Strange claim. Why not?

From Federal's web-site:

"Formoza FD1 uses Federal's latest technology, TTIC, to take everyday
driving to new heights in performance and comfort. High stability, large
grooves for excellent water evacuation, maximized wet and dry performance
combined with low noise levels provide for a comfortable ride. The Formoza
FD1 was engineered with your everyday driving needs in mind."

Note - "everyday driving".

Merely pointing out that these tyres are not marketed as 'winter tyres'.

Peugeots, like most French cars, used to be renowned for ride quality. I
once owned a 309 - and that had a superbly comfortable ride. Sadly, like so
many other manufacturers, everyone now (with the notable exception of
Citroen) appear to want to emulate BMW and produce 'sporty' cars with
over-firm seats and a hard ride.

I recently test drove the current Renault Laguna. The seats were appallingly
hard - whereas in years gone by Renault were well known for the 'armchair
comfort' of their seats.
