When Are Your Tires Worn Out?

Hey Princeton area drivers, are your tires worn out? What is the standard for our NJ streets? How can you tell on your vehicle?

While there may be legal requirements for the Princeton area, there are safety concerns that go beyond meeting minimum replacement mandates.

Two-thirty-seconds of an inch is the depth of the tire tread wear indicator bars that US law has required to be molded across all tires since August 1, 1968. When tires are worn so that this bar is visible, there's just 2/32 of an inch – 1.6 millimeters – of tread left. It's that level of wear that's been called into question recently.

We're referring to the tread depth on a tire, it can't move surface water out of the way and you start to hydroplane.

In a safety study, a section of a test track was flooded with a thin layer of water. If you laid a dime on the track, the water would be deep enough to surround the coin, but not enough to cover it.

A car and a full-sized pick-up accelerated to 70 miles per hour, or 112 kilometers an hour, and then made a hard stop in the wet test area. Stopping distance and time were measured for three different tire depths:

• New tire tread depth
• 4/32 of an inch, or 3.2 mm
• 2/32 of an inch, or 1.6 mm

So what happened with the 2/32 inch/1.6 mm tires on the car? Get this – when the car had traveled the distance required to stop with new tires, it was still going 55 mph/89 kph. Stopping distance was nearly doubled to 379 feet/116 meters, and it took 5.9 seconds.

Wow! That means if you barely have room to stop with new tires, you would hit the car in front of you at 55 mph/89 kph with the worn tires.

Now, with the partially worn tires – at 4/32 of an inch, or 3.2 mm – the car was still going at 45 mph/72 kph at the point where new tires brought the car to a halt. It took nearly 100 feet, or about 30 meters, more room to stop and 1.2 seconds longer. That's a big improvement. We can see why Consumer Reports and others are calling for a new standard.

Of course, stopping distances were greater for the heavier pick-up truck.

How do you know when your tires are at 4/32 inch or 3.2 mm? Easy; just insert an American quarter into the tread. Put it in upside down. If the tread doesn't cover George Washington's hairline, it's time to replace your tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.

You may remember doing that with pennies. A penny gives you 2/32 inch, or 1.6 mm, to Abraham Lincoln's head. The quarter is the new recommendation – 4/32 inch, or 3.2 mm.

How do people feel about replacing their tires earlier? Well, tires are a big ticket item and most people want to get the most wear out of them that they can. But do you want that much more risk just to run your tires until they are legally worn out?

For us, and we would guess for many, the answer is "no".

Can Your Car Last Another Year?

Have you checked out the price of new vehicles at Princeton car dealers? Ouch! Add financing and insurance and a new ride may not seem so attractive. A lot of Princeton, NJ, folks are hoping to make their cars last a lot longer.

Fortunately, with the current state of automotive engineering and manufacturing, there's no reason a modern vehicle can't be made to last for a 150,000 miles (250,000 kilometers) or more for smart Princeton drivers.

The old adage: 'a stitch in time saves nine' is really true for Princeton residents when it comes to car maintenance. A great example is coolant service.

Over time, coolant becomes corrosive and actually starts to damage your radiator and other parts. Smart Princeton drivers have their cooling system service taken care of right on schedule at KPS Princeton Garage.

Ditto for your power steering system, brake fluid, air conditioning system, differential and transmission. Of course, oil changes should be done right on schedule to avoid the build-up of harmful oil sludge.

Don't let your brake pads go too long before they are worn to the point that your rotors are at risk. Preventative auto maintenance at KPS Princeton Garage is a great way to keep your operating costs down.

Replacing belts and hoses is much cheaper than repairing the damage that can be caused by failure.

We know that this is a lot for busy Princeton area drivers to remember. Let the team of automotive professionals at KPS Princeton Garage keep on top of this stuff for you. We can tell you what your vehicle manufacturer recommends and help you develop an affordable plan to take care of it.

Bottom line – do routine maintenance on schedule and you will reduce operating costs, prevent repairs and maintain your warranty coverage.

Let us take good care of your car at KPS Princeton Garage in Princeton, and it'll take good care of you.

Fuel System Cleaning at KPS Princeton Garage

Is your vehicle sometimes hard to start early in the morning? When you turn the key, does it hesitate or stutter? If so, the problem could be the result of a dirty fuel system. Your vehicle's fuel system starts with the air filter and ends in the top of your engine. Over time, different parts of the system get dirty, which robs you of performance and hurts your fuel economy.

Most Princeton vehicles have fuel injectors, rather than a carburetor. Fuel injection systems have fewer problems and require less adjustment. But they still need to be properly maintained. This is why your owner's manual has a schedule for cleaning your fuel injectors and other parts of your fuel system.

Some Princeton residents are interested in buying fuel system cleaners that they can pour into their gas tank. You can do that - and there are lots of great products available that can help maintain an already clean fuel system - but these products cannot do a major cleaning. For that, you need to see KPS Princeton Garage. KPS Princeton Garage has the professional tools and chemicals to really do a complete service.

KPS Princeton Garage uses a process that gives your vehicle a deep, professional fuel system cleaning. You need to remove particles, gum and varnish from your fuel system and get those injectors running cleanly and efficiently. After a professional fuel system cleaning, you'll notice more power, better fuel economy and reduced exhaust emissions.

The cleaners also help prevent rust and corrosion in your fuel system and lubricate engine parts.

Fuel system cleaning is just one of those recommended service items that help keep your vehicle running strong. As with all maintenance, it can help avoid repairs that often result from not taking the right preventive steps. Princeton residents will notice the difference in how well their vehicle runs. Check with your friendly and knowledgeable pros at KPS Princeton Garage to see when your vehicle is scheduled for a fuel system cleaning.

An ounce of prevention really is worth a pound of cure for Princeton vehicles.

Trip Inspection at KPS Princeton Garage in Princeton

Princeton area drivers love their vehicles. And one of the most enjoyable things about them is taking a road trip. Freedom from daily schedules, new sights and the open road – it's great! But there's nothing like vehicle trouble to bring the fun to a grinding halt.

Now Princeton drivers can't always avoid problems, but you can take steps to reduce the probability of getting sidelined on your trip. The first step is to look at your trip plan from your vehicle's perspective. What kind of roads will you be traveling – winding NJ byways? Purple mountain majesties or fruited plains? What weather conditions are you likely to encounter? How far will you travel each day? How much weight will you be hauling – passengers and luggage? Pulling a trailer, roof top carrier or ATVs? Will it be dusty?

Prepared with answers to these questions, you can schedule a trip inspection at KPS Princeton Garage in Princeton to help you prepare your vehicle for your big adventure. A lot of our Princeton customers prefer to go through this exercise with their friendly and knowledgeable service advisor to get their input and make sure they haven't overlooked anything.

A great place for Princeton drivers to start is with the tires. Inspect them for tread wear and proper inflation. Is it time to rotate your tires? Replace them? Are they up to the job? You wouldn't want to drive regular highway tires on a muddy off-road adventure on NJ rock-crawling trails. 

Shocks and struts play a major role in both driving comfort and safety. If they need to be replaced, you'll really be glad you did once you hit the road. Is it time for a wheel alignment? Fighting a car that's pulling to one side all day can be tiring and dangerous. 

And don't forget your brakes. Any strange noises, grabbing, soft or hard peddle feel? If there is any doubt, get a brake inspection at KPS Princeton Garage in Princeton before you leave.

Moving under the hood, have a belts and hoses inspection. If something is excessively worn or near failure, the stress of a long road trip might just be the straw that breaks the camel's back. Talk to your service advisor at KPS Princeton Garage.

Your engine air filter will be inspected. Your car's air filter will process 12,000 times as much air as the fuel burned by the engine. If the filter needs to be changed, you'll notice improvements on your trip.

How close are you to your next oil change? Will you be able to complete your trip before it's due? If not, just get it taken care of before you go so that you don't need to interrupt your trip. In fact, a full service oil change at KPS Princeton Garage is a great idea because they will top off all your fluids and check to see if any other maintenance items are due, such as transmission or cooling system service.

Do you notice any unusual odors in your vehicle? If so, it could be as harmless as a dirty cabin air filter. But if it's an exhaust leak, it could be fatal for Princeton drivers and their passengers on a long trip. Of course you'll want to be comfortable, so get an air conditioning service if you aren't getting the cold air you’re used to. 

Are your wiper blades still working well? If not, that is a quick and inexpensive fix for Princeton drivers. Headlamps are often overlooked when planning for a trip. If you haven't changed the bulb in six months or so, replacement bulbs will really light up the night on your trip and provide the necessary after-sundown visibility.

All the items mentioned are part of any good vehicle maintenance plan. These are things that you want to take care of anyway, but they all become more important as you plan for your trip.

They will always save you money in the long run and may prevent inconvenient stops and delays on your trip. After all, you wouldn't want to miss the world's largest ball of string, would you?
