my new odometer reading

hey guys, just for fun i was wanting to figure out my new mpg with my bigger tires. what % would i add on the the tripometer to reflect the change going from 225x75r15 to 31x10.5r15? ive searched everywhere but the calculators online dont like going from metric to standard and back. thanks!

YOu need to convert the metric reading into a inches reading, and then you can figure it out from there

google tire calculator. its the one from the site 1010tires. works great to convert either size to metric or standard. that way you can use the calculators online without having to fuse with going from metric to standard back to metric like you was doing.

you need to change the gear in your t-case and then your speedometer and miles will read correctly. but till then:
