Seems like an easy question, but I couldnt find anything when looking threw a few pages of searches.

Anyone know?

 

I use 40 psi

 

On the sidewall it will tell you what the max PSI you should run in the tires.
Don't pay any attention to what this says or reads, start with 40 PSI and
see how they feel while you're driving. If that feels to rough drop is down
2 PSI until they feel comfortable. The tire shops always want to put 40 in
front and 42 PSI in my rear but they feel like rocks that way so I run 37
both back and front.

 

Ok, so Ive got one guy running 37, the other with 40

Shall I split the difference

Let me try 37 first. See if the wife thinks its OK.

Thanks!

 

37 is his preference. 40 is what the shop I use suggest, and they all run 40 in their 20 inch tires. It could depend on the tires, I run Falkens, he may be running Toyos. But either way I would run 40 IMHO

 

Hello wadd3456. If it is the stock size tire, use the engineer recommended tire pressure listed on the vehicles tire placard, (also listed in your vehicles owners manual). The tire placard will be located on the end of the door, or where the door latches to the car and is usually a small white decal about the size of your palm. Other locations for the tire placard can be on the back side of the glove box door, on the back side of the fuel door, or on the back side of the trunk lid.

If the tires are not the stock size, then things get a little more complex. You'll need to find a load/inflation chart, (can be had at your local auto center/tire store in the 2007 Tire Guide), and determine the correct safe load carrying capacity for the non-stock tires. You want to at least equal the safe load carrying capacity of the O.E. size tires in order to be safe. Under-sized, under-inflated tires can blow out.

It is worth noting that the maximum recommended air pressure listed on the sidewall of the tire is not the recommended air pressure, but merely the maximum pressure and not to exceed it. Inflating a tire to the maximum recommended air pressure can cause the vehicle to ride too hard, rapid tire wear and also can result in damaged/bent wheels. Over-inflated tires don't absorb road impacts very well and have less, "give", in the sidewall, resulting in the rim taking the full brunt of the impact and bending it. A tire that rides this hard also causes the MacPherson struts to wear out faster, along with all the other suspension components. So for many reasons, setting the correct air pressure in your vehicles tires is a very important issue.

I hope this has been of help. Good luck with it.

Good info, but if he is running 20's the door reading wont help, thats for stock tires

sorry, too much info, must have missed that part

 

Okay, I'll forgive you this time, but if it happens again Santa Claus will do a burn out in your driveway at 3:30 AM when he drops off your presents! lol

as info my Falkens say max pressure 50 psi
if santa does a burn out I would be stoked, but only if he was in a G other than mine. I think he is bringing me something special

 

Make sure you don't put 50 psi in your tires, or they will wear out very quickly and you will have the other issues I mentioned above too. Use the O.E. tire placard air pressure recomendations, which I would guess is somewhere around 30-35 psi.

I hope Santa takes care of you.

never 50, I use 40. But they are off now and the winter set is on, stupid cold weather

 

[QUOTE=snavematt]as info my Falkens say max pressure 50 psi.
Most tires have a reading on the sidewall that says max pressure 50 PSI, but
unless you don't enjoy having teeth I would not have anything more than
40 PSI in any tire......and that's too rough for me. Ca. freeways are really
terrible with potholes and uneven surfaces so my choice is always 37 PSI!
