    Looking to get a measurement of newish stock 20in 275/65/20 tires on a truck- in inches preferably! Going to battle with a hypertech inline speedo recalibrator and this would make it much easier on getting the settings right. Even bigger win if you have a topper + decked system and an aftermarket bumper + winch- wishful thinking! Thanks everyone!

    Manufacturers diameter won't work for you? Air pressure is going to make a diff on installed tires. Formula for a 275/60/20 = 275/25.4×.6x2 + 20" . This is general. Manufacturers diameters will vary somewhat.

    Nope, need it on the truck, on the ground for most accurate reading.

    Not going to get most accurate due to different manufacturers, PSI, weight, tread depth, Etc.

    Those tires aren’t much bigger than the stock 275/55/20 that come on it. Well at least compared to what most folks on here put on.

    i put 275/60/20 Michelin LTX defenders on my limited. It looks great and after having these tires go 70,000 on my 4runner I won’t put anything else on a mostly street truck.

    I’m rambling but honestly recalibration my speedometer is the last thing I’m thinking about. It can’t be off by a noticeable amount.

    I measured my 275/65/20 Cooper AT3 XLT @45 psi and it's measuring 33.25" with 7K miles on it. It's far less than the state 34.1" spec.
