What can I do to up the awesome on my crappy car?

Awwww yessss. Look at the beautiful speedometer and odometer.

Wait a minute, What did I just change Wait a minute, What did I just change? Let’s learn a little about these tires and the correlation to the speedometer.

P215/65R15 215 specifies the tire’s width in millimeters

P215/65R15 65 is the aspect ratio. It is the ratio of the height to the width. The height, in this case, is 65% of the width.

P215/65R15 15 is the diameter of the tire’s rim in inches.

Diameter of tire = sidewall height x 2 + wheel diameter A person decided to alter the appearance of his car by adding a lift kit, new suspension, & larger wheels. The original 1993 Chevrolet Caprice had P225/75R15 tires. The modified version had P305/30R26 tires. If the speedometer wasn’t recalibrated, how fast is the person actualIy going on the new tires when his speedometer shows 60 mph? Diameter of tire = sidewall height x 2 + wheel diameter Determine the diameter of the original tires. Determine the diameter of the new tires. 225(.75) x 2 x 0.04 + 15 = 28.5 in. Circumference = 28.5p = 89.5 in. 305(.30) x 2 x 0.04 + 26 = 33.3 in. Circumference = 33.3p = 104.6 in.

After one rotation of the wheel, how many inches further has the car with the larger tires traveled than the car with the factory-installed tires? 104.6 – 89.5 = 15.1 inches After one rotation of the wheel, the car with the larger tires has traveled how many times further? 1.2 (Work: 104.6/89.5) If the odometer reading is 89,000, what is the actual mileage with the larger tires? 106,800 miles (Work: 89,000 x 1.2)
