Tire Pressure Light On?

DO you have a tire light on?  The wrong tire pressure can be very risky and cause your vehicle to become unstable in many circumstances. It can affect your vehicles handling, braking, fuel economy, the life of your tires, and even the comfort of your ride!   Tire pressure is measured in pounds per square inch (psi) is different for each vehicle depending on the tire used, vehicle manufacture, and weight load.

Why Do Tire Pressures Change? 
Tire pressure changes with many factors. Most commonly would be the temperature outside, and damage to the tire from items in the road such as nails.  It is normal for tires to lose 1-2 psi per month due to regular wear and tear.

What Can Happen When Tire Pressures Change?
A tire pressure that’s too high will result in less tire touching the ground.  This makes a harder ride and compromised traction.  Effecting the ability to turn and stop quickly.  A tire over inflated by as much as 5 psi can  damage more easily when run over potholes or road debris. Over time, over inflated tires lead to unnecessary  tire tread wear, shortening the overall life of your tires.

When tire pressure gets too low, too much of the tire is in contact with the road.  Under inflated tires wear prematurely and have the potential to overheat due to unnecessary friction. An under inflated tire only 6 psi may seem small, but actually represents roughly 20 percent of a tire’s recommended psi and could lead to tire failure or reduce the tread life substantially.  Under inflation actually causes a tire to bend more as it moves, resulting in a excessive heat, an increase in rolling resistance and a decrease in fuel economy

How to Ensure Proper Tire Pressure
First, identify the recommended tire pressure for your vehicle.  You will find this information inside of the driver door on a sticker.  If you cant find it there check in your vehicles owners manual. 

If you do not have a tire pressure light get in the routine of checking your tires on a schedule.  This way you wont forget about them.  Use a high quality tire pressure gauge  to be accurate and check pressure when the tires are at air temperature and haven’t been driven more than a few miles.

Remember to check all of your tires, don’t assume the last one is good just because the first ones are at the correct pressure.  Check your spare tire, too, to ensure it’s ready to be used in an emergency.

If your not comfortable doing this on your own, Feel free to bring it by to us any time for a free check up!

Checking your tire psi regularly can help keep your tires in optimal condition for as long as possible,  along with a good alignment and good driving habits. It might just save you a little cash down the road.  

General Routine Maintenance Schedule

Routine car maintenance is mandatory in order to keep a car running properly. The following guidelines are the approximate intervals many car manufacturers suggest auto maintenance service be performed. However, always refer to the owner's manual, dealer or authorized service professional for the particular service and intervals required.

Every 3,000 to 7,000 Miles

The oil and oil filter should be replaced according to the manufacturer's recommended auto maintenance schedule with a majority suggesting the oil and oil filter be replaced between 3,000 and 7,000 miles. Furthermore, inspection of the transmission fluid level, coolant, power steering fluid, windshield washer fluid and wipers, tires and all exterior lights is also encouraged.

Every 15,000 to 30,000 Miles

Replace the air filter every 15,000 miles. Every 20,000 miles inspect the battery and coolant. Most 25,000-mile maintenance service requires replacing the fuel filter. Every 30,000 miles, replace the air filter and power steering fluid. Inspect the coolant, radiator hoses, HVAC system, brake pads and all suspension components.

Every 35,000 to 50,000 Miles

Inspect and replace the battery every 35,000 miles, as needed. Every 40,000 miles replace the spark plugs and spark plug wires, and inspect the ignition system and suspension. These checks are recommended again at 45,000 miles and 50,000 miles.

Every 60,000 Miles

Replace brake pads and brake fluid, radiator hoses, coolant, power steering fluid and timing belt. Inspect the HVAC, suspension components and tires.

Oil changes and air filters are very important parts of engine maintenance; however, a thorough inspection of all engine, transmission, cooling, brakes and suspension components should also be performed regularly. The owner's manual provides a routine auto maintenance schedule based on engine mileage for most cars.

I have been taking my cars to the Car Doctor over the last 5 years and have always been treated with great customer service. Making appointments have always been easy and the service they provide has been the best I have ever had from any mechanic. If there is any additional issues with my car outside of what i brought it in for, they always inform me immediately and let me know if it is a critical issue or if it is something I can delay and I always appreciate that honesty. I will continue to come back for all my car maintenance.

I hadn't know that the management of The Car Doctor had changed hands when I made my appointment. But I was thrilled to receive the same great service from them as I had in the past. Thanks, Matt and Ray!

Don F - 5 STAR ***** 04/15/2019

From calling for an appointment to pick up, our experience repairing our Mercedes was top notch. Chris and Matt were clear about cost, time estimate and responsive to all our questions. We've been Car Doctor customers since the late '70's and plan to continue!

Michael R - 5 STAR ***** 04/12/2019

Saved me over $1,000 and all the staff are very nice and knowledgeable.

Jack - 5 STAR ***** 03/20/2019

Always a great experience. They performed the required maintenance and picked up a bad tail light. Always are great to deal with and honest.

Great service for a great price. Steve is a great guy who never tries to push or sell you on unnecessary work. He is straight-forward, honest, and great to work with.

So happy I was able to have them work on my brakes while I was in Radford for a couple days. I live in Northern, Va but was in town visiting a friend. The place I took my car to before gave me an outrageous price quote that I knew I couldn't trust. Luckily the car doctors did the same fix for a much, much more reasonable price. I will gladly bring my car back here if I'm ever in town again! So happy I was able to support a honest, small business.

Piero Bonamico - 5 STAR * * * * * 1/6/18

I recently moved from Vermont to Washington D.C. I have a 2013 Kia Optima with approximately 113,000 miles, and I let my car go FAR too long before getting service. I didn't want to go to the dealer and thought I would eventually get back to my 20-year-trusted mechanic back home. Well, when the brakes started grinding I turned to Yelp and found The Car Doctor. The experience was wonderful from the moment I walked into the moment they delivered my car back in perfect working order. The price seemed fair, and everything was explained in detail. The was no pressure, and I was given clear options as to what had to happen right away and what could wait. Having a mechanic, you can trust to both fix your car and not make you feel like an idiot is essential. I've finally found mine here in the DMV!

They're an independent repair shop that treats you like a client that they're happy to have.

I love when you can find a mechanic that's as trustworthy as your own father!
