ok so i think i got this right
for old tire size i typed in 275/65-20 (i believe thats the stock size, havent looked) that came out to old diameter 33.37" ( 847 mm ) old circumference 104.83" ( 2662 mm ) old R/mile 604 for the new tire size 285/75-18 which came out to new diameter 33.98" ( 863 mm ) new circumference 106.75" ( 2711 mm ) new R/mile 594 with a 5% squish on 3.73 gear ratio the effective ratio is 3.66 with a new ratio of 3.79 so i should put 2711mm for the custom options, should i change the gear ratio? or leave it at 3.73?? how will i know i am going faster than 60mph? i have mph as an option on the gryphon but i will not be able to have a police radar me or anything
