Tire Pressure

I run whatever the tire manufacturer recommends and not what the door says. They can vary as much as 45psi.

 

this.
plus load can be a something to consider as well.
A fully loaded bed might need higher PSI (maybe even just in the rear) than an empty bed would.

 

Yeah, because 80 psi in a Tacoma makes sense. Because a Tacoma weighs as much as a 1 ton diesel truck.

 

Around 32/30psi cold. I never have to air-down for the beach & gives a smooth ride and a full contact patch.

 

Chalk test.

 

33 psi all over

 

36 Front / 34 Rear

 

Contact the tire manufacturer and provide them with the vehicle type and tire type and they will provide the recommended psi. Does 80psi make sense on a tacoma? No. Do Load E/F tires make sense as well? No, but people put them on.

But to correct your sarcasm, you don't put 80psi in in your tire based on vehicle weight, its based on load weight.

 

So you don't think Toyota and the tire manufacturer have worked together to create the recommended door sill pressure on stock tires?

 

Who said anything about stock tires? The OP didn't.

Additionally tire manufacturers are different and may have different recommendations.

The plate is Generic.

Using you 1-ton truck example(though I'll be using my F-250), the plate recommends 45 psi. Michelin recommended 65 psi...

 

.. and sometimes it's spot on. I called up Michelin customer service to double check their recommended tire pressure for my wife's Rav4. Their recommendation was the same as the door plate.

 

You did, post 21

The tire manufacturer doesn't recommend anything on a factory vehicle. That's MAXIMUM pressure, not RECCOMENDED pressure

 

Come on guys.......... it's like the silly answers we get on when I should change my oil. There are a ton of variables, and only an oil lab test will give you the best answer.

Same with tires. Many variables. Only chalk tests will answer the question correctly. Keep in mind there are two tests to consider. Tread and sidewall rollover.

Most trucks and econo boxes only consider tread, most sports car guys only consider sidewall. Because of how the vehicles are driven. But it costs nothing to do both, and arrive at the right balance.

As far as door plate goes, mine shows higher in the rear than the front, which is to allow for load. Since I'm normally unloaded, I run less in the rear than the front, and bump up if I'm going to haul a few hundred lbs more than a few miles.

Using the door plate as a starting point is fine, and work from there with your testing.

For the folks that look at the sidewall and see the max pressure number, that's not what the manuf. recommended working pressure is.

 

Uhhh, not sure if serious, lol. 6 psi is a very significant change in pressure, and will cause an immediately noticeable difference in feel and rolling resistance until you get to over inflated pressure levels.

Tire shop put 33psi in my e rated tires. felt like shit. i bumped them up to 40 and it was night and day difference with a 2mpg increase.

 

Post 21 says I go by what the tire manufacturer says, what are you readin?

So I just called Michelin 1-866-866-6605

Michelin recommends (recommends) your Toyota Tacoma use 30psi when using their tires HOWEVER.....When moving up to the LT range of tires they recommend 50psi in front and rear. Their explanation was that when changing tires the new tire must exceed or meet the original load rating. They use a conversion calculator to determine psi for load ratings base don vehicle and tire type.

Heavier rated tires require more psi to maintain optimum performance than a lower rated tire.

Unless we know what types of tires we are running we cannot gather accurate psi ratings for peoples trucks. Not to mention a lot of people will simply be running the wrong psi.

You sir are ignorant, and arguing just to argue.

To more accurately answer the OP's question:

I run Michelin LTX AT2 265/70/16 111s......50 psi F/R
My Ford Michelin LTX AT2 265/75/16......65psi F 70psi R

 

Because I'm Salty

I contacted BF Goodrich 1-877-788-8899 and asked them about a very popular tire on Tacoma World, the BFG All Terrain KO2s. They said the SAME thing.

The original manufacturer recommends 30 psi for a passenger tire at a load rating of 2326 per tire. When upgrading to an LT Tire just as KO2 they recommend a psi of 50 front and 50 rear in order to exceed the factory load rating going from 2326 to 2335 lbs.

I hope this helps everyone.

 

Yep, i have mine at 48/46. low thirties was horrible.

 

Yep, going to sacrifice ride quality and tread wear just to save $2 at the pump.

 

Mind you a 8-9000lb diesel truck only runs 50-55psi front.
