I think they will be decent (not stellar) up to 20,000 miles or one winter. That should give you ample time to shop for some really good tires.

BTW, in my latest issue of Consumer Reports, Crapstone Ecopias are not listed as a SUV tire. Even the Lexus OEM Michelins are not listed as the best tire for SUVs. I found that very interesting. Goodyear was mentioned as a good tire... There are many tires that are made for all kinds of vehicles, so no one tire brand is good for every vehicle.

My 2021 Base RX with 20" wheels did have the Michelin's from the factory. I was glad to see that. I noticed that of all the Rx's on the lot that it seemed to be a 50-50 split between Bridgestone and Michelin. I saw Bridgestone on the Luxury package models as well. I think the assembly line used whatever came in that day. Mine was a Sept. 2020 build from Cambridge Ontatio.

The problem with Michelin's that they come with 8/32" tire depth compared to 10/32" Ecopias, so you get less tread depth, but their less noisy and have better traction in the wet. They are more expensive as well.

It's not that the Ecopias are bad, its just you have to be careful when you have 4/32" or less tread depth. Manoeuvring in the wet is more difficult. Michelin's have a design feature, that lets water escape from the edges as the tire wears out whereas the water is trapped in the Ecopias and you slide if you have less tire depth.

If your not a seasoned driver, you should just avoid the wet parts of the road. Don't slam the brakes in the wet, and drive on dry part of the road. Drive slowly in the wet too.

Michelin - 8”, Ecopias - 10”??? Are you running tractor tires?

My brand new (built September 2020) U.K. RX came with Japanese-made Dunlop SP Sport Maxx 050 - 235/55R20 102V. I'm surprised to see that the tyre pressures are only 33.3 psi (2.3 bar) which seems low for a car weighing best part of 2.2 tonnes. Bizarrely, this OEM sized tyre is not available on any of the U.K. tyre places, such as BlackCircles and even Dunlop themselves!

Nice to see a full size spare wheel / tyre in the boot.

Cheers

My Ecopias lasted 30,000 km. Last year they were horrible in rain.

I bought the Michelin Primacy Tours and love them.
​​​ handling is far better, really quiet and much better traction than the Ecopias.
I'm not sure why OEMs actually install these bas5 tires on their premium vehicles.

You have this backwards. I don’t remember anyone on the forum getting more miles out of their OEM Ecopias vs. Michelins. As a matter of fact, most people have complained about the Bridgestones hydroplaning way before the Michelin tires. The Ecopias don’t even come with a mileage warranty. These are pure garbage tires for this nice of a vehicle. Ecopias belong on a Sentra, and not on any Lexus.

I had the Michelin Premiers on my Rav 4 and they are good for 50,000 minimum and handled excellent in up to 10" of snow. It had the Ecopias that I replaced quickly because of tread noise, but this post saying to not drive on the wet part of road is borderline crazy talk IMO. They are not that bad for crying out loud. . Also, slamming on the brakes is perfectly safe with antilock brake systems.

My 2 cents. Bridgestone ecopia ( or whatever its is called) are utterly atrocious. Out of 20 years of driving premium brands i never experienced anything even remotely as horrid. I so used to get what i paid for that i did not even bother to look at the tires when I purchased Rx. I guess Lexus taught me a lesson. Shame.

I did a bit of research on this as well. Picked up my new '21 RX 450H F-Sport, it came with the Michelins, I breathed a sign of relief. Car rides like a dream. According to my Costco Tire guy, they are both smooth and quiet, he seemed somewhat partial to the Bridgestones which according to him will last longer. He did concede that the Michelins were of higher quality but the less durability and higher price in comparison to Bridgestone did not justify it. He also mentioned that the Michelins are not good for very heavy SUVs (like a Ford Expedition), stick to Bridgestones for that. Based on all the feedback that I've received, I've concluded that Michelins are superior to the Bridgestones. I also had Michelins on my prior car (Lincoln MKX), they were very comfortable and smooth but did wear out well before the 60K mile warranty... and Costco "got me" with the tire rotation policy but I didn't care since I traded that car in anyway with like 1/116" tread on one of the tires... not 1/16" but 1/116"...

Default I guess neither are winners

My new RX 450h came with the Bridgestone. I guess I will not visit my son in Syracuse in the winter. I had the Michelin Premier LTX tires on my '16 Jeep GC. The pros of the tire is that when new, they do well in the snow. When worn to 50%, my 4X4 Jeep would spin and slide. I can imagine that will not bode well with an AWD system without a snow mode and 4x4 low like the Jeep. In wet they work well, even well worn. The issue is that their tread life sucks. At 38,000 miles I needed to replace them.. Michelin dealer told me that the weight of the JGC causes premature tread wear as the rubber compound is softer. I got a good close-out deal on Tire Rack, and got them again and they lasted 32,000 miles. I do regular rotations and annual alignments, so the wear was even. I'm now running Crugen HT 51 on the Jeep. My first Kumho set of tires, They are a Michelin Defender knock-off, but with a severe snow rating. The Defenders & HT51 are best for heavy on-frame SUVs and trucks. Haven't had snow yet where I live, but the HT51s are a solid tire and smooth riding with little wear after 12,000 miles. My point is that the Michelins will wear fast, but they are a good tire for the most part.

So what I’m taking from this tread is that Michelin Premier’s are the most comfortable tires for the RX, but don’t last past 40k.

There is no worthwhile substitute that will improve ride quality, handling and tread life, all tires in this size are a compromise.

255/50/20 will ride harsher, consume more fuel to gain better handling.

Goodyear Weatherreadys maybe slightly better then Michelins for wet / snow traction, but probably won’t exceed 40k either.

Default Is this a good deal on tires? Any recommendation on better ones?

I always feel uncomfortable buying tires. I have a long road trip coming up. My Ecopia tires are at 4/32 and I only have 24,300 miles. Should i be buying tires yet at 4/32 tread left? Is this a good deal? More importantly is there a consensus on which are best wearing/performing. Where I am relocating gets a little snow every year, but thats never been an issue for me, I work from home. THANKS (not sure why the print is so large???)

Five months ago I was in the same situation as you are in today. Actually I made it to 28K miles, but it was summer and they were a little under 4/32 by then.

NO, you should not launch a trip in winter in Iowa on 4/32 of tread. YES, you need to replace those junk Ecopias.

I would characterize that price as "good", not "great". I paid about that amount for a set of Goodyear Assurance Maxlife tires, on sale. I decided long ago, in conjunction with riding a motorcycle, that there are a couple of items in life that should be purchased with more attention to quality than price, and vehicle tires are one of them. It's only your life that is depending on them. ;-)

Michelins are good tires -- I say do it.
