Quiet tires for my '09 LS 600h
Hi,
My current tires are: 245/45 R19 102Y
Front: Dunlop SP sport Maxx (67db)
Rear: Goodyear Eagle F1 (70db)
I want the quietest tyres possible, i am not interested in handling.
Is there a more silent tire than my Dunlop's?

Consumer Reports is a good source of tire ratings based on scientific measurements and noise is one of the items for comparison.
The sound levels that you cite in your comment are meaningless without some context. I think advertisers like to use those kinds of numbers to help fatten out their ads.
When I see inputs like yours regarding "quiet tires" I wonder if this is not more of an issue about your car's ability to prevent outside noise from entering the cabin. If your car has good "noise isolation" characteristics then the noise that the tires make is usually a problem for others, but not for you when you are in your car with the windows up.
There was a trim defect on some of the LS460s and LS600s - yes, the LS600s were included in this problem - that caused the noise isolation to be significantly lowered.
You should look into this DIY repair to see if it might help your car: https://www.clublexus.com/forums/ls-...noise-fix.html

I have tested the trim defect, and yes, the windnoise was less when i used masking tape on the sides.
But unfortunately i still hear the tires, even at low speeds, depends a bit what sort of road i'm driving.
I'll check consumerreports what's the best tire for me.
Thanks for the link to the trim defect, my car is still under warranty, perhaps the dealer will fix it for me.

The trim defect is typically bilateral. Be sure that you tape both sides at the same time and more substantial tape, like 2" clear packaging tape, is a better choice and multiple layers and overlap on to the glass and metal. If the condition is bilateral, fixing only one side can only cut the noise in half and most people can not distinguish a reduction of that degree. Masking tape and duct tape are risky because of residue. I don't think your dealer will give you any help with the trim defect

Thanks for all the info, i'll go to the dealer and order new trims.
I have removed the tape, and there was no residue.
I love this car, it's much, much better than my old GS 450h.
And a bonus picture of my "old" GS and "new" LS at the dealer

Great looking car - you really made a step up.
You might get very good results by just replacing the trim with new parts. The condition that causes the trim seal to fail is a fault with the car and not the trim. The concern with replacing the trim pieces with new parts is that the repair will not be durable – it may fail in a few days or weeks or months – and on some of the cars that is inevitable. It may be on your car that just replacing the parts will work just fine. The cost of replacement parts is about $15 per side and readily available from Lexus and Toyota dealers, so that seems worth trying, even with the possibility that you may have to do something like the DIY metal plate later.

I am sure that you will get lots of tire suggestions here.
I think a good choice is any of the "Grand Touring Tires" as they are all quiet tires: http://tires.tirerack.com/tires/Best...Touring%20Tire
Here is a link to a post, #130, from several years ago, about sorting out noise sources, that might be helpful.

Higgie, Jmcraney is too modest to tell you that he "pioneered" the solution to the trim piece wind noise. If that is your issue, it's not as simple as buying a new part. Take the time to read the link he provided you in his earlier post, then decide if you still want to just buy new parts.

I specifically wanted quiet tires for my 460L and settled on the Pimacy MXM4s. Not too many complaints other than they are beginning to show signs of cupping after about 20k miles. However, from what I understand most high-end tires will usually last a relatively short amount of time (less than 40k miles), and this car is not easy on the tires.

I have a '10 460L and purchase a set of Michelin's Pilot HX MXM4s. These tires are extremely quiet and smooth.

Michelan makes a great tire.
I've had great luck with the Pirelli PZero's on my Lexus, very smooth and have held up well over 25k miles on them so far. I think Benz uses Pirelli P Zero's as their OEM tire, at least that's what the tire guy told me. Also they were $100 less a tire than Michelans, which were stupid expensive for my application.
