I just happened to notice that the tire pressure on my 96 Taco with 15in rims and Michellin tires says 50 Psi, that sound crazy to me can this be right, my wifes 97 LTD runner with 16s says 32 psi.

 

Does it say max next to it? or did you just check the pressure and thats what the gauge said?

 

It says 50 on the tire so I guess thats max, But I noticed while checking tire pressure that it was at 50, so I looked at the tire to see.

 

I have Goodyear LT tires on mine, at least I think they're Goodyear. They are 50 psi, but my parents 04 and 86 are both around 30 psi with stock tires. So I figured since they are Light Truck tires I might as well try 50psi and I didn't notice a difference, so I life them there.

 

Should run whatever is recommended for the vehicle. Im at 29 psi cause it offers the best contact patch.

 

You shouldn't run the tires at their maximum rating unless they are holding close to their maximum load. There really isn't any reason to run the tires at 50psi for a Tacoma that isn't hauling anything.

My tires on my 4Runner are load range D with a maximum pressure rating of 65 psi, but I run them at 40psi for on-road driving.

 

thats all crazy talk.. you can run your tires at whatever you want without going over your max.. but dont go too low, youll get shoulder wear if so.. i work for discount tire and i run my 31x10.50's at 45 PSI and i think the max is 50.

 

well i think the 50 is the max, my bfg a/t's are filled to 30, but while driving, let's say 70 down the highway for 2 hours, if i pull off and check the tire pressure, its close to 60 psi. that higher rating is to compensate for the heating and expanding of the o2, or N.

 

Last time I ran any tires that high, my centers wore down first. Do the chalk method, across the tread, take a little short drive, and look at your contact patch at 45psi, then check it the same way at 30psi. to little outside wears, to much center wears, its just basic science.

 

You beat me to it. If you want the maximum life out of your tires I would inflate them to what you find on the chalk test. You want it to wear evenly from the center to the edge. Proper alignment, tire rotations, and inflation will give you the best results.

You will often times hear people say to bump up the pressure to the maximum to get better MPGs. IMHO if you are paying more for the tires than you are saving for mileage it isn't worth it.

 

To me, tire pressure is dependent on 2 major factors: The weight of the vehicle, and the width of the tire. Tacomas, since they are lighter than other pickups would require less than the max psi listed vaule on the tire.

As already said, the easiest method is to just use a chalk line.

 

x3 for the chalk test.

I keep mine at 45. 50 seems... steep.

 

Mine max at 65. I run at 50 on the highway and 16 off road.

 

35 on my tsl's the trick is not just air pressure alone that the biggest but keeping them rotated too
