Too much math needed for this one.My new truck has 10r22.5 tires and I have brand new 11r22.5 drive and steer off my old truck
What mph difference is my speedo going to show , the dealer wants 350.00 to recalibrate it which I think is typical dealer bull crap
I'm pretty sure I can adjust my brain to it!
I havnt found a calculator that does large size tires, maybe you know of a specific one
I have one just wanted to keep the miles on the speedo accurate ! I don't think it's gonna be that much of a difference anyways it's only 120 less revolutions an hr driving 60 mphGet a GPS and use the speedo on that instead.
Yes, the miata.net tire size calculator. Ive used it many times.I don't know of a specific one. I used to use one on a Miata website but it takes Flash or something I don't have so I can't check it. I thought it did all sizes but maybe not.
