Calling all 4.5 Facelift owners with the 19" elias wheels. What tyre pressures are you running? Paper inside fuel cap says 2.7 bar all round, which is 39psi. Seems high? Car was delivered with 34psi. These have dropped slightly due to cold weather and now wondering whether to keep to 34 or crank up to 39?!

Go with what suits your use, comfort and safety, grip / traction rather than fuel use reduction. You know how the car is loaded or not and driven, and where. You can adjust the pressures to suit the weather. Summer in the UK is 2 seasons away.

I understand that, I’m just wondering what others are running?

This is still relevant to the 4.5: https://www.briskoda.net/forums/topic/527588-recommended-tyre-pressures-are-they-too-high/

I’m running 39. My last car had 225/45 18s and I ran 37-38. I have tried a few psi less and it just seemed to have more movement. I don’t find the ride bad at 39 although I have DCC. My oem tyres are Goodyear Eagle F1 Supersports.

Most people underinflate their tyres which leads to less grip, less fuel efficiency and more wear.

Cool. My car came with Bridgestones which I’m not a fan of. Look forward to swapping them out to Michelins when the time comes.

Topped up to 39 psi earlier. Noticeable difference in a good way.

Yes I don’t like Bridgestones much either and most cars here (NZ) have them so in guess I’m lucky. Didn’t know much about the Goodyears but they are up there with PS4s and feel like that too. Although I’ll probably switch to Michelins anyway they are my preferred brand for 2 and 4 wheels.

Bridgestone's in general I've found to be rather noisy (the more sporty orientated ones, not the eco type), not bad for wear/grip but that tyre noise is a turn off.

I found the Good Year F1's were fine, but wore rather quickly. I replaced them with Toyo Proxes Sport's - I've always had a good run out of Toyo's on previous cars, seem to wear well good grip in wet and dry and last well too. Not to mention there's often some good deals on them!

NZ tends to be a little unique for tyre wear due to the coarse volcanic chip that predominates on our roads.

Nothing wrong with Michelin either to be fair - just put a set of the new Power 6's on one of my bikes, definitely prefer them to the Pirelli Rosso III's I was running previously.
