You tin search for "speedometer driven gear" once you have your VIN plugged in. You also demand to know the stock tire size and gearing so that you tin can summate the alter in ratio based on your new tire size and gearing. I believe if you have to stay with whatever "mark" you have stock. If your speedo reads fast, that means your current speedo gear is also small and is spinning to fast. You need to replace information technology will a larger gear. If your speedo reads dull, that ways your electric current speedo gear is too large and spinning also slow. You need to replace it with a smaller gear. shawnster88 Well-Known Member Joined: Aug xix, 2012 Member: #85096 Messages: 331 Gender: Male person Beginning Name: Shawn Panhandle Florida Vehicle: 96 Tacoma Reg cab 2.7 v speed OME 881 ringlet springs, OME nitrocharger sport shocks front and rear.

your speedometer is off considering of your bigger tires (and maybe the regearing itself) use the tire size calculator and do some experiments: https://www.tacomaworld.com/tirecalc

Excellent! Thanks. I'll take a look through these. Yeah it is a mechanically driven Speedo with 4wd.

You tin either summate information technology past using exact gear ratio to tire size changes, or more just by using the speedo gear and mph. The gears and tires volition probably exist more accurate, but you only have a couple options to choose from as far every bit speedo gears go. one - (lx/65) =~viii% therefore you need a speedo gear that is ~8% larger. one - (30/33) =~9% is probably as shut as you're going to become.
