I believe it is 46/41I guarantee your tire pressure is low. That means you're wasting gas and wearing out you tires.
As others have said, tire pressure increases as temperature raises. That is because the air molecules, like everything else except water, expand as they heat up. Bigger molecules in the same size space equals increased pressure.
That is also why you need to add air to your tires when they're cold. The recommended air pressure is 36 front and 41 rear. The best time to check them is after they've been sitting for at least 3 hours after being ridden.
Temperature's affect on air is also the reason you have add air in the fall and take it out on the spring.
Some people use nitrogen instead of air in their tires. Nitrogen is not affected by changes in temperature as much as air and it doesn't permeate through rubber as easily as air either. However, it is a lot more expensive than air. And if you need to top it off, it's a lot harder to find without going back to the place that filled your tires.
I recall a couple of years ago someone posted they called and spoke to a tech at Dunlop America. He posted the response on here but good luck combing through the archives finding it. If I recall he said that because of the rake Dunlop and Indian both determined that 46psi was the best arrangement for the Springfield. Who knows? I run mine starting out at 46f/40r and over the next couple of weeks it bleeds off slowly like other bikes on here do, and I don’t bother filling it back up all the time and just live with it. Because the Springfield rides so much better than my Road King, which I swap out every ride, I can hardly tell any noticeable difference in the ongoing lower tire pressure issue.Has anybody ever gotten a sensible answer why the 16" Springfield front tire recommended pressure is 46 psi?
