how do you know how much your tires should be inflated to? I have a 2000 Jeep Cherokee if anyone happens to know and I dont have the owners manual cuz the previous owner didnt have it. also, how do you know how accurate the scale is (like when you put air in and it tells you how much pressure it is...how do you know if that is right?)

Look on the sidewall of the tire. There should be a "blurb" telling you the maximum pressure rating for the tire. If you're talking about the pressure guage on the hose at the local gas station it's probably fairly close to accurate.

The correct tire pressure has nothing to do with the number printed on the tire, the number printed on the tire's sidewall is the maximum tire pressure at the maximum load that tire is rated for. The correct tire pressure is in a sticker in a glove box, on the inside of the door, or a door sill or in some cases on the inside of the gas filler door. Usually there are two pressures one for normal driving and one for maximum load when the vehicle is fully loaded. The tire pressure should be checked when the tire is cold. Over inflating a tire by 2-3 psi is usually fine but going to the max is dangerous, first if you use a poor quality gauge you can be over the pressure the tire is rated for, second you are decreasing the footprint of the tire increasing the braking distance and affecting the handling, under inflating a tire is also very bad, causing excessive heat build up and eventual tire failure.

Check the tire placard on your Jeep, which should be in the door frame on the passenger rear door for Jeep's recommendation. Also look at the tire sidewall for the maximum pressure recommendation. Normally it will be around 35 p.s.i. when the tires are cool (haven't been driven more than two miles) or slightly higher depending on the temperature and how far you have driven.
The best way to make sure you tires are properly inflated is to purchase a good quality tire guage and keep it in your glove box. Always use the same gage when you check your pressures and then if you have a slow leak your more likely to be made aware of it.

Best way is to look at the side of the tires sidewall, there will be a number listed as minimum, and maximum PSI (Pounds Square Inch) Since you are the alternate owner, make sure all the tires are the same, due to the previous owner maybe not able to afford the same type of tire at the same time during replacement. Each tire will have a PSI rating, and just follow what the tire's manufacturer states is best for your tire. Always follow what is on the tire, not the manufacturer manual. These days the manufacturer will put a better set of tires on the vehicle, depending on the model you have. Also, if this is an off road vehicle (4 x 4) and you use it once in awhile, I'd suggest leaving around 5 - 7 PSI out of the tires, for off roading. This is due to the impact the tires have to take while off road, so they can absorb any unlevels while off road. Hope this helps.

If you look at your tires you'll find a rating saying max inflation pressure is ??. In your owners manual you'll find the specifications for the recommended pressure.
When I fill my tires, I use my own tire pressure gauge, which I keep in the glove box in all my cars. That way I know it's accurate. I also fill my tires to about 2# less than the maximum allowed pressure rating on the tire. I do this to save gas. It gives a little harder ride, but with the price of gas, I'd rather save the gas.

20 answers and every single one of them wrong.
Unbelievable.
The correct tire inflation pressure for a 2000 Jeep Cherokee is 33 psi front, 33 psi rear irregardless of tire size.
Do not go by what is molded on the tire sidewall, that is simply an expression of the tires maximum load carrying capacity at its maximum inflation pressure - NOT a recommended pressure for that tire on your vehicle.
Any decent store-bought tire guage should be adequately accurate. What's the point of selling them if they are not?

There is only one correct answer for this question and it is , what the sticker on the door says. This is the proper pressure determined by the vehical manufacturer. The pressure that is on the tire is the tire manufacturers maximum pressure, that that tire is safely capable of holding

Look on the side of the drivers door below the latch for a sticker with factory tire sizes and pressures for front, rear and spare. Don't use the max pressure on the side of the tire, that's the tire guaranteed capability.

Look on the door or in the glove compartment for the sticker to tell you the correct pressure. The tire only has the maximum pressure for the tire, not the recommended pressure for the vehicle

take a look on the tires but if your still not sure call you dealership, there was a recall on alot of cars due to the wrong information on the tire, which in the end caused some accidents.
Good Luck! or you could ask the machinc at the gas station for adivce.
