PSO are specialists in HGV tyre regrooving equipment. For over 60 years, we have been developing our tyre regrooving expertise, and are now one of the few world-renowned specialists in the field. Let’s have a look at some of the key dates in the company’s history.


Pneu Service started out as a family business founded in 1946, and is now headed by the 3rd generation of men and women working for the success of the company. At the beginning, the company was no more than an ordinary garage which fixed mechanical problems and changed tyres, but even then Pneu Service stood out by manufacturing axles and wheels for agricultural vehicles.

With the rise of road transport, new challenges appeared. How could you make the most out of a set of HGV tyres, and what to do with all of the used tyres that were no longer useable? Tyre regrooving was a solution to both these problems. This is why Pneu Service launched their regrooving operations, creating an ergonomic aluminium handled tool in the 1950’s which has been slightly improved, but remains much the same as the first models.

  • 1960
    Perfecting our cutting-head
    At the beginning of the 1960’s, our tool was on the market and had already made a name for itself. What set it apart were the cutting-head, which over the years would be lightly modified, but still remain instantly recognisable.

  • 1977
    “Pitet” models started to attract global recognition
    Stepping into the company after gaining valuable business experience in a major French industrial group, Mr. Jean Paul Pitet (2nd generation) brought an entirely new management system to the company. This was the moment that our products rose to prominence, eventually being recognized and adopted by everybody in the industry, such as Michelin (who still call our tools “Pitets”) and a number of other major groups. This recognition put us on the road to success. Ever since, our regrooving tools have kept improving, adding new features such as electronic heat management, and becoming increasingly effective and comfortable for the user.

  • 1980
    The arrival of “double-sharpened” blades
    The 1980’s saw the arrival of “double-sharpened” blades, mass-produced for “hand-designed” machines.

  • 2000
    PSO, a “cutting and heating” equipment specialist
    In 2000, Pneu Service sold off the automobile service activities in order to focus exclusively on “cutting and heating” equipment. We changed our name, becoming Pneu Service Outillage, then going under the acronym PSO.

  • 2005
    the 3rd generation arrives, ready for brand new innovation
    This was the year when, following his degree in international business, Olivier Pitet (3rd generation) entered the company. With this arrival, the company was driven to maintain its level of excellence and offer products and services of the same quality as what had come before. And now we produce thousands of products and distribute them to clients on five continents.

By increasing the useful product life of your tyres (regrooved tyres can roll 25% further), you’ll save money by buying fewer new tyres and also by consuming less fuel.

In fact, regrooving helps protect the environment because:

transporters release less CO2, fewer tyres are used and discarded and fewer natural resources are consumed.
