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?

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.
What is the difference in engine pto and ground pto?
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.
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.
What makes the odometer go to fast?

What is the speed difference from size 75 tires to size 60 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 ? )
