The Armstrong Tru-trac SU Flex is a 3PMSF-marked tyre for passenger cars. Its supplier has registered it in the EU product database (EPREL) in 13 sizes (13 registrations including load and speed variants), for 15″ to 19″ rims.

How it compares in its sizes
We compared each size with all other winter and 3PMSF tyres of the same size and class in EPREL (13 sizes had at least four rivals). A size scores when its label is at least as good as 75% of them.
Strongest point: fuel efficiency. Weakest point: wet grip, where most same-size rivals do as well or better.
What the label means on the road (215/65R16)
Example: the 215/65R16 size, compared with the 766 other winter and 3PMSF tyres registered in this size.
Wet braking from 80 km/h
≈47 m with class D, against ≈41 m for the most common class in this size (C).
Fuel efficiency
Class C, the most common class in this size: no difference to the typical tyre.
Rolling noise
71 dB against a median of 72 dB in this size (1 dB quieter).
Estimates from the class ranges in Regulation (EU) 2020/740. A label class is a range, so a real tyre can sit anywhere inside it. Every 3 dB doubles the sound energy.
All 13 sizes
The small figure under each class is the share of same-size, same-season tyres this size matches or beats (“–” when fewer than five tyres share the size).
