Hey guys, Just picked up a low mileage 2018 Bentayga. Absolutely love it! Question about the tire pressure:

The door tag says should be 43 psi front and 50 psi rear. But the TPM screen says it should be 45 psi front and 53 psi rear. Then the TPM screen also suggests only 35 psi all around if partial loaded -- which in my case it will always be since I always drive alone and with nothing in the trunk. And then the Bentley dealership says they fill ever Bentayga up to 34 psi all the way around. So which is it? There's literally 4 different recommended PSI settings here. I'm leaning towards the 35 psi all around because that's what the screen suggests for part load. For whatever it's worth, I had Michelin Pilot Sport 4 SUV tires installed, so I'm running summer performance tires and not all seasons, but the TPM screen doesn't even have an option for 20" summer tires, only all season.

Thanks in advance for your help with this tire pressure mystery!

 

I'd go with 35 just in case you exceed 143 MPH on the freeway.
Seriously, 34 or 35 will give a comfortable ride. The 43/50 will give you more "road feel" than you'd like.

 

Think I agree! I aired the tires down to 40 hot today and when I checked them, they were 55 psi! Took like 2 minutes each tire of just letting air out to get it down 15 psi! The dealer definitely overfilled them. I think I'll probably go with 35 or 36 psi cold, unless anyone has another suggestion. Do I have any plans to exceed 143mph, no, but I sure wouldn't want to have to worry about a problem if I did.

 

At over 143mph tire pressure would be less of an issue than flashing blue lights in the rearview mirror.

 

That's only if you get caught, Bruce! And only if you let off the accelerator!
