hi guys ,got a 2010 wide glide,manual says front tyre 30psi rear tyre 40psi,dealer says36 front 38 rear,confused,so my question is who has a wide glide, and what preasures should i run?..... thanks

local dealer here said 36f and 40 rear, but yeah I noticed what the book said, Im sticking with 35-36 front, and 38-40 rear.

i know there different bikes but the road sweeper and the finger burner i run 36psi front 40 psi rear then i dont get confused when its time to check the pressure

 

36/40

36/40 looks like the rule. Trivetts say all HD's leave their workshop with 36/38 but the guru Brian Connors at Brookvale insists on 40 rear so I've gone with that.

I run 36/40 on my Softail setup for a pillion.

36/40

thanks for your help guys, magority rules, 36/40 it is

I just blow mine up until my cheeks start to hurt and cant blow anymore !!

whatever it says on the tyre is what i go with

Avon say's 37 front & 40/42 rear. I like to run a harder front tyre on a 21" wheel.

Or maybe the harder they are the more likely they are to wear quicker in the centre or grip less in the corners ? Who knows ? I've always run my 21 inch front at 30 psi and it always wears very evenly so i leave it at that. That's what the book says but, a tyre guru told me Harley like you to run em a bit low so the ride feels softer from the factory ?? I just stick with what works, if mine wore unevenly then i would chage the pressure. Back is 40 or 42.

32 / 36. Lower pressure in the rear = better traction. Too much wheelspin at 40! ;-)

I called AVON in the UK they other night and for the Venom and Venom white walls for an Iron 883 they quoted the following:Here is the information you require:

XL883/R/L Sportster/Low/Iron/Nightster year 04 onwards
Front 2.5bar/36psi 100/90-19 57H Venom (also WW)
Rear 2.7bar/39psi 150/80B16 77H Venom, 77V Venom (also WW)

Ive been having shimmy issues with the front end
these pressure have helped considerably.
Your weight will have an effect as well.
I recommend calling the manufacturer as the tyre fitter told me something completely different.
Hope that helps

All pressures recommended by tyre manufacturers are averages for all conditions, i.e. riding style, weather, road surfaces, rider and bike weight, wear, speed, etc. They are recomendations as they have no control of these variables. Example; same tyre sold in Chicago where it can get to minus 30c is the same tyre sold in Dubai which gets 50c+. Thats a big variable.

A good example is the V8 Supercars. When they start from the pits they have low tyre pressures, say around 17 psi. Once the tyre warms to optimum operating temp. for grip (cornering and stopping) and wear they are a around 32 psi. (if my memory is correct) Again the variables come into play such as track surface (abrasion) , suspension setup, ambient temperature, track temperature, amount of corners (friction, brake temp. radiating through the rim heating the tyre).

I have experimented with differing pressures on the Fatboy with Dunlop, Avon, and Pirelli. As I have no corners up here, it is always hot and the roads are abrasive, I was pretty much running in controlled conditions. I found out a few things. Running the rear above 6 psi from manufacturers recommendation will increase the wear down the middle. In my case the tyre wore out 50% (in 2500km) quicker. At recommended pressure and within 2 to 4 psi above I achieve normal wear. Running the tyre 4 psi above recommended was on hoter days as it keeps the tyre cooler (so the manufacturers reckon) Running the tyre 2 - 4 psi under is OK too and a nice soft ride with more tyre on the road. Good for wet conditions. Anything lower and you run the risk of overheating the tyre walls. (depending on how hard you ride)

Experiment 2 -4 psi either side of the manufacurers recommendation to find what works for you. Keep in mind the VARIABLES.

DISCLAIMER NOTE: always follow the manufactures recommendation
