Nope nope nope. Uhh I'll change what I said if its confusing.
Never will your axle sping at a different speed as your tires. It is physically attached to your tires with bolts, and will spin at the exact same speed. When you put bigger tires on a truck, it takes less revolution of the tire to go the same distance as your smaller tire. So if one person driving 29 inch tires drives for *1 mile of distance on his speedo* and a person with 33 inch tires drives *1 mile of distance on his speedo* the guy with 33s will be some distance farther. Therefore, if you have larger than stock tires, your speedometer will be under a few miles per hour.
Sorry, I don't know what I was thinking when i said the axle and tires rotate at a different speed, they're exactly the same, and if they're going diff speeds, you broke some **** badly!
