What tyre pressure?

[treeroy]

Basic question I know but I'm googling what the tyre pressure should be and getting conflicting statements.

What is the tyre pressure stated from Toyota? I can't see pressure info written on the doors or anywhere.

I have 15" wheels all around, prefacelift.

edit: Sorry I have posted in the wrong section.

Have a look in the bottom of the glove box. Might find the sticker there.

26psi front. 32 rear.

26psi front. 32 rear.

As Jase says. However, many running the Toyo T1R's as you are tend to run them a couple of psi up from that to compensate/mitigate for the soft side walls. Others like myself took them right back off after 200 miles, sold them on at a loss & replaced with something that didn't squirm on entry to every corner.

My 2 is running 17" should I go up in pressure  - say 34 for rear ?

[Ardent]

Like above. Probably depends on what tyres you have on.

Given you are on non stock rims. The stock pressures might be of no relevance.

What tyres do you have on?

17" oh dear

[Joesson]

if I remember correctly  @StuC has 17" wheels, maybe he'll notice this and post up the pressures he uses.

Use stock pressure as a guideline.
Running 17" Pirelli P7 at 29/29 works for me

Use the converter as guideline. Ever going to 195 up front or a higher pr means that the pressure needs be adjusted to compensate for the change to keep OEM value.

"the converter "?
Roadstone n8000 Rear: 215/40  Front:205/40 - which will need replacing soon-ish

New one to me good idea too.
Not that I need it even with 250 ftlb at the wheels I'm on stock pfl sizes.

Thanks for that Petrus.
I'll get on it - (once I've fixed my injector leak! )

This calculator tells me that from original 16in FL rear wheels that I replaced with 195/50 15ins I should have gone from 32 to 41 PSI. I have Toyo R1R's and they're on 25 PSI on the rear right now so take this converter as just a general guessing point but even then, probably not as reliable as I'd like it to be.

Why would you have 25psi in a FL rear tyre? Or am I just misunderstanding.
I know r1r is a serious track tyre and I'd imagine would have very stiff sidewalls but surely that's too low. Or is it for the track when the tyres get really hot?

I wasn't that clear in my post anyway, I replaced the rear wheels on my FL with OEM set of front 15x6 inch alloys, so it's sort of PFL set up but even more square.

I wouldn't go less than semi-slicks on these cars anyway but I don't think I will manage to go to tracks this year so I should technically be going above 25PSI but I don't want to wear out the middle of the tyre prematurely as it produces a "ball effect" with higher pressures. On track these should perform best at 27/30 hot.

The sidewalls are less stiff than NS-20's on 34PSI according to my butt dyno, actually a rather comfy ride. I still get 38-40mpg mostly city with 22 front and 25 rear which I can't wrap my head around.

I use 34 for my rear pressure on 17". 👍

Only use 28 in the front.

[Topdownman]

I just thought I would try my tyre sizes in that calculator.

I compared 185/55R15 82 to 195/50R15 82 and that remained at 26psi.

The rears though were different.

I compared 215/45R16 82 to 225/45R16 82 and the 32psi dropped to 29psi recommendation.

Something to think about!
