mkgarrison5 · 07-20-2007, 05:35 AM

Maybe I didn't make it clear that I am, in fact, running stock tires.

As to your chalk test, I've got nothing but dirt roads and driveways... but I could do that test if I needed to. The question I have is this: How do you explain the fact that a tire at rest is quite different from a tire traveling at 60-80mph. A good radial will deform (the "patch" is much larger at speed). This, I would think, would mean a chalk test would work only on a more rigid sidewal, such as late model designs, or a non-radial tire. Am I wrong?

I'm thinking my mistake was in not rotating the tires. Although I've never needed to do that on a radial tire. Just swapping them from front to rear would have made a big difference.... guess we live and learn.

32/11.50/15 on 15X7 Toyota OEM alloys @25 psi all day every day

LowerArcadia · 07-30-2007, 07:11 PM

I have a 05 4Runner with 265/65 r17 tires. The sidewall say 51 psi maximum. What psi should they have when cold?
The have been staying at 32-35 psi. The tires appear to be getting some extra wear and the Air Pressure light stays on in the dash.

Any info would be appreciated.

Nate08 · 09-20-2007, 05:48 AM

I try to stay around 35 PSI, but since my nitto's are 65 PSI Rated, I might go to 50-55 PSI for better gas mileage.

04 Rocko Taco · 09-20-2007, 05:50 AM

I usually run 35 psi in my 32" A/T's. On long road trips, I run on up to about 45-50 psi, for gas mileage. lol.
Offroad if its slick (muddy/wet) I run down about 15-20 psi.

John LTD · 09-20-2007, 06:02 AM

I usually run 40 psi for the road. And some where between 25 an 17 off road, depending on how sandy it is.

X-AWDriver · 09-20-2007, 06:07 AM

At 50+ psi your Nittos will wear very poor and handling will be sacrificed and is kinda dangerous when recommended pressures are around 32psi.

I run my Nittos at 35psi with no ill wearing and handling is still quite good. I gert what nearly every other 4Runner gets and even with my being a bit of a leadfoot I still get about 17mpg in the city,that number has jumped to almost 21mpg on hwy trips.

cubuff4runner · 09-20-2007, 07:00 AM

I run 18-20 PSI on the road, but that is because I have a 13.5" Bias tire on a 8" rim.

terryjmatthew · 09-20-2007, 07:41 AM

35 PSI on the street. 305/70R16 BFG Mud Terrain KM's on OEM 16x7's.

Run them any lower than 30 and they get pretty squirly on the street.

OSU4Runner · 09-20-2007, 07:44 AM

I run 45 psi, I think it rides better on the road, and helps out the MPG

Hoopster · 09-20-2007, 10:20 AM

36 front and 35 rear approximately depending on my mood. I know that higher pressures would help mileage some but I don't want a harsher ride on the street.

CJM · 09-20-2007, 10:28 AM

Chalk test the tire:
1. Take some chalk and draw a line ACROSS the tread of the tire.
2. Drive about 50 feet, get out and check the line wear.
2a. Line is worn on inside the tire is over inflated, line is worn on outside under inflated.
3. Adjust pressure till entire line is evenly worn away.

Coincidently running about 10lbs less than what the max pressure is, is usually the number you will come up with.

Remember the more pressure the better mpg but stiffer the ride. Less pressure= less mpg.

MillerPKA · 09-20-2007, 10:29 AM

32 all around right now

mokai · 09-20-2007, 12:11 PM

I run 45 front and 50 rear in 265/70 16 BFG A/T's..65 psi max..BFG said that they recommend these pressures for my Tacoma..I had some weird vibrations @ 55 miles per hour if I run less than these pressures.. The tires are wearing evenly too..

KevinInSac · 09-20-2007, 12:43 PM

I've got 35 in the rear and 40 in the front. My front is so much more heavier than the rear that they run flat to the ground, where as my rears are balooned a little.

unitofstuff · 09-20-2007, 12:54 PM

35psi all around in my 265/75/16 MT/R's. They're much smoother with less vibration at high speeds than at 40psi.

mattdon · 09-20-2007, 01:19 PM

My tires say 55 psi and i run around 45 on road and 20-25 in sand

dijlop · 09-20-2007, 02:42 PM

i gave up on tires. too costly. i just run on my rims. kinda a rough ride, but i get great gas mileage!!!

(disclaimer, if anyone tries this, i accept NO blame. thank you, that is all)

spacewrangler · 09-21-2007, 07:18 AM

i run 32 lbs in a 265/75/16 ...anything more than that and it kills ride and makes the truck jump around a good bit over bumps. i guess that's what i get for running a D load range tire on a truck designed for a C load range.

Rick F. · 09-21-2007, 10:24 AM

33 PSI all around. I air down to about 24 in deep snow.

ARB1977 · 09-21-2007, 10:35 AM

42 psi all around, the funny thing is that the tires balance and wear better at that pressure.

bob200587 · 09-21-2007, 10:48 AM

32-35

jdog19 · 09-21-2007, 08:16 PM

60lbs max on toyo m/t are 80lbs

bruzer · 09-21-2007, 08:37 PM

Right about 20psi right now.
