Lexus would not sell a pre-production model. It sounds like your roads are similar to those in Australia, where we have a lot of coarse aggregate surfaces which generate various degrees of road noise, some really bad. I have had a Lexus IS200, a GS300 and now the CT200h and I think they are all similar. In fact, driving along a regular bad stretch, I think the CT is marginally quieter, perhaps because everything else is so quiet. They say the aggregate road surfaces are long-lasting and give superior grip, but they sure are noisy, and I am told that a lot of major tyre manufacturers are unfamiliar with these surfaces and so they don't make a tyre that could really help.Thanks! Well, it is quiet on a good surface, but the issue is that most of the national roads in Ireland have this coarse surface that makes it really noisy, much noisier than in my previous Mazda 3 on same road, which is not the most silent car itself. Anyway, I am thinking to try Continental tyres soon, I will share my impressions then.
I hope that my CT is not a pre-production one In general is there anything else, except chaging tyres can be done to reduce noise on a coarse road?
So the Goodyears are much quieter than the Yokohamas?i changed my Advan a460s to Goodyear Efficientgrip.
took a terrible hit on cost (my Advan still is very new, traded in for 100 bucks) goodyear costs 550 bucks per.
it much much better.
was wondering, would it be better to change tyres? or get it sound proofed?
