the CVO road glide that has the 19" agitator front and 18" rear.

 

Not sure why you wouldn't want to take the tire manufacturers recommendation. I've found the max tire pressure works the best for a fully loaded touring bike and helps minimize the cupping which happens inevitably on the rear tire, particularly when riding assertively in the twisty's. I'm talking about Dunlops mostly, although had a similar issue with Metzeler tires. The factory recommendations are more for rider comfort than performance IMHO.

 

I have been told a few times from those in the know in the tire industry that you should not run the max pressure that is on the side of the tire. Tire will heat up and can go beyond that pressure. I had this happen once on a mountain bike, i ran the air pressure listed on the side of the tire, when it got heated up and the air expanded, i blew the tire right off the rim, throwing the wheel out of true. i know there are tons of road glide CVO owners on here and have the number i am looking for. I wish harley did what other manufactures do and post the owners manuals online.

 

I run 36 front and 42 rear.

 

Because MAX pressure is only for MAX load. That is why the tire manufactures say to use the vehicle manufacturers recommendation. The tire manufacturer DOES NOT know the weight of the vehicle it is being used on.

 

I got a chuckle at your expense. lol While I am not a tire expert, I find that comparing a light weight mountain bike tire and a heavy touring motorcycle tire to be like comparing night to day. Since you didn't say (and an honest question here) are your people "...in the know in the tire industry..." talking about bicycle tires or motorcycle tires? are the tires on the wheels OEM HD or aftermarket tires? I would think that if your ...in the know..." folks are such motorcycle tire experts, they should be able to guide you on this topic.


That said, the roads I normally ride are far from smooth and full of spleen buster type of bumps and G-out undulations. I usually run max or near max pressures all the time and I have never had any issues with tires blowing out. I have also found that when running near max pressures my tire wear has been increased. I had 26k on the stock front and only replaced it because I was going on a 5k trip. Got 20k out of the stock rear.

 

Pressures per the owners manual are Front-36 Rear-40

 

Thanks i was close, i was running 36 front and 42 rear. Thanks for your help in finding that answer.
