Hi guys.
Just thought I would get some correct information out there regarding the current hilux models (most of you should already know this).

Under normal vehicle operating (ie. not carrying a heavy load) the Toyota handbook recommends a tyre pressure (for both the 17" and 18" rims) of 29psi, front and back (that's 200kPa).

When your new car is delivered the tyres are usually pumped up to a staggering, back-breaking 50psi!
Save your back guys and let some air out.
Twenty nine.

Cheers,
Tone

The last three cars I have bought off Toyota have had over inflated tires. My current car came with 40 psi my last Prado came with 60 and so did the previous hilux. I have asked a few people why including tire fitters and car shipping people and both had plausible explanations. The tire fitters told me it's common practice to inflate that high to ensure correct seating of bead on rim. I was also told because they are parked so close on the boat it avoids any additional rocking of cars in rough seas. I'm not sure about the latter but the former makes more sense to me.

Yep, this is very true. When I got mine new, I thought the ride seemed a bit harsh but chalked it up as to having an empty tray. Checked pressure next time I was at the servo and they'd cranked it up to 46-47 on every wheel. Bit much!

I run 36 psi hot about 32 cold...

I may be able to add to the info above as I work on the last remaining fully automated tyre fitment production line in the country.

The high pressure is for the first reason above. We pump to 50psi in about 1 second (around the bead, not through the valve). This is to seat the tyre correctly on the rim.
The assembly then remains at that pressure through vehicle assembly, shipping, transport etc.
I've also been told from 2 different sources, that the high pressures are not reduced by the car manufacturer because it helps prevent flat spots forming on cars that sit around for too long.

Poor dealer pre-delivery is why some of you are driving on tyres as hard as rocks.

Good tip. I checked mine last night and they were at 40psi. My Hilux is now 14 months old and I've never checked them. No wonder it's so harsh!

Yep, that's your $1,575 deal pre delivery charge at work, they don't even check the tyre pressures....

LOL, 14 months !

6600km on the clock also!

Good on ya for being honest but get prepared for the "give your self an upper cut" comments

40psi u feel every ripple in the road, once they heat up probably go to 44?? That is why I am running 32, much more comfortable.


Hutch- 2016 SR5 D4D Auto.....in Red as they go faster...

I agree, I run 32 psi also. 29 seems just a tad too low for cornering etc.

I just checked mine 35psi in all 4 tyres
I lowered them to 30psi... I don't carry any loads and the hot weather and roads up here in the NT the tyres probably heat up 20psi when hot.

Be gentle coz this is only my second post after introduction.
Must have got my money's worth for my pre delivery. Tyre pressure set at 30 psi.
Looking for recommendations about pressures.
How far would you drive on a sealed road after airing down for beach driving.
I like the idea (read lazy) of deflating to 18psi at home (5kms from beach)
After beach driving, drive home, 5 kms again, and re inflating with compressor in shed rather than the small compressor I carry in the car

thanks

So long as you go slow, especially around corners.

6600km / 14 months

Every 4x4 owner should own a quality pressure gauge. I have a Hafner gauge, $29 delivered (Ebay).

I finally took my Hilux for a spin today after dropping tyre pressures to 30psi. What a difference! It feels like I'm driving a cloud vs driving a brick.

Great to hear. It does make a difference, I felt it straight away as well.
Magic carpet ride

Yep 30-32 seem like the magic number....

2014 SR5 on standard rims and tyres. Ran 40PSI after doing advanced driver training (yep in the Lux) and at 32 the tyres really squealed but at 40 it handled better. Problem was car unladen the kids bounced around the back seat (they thought it was great but the boss felt it was too rough). Put BFKO2's on and ran 40 and still really bouncy so dropped to 32 unladen. Still bounces but much better than 40.

PS. Anyone thinking of new tyres- the BF AT KO2's after 12,000 kms are quieter than the standard HT's and they grip so well sometimes the car is dangerous as you go to take off in the wet the ute takes a sec to take off now as the tyres grip that well. Only driven on unsealed gravel and some sand and very happy with them.
