There will be many different opinions on this, and by far the most will say buy Michelins, but these are possibly the most expensive. My own preference is for Hankooks. Buying the tyres with the lowest db rating on the now compulsory tyre label should give you the quietest tyres. A reading of 68db is quiet, and you will find the level goes up to around 74db with some brands. 

I am testing some cheap tyres at the moment put on free of charge for me to asses over the next 10,000 miles. At the moment I can say they have exceeded my expectations in all aspects including noise level, but it would be unfair of me to disclose the brand until I have put at least 5000 miles on them. I am only at 500 miles at the moment. They are less than 1/3 of the price of so called top of the range tyres.

Tyres get noisy as they ware so your Dunlops are probably suffering from this. 

The tyre label gives information on wet grip fuel ecconomy, and noise level, so have a look at suggested tyres. The economy rating can make such a difference as to pay for the tyres in there life on fuel saving so do not ignore this rating, and the wet grip speaks for it's self on safety stopping distances.

Thanks for that John,,our tyre technician in work ( we have a big fleet) keeps banging on about anew tyre called Tigar,which are made by Michelin,trouble is,whatever I buy,they will be on it for a while so I have to do my homework.

Check the label/spec as John pointed out.





Dunlop Sportmaxx2's are one of the quietest rated boots I've seen. They're also fair all rounders.





Eagle F1 Assym2's were good but the latest 3rd version don't seem as popular.





Tyres are like Marmite tho and I'm interested to hear what other GS owners prefer.

Got a yokohama on my old is220d and it was really grippy and not that noisy. Got a gs was fitted with bridgestone and i would say that it is as good as the yokohama. Michellin i think is the best  but expensive. But Lexus cars is very quiet compared to other saloons. 

I know someone in london who can give you a very good price for premium tyres

I've got Michelin CrossClimates on my GS. I can't say they are any quieter than the ones that it came with, but the noise does not seem so harsh so it's easier to ignore. I think they've cut some of the higher frequency noise.

They only do XLs in the size I needed and there is more vibration coming through the steering wheel now, but I wouldn't say the ride is noticeably worse. I haven't tried them in the snow, but in cold wet weather they do corner with confidence and I haven't felt them lose grip or concern me in any way.

I think if I could have got non-XL tyres they would really suit the car, but there is a bit of a compromise with the vibration because they are XLs. You could say it helps you to feel more connected to the road though.

Are you up to 5000 miles on your tyres John?

I have now covered a little under 4,000 miles on the tyres. While it would still be unfair to give an accurate assessment on the ware rate "appears to be good" I can say the tyres are quiet, but not the quietest tyres I have used, grip well in both wet, and dry conditions, and give good steering response. This information is based on normal road use on mostly rural roads with no motorway use, but lots of spirited driving on the sort of roads enjoyed by "Big Rat, and company". I am not saying they are track day tyres, but good value normal motoring tyres. The tyres replaced a set of Yokohama's with around 5mm of tread, and compare favorably against these in all respects. 

 I am now prepared to name them even though I have not reached 5,000 miles, and this is where I expect to get shot down in flames. The tyres are made in China and are Three A brand P606 rated for M&S but not winter tyres.

Price expect to pay £55 around each fitted, and balanced for 245/40/18's. I am not in any way connected with the tyre company or it's sales just an honest opinion on the tyres I have tested at as yet limited millage. Any further developments good or bad will be posted here.

Does anyone have any further advice on choice of quiet 18" tyres for the GS300h?

The problem with the decibel rating published is that's OUTSIDE the car, not the noise in the cockpit.

I've got Dunlop SP Sports on at the moment, and the back ones are just weeks away from needing to be replaced.

I am still disappointed at how much road noise there is in the cabin. It's the one thing that the Lexus doesn't do as well as my old Merc E Class!

The noise inside the cockpit is entirely dependent on the noise insulation of the cockpit, and suspension bushing. The only way to measure the noise made by a tyre is from the outside as internal measurements would virtually meaningless. Every car would be different.

I read a test on Auto Express where they put microphones on the head rest when testing tyres.

I guess what you're saying, John, is that each vehicle will respond differently to a particular tyre?

It's a bit of a lottery I suppose!

That's about it. Also with a mike inside the car you are also measuring engine, transmission noise, and even wind noise. Road surfaces also have an enormous impact on noise levels that cannot be directed or attributed to the tyres.

I've just ordered 4 Goodyear Vector 4seasons Gen-2 tyres. I'll let you know what they are like soon.

Just to update,I did fit four new Michelin Cross Climates to my car,,not a massive difference in the quietness,but the handling and steering,Road feel is very noticeable,,and Iam very pleased with these tyres,time will tell on wear.

As you note, the external ratings have no relationship at all with how loud the tyres will be inside the car. Worse, I have heard that some tyre manufacturers are now allegedly gaming the measuring system by using tread patterns that direct sound into the wheelarches (thus increasing internal noise) to make them quieter in the drive-by test! There is simply no way of knowing whether a given tyre will prove to be quieter in a given car, without actually fitting them!

I share your view about the excessive road noise in the GS, although I suspect tinnitus makes me more sensitive than most as it doesn't seem to be a common complaint. I may take a punt on Yokohama BluEarth when I replace the Bridgestones, as I have no interest in handling (the Yokos are rubbish apparently) but some reviews suggest they are supposedly quiet and economical which are the two things that I am after. However, I'm not expecting a dramatic improvement either way.

I've got these on mine too. I agree that they are not noticeably quieter, but I think the sound is not as harsh as the original tyres and they can be virtually silent on right surface. I also agree that they handle really well in all conditions, very safe. The only issue I've found is a bit more vibration through the steering wheel, presumably because they are XL tyres. I've got used to that though.

I think they're very good tyres.
