The FIA has carried out more stringent flexi tests on Formula 1 rear wings amid speculation some teams are using techniques to allow illegal movement at high speed.

Videos have emerged that appeared to show movement from the Ferrari rear wing and Red Bull front wing, therefore reducing drag.

Article 3.15 of the technical regulations says "any specific part of the car influencing its aerodynamic performance must be rigidly secured to the entirely sprung part of the car".

It adds "rigidly secured means not having any degree of freedom".

But the FIA says the wings in question are fully compliant with the current regulations.

The governing body has checked the rear wings of the top five constructors, even increasing the load by 50% to check if there was any flex above the legal load, and all were in conformity.

While the option to strengthen or revise flexibility tests exists in the regulations, the FIA sees no reason to do so at the current time.

Speaking after the Canadian Grand Prix, Red Bull boss Christian Horner dismissed any talk of the team having a wing that flexed.

"The car has passed all the tests, they've looked at all these things in great scrutiny and there are no issues," he said.

Meanwhile, the FIA has refuted claims it is close to introducing a new procedure for checking tyre pressures.

From the Italian Grand Prix last year, Pirelli introduced a minimum starting tyre pressure with measurements taken before the race.

Pirelli suspects some teams have found ways of forcibly lowering their tyre pressures between the moment checks are made before the formation lap and the actual start of the race.

Plans to change the procedure are understood to be only in the formative stages and the current systems are some way from being modified.
