I do lots of kilometers per month to go work, 100 per day, mostly highway. My previous tyres were Goodyear's efficientgrip performance on the front (arond 30k km wear) and michelin primacy 3 stock tyres on the back (70k km wear). I have to say I noticed the car runs smoothier than before, and also less noisy. Good overall grip, and hope it lasts as long as goodyears. Very happy with the tyre, seems to be a very good all-around tyre. My sensations are better with these Bridgestone's than the previous Michelin and Goodyear's.
