Wink Check Your Tire Pressures!

Everyday I see bikes that have low tire pressure. When I ask when's the last time the rider checked it most cannot remember.

Because they hold a smaller volume of air than car tires, bike tires are more sensitive to volume loss and temperature changes.

Especially right now with the temps moving 20-30 degrees a day, pressures can vary 4-5 psi.

Check your tires at least every 2 weeks, and set them cold.
For most street sportbike riders 36 front and 34 rear or 36 front and rear are good pressures.

If in doubt, consult your owners manual.

Proper tire pressures mean longer tire life and better handling.
Get yourself a good quality pencil gauge. Not the .99 cent one from Walmart, but a $5-6 one from an auto parts store or bike shop.
Make sure it has an accuracy range within 1-2%.

One of my pre-ride checks is tire pressure. Every ride...unless I was just on it the day before and the temps hadn't changed.

My front tire loses pressure fairly uniformly while my rear tire looses almost nothing after several months. I check my tire pressures once a week and if I notice my trip counter increses by .2 miles for my round trip I know I need to fill it up (usually about 2 lbs. under).
Also lube your chain. I see a lot of rusty chains. Mine gets cleaned and lubed once a week and after riding in the rain.

Great advice and it goes for your 4 wheeled vehicles too this time of year.

I found a small pencil gauge that has a tiny magnet on it at O'Reilly's for a few $$$. Rides on the front part of the tank inbetween the frame mounts, never had an issue with it being in the way or falling off.

I check the GF's tires in her truck once a week. They're never right. BUT, we've never had a tire fail *knocks on wood*

Good thread, Patrick. Those who care... share.

Patrick is right. I was guilty as well, until I noticed it felt like my bike wanted to dive into turns at neighborhood speeds.
After setting tire pressures it was, once again, neutral like it should be.

I called you about doing fork seal my front end felt so bad and the bike was overall sketchy, half recommended tire pressure tends to do that.

Every ride gets a cold tire pressure check. I also use a tread gauge before and after my longer rides. Center-stands are also nice for checking hop & wobble.

I've always ran my tires a little under to increase the contact patch for traction, a little softer on the bumps, and so the very top of the tire don't wear as fast.
Also I tend to "warm up" my tires quickly and have always been told to "let a little out" by the racers....
I get about 9.5k outa the front and 3.3k from the rear- is that bad?
125HP ish...

depends, did you just top off the summer air, or did you deflate and reflate properly with just winter air only?

Are you saying they were 5 psi under or that they were at 5psi. If it were the former, good catch as the handling will improve. If it was the latter, and you couldn't tell this as soon as you sat on the bike , please sell the bike and never return to MH.
