The BFG MT are known to be bigger than most, in that size at least. It's known as most others will fit on the rear carrier without modification but the BFG MT in that size has no chance.


My speedo is out at least 5%. So I'm doing at least 105 to 106 at 100 on the speedo.


For those discussing lock up. Mine still locks at the same speed on the speedo but a higher speed on the GPS. Just for those that thought it might be relaited to the high torque required for the higher gearing caused by the bigger wheels.

Does that mean when you're stopped....
