hello i purchased a set of kokomha tyres and told to run them at36lbs this seems high compared with mitsbushi recomend pressure any feed back would be helpfull thanks warrenlol

im pretty sure they meant 36psi which is about right.

high pressure is good, safer, more economical, better at speed

36 psi would be about right. What you have to remember is mitsubishi have that recommendation for the stock wheel and tyre combo only, if you have different wheels or even just different rubber, this can alter the recommendation, you need to follow the recommendation that comes with the tyre.

not always,

over inflation can lead to blowouts ( not good at speed ) and balloning which causes less surface contact with the road.

Put 40 in them.

Tyre pressure is a tricky subject,

Yes you should follow the recomendations stamped on the tyre,
but mine say DONT EXCEED 60psi, that certainly doesnt mean im going to go putting 59Psi in them.

In MotorRacing, pit crews make changes small as 1psi to suit the certain road surface on which they're driving ( The Track ), Because of the nature of roads, potholes, corrigation, sand, water, oil, different road aggregates. We cant be as specific. And dont need to be.

You dont measure your trip to work like this. 29minutes 28.192seconds. You would just say Half an Hour.

Anything between 34-40 for a "Normal" tyre is fine.

34-36 Is good for around town as there are lots of bumps and crap on the roads, and the lower the psi the less jittery the ride quality is.

However if your going on a long distance road trip, generally country roads and motorways are smoother. So increasing your Pressure to 40Psi will be beneficial as there should be less tyre noise and also less rolling resistance leading to better fuel economy.

Blowouts are not caused by overinflation unless you take it beyond the max for the tyres.
Blowouts happen when you underinflate the tyres and then go on a long drive, especially
in summer where the tyres heat up a lot (due to the steel belts flexing too much) and the
road surface temperature which increases the tyre pressure to beyond the max.

I agree with vlad on this one.Why would you anyway want to over inflate your expensive tyres and shorten their life by x amount of KM plus reducing contact patch which results in poor handling , both dry and wet, prolonged braking distance, lower cornering speed, comfort etc...
Avoid checking tyre pressure on petrol stations.Firstly because manometres there are inaccurate and you want find two that will give you same reading. Secondly always check tyre pressure when tyres are cold. If you , for instance adjust pressure to 35 psi on petrol station when tyres are warm you will actually end up with under inflated tyres. When tyre cool down pressure will be less then 35 psi, I would not know by how much psi, there are many variables like accuracy of manometer and temperature of the tyre.
Invest $20-30 in digital tyre pressure manometer, and $40-50 in foot pump. Don't buy cheapest one and there is no need to spend fortune on proffesiona equipment. Keep it in the garage, it will outlast several tyre sets. Measure pressure every fortnight or so always in the morrning. If parked in the carport always check pressure before sun gets on tyres. Pressure on the sunny side of the car will be higher than in the shady side.

im pretty sure my tyre placard says 26 but i run at around 40
depending on wether and whare im going what im doing tire pressuse is my main thing i check more often than oil

Tyre placards pressure settings are specified low for comfort reasons, not for longevity and
it is for OEM tyres.

Well I'm running on 41psi. On 16" rims, tyres Dunlops sp200e. A bit hard but good grip and economy. Well thats what I think anyways.
