tire size

[dan68anderson]

alright so I put larger tires on and adjusted it in the gryphon; the gryphon and speedometer is showing about 1-2 mph slower than my gps shows...would i increase the number that i put into the gryphon or decrease it? this whole math thing is killing me :shrug:

thanks for your help :2thumbs:

You'd increase the tire size, probably by about 2%. Take the number you are using now, multiply it by 0.02 and add that result to the value you are currently using.

jackandjanet, thank you for your help! I increased it by 2% this morning and it perfectly matched the mph my gps was showing
