Hi there,

Does anyone know what the correct tyre pressures are? Mine is a 2002 Verada Ei Series 2. The owners manual has a circular reference (the page about tyres says to check another page, but that other page just refers back to the original page and neither contain tyre pressure details). I also thought maybe they would be listed on the tyres themselves but can't seem to find them...

Anyone know?

We are going on a big trip soon and just wanted to make sure everything was ready.

Thanks!

35Psi is what the sticker on the base of the "B" pillar says on my TL says for a full load. That's using factory tyres. I usually bump it up to 38psi when cruising at 110+ Roma to Charters Towers.

+1

Disregard the talk about LPG from this quote, But you get the Idea, If I was to do a trrip and I had 16-17" wheelz, Id run 38 cold in the front and 36 in the back....But 38 all round would do....Mind dirty gutters, kerbs and roadside debris when running high pressures, stay in the well worn area of the road, punctures can put a hole a the holiday budget.

Saw the Mythbusters Tyre pressure test.....
Search it.....

Results are in.
35 psi (control)
tyres at 10psi = 3.7% increase in consumption
tyres at 30psi = 1.2% increase in consumption
tyres at 40psi = 6.2% decrease in consumption
tyres at 60psi = 7.6% decrease in consumption.

However, they they did remark at 40 psi you are more likely to get a puncture. Which argues the point over a 40 psi tyre pressure.
I just avoid gutters and driving for the Apex Cornering.....Stick to the 40 PSI and stay on the well worn parts of the road, to avoid punctures.

They also left this out of their test, a cold tyre @ 38 PSI will be 40 psi at working temps. So 40 psi is actually 42 when they warm up.

As for 19 litres per 100, get another LPG workshop, that's total Baloney. 7-8 K's (12-14 l/100) per litre should be acheivable. Less if Phang it.

I'm averaging 14 l/100, and If I could be bothered I could get a lot less than that, but that's no fun...............

Good luck

BTW 19l/100 = 12 mpg. Thats really, really, really, really bad. 12 l/100 is about 20 mpg much better, and 10 l/100 (23-24mpg) on the freeway is excellent.

yeah 35-38 for under 18inch wheels and 38-40 for 18 or over.

My tyre placard says:

so if carrying the equivalent weight of more than 3 people and going over 140kph, the factory recommendation is 44psi

I just run 40psi because the steering feedback is much better due to less tyre roll from my 16" rims or what just feels like squirming from the 18"s. 38psi isn't too bad either.

I run 36psi in the front and 34psi in the rear, this is on a TJ Sports running the standard 215/60R16 tyres. Gives a good balance of handling and ride quality, you don't want to go too high otherwise you lose both.

I run 38 all round, 16" wheels.

38 is the sweet spot. Anything between 35 and 42 should be pretty right. Wouldn't stress too much over it. Just make sure it is over 30 because deflated tyres can affect fuel consumption

And over inflation causing incorrect/faster tyre wear.

I think the over inflation causing incorrect tyre wear is a historical thing and doesn't apply nearly as much with todays tyre construction methods. Modern tyres keep the tread surface flatter when over inflated.
Under inflated on the other hand had does have issues - because with an under inflated tyre having more distortion where the road contact is, when the car is moving, this constant distorting increases heat in the tyre rapidly, leading to premature wear and potentially tyre damage.

Also, when driving in the wet, low pressure tyres will have narrower water channels because the tread closes up. Over inflated tyres will cause slight widening of the tread channels, meaning more water can be dispersed.

Hence, under inflated tyres wear out faster and don't grip as well, while over inflated tyres just give a less comfortable ride.
People get passionate about tyres and buying the right ones, but their condition is just as important. Personally I go for grip over comfort.
I agree with Dreggzy though, except I'd say 36+ psi as a rule of thumb. :)

Why do people run lower psi on the rear? I run 42 rear, 36 front on ralliart rims, keeps the rear stiff and allows the front to big in a bit for better launches... Well that's the theory anyway.

Very true

Why do people run lower psi on the rear? I run 42 rear, 36 front on ralliart rims, keeps the rear stiff and allows the front to big in a bit for better launches... Well that's the theory anyway.

The normal reason is because of weight distribution - typically, FF cars are have about 60% of weight on the front, so the back can be a little lower air pressure. If it's a traditional FR (eg: falcadore) the idea is run the same all round and if it's RR (eg: 911) run higher PSI at the back.

However, if you prefer a little less at the front and a tighter rear end (who wouldn't) that's your choice too, especially as you've met my rule of thumb of 36psi minimum :)

Less weight in the back so you don't need as much pressure for the same contact patch on the road.
