i may be upgrading to 33" tires on 15" rims on my truck and will need to recalibrate my speedometer. what speedometer gear should i buy? do I just have to tell the retailer what size tires i have? or is there a specific gear? where can i buy them? I also need a gear for a 94 chevy pickup with 275/60/R15s on them. both trucks stock have 16"s on them. and on average, with stock tires, the diameter is about 30 to 31 inches.
94 chevy speedometer gear?
