Correct Tyre Pressure

[Mr-Lex]

Sorry people bit of a silly question...what is the correct tyre pressure for IS200? Can't find my manual...and who else I thought of...? :D

[Zee007]

Isn't it about 32psi ish..........

[NigeSt]

I wouldn't be surprised if the tyre pressures are on a sticker somewhere around the inside of the driver's door (on the body shell). I'm not near my own car to check, but that's pretty common practice.

Tyre pressures can be found on a decal inside the drivers door. Open the door and look on the foremost side of the centre pillar, voila!

Just had 2 tyres replaced and the bloke at the garage said it was 38 at the back and 36 at the front <_< Seemed a bit high to me but I just let him get on with it. I will check in the manual later.

There is a sticker on the inside of the drivers door.

That's roughly what i got told too, but the tyres looked n felt like i was driving 4x4 wheels off-roader..

So i reduced the pressure to 33 alway round, feels ok n looks ok too.. (Don't understand the panel on the door - too many numbers )

38!!!!!!!!!! far too high!!!! the decal is easy to understand - lots of numbers because it includes 16" tyres also. heavy load, normal load and different speeds.

as a rule for general everyday driving the pressure is 33PSI front and back.

33 sounds right to me. That's what they were before.

38 does feel like I'm driving a 4X4, :P will be reducing the pressure back down to 33PSI front and back.

[LennyLexus]

Right, from what I can gather from the door sticker is 33psi all around?? But when I checked mine, they were set at 38 from the dealer!!

I rang Sanj, he said try 35.. coz its in the middle

Can someone please confirm what the best setting is? I have the bridgestone tyres fitted by the dealer as standard, and I have the standard 17"s.

[ColinBarber]

33 for general driving. Higher if you load the car or travel at speeds above 100mph

[LennyLexus]

are you going by the book, or your personnal experience Col?

Because I've very rarely heard of people sticking to the recommend.

But I got to be a bit more careful now, as these tyres a bit more dearer then my old primeras

[Bazza-old]

what about 18"

[LennyLexus]

what about 18"

Remember this?

I think that's the book figure but the car seems fine on that setting - I've no need to change. That is with SP9000s. Maybe the Bridgestones work better on another pressure.

On the GS I lower it slightly to get a better ride.

[LennyLexus]

Maybe the Bridgestones work better on another pressure.

Ah... Well the dealer did set to 38.. anyone with Bridgestones?

And when should I get them switched (fronts to backs & vice versa)

[Bazza-old]

manual states:

215/45zr17 type a

from 49 psi

to 33 psi

215/45zr17 type b

from 51 psi

to 33 psi

205/55r16

from 48 psi

to 33 psi

depending on speed and capacity of vehicle

and if towing add 2.8 psi

now thats confusing !!!!!

what a memory :)

If you rotate them then they will all wear evenly - expensive when you need to replace all 4

[LennyLexus]

surely its cheaper (price per tyre) to buy 4 tyres then 2?

And roughly after how many miles, should you rotate them?

[CruzMissile]

and what about tyre pressures in dry and wet conditions... does less pressure give more grip in wet road conditions?

I tend to check wear on the tyres also... If they're inflated a lot they'll wear out more in the middle of the tyre when driving at high speeds. So when I notice that I deflate them a bit to get them to wear out more on the outsides.

Hard inflated tyres also give more mileage...

Hard inflated tyres also give more mileage

and more mpg

O O,

that might explain, y i got lower mpg this weekend then

So its probably better to leave it at 38psi?

[ColinBarber]

Personally I think 38 is too high for this time of year. Too easy to lose the back end.

isnt that what T/C is for?

I have felt a scared taking onto the motorway in rain at certain times...

But i thought that was more to do with not having a RWD before

[CruzMissile]

T/C isn't boy wonder since it will allow in certain situations to keep in control without the back end sliding out.

If, however, you turn in hard on a wet road surface, T/C on, and your back does break out, you'll need all the steering skills you have to keep it from spinning 180° SINCE YOU WILL LOOSE ACCELERATOR CONTROL due to the fact that that's just what the T/C does : it cuts the juice! NOT GOOD, in certain situations.

I prefer to drive with T/C on when I'm cruising and will not engage in hard turning.

Though I prefer to have T/C off if I would want it to be "possible" for the car to break out controllably since then you can manage the sliding by accelerator.

All this is quite difficult & tricky if you first start driving rwd cars. It would be nice to look for an large empty lot on a wet day to start experimenting with the different effects of turning and drifting, using T/C and without T/C.

I have always driven rwd cars and if you're in it for the sport and enjoyment of driving and don't see your car merely as a means of transportation, then you might find rwd the only way! :winky:
