Take Care of Your Tires (Part 1)

Posted March 12, 2010 12:55 PM by Steve Melito

At CR4, we get our share of questions about car maintenance and repairs. With content partners such Hemmings Motor News, CarDomain, and MOTORZ, it's only natural for gearheads to find us on the Web. CR4 has Automotive Performance and Car Customizing user groups, too. Whether you're into muscle cars or hybrid vehicles, you'll find a community of interest here.

But what about the more casual car owner – the techie who owns and maybe even loves an automobile, but doesn't dream about changing the oil in a vintage vehicle this weekend? Yep, there's a place here for you, too. Personally, I'm not an automotive expert. Heck, you'd be crazy to let me do anything more than wash your car (and I'm not volunteering). But I would like to share some advice about taking care of your tires.

It all starts with an acronym– PART.

Pressure (P)

At least once a month, you need to check the pressure in your tires. Do this when your tires are "cold", meaning that the car hasn't been driven recently. This can get tricky if you have to drive to a service station to check the air pressure and/or inflate the tires. For best results, spend a little money on a handheld air gauge that you can use at home, and after your car's been sitting for awhile. Record the pressure for each tire. If you don't have your own air supply, drive to a service station with an air machine (and bring some quarters).

With cars as in life, it's important to begin with the end in mind. The goal is to keep your tires at the pressure specified by the vehicle's manufacturer. It's listed on the door post, door edge, glove box door, or fuel door. Some people will tell you to fill a tire to the pressure listed on the tire itself. According the Motorist Assurance Program (MAP), however, "the correct pressure for your tires is the pressure listed on the Placard, NOT what is listed on the tire itself".

Personally, I side with the MAP on this one. But I'm hoping that those who don't will make their case by commenting on this blog entry.

Once you've driven to a service station for air, check the tire pressure again. While you were cruising along and thinking about what you'd rather be doing on a Saturday afternoon, tire temperature increased and inflation pressure grew. So, when you add air to your tires, make sure to account for this difference.

Editor's Note: Part 2 of this series will run during the week of March 22.

On my car, there are different pressures for different loads. I always use the highest load pressure and get extreme long life out of my tires. It makes the springing a bit harder, but after a few days you don't notice it anymore...

In over 40 years of driving like this, I have not found a negative side.......

No, they do not wear out in the middle and even if they did, I still get 2 to 3 times longer life than friends do with their cars.......

"(and bring some quarters)" or if you live in the Northeast go to Stewart's, get the air for free and spend the quarters on coffee.

Also be aware that new tires have a break in period.

So don't go screaming into a tight corner until you have a few hundred miles on them and their traction is what it should be.

Years ago I bought a 1989 Ford Taurus and I put a new set of 35,000 mile rated tires on it that I got at Sam's Club with a friends discount card. Two went bad within a few hundred miles of each other at around 15,000 and and where replaced for free. The next set of tires I put on it was 111 K miles later!

While I was getting new tires put on I found the original paperwork for the old tires in the glove box. When I pulled the original paperwork out no one believed it until they cross checked the tire serial numbers and they all matched the paperwork. They also didn't believe me that they never had any patch work done until all of them had been taken off and visually inspected inside to confirm it. Also the car had never had had any alignment work done to it in that time either.

The first two tires had went over 126K miles and the replacement pair had went over 111 K miles without a single flat and with only one or two air ups a year to adjust for seasonal changes. I always ran them at their rated cold pressure limits as well.

Now I can't get 2/3's of the rated miles out of a set of tires and mystery flats happen several times a year. No holes but rather they just start losing air one day while driving. Perhaps they are just making up for the set that greatly overachieved in life?

Being an ecomodder, I keep my air pressure higher (around 35 psi) than the door panel (29f and 26r psi) and below the tire side wall (44psi). I bought mine at BigOTires. They were only $54 each and are 60k mile tires. I currently have 50k miles on them and they still look fairly new. There is not much of a difference in the way my car feels. I have noticed that it does better in snow and water like this as well. The additional 2 mpg was another addition positive from it. The other sets of tires that I had when I was using the door panel setting only lasted 30k - 40k miles. I got free replacements twice out of this.

Note: I drive a 2005 Mitsubishi Lancer ES with 145k miles on it.

The tyers that i had on my car were pereli P2000 and they formed a bulge in the sidewall for no apparent reason. this was not one tyer but 3 of them.

The garage that fitted them did not replace them as they claimed this bulgeing was caused through potholes in the road.

Some years later I said to a chap that i had just started working with about the bulges in the tyer wall, and he then told me the make and type of tyer that iwas talking about.

Which has lead me to belive that it is a common fault with these tyers.

has anyone else had this same occurance. I have now a Michilin tyer that has also bulged in the side wall for no aparent reason.

All that i can think of is it is wher the side wall matieial stops and the wire braiding for the tread starts pulls the side wall causing the bulge. As the wire brading no longer gose down the side wall of tyers.

If you live in an area where potholes are and/or you dive over kerbs either too fast

and/or at too small an angle, you will damage the sidewalls of many good tires......

Its as simple as that.

If you want to drive over/through such things, you probably need to buy quality offroad types of tires.....
