very minimal and not noticeable. tires only have a quarter to a half inch in height difference.

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.

Yes. with larger tires the odometer will show less mileage than actually travelled.

If the snow tires have a bigger diameter than the others, the odo and the speedo will read a bit low. If the snow tires have a smaller diameter the odo and speedo will read a bit high.

TS = OR * CTD / STD Where: TS = True Speed OR = Odometer Reading CTD = Diameter of the current tires on your car STD = Diameter of the Standard Tire for your car.

An engine PTO runs off the engine thus the speed is governed by the speed of the engine. A ground PTO is ran from the rotation of the tires. Therefore the speed is governed by the speed of the rotation of the tires.

wrong size tires.

if the rear tires are turning the odometer does go up. but you can pull the drive shaft out and it will not matter the odometer will stay the same.

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.

Jet Accu Speed Speedometer calibrator. It adjusts your speedometer for bigger tires or gear change. Only works on automatic transmissions.

If the overall height is different, then yes.

difference between a/s and a/t tires

If you had 235 / 75 / 15 tires and switched to 235 / 60 / 15 tires : When your speedometer read 60 MPH you would actually be travelling at 54.2 MPH ( if that's what you are asking ? )

No. It will not effect speedometer accuracy.

the tires themselves.

yes by the same amout it throws off your speedo

theyre kinda the same but a speed brake is at a more vertical angle and are meant to slow the vehicle down. a spoiler is meant to put pressure on the rear tires to enhance traction and prevent spinning tires when shifting.

I have heard that at highway speed (75), you will be going ~ 2 MPH faster than it shows

what size is the original tires on a 1986 goldwing? what size is the original tires on a 1986 goldwing?

First off I am assuming the larger tires and wheels fit with adequate clearance. The 15" tires are likely taller than the 14" tires, that means they have a larger circumference, thus a longer rolling distance. It will make the car sit slightly higher. Most likely the biggest difference will be that the speedometer and odometer will read incorrectly, I don't know just how much.

The top speed maintained on an 05 outlander max was 105 KPH or 65 MPH on the original 25 inch tires and 100KPH on upgraded 26 inch tires or 62 MPH.The tire size could account for speedometer error.

If you change the size of the diameter of the original size of tire , YES If you go LARGER in diameter , you will actually be going FASTER then your speedometer indicates and If you go SMALLER in diameter , you will actually be going SLOWER than your speedometer indicates

Yes they are extrememly accurate as long as you are using the OEM size tires that came on the car from the factory and they have the correct air pressure as recommended by the manufacture. They are also not going to be as accurate with worn out tires as they are with new tires.

According to the world wide web light truck tires are not required by the Department of Transportation to have speed ratings. From this, I gather that there are not speed ratings yet but probably will be in the future.
