patch between your tires and the road typically covers no more than one square
foot...in total! Make the most of your connection with the road and enhance your
vehicle's ability, safety and cost of operation.
I haven't had a flat in years. Tire technology has
come a long way, hasn't it? Do I really need to pay close attention to my
tires? Yes, technology has moved forward along with the rest of the
automotive industry. However, tires are subjected an incredible range of
conditions and over or under inflation and the degree of wear can significantly
impact your tires' ability to perform well under these
Can't I tell if my tires are properly inflated just by
looking at them? Not necessarily. If a visual inspection suggests your
tires are over or under inflated, they are almost certainly very far out of the
safe inflation range.
How do I measure my tire pressure? How do I fill my
tires? Tire pressure gauges are available just about everywhere in a wide
range of styles and prices and are available with digital or analog dial
readouts. Some gas station air compressors are equipped with gauges, but since
you can't always count on them being there. You can buy a gauge for as little as
a few dollars. Here?s how you measure pressure and fill your tire:
a. There's a
little stem (valve stem) that pokes out through your wheel with a small screw
cap on it. Undo the cap and press the business end gauge firmly against the
stem. This releases a valve that lets some of the air out of the tire. You
should hear a short burst of air and you should get some kind of reading. If it
sounds like the air is continuing to come out or the dial/digital display/gauge
stick hardly registers anything then you probably haven't pressed firmly and
directly enough and are just letting air out of the tires. You'll have to reset
the gauge to zero before each measurement.
b. You must take the reading
when your tires are "cold", that is when they haven't been driven very far,
generally under a couple of kilometers. Check in your Honda manual.
Use the same technique when filling up your tires; if you don't press firmly
enough, you'll simply just release air from the tires. If you have a good
connection, you will probably hear the air compressor working. If you don't have
a good connection, you'll hear air hissing and escaping around the valve stem.
Remember: use a firm direct touch to fill the tire and measure and a light touch
to release air.
How much air should I put in my tires? Your
tires, for example, may say that the max pressure is 35 psi. That is only the
maximum pressure that the tire can safely accommodate; it isn't necessarily the
ideal pressure for the best balance of safety, handling, ride and fuel economy.
Use the manufacturer's recommended pressure. You'll usually find that on the
driver's side inside door post when you open the door. Check your owner's manual
What is more dangerous? Over inflation or under
inflation? Under inflation is a greater concern, especially on the
highway. The increased flex results in a heat build up inside the tire which
could potentially cause a blowout.
What about my spare? Don't forget the spare -
it can lose air slowly over time. Again, check your manual and/or doorpost to
determine the correct pressure. Most temporary spares require a higher pressure
than your regular tires. Also, safe vehicle speed and distance travelled can be
limited with the spare. These limitations may be on the tire/rim itself or
listed in your driver's manual.
How often should I rotate my tires? This will
depend on your vehicle and your driving style and the resulting type and degree
of wear and tear. Some rear wheel drive sports cars even come equipped with
tires of different sizes front and rear. Check with your T&T Honda service
advisor for his/her recommendations. The Maintenance Minder in your Honda (if so
equipped) also provides some guidelines for rotation under normal driving
How do I know when it is time to replace my
tires? There are a couple of ways to determine replacement time. The
information package that you received with you new car and/or tires specifies a
minimum safe tread depth in millimeters. Most tires also come with a wear
indicator. This is a small raised area within one of the groves of the tires.
Once the height of this projection matches the height of the tread, it's time to
change your tire. Uneven wear might also necessitate a tire change. Uneven wear
can also indicate over or under inflation or significant suspension problems, so
a regular visual inspection of your tires is
How often should I check my tires? A good rule
of thumb is once a month. However, if your car is behaving differently or you
are subjecting it to unusual conditions, you may want to pay a bit closer
What do all those numbers on the tires mean?
You may have seen something like this: P215/65R16 95H M+S. The P means that this
is a passenger car tire. The 215 refers to the width of the tire in millimeters.
The 65 is the aspect ratio - that is, how tall your tire is in relation to its
width. (In this example the tire sidewall is 65% of the width.) So, this number
will be lower on low profile tires. The R stands for radial. Virtually all
modern tires are radial. The 16 refers to rim diameter, in inches. The tire
width, aspect ratio and rim size are the key numbers to keep in mind when
ordering replacement tires. The 95 indicates the tire's load index, i.e. how
much weight each tire can support. The H is the speed rating. It tells you the
maximum speed the tire was designed to be driven on over an extended period. Of
course, posted speed limits and traffic and road conditions should also help you
determine the safe and legal speeds that you can travel at. M+S means that the
tire has at least some mud and snow capability. You may also see a
mountain/snowflake symbol; this tells you that the tire is dedicated snow tire.
Snow tires use different compounds and unique tread patterns. You can also
purchase summer/performance tires, but remember: these tires are not designed or
recommended for use in cold or icy conditions.
Do I really need winter tires or will my all-seasons
do the job? Think of all-seasons as three-season tires. All season tires
begin to harden up at about 7° Celsius. A snow tire remains flexible at much
colder temperatures. If temperatures drop to around freezing and lower each
winter and you regularly encounter some snow or ice, dedicated snow tires are
highly recommended. You'll stop significantly shorter on snow tires in cold
slippery conditions. We also recommend that you purchase winter rims. They'll
cost you a bit more upfront, but they'll pay for themselves in a few years, as
you'll avoid the cost of repeatedly removing and remounting and balancing the
tires on your originals. You'll also avoid subjecting your alloy wheels to the
hazards of winter driving.
Can I just put snows on the drive wheels? This
is not recommended. You may have the initial grip to take off from a stop but
uneven traction between the front and rear can create serious instability under
