‘Professional Off Road’ Tyre
COM 316
"Off-road professional tyre" is a sub-group of special use tyre primarily used for servicing in severe off-road
conditions
ETRTO proposal
" Professional Off-road tyre" is a special use tyre primarily used for servicing in severe off-road conditions,
and which has all of the following characteristics:
For C1 and C2 tyres :
i) A tread depth ≥ 11 mm
ii) A void-to-fill ratio ≥ 35 %
iii) A maximum speed rating of ≤ P (with sticker on dashboard for vehicle having a max speed above
150km/h)
For C3 tyres :
i) A tread depth ≥ 16 mm
ii) A void-to-fill ratio ≥ 35 %
iii) A maximum speed rating of ≤ K (with sticker on dashboard for vehicle having a max speed above
110km/h)
Marking: “POR”
Rational:
As per spare tyres’ types that are type approved at the min speed of 120km/h (L) even if the in use max vehicle speed is
fixed at 80km/h, for C1/C2 is proposed P (150km/h) and for C3 is proposed K (110km/h) in order that the speed rating
for tyre type approval is above the in use avg. max vehicle speed defined at National level, assuring an appropriate level
of safety in case of misuse..
qualche idea su come fare lo sticker
