Tyre Pressure 275/40/20

[9 Foot Shark]

Hi I am wondering what tyre pressures should be used for my T32
I usually travel unladen and runs 275/40/20 wheels

Any ideas as the stock tyre pressure doesn’t apply as I’m larger than the Devonports

40 psi front/rear in my T32 on B14's and 20's

Trying to figure out best tyre pressure on my T6 - I'm running 275/40/20 tyres, internet searches are bringing up anything from 36 to 48 . . .
Thank you all!

36-38 should be fine depending on load you’re carrying. 48 is way too high!

Thanks Chris, I've put 38 in and feels fine, just started second guessing myself!!

I only clicked on this thread to see someone running 275/60/20 profile tyres on a T6 as per your thread title.

I'm left disappointed

That’s exactly the same reason that I clicked on it!

What's the ideal pressure for 275/40 20" tyres

 

[BognorMotors]

On a 265/40 and 275/35 we recommend between 36-40

Personally I've found the sweet spot a 36, increasing to 40 if a full load.

36 seems to give the perfect setup, with even tyre wear.

Hi, I’m struggling to understand my tyre pressures to be honest. This is my tyre… cannot figure out what size / pressure it should be at all. Even took to the local garage and the guys just said 46 all round? They look low but have always looked a little low… not sure at all what PSI I should be running at as the door sticker doesn’t relate to anything on the tyre. Can anyone help? I’ve inflated to 45F and 40R but I’m worried that this is too high for the type of tyre. Off on a long drive this week thanks in advance!

Your last pic is the tyre size;
275/40 ZR20.
The ZR says it has a speed rating of over 149mph and the W confirms that as 168mph... if you're even remotely close to that I want to talk to your engine tuner.

I think this is a relatively common tyre size for 20" wheels, I suggest you check out what Oli at Bognor Motors has to say on the subject...

I have these tyres as well on my T6, T28, so much variations in suggested tyre pressure. Mine has a standard kitchen layout and usually just me, and some luggage, so am I right in thinking around 46psi front and back?

Thanks - do you have a link to Oli at Bognor Motors (on here or webpage?) I've gone with 40R & 45F for now but do want to know if that's too high.

Me too - luggage and usually me, on occasion an other. The guy at my local garage said 46psi front & back but what I've read on here makes me wonder??

I know, the more I read the more unsure I am

It's worth remembering that manufactures recommend higher pressures to save a gram or two of emissions, so generally lower pressures are more suitable.

2.6bar all round is not a bad starting point.
