tire tread direction - Ultra 2000(6 posts)

tire tread direction - Ultra 2000treeman
Sep 10, 2002 3:48 PM
Hi everyone,

I noticed in my LBS, on expensive road bikes, that often the front tread pattern is mounted opposite of the rear tread pattern. Is there any reason for this? Usually the front pattern points "forward" and the back points "back", when looking from above the wheel. On other bikes, the tire tread matches up. Whats up with this? Thanks.
Always mount your tires so the tread touches the pave. nmMB1

Someone's idea of aesthetics, I suppose.jtolleson

The tires are non-directional and the little grooves are essentially non-functional.

Everyone has their preferred method, usually to do with placing the label on the same side and near the stem.

When you say "often the front tread pattern is mounted opposite of the rear tread pattern" I would challenge you to actually take a count. I'm guessing that "often" means 25% of the time. In other words, in a statistically random fashion. The general rule is that if a tire has a marked rotation direction, then by all means follow it. You'll not find that marking on any high end tire, because there is no directional meaning to the tread pattern. The "photo sensitive" among us will put the label on the right (drive) side of the wheel/bike. Otherwise, there is no directional imperative.
When in doubt, both should be mounted like a tractor's treadTig

From above the herring bones or V's should point forward. Back when MTB tire choices were limited, people would mount the rear tire backwards to increase loose dirt and mud traction. I don't know if it worked any better.

I bet that some of those tires were mounted backward by accident. It really doesn't matter since tread grooves have almost no function on a narrow road bike tires, even in the rain.
usually mounted so both labels are on same side (nm)ColnagoFE
