Correcting the speedo with vcds is an interesting point. I would be tempted to go to 205/45 on the factory 17s if I knew I could keep the speedo legal. Look at that lovely sidewall and the kerb deflecting bulge. Phwoar !

PS great tyres. I've got very similar hankooks on my Tiguan and they're grippy and quiet and pliant.

Thanks tsi17,
If you are in possession of VCDS it is easy to do.
I did lots of testing under different speeds and this is my result.
Under 17-instruments / coding - 07 / long coding helper / Bit 03
Original setting is 01, on 03 setting speed mach with GPS but for my preference i change to 04 as this gave me more/less same speed tolerance as stock ( underspeed for - 2 miles )

I've been lurking around the multiple tyre threads for some time. The time is nearly here for me to renew the current tyres with something more comfortable, but not spoiling the handling. I'm potentially looking to replace-
OEM 195/40/R17 Side wall height 78mm
With
PS4 195/45/R17 Side wall height 88mm

As yet I've not seen this done (hence the new thread). To put this into perspective the side wall height on a golf with 18" wheels 90mm, so this isn't so crazy and shouldn't throw the speedo out too much (+2mph @ 70mph). I had considered slightly wider tyres (205/40/R17) on the fronts, but I'm leaning towards keeping them all the same. The PS4 is widely viewed as a comfortable tyre. People have gone with higher profile tires and not had any rubbing, so this shouldn't be a showstopper.

Anyone done this before with this size or tried staggered tyres sizes?

Hi All,
Just replaced stock good year tyre with hankook ventus s1 evo 3 205/45/r17
Ride quality has been improved dramatically, road noise, potholes and speed bumps are more settled.
Only for my observation the new tyre compared with stock did lose steering direction for a bit (feedback from tyre) but nothing major.
Yes, new tyre is bit bigger and speedo was of for +4 miles but this is corrected with VCSD
I had a problem driving on wet with old tires as I felt like driving on ice, no grip at all and driving on motorway noise was horrendous in the cabin, all gone with hankook tyres.
