RE: GEARS FOR DUMMIES
Here is the formula for determining new gears after putting on taller tires
(New Tire Height/Old Tire Height)*Current Gear
(33/31)*3.55=3.78
(35/31)*3.55=4.01
(37/31)*3.55=4.24
Lower gears(numerically higher) will increase the lower end umph
3.55 3.92 4.10 4.56
Remember you have to do BOTH front and real diffeerentials
245/70R17 30.50"
265/70R17 31.61"
275/60R20 32.99"
315/70/17 34.36"
