PSI in stock tires P245/75 R16

I am looking for the SAFE max PSI in stock tires for better MPG. The tires are P245/75 R16 on the tires it says, Never exceed 40 psi, door sticker says 30.

I have read on line some are running 38 in all 4. I am looking for the SAFE number, I do not go off road or carry any loads.

Thanks in advance JIM

 

Always go by door IMO

 

i dont have stock tires, but i have 245 E rated and i run 45+- front and rear never have an issue.

 

why?

always go by the max PSI on the tire, tire manufacturer knows better than vehicle manufacturer. just my opinion.

 

32 psi here.

 

Use the door pressure as a start point and do the chalk test. Then add pressure as required untill you get an even wear off on the chalk you rubbed onto the tire. That way you will know that your contact patch is even and so will the tire wear. Even contact patch is the best for handling and braking too. Use the max pressure on the tire sidewall as your upper limit. Lots of pressure will cause your tire to round out so that only the centre of the normal contact patch is touching which will improve your fuel mileage but its not as safe for braking and will wear the center of the tread more.

Just use your judgement and some common sense.

 

Not always the correct approach. The numbers on the door are for stock set up with an unloaded vehicle.

You better call your tire manufacturer for some clarification, you're way off.

Best and correct response.

 

I run 35 psi in my stock dunlops.

 

umm, incorrect. the companies work in tandem when specifying OEM, and
the engineers both at the tire company and at the auto manufacturer
know a lot about tires, specific automobiles, computerized safety systems, and drivetrain.

door sticker pressure is the most correct standard to follow when
the vehicle is shod with oem meats. are variations in this pressure still
completely safe ? yes, within reasonable limits, and with regard to load and terrain

 

^^ this guy!

I thought he was running stock tires that's why I said run door pressure. I very much agree with the other guys on here don't put them at the max pressure that the tire says unless you do what this guy ^^ said and it works out.

 

I start at the door pressure and then noticed that the truck would "wander" with a little shudder on the freeway. So, I adjusted the pressure up and down until it all settled down. The truck likes 33psi front and rear so that's what I run and have re-set the TPMS for that pressure.

I agree with Ray. Replaced dunlops with Mich LTX MS2 (P245/75/16). Truck seems to like 33 psi, door sticker is 30.

Seems like buried away in the owner manual said add 3# to door sticker for "sustained high speed driving".
