Harley Tire Pressure

QuestionI’ve got a 2011 H-D Fat Boy Lo with stock tires. Jerry “Motorman” Palladino in his “Ride Like a Pro” DVD recommends running 40 psi tire pressure in the front Harley tire to lighten steering loads and ease low speed maneuvering. The H-D owner’s manual calls for 36 psi in the front tire. Will going to 40 psi cause any problems with the front end, i.e. excess wear or speed wobble and will there be any problem with wear or damage to the front tire. Thanks in advance, Tom

Answer Tom, Over inflating a tire may cause it to wear quicker and you will typically feel more of the road because of the tire being harder. Keep in mind; engineers spend many hours studying & testing these tires and motorcycles before they resolve to a number (36 lbs). This tire pressure amount is what has been determined, to be best, for longevity of the tires, quality if the ride, and rider safety.

      Im downunder Australia. Our roads are garbage. I run Avon tyres on a 2012 FLSTC at 40 psi front n rear. I run the pressure at max pressure that is on the tyre sidewall. HD dont make tyres so i go with tyre manufacturers specs. At max pressure tyre wear is less due to less movement in the tyre wall resulting in lower tyre temps due to less friction. Less friction , less wear.

      If you weigh over 200lbs go 40 and 40… go smart… wear and tear is minimal… the big factor is do you have good tires and tread front and rear plus matching front and rear tires..check pressure each ride… winter storage tires should be on scrap broadloom vs cement… mike… canada

    I have found that running 40 lbs in the rear tire all the time works better than running 36 . My tires last longer by far .And if there is a need to ride someone on the back of your bike you are ready.

    Very good information to share. At every swap meet I have been to I see tires for sale. Use the manufacturer code on the tire to make sure you are not buying too old a tire. If you are buying just for a mock-up that is one thing but don’t buy old tires for riding. They put that stamp on the tire for safety reasons. If the tire goes away on you at speed you could be in for a seriously dangerous situation. Good job brothers!

    Jerry Palladino makes some very useful riding DVD’s. His courses will definitely make you a better rider. Though as far as upping the tire pressure to 40 in the front, I personally wouldn’t do that. Like Fix my hog said, those pressures are engineered and are best for that specific tire for handling, wear, and stopping distance. You should have no problem with low speed turns at 35 PSI

      I would guess Jerry is only advising the higher pressure on a course. Less rolling resistance = smoother transitioning from turn to turn. In addition to that there is less rebound which again provides smoother movements. Higher pressure is also useful when utilizing the chicken strip of the tire.I prefer 38 in the stock Dunlop and 39 on the Metzler up front on my 2003 Road King. I also run 40 in the rear of both brands and find 11000 miles possible with Dunlop and 8500 with the Metzler. This is mostly solo riding too. Hope this helps…

    Hi I was wondering if there was a video on the FMH Website regarding increasing the size of the rear swingarm?
    I am currently in the process of changing out the rear end 200mm wheel to 240mm on my 1997 FLSTF Fatboy.
    I have a 250mm swingarm fat tail kit with no sprocket on the transmission drive extention/spacer. I was wondering how to work out the spacer size to match the new rear wheel sprocket? I was also wondering how I go about installing a new srocket on the new shaft. With the old sprocket 24 tooth I was looking at changing to 23 tooth for a bit more torque on the lower end speed.
    What do I need to look for when ordering a new sprocket in regard to the offset? Can you please help me out and get back to me asap please. Thank you for your time look forward to hearing from you have a good one.

      Hi Will, Sorry we do not have a video on that at this time. Did the kit come with manufacturer recommendations?

    also remember that recommended tire pressure is for the OEM tires , if you use another tire 36 psi may not be correct for that tire . Example if your tire is rated at 600# at 36 psi and you replace it with one rated at 600# at 45 psi , then it’s obvious that 36 psi is not correct pressure with the replacement

    Looking for the best air pressure for a 2009 HD Softail Deluxe? I know it’s recommended to keep less air pressure than what’s stated on the tire.

    The tire manufactures also take into consideration that a rolling tire will get hot & the air will expand in the tire, I use & recommend air pressure that is stamped on the tire.

    2005 Heritage Softail with Michellin Commanger 2’s. I weigh about 220 and ride 1 up 90% of the time. I randomly have another 20+ lbs of gear in my saddlebags for work/trips. I’ve been running 36 front, 40 rear but an HD service manager recommended running both higher because of the Commander 2’s. The center is definitely wearing quicker on these boring straight roads. Normal riding, I’m fine with a few bumps if it extends life. Any input?

      Hello Steve,

      Here is what our experts had to say regarding your question:

      If an engineer has proven this to be true, then we would say that it is likely true. But if that was the case, Michelin would likely specify “45 lbs max cold” on the side of their tires.
      We recommend 36 front & 40 rear.
