I just got an 06 LS430, with 18in wheels. I wanted 17" wheels, but they were nowhere to be found. The noise level in the car is fine when travelling on clean roads, but it is higher than I like on concrete, bad pavements, etc
Of course rough roads are noisier than clean roads, but does anyone have any data on noise comparisons between 18in and 17in wheels + tires. I know a lot of it will have to do with the specific tire choice as well, but that also favors the 17" wheels since the 225 17 55 has a lot more choice for quieter tires.
Any data or pointers would be appreciated. Also, any specific comparison of specific tires on the 17 rim would be great.
Thanks.
