Agreed, if the tire says max 44psi,, please reduce them down to 35. the correct psi really has to do with the tire you have on your car. the psi numbers on the car are with the tires that came with the car. a rule of thumb, is to look at the contact of the tire. when you park you will see how the tire is contacting the road. if it looks like you are over the shoulder edge then you need to add psi. if you are away from the outside shoulder area, then lower the psi.
That would be my assumption too, without the tire brand it is harder to confirm. The PSI on the tire wall should just be the max PSI.
Side note, remember who the tech is that filled them up to 44psi and don't have him work on your tires again and also you may want to let his supervisor know what he is doing because it's going to blow out tires at some point. its likely the max pressure that tire can handle and depending on the temperature outside, it will likely go over the 44psi during the operation of that vehicle using those tires. its dangerous
Doesn't matter what is on the tire. Go by the sticker in the door jamb, or 1-2 PSI higher if you prefer. If you are driving in heavy snow, lowering it a bit is better.
I would run 35 psi in them. A tire always has the max psi on the sidewall and that is all. That being said don't ever put just 2 winter tires on. Now you will have better traction on the front but the back of your car can easily slide out of control while braking or turning. It's very dangerous and any reputable tire shop won't do it because of the liability. So once again, never install just 2 winter tires.
The sticker on the car says 32, so it is obviously OK to do that. Some people like a little more PSI, but that is just their own opinion, and only do that on dry pavement (no snow or ice).
The sticker is a manufacturer suggested psi for the car and the specific tires that came with the car. The needed psi is tire dependant. Just look at whats making contact with the road. If it is wider than the shoulder edge of the tire, it needs more psi. If its narrower than the shoulder edge then lower the psi. People keep saying 35 because that typically is a norm average to get the tire so its shoulder edge to shoulder edge and it wears evenly across the tire. My saturn says 28psi but with the current tires it has that was way too low and it finally wears right at 36psi up front. It really depends on the tire u have put on the car. The door sticker from the manufacture gets u to the psi needed for that vehicle but adjusting it is needed for the brand of tire u have on it so that it wears correctly. usually its within a few psi from the manufacture's sticker they put on the door. hope this helps
Indeed. It's the car specification that determine correct PSI, not the tire capacity. Just like cooking
: your oven may be able to reach 500F but that doesn't mean you cook everything at that temp !
That would scare the crap out of me. You could so easily loose control and a wreck could cost a lot more than 4 winter tires. I just finished swapping my winter tires and wheels on my 2017 Corolla iM, the wife's 2010 Prius and our 2017 RAV4 today. Here are my winter tires on the left and my 3 season tires on the right. The other pic has the winters ready to install for my Corolla iM and RAV4. I had just finished my wife's Prius.
That is true for tire size, but I don't believe that is correct if you are talking about tire brands or models. Many vehicles come with different tires depending on trim level, but the sticker PSI is always the same for a particular tire size.
Valid points thanks. Ive just noticed over the years for every set of tires ive had to put on different car that ive had to adjust the pressure so they wear evenly across the tread of the tire. And each tire has had to have a different psi so it wearing shoulder edge to shoulder edge. Being an engineer i cant help but make a science of it. Its bad enough that when i redo the wheel bearings and suspension that between a micrometer and measuring tape the alignment is perfect when im done and the alignment shop doesnt have to make adjustments. I ocurrently have 30 sets of tires experience on this with all the different cars ive had and the current 5 i have right now. Most of them have been within 3psi of the recommended cold pressure. But two of my cars with the current brand tire on them ive had to raise the psi 8 psi over recommended pressure because they are past the shoulder edge of the tire. Doing this with all my cars, all my tires wear evenly across the tread. And i check with a depth gage often probably to a sickness level..lol.. Anyway just sharing what i have learned from all the different tires ive had and worn through over the years
