2nd set of Alnezas we put on our Acura. First set (2009-2012) lasted 54,000 miles - not bad. This set 2012-2014 lasted less than 35,000 miles.
Quality has declined. Switching to Goodyear to see if they are better.
I originally replaced the OEM Michelins, which rode like wood and had poor wet grip, with the Yoko Avids. The Avids had slightly less dry grip than the Michelins but 3 time the wet grip, and the ride is a bit more supple. I'm on my 2nd set of the ENVigors, which work like the Avids. I do not get a lot of mileage out of them but then I tend to drive hard, and routinely slide all 4 tires. If you think I'm exaggerating, I'll take you for a drive. I run my pressure up at 40 PSI (the Yokos have a much softer sidewall than the Michelins) to get a little less sidewall flex/roll, and they still ride great. Road noise? Well, I guess RDXs are built better than the cars some of the other commenters drive, 'cause it rides nice and quiet with these. There aren't that many options in this tire size, and Yokos cost 2/3 what the Michelins cost, and on par with most of the competitors, so "spending a little more for more life" is not really an option. They suck in snow but any tire that works well in the dry will, it's physics, sorry to disappoint you all.
Purchased set of 275/45/R20s (set of 4) more than 16 months ago. We were a bit apprehensive about purchasing Korean-made tires, but went for it.
Seattle gets a lot of rain. The first week it rained a lot and these tires would not let our SUV hydroplane at all. Winter time - we climbed up an icy hillside (15% incline) to realize at the very top that the car was sliding towards a cliff. Walking out of the car we were sliding on our shoes down the hill. What a grip these tires have as we did not even use the chains!!! Gradually let the SUV slide down the hill on the ice.
Overall impression - very stable on hard corners going 60+ mph.
We will purchase another set after these will wear out.
