Should car tires be inflated to the printed vehicle specs. or to the specs labeled on the tires?

Use the sticker on the door of the car. The pressure on the tire says maximum pressure, meaning with after the air in the tire has warmed up. The difference between the pressure on the sticker and the pressure on the tire allows for heat expansion and load.

OK, only use what is says on the tire. If it says two different things on the tire and car door, then you obviously have non-factory tires. At this point you only have to use what is on the tire. Using the pressure on the door is retarted, becasue that's for your factory tires. Always use what is on the tire. If you have some sort of rims, and you use the door pressure you will mess up the rims in the matter of months. I just don't understand how if a tire says 25 PSI you would put something else in there. The pressure on the door is meant for the factory tires, and has nothing to do with how the car operates. I won't assume that you have the same factory tires, like everyone else.

Inflate to the spec. noted on the white sticker located on the inside of the driver's door.

The spec. listed on the tire clearly indicates that this is the maximum pressure the tire can hold "if" you wish to load the tire to it's maximum load capacity.

inflate your tires for the vehicle spec failure to do this causes the tires to ware wrong to hard the only ware the center of the tire to soft and the out side edges correct inflation ensures good fuel economy and good tire ware

open driver door should be a sticker with recomended pressure which is a starting point whats on tire is max pressure and it should be under that it will stil be up to you to watch tire wear and adjust and you can type in year and model of car and tire pressure an dfind what it should be

type like 2005 ford mustang tire pressure

cars tires vary as much as the driver of the cars do how much of a load how one drives an dwhat type of roads that are drove on its up to driver to adjust for right wear with each set of tires

PREFER THE SPECIFICATION oN YOUR VEHICLE BECAUSe the specification on vehicals are specific for the vehicle. The specifications on tires are generelised for same category of vehicles! The specs on vehicle are essential for good balancing,handling and grip on the road. IT ALSO ENSURES Good Fuel economy and less wear and tear in tyres. And also get the alignment of tires checked to minimise wear and tear of tyres and enhanced mileage.

on the tire wall... the interior door panel is what the car is recomended for, but the tires will be changed.. always do it by the what the tire says. cant go wrong. if its on the tire, then thats obviously what its rated for

my step dad's been working on cars for almost 40 years now and he's always inflated them to the pressure that's engraved on the outside of the tire wall. it's kind of hard to do this wrong though lol
