Tyre Pressure?

[BigMo82]

I hope everyone has had a good festive period and had some time off.

I was trying to find out what PSI I should put in my Avensis wheels. The tyres are 215/45/R17. I'm sure I read somewhere in the manual that they should be 42psi which seems way to high or am I wrong?

Low profile soaks up alot more road vibration though, anything over 46 psi is probably to much.

So 42 psi sounds about right...

[Heidfirst]

would have thought ~35psi but varies with load.

There should be a plate/sticker in the door frame with the info on it.

Yes there should be a plate/sticker on the base of the B pillar in the driver's door opening. Couple of websites I've checked this morning, both give the pressures as 34psi all round. See http://www.tyrepressurechecker.com/tyres/toyota/

As a general rule of thumb and this has always served me well.when i was in the tyre trade.Go by the size of the wheel.ie in this case 17inch then double it ..34 which gives you a MINIMUM psi,and then vary it accordingly on the weight you regularly carry,so lets say that you carry 2 passengers in the back and one up front increase the psi by 2 ort 3 psi,you wont go far wrong here.

35 psi all round. Higher pressures are 'advised' in the manual for continual high speed/high load work. 35 is the one to go for. Too high a pressure can slightly deform the tyre and reduce your contact patch hence reducing grip - not a good thing at this time of year.

Thanks for the replies, I usually go between 32-34 but was reading through the manual last night and was quite shocked by the figures in there.

Ok, I admit it: I had a panic and went to get the manual from the car. Panic over. It is 35 psi all round on yours and 42 (or 45/48 fully loaded) for speeds in excess of 100mph.

So, 35 psi. Which is nice.

(It was spotting that you are on 17 inch rims that got me flapping)

Lol, thanks for checking Druid Boy. I upped them all from 32 to 35 this morning.
