Spray Suppression Fitment Advice

Mudgaurds and Flaps

Twin & Tri Axles

If the gap between the tyres is less than 250mm, a flap on the rear mudguard only is necessary.

Flap Width

The flap should cover the full breadth of the tyre(s), except inside the mudguard, where it must cover the tyre tread(s) as a minimum.

This may be increased to 300mm for rearmost axle of Ro-Ro-Trailers

Flap Valance

Twin & Tri Axles

If the gap between the tyres is less than 250mm, a flap behind the rear most axle only, is necessary.

However, the valance must continue and span the full length from Point A (see drawing) through to the flap behind the rear most axle.

Flap Width

The flap must cover the entire tyre breadth.

• This may be increased to 300mm for rearmost axle of Ro-Ro-Trailers
