Back when I thought I had to have big tires on my 4 X 4 truck to go anywhere, I learned that the taller one goes, the more it throws off your speedometer, odometer. If a guy has 25 inch stock tires and goes to 27's or something like that, does it effect the digital unit accuracy? I'm staying with 25's to prevent power loss but was just wondering about this. Thanks for your time.

Yes, you will read a couple MPH slower than actual if you go to a 27" tire.

Most likely if you are reading 42 on the dash with 25's if you go 27's you may only read 39-40 but actually be running the same 42 top speed due to the gearing change.

Well I found that 27inch tires brought my speeometer closer to right. I have GPS on my Rhino and has speed on it which if very accurate. My speedometer was off by about 4 mph before, with 27inch bighorns is is 1 mph off. go figure...
