Sound Insulation

[UKPulse]

If I have one criticism of the IS200/300 (ok then, apart from corroding alloys & thin paint ;) ) it's that tyre/road noise can become quite intrusive. :duh:

Is it possible, or even practical to add any additional sound-proofing to the car?? If so, what materials can you use, and where abouts on the car?

...or is it just a case of turning the stereo up a bit?

You might wanna think about changing your tyres mate

I have Potenza S03 tyres fitted - very quiet

i dnt mind the sound but then i dnt drive unless i got cd player on.

Si (simon skippy) has had a crazy diamond audio install (lucky bloke) and has had it sound proofed. think he had something like 9rolls of dynamat and 3 rolls of brown bread all through the car. well that sort of bass and u need it

Road noise whats that

if i were you ,and i know it's an obvious one

but check your tyres and pressures

I know exactly what you mean about the road noise, I had this on my GS300SE and just put it down to the engine being so smooth and silent that the road noise was more apparant. Until I had 4 new SO3 tyres fitted recently and couldn't believe the difference, it's almost completely silent now.

Out of interest Rod, what pressures you got yours set to?

From memory - 32psi all round - I just go by the sticker on the door pillar mate - set it to normal speeds, low weight

set it to normal speeds, low weight

Diet paid off then!

Thanks for the info, I have mine set to around 34psi all round, just wondered what others were setting theirs to for best performance and road noise.

Tread & pressures are all ok, but I'm still running the standard fit Potenza "RE040"s(??) that came with the car.... gawd, I must be driving like an old woman - that's 21K miles!

Pick up the new '300 tomorrow, & I guess it'll come with the same tyres. But it sounds like changing them to Potenza "S03"s might be a wise move asap. Now what's this about brown bread? (Is that the stuff that looks like the old fashioned carpet underlay??) :D
