True I got 13k+ out of my summer ones, poor alignment and all. all season should have even more life than that!

 

Location makes a big difference, as well as ride and sportiness requirements. If I wanted a cruiser where comfort is paramount I'd go for the Primacy Tour A/S. Just bump them up a few PSI to make them crisper.

There are more options and more to say when you reply.

 

The AS4 is a great tire if you can get it to balance out. 3 of my 4 new tires had excessive roadforce and same happened with warranty replacemennt. Not uncommon, so much so that I tossed in the towel and went back to conti. Never had this issue in 20 years of owning michelin summer tire like mpss and mp4s

 

Ah, but they did - Starting in 2024, the first LCs that came with the Michelin PSS5, were specifically designed for the LC. However, IMHO, they were designed with a side wall that was not stiff enough. They also did the same with the RCF and the PS4S. The tires designed for the two Lexus vehicles were rated with load range SL (Standard Load). Every other manufacturer (ie, Porsche, BMW) with Michelin tires designed in collaboration with Michelin uses a tire with an XL (Extra Load) rating. Michelin makes five size 275/35/21 PSS5 tires for different Manufacturers. I have listed them below. Notice the second tire on the list rated @ 99Y, that is the Lexus tire rated SL. The other four for other manufacturers are all rated at 103Y, or an XL rating.

This is excellent information. Thank you.

Edit: I noticed this SL/XL offering difference when I ordered M PSS rear tires for my AMG. There were two 19" tires same spec but for the load rating; at that time the same price. The XL was MO meaning that it was Mercedes specified. T'Rack made sure I got the XL.

 

Are you saying they were unable to be Road-Force balanced, or they wouldn't balance using the standard method?
Not sure the tire shops in my small MS town offer Road-Force balancing; I've never asked because I just recently became aware of this method. Worth it?

Sadly my 24 came with the Dunlops instead of the PSS5. 6/32" after 9k miles, though at least they're wearing evenly.

 

My '24 came with the Michelin Pilot Sport summer tires and I was down to 6/32 after 6K miles when I put the Pilot Sport All Season tires on last month. I will probably give them another 2-4K miles next summer before sticking with the All Season tires year round. Seriously doubt I will get more than 16-20K out of the All Seasons. Part of my problem is all of miles are in town......very few highway miles. I figure tires, oil, and premium gas are just part of ownership and I knew full well going in they would all be routine expense that I was not going to worry about in the least.

 

This is a rather long thread going back to 2017, so my questions may be answered somewhere back. I still have the original OEM run flat Michelins on my car and at 5/32 (and 5 years) they are due for replacement. I realize there are a million opinions when it comes to this subject, but I will ask anyway.

1. What is the general opinion of ditching run flats for conventional tires? I did it on my Mercedes and the ride was way better. Of course the downside is when you get a flat...and while I am capable, I am not one to pull a tire on the side of the road with a patch kit..lol I have not had a flat in 20 years...but just this week had a nail in my rear tire (slow leak...)

2. I am a gentle, touring type driver and see All Season tires as the preferred option for longer term wear. Prices are all over the place for 21" replacements. I have always seen Michelin as the top tier. Going into 2026, any recommendations on the latest available 21" tires?

Thank you

 

Mich all season pilot 4AS. great tire, longer tread wear than the RF's 255's on the front 275's on the rear. not much change in size, it that's what u prefer

 

Does anyone have any thoughts/experiences with Michelin Primacy Tour All Seasons? They seems to have similar specs to the Pilot Sport 4 All Seasons; the main difference seems to be the speed rating (149mph for the Primacy vs. 186mph for the PS4). Thanks!

 

This definitely has been a popular topic. Many LC 500 owners have been very pleased with the higher quality all season tire options.
Two mentioned quite often are the Michelin Pilot All season and the Continental DWS All seasons.
Longer wear.
Less road noise.
Improved ride quality.
Maintains very good performance parameters.

"■Replacing tires Make sure that all tires are of the speci fied size, brand, tread pattern and total load capacity. In addition, make sure that the tires are inflated to the recom mended tire inflation pressure level. The ABS, TRAC and VSC systems will not function correctly if different tires are installed on the vehicle. Contact your Lexus dealer for further information when replacing tires or wheels. ■Handling of tires and the suspension Using tires with any kind of problem or modifying the suspension will affect the driving assist systems, and may cause a system to malfunction. "

So is this just a statement to cover liability issues, commonly known as CYAs or a valid safety concern?

 

Thank you for the advice. I plan on sticking with Michelins in the exact same size as OEM. However, I will most likely go to standard versus run flat tires and do the Pilot Sport All Season. The tread pattern will be slightly different than OEM, but that should not make a material difference. The sticker calls for 33 psi all around and there should be no reason to change that.
