[QUOTE="Feral, post: 433816, member: 19535"] How much is the speedometer off since the tire change? I just switched from 30"s to 33"s and my speedometer is off 8-10 mph. This shows how much my final gear ratio has changed. I have 4.10 gears, so it actually made it drive better, but if i had the stock 3.73, I would be struggling to accelerate. I just ordered a 33 tooth speedometer gear [/QUOTE]
