Yes of course, depends on roads and tyres, what I was told is 17; are quiter then 19; and if I get the 19; I should not tel much diff and I was just wondering if anyone uses 19; and do they think there is a lot of road noise

I'm obsessive about road noise, have swapped wheels and tyres on countless cars and added various forms of sound deadening over the years.

The Mk2 Tiguan is better than average in its class for road noise. It is almost silent on smooth tarmac. Like all cars, it allows through some noise on coarser road surfaces. Most of this is structure- rather than air-borne i.e. it is resonance in the tyre carcass generated by movement over the uneven road surface, then transmitted through the suspension into the bodyshell and then resonating into the interior of the cabin from the bodyshell and attached trim. This is a problem with all modern cars but the Tiguan is better than most.

19s will be slightly noisier than 17s because they are wider (235 vs 215mm), as well as being slightly stiffer due to less sidewall. But the difference is minor. Make of tyre will probably make as much difference. Proper tracking adjustment always helps too, as will keeping the tyre pressures at the "comfort" setting (32 psi all round on mine) rather than anything higher.

Maybe half of all Tiguans are on 19s and most of them seem to be shod with Hankook Ventus tyres. These are much better than the brand name might lead you to believe. I swapped down from 19s with Hankooks to 17s with Michelin Primacy 3's and the reduction in tyre noise was only very slight.

What road noise there is tends to come most from the rear wheel arches and into the boot area. Like virtually all hatchback style vehicles, it is quieter with a full boot.

Happy to help further :)

Best to check the noise data on the car tyres as they quote the dBa (noise) value, the greater the value the louder.
A rough guide is that 3 dBa is double the perceived level - I think your Golf may have been fitted with 69 dBa tyres but the Tigs are all on 71 dBa irrespective of rim.
Those ratings are for the external drive by noise. They're not a reliable indicator of noise coming into the cabin. For a given level of vibration energy put into the tyre, it may actually be better to have it bleed out as external noise rather than transmit into the rim/suspension/bodyshell/trim.

One more thought: your Golf Cabriolet probably didn't have much tyre noise resonating through the bodyshell because it was a cabriolet and just didn't have the same rigidity. Was it a Mk6 ? We had one of those and it was pretty quiet for road noise. The other thing is of course that, like other cabriolets, there is more wind noise around and over the top half of the car, which pushes any tyre noise further into the background.

Others have reported having a strange noise from the front of the car, I wonder if you have the same issues?

There is a couple of threads reporting noise.

I came from a Golf GTi on 18" wheels
My Tiguan is a lot quieter (but I do miss my Golf) :cry:

I drive over one section of raod and just about need ear defenders because of the high noise level.

I drive our Golf and I am always surprised how much quiter it is at any speed.
