What would cause the speedometer to be off on a 96 Chevy S-10?
Different size tires and wheels. The factory size tires and wheels are calibrated with the speedometer. If a different sized tires or wheels are put on the vehicle, the speed can be off.
Why do you calibrate speedometer after bigger tires are installed?
You recalibrate it because bigger tires mean different speeds... for example, lets say your car had 14 inch tires... and your speedometer is saying that you are going 50, if you add 20 inch tires which is 6 inches bigger, you might be going around 60-70. No need to get a speeding ticket. Bigger tires cover more road then smaller tires, for example for ever 1 turn from a 20 inch tire is like 1 and ahalf turns from a 14 inch... Hope Ive helped you understand why :)
Do bigger tires effect the speedometer How do you calculate the difference I had 30 inch tires and now have 33 inch tires?
YesPutting larger diameter tires on any vehicle will affect the speedometer and odometer readings. If you know the revolutions per mile for the original tires and the larger tires, you could calculate the speed difference. If they are already on the vehicle, you can also drive down the highway, set the speed at 60 MPH and measure the time it takes to drive between mile markers. One mile at 60 MPH takes 60 seconds. If it is not 60 seconds between mile markers, the difference is the speedometer error. AnswerYour tires are 10% larger than the car thinks. Therefore, you travel 10% more than your car recognizes. This has two effects: Your actual speed is 10% MORE than what your speedometer is reflecting. (When your speedometer reads 60, you are actually traveling 66)10=11, 40=44, 100=110 etc.Your actual mileage is 10% MORE than what your odometer is reflecting. (When your odometer reads 100 miles, you have actually traveled 110)So when you see a cop doing a speed trap, remember to slow down accordingly.When you sell your car, don't forget to disclose that you have larger tires and that the odometer should read more miles than it does.
Do larger tires affect the odometer?
Yes. with larger tires the odometer will show less mileage than actually travelled.
Can you put Volvo 185 65r15 tires on your Honda accord that has 195 65r15?
Yes, you can put them on the car but I would advise against it. Install the wrong size tires and your speedometer and odometer will be off. Install exactly the size tires listed in the owner's manual and on the driver's door post.
Do bigger tires effect the speedometer How do you calculate the difference I had 29.5 inch tires and now have 33 inch tires?
Larger tires will affect the speedometer. There may not be a large difference in your application, but there will be a difference. You may be reading 45mph, and really be going 48mph. the worst problem will be in your odometer after a few thousand miles. your odometer will be WAY off once you have traveled a few K miles. I would suggest going to a local transmission shop to have your speedo re-calibrated for the larger tires. If you go much larger than that, check with your local mechanic on how well your transmission will be able to turn such a large tire. you may need to be re-geared.
Why does my Speedometer read faster than I am driving?
The size of tires can effect that accuracy of a speedometer. Larger tires will cause the speedometer to read less than you are actually going.
Will 2157016 tires fit 97 gran am?
If your car came equipped with 16" wheels they will fit, but the speedometer, & odometer will be off. The correct size tire for this vehicle is 205/55-16. That is what I would install.
Can you change to smaller tires on a Nissan Xterra?
That will mess up your speedometer and odometer. It will look like you are going faster than you are (not a real problem) and your miles will add up faster (a problem when you want to re-sell).
Can a tire 205x60x15 work on a car that uses 195x60x15?
Maybe, but the tire will be larger and cause incorrect speedometer and odometer readings. If the tires do still fit the car, some tire shops can recalibrate the speedometer. The size of the tires breaks down like this: P195 60R15 means a tire that is 195 mm wide, the sidewall height is 60% of the 195 (4.6 inches), and the wheel size is 15 inches. The diameter for that tire is 24.2 inches (15 inch wheel plus 4.6 inch sidewall (doubled because you have to account for both ends of the tire as you measure across) The 205 tire will be approximately half an inch taller overall (24.7 inches)
Can you replace a 225 65 R16 tire with a 215 60 R16 tire?
Yes, you can There will be about a 5% decrease in the tire diameter. 225 65 tires are 225mm wide and 146.25mm in height (65% of the width), while 215 60 tires are 129mm tall, which will affect the odometer and speedometer. When your speedometer reads 60 mph, you'll actually be traveling closer to 57 mph. Replacing the 225 65 tires with 215 70 tires would keep the diameter almost the same (150.5mm).
