MICHELIN A better way foward

MICHELIN's Light Tire Technology (LTT) helps you save over 2LBS over rival tyres.

What is MICHELIN Light Tire Technology (LTT)?

LTT marks a fresh approach to sports tyre design by simultaneously optimising the construction, profile and constituent elements of the tyre.
Its mission from the outset was to save weight.

LTT employs advanced materials like aramid fibre as used in the aerospace industry.

The thickness of the tread is unchanged!

Shaving 2lbs off the weight of a modern sport bike which tips the scales at 400lbs might not seem such a big deal.

Yet it is, since the saving in question concerns a part of the bike that is not covered by the suspension. So-called unsprung weight. In other words, the lower a bike's unsprung weight, the easier it is to switch from leaning into a right-hand turn to leaning into a left-hander. And vice-versa.

Gyroscopic forces mean that running a tyre which is 2lbs lighter is equivalent to saving 6lbs on rims or 8lbs on brake discs.

The inertia of the tyre and wheel assembly creates a gyroscopic effect.
The weaker the gyroscopic effect, in particular for the front tyre, the better the handling. From a gyroscopic point of view, the same mass has a larger negative effect on handling as the radius increases. This is why it is more efficient to reduce tyre mass than wheel mass as the radius of a tyre is larger than a wheel. As an example:

- Saving 2lbs with a set of tyres has the same effect as saving 6lbs of wheel mass
- Saving 2lbs with a set of tyres has the same effect as saving 8lbs of brake disk mass

A lighter tyre/wheel assembly which readily moves in response to road bumps will have more grip when tracking over an imperfect road. For this reason, lighter wheels are often sought for high-performance applications, as is the case in motorcycle competition with magnesium wheels. High unsprung mass also exacerbates wheel control under hard acceleration or braking.
The vertical forces exerted by acceleration or hard braking combined with higher unsprung mass can lead to wheel hop, which compromises traction and steering control.


Gyroscopic effect is the generation of resistance to directional change of a wheel turning on an axel.
