Which way should this tire be installed?

Inherited a bike from a friend. I don't think he had the tires installed on the wheels in the right direction.

Most newer tires tell you which way the wheel rotates. On these, however, there are no arrows on the sidewalls.

Judge yourself -- right or wrong direction? I think personally it should be reversed?

The other way. Pointy tread should be rolling forward (in theory). However, if there are no directional arrows on the tire it's not the end of the world if it is mounted backwards. The way that it's mounted now will create more wind resistance as the "cupped" segment on the lugs will catch air. If mounted properly, the pointy section will more easily cut through the air.

I think it's on backwards. With that tread pattern, you would be leading with the weaker narrow "sharp" parts of the tread blocks, which might lead to excessive wear.

In the end, I doubt it matters much, but it was probably intended to be the other way around.

Might help to have that "scooping" action in mud, right?

I think it's currently mounted backwards. The point in the middle of the chevron is supposed to hit the ground first, squeezing the water out. The other way around would capture the water. In theory anyway - personally I don't think it matters because bicycle tires do not hydroplane.

They can if you go fast enough. Of course, 'fast enough' involves speeds exceeding 60-80mph, depending on how much pressure you have in your tires.

That'll just load up the tire with mud, while digging you deeper into the mud. You want the point first in mud. Hint: look at tractor tires.

It probably would do better backwards in mud, but it's not a tire that's designed for mud.

I have a set of tires with a V pattern and the direction shown on this bike is how it should be mounted on the rear but the other way (as all of you have been suggesting) for the front.

If it matters, there is an arrow molded in the sidewall of directional tires.

Lacking the arrow it may not matter.. to the design, just to the user's aesthetics.

So what brand and model are these? Just curious. I doubt that it would matter much which way they are oriented.

I don't think it makes any significant difference for those tires. I always mount them the other way, because I like the way it looks.

With MTB tires having a more pronounced tread, some mount their tires as you have for better braking traction, and some like it the other way for better accelerating/climbing traction.

For bicycles it really doesn't matter where you point the thread. You are not going to go fast enough to hydroplane.
