Tyre pressures

I have recently bought a Hi Ace camper van. Went to check tyre pressures, and the manual states 47psi in the front, I'm OK with that, but the rears are specified as 65 psi. Maybe this is for a fully laden vehicle, but seems a bit high for a camper van. There is no loaded and unloaded info.

Any insights?

Thanks

Herb

Yes they are LT tyres.

Consider the weight distribution of a camper van, nearly empty at the back, with the weight of the engine, passengers at the front and very little at the back.  I would expect that the rears would not need 65 psi, as there will never be a 1/2 - 1 ton load in there. As is my compressor was struggling to get to 60 psi, a small diaphragm type.

I know about under inflation, and about over inflation.

Totally understand where you are coming from, In my little workmate I run 42psi front and 36-37psi rear ( unladen ) Tyres last nearly 90,00km and wear beautiful. They rely on pressure to support the stiff sidewall

      Buying 3rd hand 2010 Aurion Sportvio for $9000

      That is about the standard price you'd expect nothing crazy, I paid pretty much the same for a 2008 model with 160k on the clock. As to the high km's and maintenance, 165,000km for a Toyota is nothing to sweat about and the maintenance/repairs are pretty cheap. If it's been treated well by the previous owners and you continue to look after it then it will easily last you another 5 years.

      Removing low beam bulb 2014 Camry

      I apologise if this is an idiotic question--I've searched and watched dozens of videos on how to replace a burnt out bulb, and i'm fine with it (i've even done it before, though it was years ago). the problem is that I can't seem to get the bulb out of the 'plug'/base--it seems that that is too blindingly obvious to be explained or shown on camera. I can't remember what I did last time I replaced a bulb... I don't know if I have to push something on the fitting to release it, if i have to twist it, or just yank really hard. I've applied as much strength as I dared, but am afraid of breaking something if i try to brute force it out. I could just pay $15 for someone at supercheap to pop it out and replace it for me but it's become a matter of principle at this point... I'm unwilling to admit defeat. The photos below are from a different post on this forum, but they're the same exact kind of bulb/fitting i'm struggling with... Any tips would be much appreciated. My wife is getting really annoyed with me because we can't drive at night but i'm too stubborn to pay $15. Thanks!

      Aftermarket Air Intake

      Hey all, Just recently bought a 2007 TRD Aurion and am trying to find an aftermarket Air Intake, but am coming to the realisation that there is a very limited market for TRD Aurions. So far the only system I've been able to find is a K&N Typhoon Intake (link here: https://www.carmodsaustralia.com.au/KN-Filters-69-8611TS-69-Series-Typhoon-Performance-Air-Intake-System-Camry-35L-07-11?cq_src=google_ads&cq_cmp=18898892770&cq_con=&cq_term=&cq_med=pla&cq_plac=&cq_net=x&cq_plt=gp&gad_source=1&gclid=Cj0KCQjwpZWzBhC0ARIsACvjWRP893VLnAQsxIZJjcW5Go75b_T2N25rSWBVu6IeDziM2v41bpeyOREaAg1fEALw_wcB), however when viewing specifications for the product it states it fits Camry's from 2007-2011. Further digging revealed this product is an import from the USA hence why it's for a Camry - they don't have Aurions there. I am aware that they both share the 2GR-FE engine so I'm assuming the product will be able to be retrofitted to my TRD, provided the throttle body intake is the same diameter across Supercharged 2GR-FE's and N/A 2GR-FE's. Has anyone else in Aus had any luck sourcing/fitting one of these K&N Intakes, or know of another brand that do them specifically for the TRD Aurion's. Pretty confident in just ordering the aforementioned kit but their return policy sucks (can't return and refund if packaging has been opened, etc). Cheers guys! Jason.

      Heater problems

      My Toyota Celica SX blows cold air at the driver’s side when the heater is on, and it is an absolute nuisance. I get that it takes a while for the heater to work properly, but some reason after I have the heater on, it starts blowing out cold air even after a good warm up! I feel like the heater core may need replacing or the air conditioner/heater needs re-gassing.

      Entertainment Unit Upgrade

      Hi everyone. Just after some advice on head unit upgrade. I'm looking to upgrade the functionality of the entertainment system to do a few things - display my dual camera from my caravan, utilise the HEMA OnRoad/OffRoad module, stream to the rear screens, and include wireless apple play. I've narrowed down to the most popular which seems to be Advanced Ice, EC Offroad and Galios - but none seem to do all four functions seamlessly. Not sure if I'm actually looking for a unicorn or not...has anyone had any experience in installing one of these systems and has it done all the functions? Any regrets? Cheers Mark
