Re: The 32.5" BFG M/T KM's & Truxxx Fit Great!!!
How is that possible that you are going slower than your speedometer with tires that are considerable larger than stock? I mean, it just does not compute. I believe you, but it does not make sense how that could happen.
For every one turn that the wheel sees, it is registering the distance travelled as the circumference (3.14 * 29.5 = 92.67 in.) of your factory tires. Your circumference (3.14 * 32) is larger than that by 8.4%, so at 60mph on you speedo you should be doing roughly 65 mph in reality. My error with 31.4" tires is about +7.5% as measured by two different GPS systems. You should have to get smaller than factory tires to accomplish what you have reported here.
Was your speedo dead on before the tire swap?
