Just got Pirelli Scorpian AS Plus 3 installed on my 2013 last Fri and so far so good! It handled heavy rain in Northern California quite well last weekend. It is a tad better than my previous Michelin Premier ride-wise.. tad quieter and softer. The Michelin set worn out fast.. 40K miles or less, quite disappointing and hoping this new Pirelli last longer.

I'm glad you like them. I think they are great tires for our RX. Yes here in Socal had crazy rain too, and the handling was great.
I think some people who did not like them had the older Scorpion model tires. These Scorpion AS Plus 3 just came out about a year and a half ago.

I have never been able to include "Pirelli" and "long-lasting" in the same sentence. I had a set of Pirelli tires back in the mid-1980s and another set in the early 2010s and neither set made it to 20,000 miles. Sure hope you folks have a better experience with yours.

Last longer than 40k miles? That's not wearing fast at all. Is pretty good actually. I always rotate tires and have them inflated properly and the best I could get in a sedan was 50k. So for our RX's and all its weight, 40k is pretty good. My current Michelin Defender are half way or more after 29k. I would like something more comfy as this ones are quiet but make me feel even the paint on the pedestrian X-ing.
When time comes I will consider the Pirellis or even Yokohama (they typically are comfy but don't las as long)

The mediocre Kumho Solus KL21 tires that had just been installed on my wife's 2015 RX350 when we purchased it in late October 2018 did 48,500 miles before I replaced them with a set of Continental CrossContact LX25 tires in late August 2022. The Contis have a 70,000-mile treadwear warranty. I do not expect to get the full 70,000 miles on this relatively heavy vehicle but I do expect to get at least 55,000 to 60,000 miles. Time will tell.

I wish you well with these tires, the tech on them is pretty interesting but after about a year and a half of use the tires provided for a terrible ride.

I really like the set of TOYO Celsius SUVs on my 2015 RX350. Feels and rides better than it has in quite a while.

Just swapped out my Michelin Premier LTX's with Goodyear Assurance Comfort Drive's. Luckily I was able to try them out in the rain yesterday since we were getting a pretty good amount here and I have to say I was pretty surprised just how well these gripped the road. Only time will tell how well they hold up though and how good the ride is. Funny enough the most comfortable tires Ive driven on with my 450H were some super cheap budget tires lol

For those of you that bought the Michelin CrossClimate2 tires for your RX350, how are they holding up ?
Are they quiet ?
Would you buy them again ?

Holding up very well!
I love them..

Not only would I, but I now put them on both of my daughters' AWD rav4s. One works in Park City nights as a bartender and lives here in SLC with us, so often late night drives home over a snowy pass and canyon and said she drives carefully, but never even a slip. And this has been a literal record snow year here.
We were worried about the noise with the unique tread pattern, but they are the same as any other tires we have had. These drive just great the rest of the year even in Moab and so Utah desert heat highways.
If you don't have to deal with any snow there might not be any need for these, but if you do then they are an amazing alternative to dedicated snow tires that just happen to be great tires all year long.
See the comparison chart below. CC2 is almost the best of all worlds. This is almost tire magic...

I am running Yokohama Advan Sport A/S+ tires on my 2015 RX350 AWD. The tires are very quiet and handles well in the rain and light ice in my area.

I put Cross Climates on my 2014 RX350 about 10.000 miles back and they are doing great. Noise level is not a problem and they are so good in the rain that you would think the roads are dry.. Some will complain that the ride is stiff but that is what I was looking for.

Thanks to everyone that answered my earlier question regarding the Michelin CrossClimate2 tires.

We purchased a new set of Michelin Latitude HP Tour 101V tires from Costco a couple weeks
ago for the car, and she hates them. These were supposedly the same tires that were on the car when we purchased the car (Certified/PreOwn 2015)
in 2017. Apparently NOT the same. You definitely can hear the road noise, and she claims the car doesn't handle as well.
Costco is giving us one shot (under their 30 day warranty) to swap out the Latitude HP tires. We are now looking at replacing them
with either the CrossClimate2 or the Primacy A/S. Thank you

Does anyone run all terrain tires? I've been traveling some back roads recently that can barely be classified as a road lol. Jagged rock roads, dirt roads, gravel roads and mud. Taking off the winter tires soon and was thinking to put a set of geolandar A/T's on for the non winter months as they seem like a nice entry into all terrains without going overboard. Highway and normal driving supposedly offer a fairly nice ride still. I'd estimate that I drive 80% normal roads and 20% basically offroading.

Edit - Decided to jump on them. Should ship out this week so if anyone is interested in a A/T tire on this vehicle(specifically this geolandar I guess) let me know and I can update with initial impressions.Been running scorpion all seasons and blizzaks for the past few years.
