hey guys, lately I've had my tires at about 36psi in front and 30 in the rear, just wanted to get some ideas on what you all keep yours at

 

~34 psi around was about what I used to keep them at on the old 1st gen. CHeck your door jamb for the recommended pressures. I usually look at these and then up them about 2-3 psi to fit my driving style.

 

In order to have the longest life of a tire you must keep a higher (but not past max) psi in them. Using your door jam for reference only shows you what pressure to put in the tires Toyota put on the vehicle when first purchased. If you have a 35 max then put 32. If 44 then put 40. I have a 65 max on mine and run 60. If 80 I would put 70. Obviously this is for on road driving of course. This will give you the longest tire life aside from a well aligned suspension.

 

well my truck came with smaller tires so my door jam doesn't show the right info for the tires on it now..

I have really stiff shocks so I dunno if I could handle a bumpier ride by going over 36psi,. my neighbor put his to 40 something and his truck still rides smoother than mine, but he doesn't have heavy duty shocks either.

 

My dads tacoma double cab has all tires at 26psi. I'm getting my own tacoma ext. cab next week sometime.

 

I haven't seen a door jam on a 2nd gen with pressures for 31" tires. Mine came with 31"s but the info isn't there. I normally run 32 psi, which is higher than what's listed on the doorjam. I ran 32psi in my cars for years without damage, and with slight increases in mpg.

Too much pressure will decrease the contact patch with the road...great for gas mileage but lousy if you need to stop a 4400lb beast in a hurry...The ride sucks also.

 

Mine doesn't list the 31's either. I'm running 34 psi in all 4 and the wear seems to be even across the tread. I lower the pressure to 30 in the winter because of the change in the weather (wet mostly, some ice).

 

Prime example of why you should never do everything you read online

 

i keep mine 36 in the front 32 in the rear.
rock on,

I have many years experience in the field and an AAS Degree in Automotive technology. Any compitant tech who had any experience with tires, alignments, and susp. would tell you the same thing. You think I don't know what I'm talking about, but you give no evidance otherwise. YOU are a prme example of why you should never do everything you read online.

 

Competent...

 

The shop that put my tires on set them to 46 psi front and rear. I too have rather stiff shocks, and let me tell you, that was the worst freakin ride home I've ever had. Every little tiny bump sent me jolting...I hate to even try to remember what hitting speedbumps was like.
My manual suggested keeping them at 26 psi, but since my new tires were bigger, I bumped it up to 30. WAY better.
In a nutshell, I'd advise going maybe 4-5 psi higher than what your manual suggests, since they're bigger tires.

 

I can certainly appreciate the fine education you received, it just shines though, but you are not correct about tire pressures.

A tire's pressure is determined BY the load. Making a blanket statement that all tires should be inflated to some arbitrary number is ludicrous, and dangerous.

 

Exactly. Put that same 31" tire on a bigger truck with more weight and you are going to need to fill the tires with more air. The air pressure stated on a tire is safety requirement. You shouldn't go over it. It is a rating for what the manufacturer guesses would be the heaviest vehicle the tire is installed on. Put the tires on a super light vehicle and you don't need as much air pressure to hold the vehicle up. Always judge the tire by it's contact patch(as long as you are below the max pressure).

 

I ran my BFG A/T's at 35 all around on my Runner...they wore just fine.

Ok, how's this? The PSI for your tire should be what ever makes you happy.

 

I have stock but the only thing I will mention is that stock front on my runner is lower than rear, 26 front and 35 rear. Maybe you should keep a similar ratio or atleast keep the front lower than the back.

 

Mr. Kennedy, could you please explain why less pressure is better in the front than the back? In an unloaded truck about 65% to 75% of the weight is on the front tires.
Is there any rhyme or reason to that statement or are you " just sayin' "?

 

Because its on the plate inside the door, I dunno.

But I may have read it wrong becuase I was down on the beaches the other day and it is suggested that you keep it at about 14< front and 13< in the rear.

Also are you really from the North Pole, thats sick.
