What are pros and cons of directional tires?

Answer 1

"directional tires" refers to tire with eitherasymmetrical or rotational tread patterns.

Pros of rotational tires:

1) generally better resistance to hydroplaning than traditional tread patterns

2) generally better stopping than traditional tread patterns

3) generally better heat dispersal than traditional tread patterns

4) typically look pretty nifty

Cons of rotational tires:

1) cannot "cross" during tire rotation

2) if used for a full-size spare, likely to lose benefits in "pros"

3) Are more likely to be "performance tires" (check with your tire seller) with a shorter expected tread life than some other tires. This is not always so.

Pros of asymmetrical tires:

1) Typically better cornering stability

2) Allows for multi-compound tread for reduced shoulder wear (longer tread life at the edges) and better temperature control

Cons of asymmetrical tires:

1) must be replaced exclusively in pairs (axle sets) to prevent 'tire pull'
