Hi newbie here .im somewhat confused as to the correct tyre pressures on my 2019 a5 petrol sportsback. On the door decal it shows what shd be with usual load 39psi fronts and 36psi rears but dont feel right...ive heard of oeners puting on 32 all round or 36 all round...any a5 b9 owners here let me know what works best....my tyres are  stock ...Bridgestone potenza s001 255 35 R19 ...thanks!

Hello Bob,

Welcome to the forum. 

My view is...why would you want to deviate from the pressures recommended by VAG following their testing and trials in conjunction with their tyre suppliers? 

You mention ‘...don’t feel right..’. By that, do you mean the vehicle doesn’t handle properly? If so, return to your dealer and seek advice there. 

Perhaps a little OTT, but consider a situation where you deviate from the manufacturer’s recommended pressures, and you are involved in an accident. Would you want to be in a debating situation with your insurers? 

All the above is just a personal view Bob, but why fiddle...? 

Kind regards,

Gareth. 

Hi Gareth

I understand and i know that manufacturers play around with tyre pressures to meet the lowest emmisions tests (along with other factors).the tyre pressures are usually exaggerated on data.it will be interesting to see what others put in their tyres.
