The Scorpion STR A & Scorpion STR
tires are Pirelli's premium Highway All-Season tires that were
designed to deliver the Stability, Traction & Ratings (STR)
appropriate for today's light trucks by adapting their performance
to the needs of sport utility vehicles, light duty pickup trucks &
4x4 vehicles. The Scorpion STR tires are designed to combine a quiet
& comfortable ride along with ease of handling & year-round
traction, even in light snow.
The Scorpion STR's tread compound is molded into one of two similar,
but slightly different symmetric tread designs. The tires featuring

tires feature twin, high- tensile steel belts reinforced with
polyamide to provide strength & durability on top of a two-ply
polyester cord body that helps cushion the ride.
Depending on their size, the Scorpion
STR Highway All-Season light truck tires feature either outline
white or black letter styling. They are T- or H-speed rated (with
one V-speed rated Original Equipment application) & are available
in a wide range of 55- through 75-series Euro-metric sizes, P-metric
sizes & selected LT-metric sizes to fit 14" through 18" diameter
NOTE: The Scorpion STR in the

Scorpion ST in the 215/65R16 98H size on Volvo XC70 AWD vehicles.
