Issues

On my Fourrunner when pulling daily driver duty's it's at 27psi, 35x12.50-15 Mud King's. On my 83 Chevy K10 it's 8psi front & rear, 16x35x15 Bogger's on 15x10 steely's.

30-35 is a good psi to run on a yoda!(for a daily driver) if you have to much air for the weight of the car/truck you will wear the center of your tires out faster, if your psi is to low you will wear the side of your tire out, and just because your tires say "MAX" psi doesnt mean you have to have your psi to that number. An "B" or "C" rated tire 30-35psi. "D" rated 35-max(max if your hauling) "E" 35(if not diesel) then run 40-max when hauling! But now you have to worry about TPMS in 08 and newer rigs!

Holy crap! 50psi for some of these tires? If it works for you then awesome. I have a 98 Jetta I use as an SCCA car, and was always told on her track tarmac ready W rated 245's to use no more than 44psi. Now I understand a track car with soft compound tires is going to run alot of heat in the tires, with speed and track temp and the corners, thus raising the pressures. But I saw alot of guys blowing any less of a tire at even 40.

I tend to run 24psi on the 35's on my Jeep and 34 on the stock sized tires on my runner.

There's so many variables when running tire pressure I think it is really misleading to base your decision off of what other people are doing.

I live in BC, I run on wet pavement an awful lot. I'll sacrifice fuel economy and tire wear for more traction so I'm willing to run a bit lower tire pressure most of the time.

If I know I'm making a road trip, I air up a bit.

If I'm pulling a trailer, I air up.

If there's snow on the road, I air down.

If I'm yanking a ford out of the mud, I Air down.

If I want to play on the sand dunes in Oregon I air WAY down.

If I'm hitting the trails, I'm prepared to go up and down at my whim.

The important thing is to know is that at the end of the day your tires are the extension of you that touches the road. Understand what airing up and down does, and do so accordingly.

I strongly recommend carrying a valve tool and a compressor in your truck all the time. A few PSI can make the difference between needing a rescue and being able to do a rescue.

While tire wear and fuel economy are good motivators for setting your air-pressure, saving money should always take a back seat to safety when it comes to running your rig.

I run 30lbs in my 31 10.50 15s... and ur chalk test is really worthless.. as if ur doing ur test cold ur tires is going to blow up.. and if ur doing it warm its still cooled down and shrunk to much.. a tire done on this test should be found then back the air pressure back down for the expansion its going to make on the highway..

and reading the max tires pressure is not what u want.. our short bed, 4cyl, 4x4, 94 pickups way about 3400 pounds... now that same tire could be on a s-10 weighing 3900lbs? or a full size Chevy weighing 4400? now all these trucks arnt going to take the same air pressure!!! with the heaviest one taken the most pressure and the lightest taken the least pressure

Car & Driver did some definitive comparisons of tire pressure vs mileage a few months ago over a closed course with test equipment to verify the data. Bottom line on pressure was to air them cold to 5 lbs over the recommended pressure. Any higher than that compromised cornering, stopping and ride quality with little additional benefit.

I run my Firestone Destination A/T's at 37 lbs cold with good results. 30,000+ miles with rotations every 5k and the wear has been excellent and even all around. Last summer's roadtrip totalled 4,000 miles, 95% interstate driving and the rest was suburban plus about 40 miles of dirt and gravel logging roads. Average interstate speed with GPS was 71mph, above that mileage dropped off quickly to 17.8 at 75mph due to wind resistance. Using GPS to validate speed and correcting for the taller 70 profile, I documented 19.9 mpg overall. Taking the crossbars off the roof rack gives you a few 10ths and every 100lbs of additional weight drops mileage by .1%. Best advice for better mileage? Watch the traffic flow and drive it like you have no brakes, getting off the gas as early as possible when you see traffic is stopping. Drive smoothly and use the cruise when traffic permits.

I pay close attention to traffic and lights and pop it into neutral if I'm coming up on a red light. It might piss the guy off behind me, but why be in such a hurry to get to a red light? I tend to not use my cruise control because I find that it actually uses more gas when driving in hills and dips. Going downhill it will let off, slowing the vehicle down too much then it will give gas to speed up to compensate. Then if an uphill section is coming up it will be going way too slow at the bottom of the hill and overcompensate giving lots of gas. It might keep me within the speed limit(or whatever I set the cruise at), but I'd rather coast down the hill, gain a bit of speed and moderately accelerate up the next hill. I hate driving with CC because it's not as efficient as most people think it is. It can't predict the ups and downs of the road.

i run 34 all the way around on my new tires 265/70/16....my stock tires 245/75/16 toyota recommended 30 all the way around...and toyota recommends 29 front and 32 rear for 265s which is the size i got now....but i did that on other vehicles in the past and i never really noticed any difference....it's easier to run 32 all around or 34 then you don't have to adjust the pressure when you rotate your tires...there's really no difference in gas mileage or wear....the differences are so little...the handling is still the same etc...i would never go above 35 cuz it makes the ride bumpy (harsh) when you hit bumps in the road...unless you have a load in back or are in the snow or something i would stay between 32-34 all around
