Recommended Tire Pressure (PSI)

Hello guys,

Looking for some advice on what tire pressure (PSI) to keep on your tires.

I recently got Falken Wildpeak AT3/Ws size 275/55/20. I reached out to Falken and they suggested 30 PSI in the front and 33 PSI in the rear.

Seems pretty low to me since I have always put around 33-35 PSI for all 4.

I have 2WD if that makes any difference. Falken also explained it would be the same PSI all year round unless your TPM light goes off after driving for a while. FYI they are Extra Load (XL) tires.

Any insight would be appreciated thank you!

 

I run 35psi all around personally. If they are E rated tires then you can go much higher.

 

The door placard on my 2018 2WD Tundra says 30F, 33R (18"wheels). I found that when in cold weather (I visited my brother in Oregon), the pressures decrease across the threshold and the TPMS light goes on. It turns out the threshold is 29PSI. So I bumped my pressures up 2PSI to 32F, 35R and that solved it.

You can also reset the parameters by holding down the tire pressure button under the steering wheel if you want to run 29 with no light.

 

Interesting, never knew that. Thanks!

You won’t take the advice of the people that actually make the product so you turn to some random dudes on the internet?? Interesting.

I have Michelin LTX A/T2s in 275/60/20 and Michelin said to run 29 psi all around.
Been doing that for years with 30k miles and 5k rotations and still lol like the day I bought them.

So 30 and 33 don’t seem too low to me.

 

How’s that 10k mile oil change interval recommendation working out?

 

For vehicles that actually fall under the 10k mile oil change interval they are doing just fine.
However a large portion of vehicles do not fall under Toyotas 10k mile suggestion they actually fall under the 5k interval. Idling is what many folks tend to over look, school car line, drive thru, traffic.
While 10k is an interval it is slightly disingenuous. But tire PSI is a bit different scenario than oil change intervals.

• If the vehicle operation meets the standard criteria for "Special Operating Conditions" such as: driving off-road, on dirt roads, towing a trailer, making repeated short trips under 32˚ F, or extensive idling; the engine oil must be replaced at 5,000 mile intervals, regardless of what type of oil is used.

The standard is excessive idling. When I think of excessive idling, I think of taxis, police cruisers, or work trucks where they idle hours per day - not 10 minutes waiting for kids or 5 minutes in a drive-thru. Maintenance recommendations should be viewed as the minimum required maintenance to get through the warranty period. If you plan on keeping the vehicle for a couple hundred thousand miles and a couple decades, I’m going to replace things like the coolant, trans fluid, transfer case oil etc yet those items never appear in the standard Toyota maintenance schedule. It’s almost like these manufacturers want to sell you a new vehicle every 5 years…

 

Yet tons of Toyotas go hundreds of thousands of miles on these intervals. Are there ones that have problems sure but most truck along just fine.

However maintenance schedule and proper PSI for the tire to perform as it should isn’t quite an apples to apples comparison.

 

Having lower PSI gives you more traction and softer ride, having higher psi gives you longer tread wear and better MPG. Adjust PSI to what you're looking for, if you're going on sand you can go way down below recommend PSI. The door numbers are just a recommendations.
