Yeah the Re50s are friggin loud when braking. I have 4K miles.

My old 350 with Dunlops were quiet... however, IMO, the Bridgestones are a much better performing tire(or else the 07 IS is just better than the 06). Steering is more tight and predictable.

Its also better in the wet. So, I will take the noise and the bridgestone over the dunlops.

Well,

Lexus, said they are not going to do anything about it. The dealer said no, and Lexus customer care said no... I made my case that even though tires are not technically covered under the warranty, I didn't get a choice of tires on the car when I bought it and that I bought the tires/car as one package from Lexus, so why shouldn't they cover it.

It's amazing to me that I have to turn the rasio to a volume of 20 to cover the tire noise. yet my 16yr old galant doesn't have this noise.

You guys think I should contact Bridgestone? Tire rack racks the re050 as having a 7.x noise level... and they rate the re050 A pole position as having a 8.6 noise rating... should I upgrade to the re050 A pole position? Hell, maybe I can get Bridgestone to pay for some of it.

You have max performance summer tires on your car with a 40 aspect ratio. Your galant probably has some touring/all season tires with something like a 60 aspect ratio. You're comparing apples with oranges.

There are compromises with any tire. If you drop down to a 16" wheel with a 60% aspect ratio and put on a touring tire, I'm sure your IS will probably be quieter than your galant.

Unfortunately, your 45k luxury/sports car is equipped with ultra high performance 18" 40 series tires. Of course they won't be quiet. You can't blame Lexus and you can't blame Bridgestone. Believe me, if Bridgestone could build a quiet ultra high performance 40 series tire, they would. The noise is the price you pay for having such high performance tires on your car. It's an unfortunate drawback and not specifically engineered into the tire. Lobux is right, they will get louder as the miles build. Ride in ANY car with 18" 40's and you'll understand. It's not just Lexus.

Its a sound insulation issue. If you strip the car you might be surprised how little of it there is. Also note that tire noise is much louder on the drivers side than passenger side. Also the new foam based melt sheets are perhaps not as effective as the asphalt ones.

Hello.

I am no doubt new to the board. I have had 4 Lexus cars in the past and was looking for another.

I test drove an IS 350 with the 18" sport tires and 9000 miles. All was well till I turned the stereo down. Whirrwhirrwhirrwhirrwhirrrrrrrr.......

I asked the dealer and he said this was a "quiet one". WOW

I have been this route before. Had a Range Rover do the same thing. Rover would not cover it and the Good Year would not cover it. RR pointed at Goodyear and Goodyear pointed at an intrinsic problem with the vehicle.

It was a nightmare. 2 sets of tires and a lot of out of pocket expense finally solved the problem with a set of Hankook tires but that is a lot of time and money to go through for a quiet ride in a "luxury" vehicle.

I have another sport sedan with 20" wheels and 25 series on the front and have absolutely no noise.

Perhaps it is a car + tire combination issue.

We really really really liked the IS but are not ready to deal with any expensive tire swapping issues.

I have searched the forum. Does anyone have a time-proven solution?


Thank you.

Which tires are these?

It's a problem for all of us second-gen IS owners. We all have it. And those who say they don't either aren't listening very carefully, or they're coming from a car that considerably more road noise. There's nothing you can do about it, aside from trying to sound-deaden your car, or buy quieter tires. Our cars have sport tires, and they're naturally going to produce a lot of road noise.

I know that sport tires are a bit loud but perhaps there is a brand that is not so noisy. The dealer recommended Michelins...

This is a common issue with a lot of factory spec tires from all manufactures. Bridgestone does make quieter sport tires. Tirerack is a good place to compare several models and what actual users have to say. You'll notice that many have commented about the tire noise, with the same tire, on a lot of different cars. It's the tire, period. But there are many other choices available. I hate it too. So when I replace these, my next performance tires will be rated higher in the quiet factor for sure.

Goodyear F1 A/S are pretty noisy too.

If Lexus had made this car with all season tires, crappy brakes, and a smaller engine, everyone would have complained incessantly. Instead, they put sticky summer performance tires on it, fantastic brakes, and 306 hp...and people whine about tire noise, brake dust, and the cost of gas.

Please don't call Lexus with these complaints, or you're going to contribute to the dumbing down of a great car.

Bridgestone RE050A PP are much quieter than the OEM RE050. Both are vastly quieter than my Supra on 265/40/17 and 235/45/17 - and I really mean VASTLY quieter.

It is a sport oriented sedan. Road noise is impossible to avoid if you want any kind of feeling in the steering and responsiveness when you steer. If you don't like the IS, you really should consider the GS or LS. They are far more luxury focused than the IS.
