Harsh ride, reduced fuel use claims false. This is third set of tires I have had on my 2002 Subaru Lancaster 2.5L. I have recorded every tank of fuel I have used in the 90,000km I have owned it. The first set of tires were Bridgestone snow tires, followed by Firestone TZ 700's then the Triplemax fuelsavers. The best (including best handling and riding)were the FirestoneTZ700s with an average of 10.1L/100km over 50,000km, followed by the Goodyears at 10.32L/100km over 20,000km so far and not far behind the Bridgestone snow tires at 10.46L/100km over 16,000km. Disappointed.
No, this product has too many drawbacks.
