Initial Review, 770 Miles on Tires
April 13, 2012

I purchased Insight w/ CVT Automatic transmission 1 year ago. Car had 130K miles from the orig. owner & kept the car as close to new as you could hope to find. All service records since day one including tire purchases/alignments. Also detailed mileage log that included all gas fill ups, average MPG (46.9) for each tank, etc. Car had a new IMA battery installed 2 years ago and shows a full charge often. I commute 30K miles/year. Most driving is at speeds of 50 MPH or more on paved road. My drive includes freeway/highway roads w/ elevation changes of 900 from start to stop. 5-6K of these miles are city driving with lots of starts and stops. Not much rain and no mud, ice or snow. Over that past year I have averaged 46.2 MPG. If I "babied" the throttle & drove less than 60 MPH I could get 49.6 MPG. However, typically I would get in the 45-46 MPG. When I purchased the car it came with Dunlop tires since the owner had switched to this brand many years ago after the first set of original RE92s wore out @ 62K. I currently have 750 miles on the new replacement RE92s. First thing I noticed was that my mileage jumped up to 50 MPG in the first 100 miles. I then took the car in for an alignment and this was a good move as the car needed an alignment even though my old tires did not show any kind or abnormal wear & the car tracked strait when the steering wheels was not touched. After the alignment the mileage continued to improve. I have now driven 750 miles with the MPG keeping steady at 56.2 MPG. It should be noted that the MAX pressure on the tire says 44 PSI but I choose to run my tires at 50 PSI & had the car aligned with that tire pressure. A interesting outcome is that my road noise is now quieter with the new tires than the old Dunlops & when I go over bumps or rough sections of the road it is easier on me. My only complaint I have thus far is that the car seems to be more responsive to steering and will take time. It is not bothersome-just different.

Accutire Air GaugesIf your tires are going to provide the handling, traction and durability they are capable of, then maintaining proper air pressure is required.

Many drivers spend money on new springs or buy car battery, but forget about something as simple as periodically checking their tire’s air pressure. Adjusting the tire inflation pressure to the “right” inflation pressure helps ensure there are no sacrifices to your tire’s performance.

Remember, you can’t set tire pressure and then forget about it. Consider an air gauge from Accutire, as they accurately measure air pressure within +/- .5 psi and are easy to read.

Accutire air gauges are backed by a 5-year warranty and include lifetime lithium batteries.

Braille Lightweight Car Batteries

Braille Batteries Braille racing and automotive batteries were created to give the user enhanced performance from their electrical system, as well as enhancing the overall level of handling from the car by reducing the weight. 

When buying a car battery, one must take into account its intended usage. If your intended purpose is pure racing, and the battery is only used to keep the car's electrical6 lb. Braille Lightweight Car Battery system going throughout the competition, Braille makes the Lightweight Racing series to fill this need. From 6 lbs. to 21 lbs., they will save precious pounds from your competition vehicle. Some of the heavier models pack enough punch to use as a street battery in warmer weather. See technical specifications on each model.

If you are buying a car battery for year-round usage, Braille offers the Endurance series, which are hearty enough to use year-round. Utilizing the same clean, no corrosion technologies, the batteries gain weight over the racing series, but are still lighter than manyBraille Endurance Series Battery (Group 49) other traditional car batteries. They are a sealed-cell battery with sufficient power for year-round usage, and are made from environmentally friendly recycled materials.

Under Pressure: Pressure Gauge vs. Ambient Temperature

Monday, April 12, 2010 by Woody Rogers
Originally written for Grassroots Motorsports magazine late last year.

As we fine-tune our setups, we often make small tire pressure adjustments to help balance the car and manage tire wear. Small changes can make a difference, and the gap between winning and second place can be smaller still. So how accurate is your tire pressure gauge?

To find out how the various commercially available tire pressuregauges behave in real-world conditions, we tested several types against a calibrated, high-end digital unit. We used a tire and
wheel assembly initially set at 40 psi, and took multiple samples with each gauge. Readings were taken back to back with the reference gauge to minimize the influence of air loss after those multiple readings. The reference gauge and tire were kept in a climate-controlled room for consistency.

The Gauges
Reference This high-end digital gauge has been calibrated for 1/10 psi accuracy.
$50 0-60 psi dial gauge w/bleeder valve This gauge has been in service for several years, replacing one ruined by a single drop onto the pavement.
$18 low-cost digital gauge: We’ve used this one daily for nearly a year and have dropped and banged it a number of times.
$5 pocket digital gauge This one’s brand-new.
$1 pencil-style stick gauge: This gauge has led an unknown but lengthy service life.


Room Temperature (72 Degrees F)
Dial gauge 0.9 psi low, 2.26 percent error
Low-cost digital gauge 0.4 psi high, 0.98 percent error
Pocket digital gauge 6.4 psi high, 16.11 percent error
Pencil gauge 5.6 psi low, 14.18 percent error

The low-cost digital gauge proved to be consistent and accurate despite its hard
service life. The $50 dial gauge was also reasonably close, but it was off by more than
2 percent. Think all digital gauges are the same? The pocket digital gauge had a 6.4
psi error versus the reference—that’s 16 percent—along with a 2 psi variance in its
readings. And since most pencil gauges are known to be inaccurate, our example’s 6
psi error wasn’t much of a surprise.

Below Freezing (4.5 Degrees F)
Dial gauge 2.0 psi low, 5.13 percent error
Low-cost digital gauge not functioning, no reading
Pocket digital gauge not functioning, no reading
Pencil gauge 4.8 psi low, 12.37 percent error

Have you ever left your gauge in a glovebox or unheated garage during cold winter months? Just as tire pressures change with temperature, so can the readings on your mechanical gauge.
Why? Its pressure readings rely on a temperature-sensitive spring.

To measure the effects of a chilly environment on our gauges, we stuck them in the freezer for 18 hours. At subfreezing temperatures, the dial gauge read 2 psi—5 percent—lower than
the reference. Interestingly, the pencil gauge was slow to give its final reading, taking more than 2 seconds. Alarmingly, neither of the digital gauges worked. Their LED flashlights continued to
function, so we knew their internal batteries still had some power.

In the Sun (105 Degrees F)
Dial gauge 0.8 psi low, 2.06 percent error
Low-cost digital gauge 0.2 psi high, 0.52 percent error
Pocket digital gauge not functioning, no reading
Pencil gauge 1.5 psi low, 3.9 percent error

After giving the gauges 24 hours to return to room temperature, we placed them in the sun for several hours. We wanted to simulate a gauge left on the pit wall or tool box. The air temperature was 79 degrees F, but the gauges heated up to 105 degrees.


Our tire gauge tests taught us a few things, and helped us come up with some recommendations for gathering the best readings possible:
  1. Treat your tire pressure gauge like the precision instrument it is.
  2. Go digital. Even $20 will buy an accurate gauge; spending more adds features and may allow for recalibration, but probably won’t improve accuracy.
  3. Mechanical gauges are more prone to fluctuations in temperature. They can also be permanently damaged by even minor bangs and bumps.
  4. Always use the same pressure gauge. Different gauges are likely to give different readings. Using the same gauge will at least keep all of your readings relative.
  5. Have your gauge regularly checked for accuracy.
  6. If your gauge reads low, you are over-inflating your tires. If your gauge reads high, you are unknowingly under-inflating your tires.
And keep in mind: We conducted our test with our wheel and tire set to 40 psi. If your pressures are higher or lower, or if you’re using a different brand of gauge, your results are likely to be different. After all, even variance is variable.
