bigger tires, the right gear ratio vs. speedo gear

on my 93 yj, I installed 33x10.50's and removed the 307 gears and installed 4:11 gears. Now that should put me back to stock.Now finding a 34 tooth speedo gear is giving me the fits, but cruising down the road it seems like the correct speed. Shouldn't changing the ring and pinion to match the tire size put the speedometer back to stock speedometer reading? Why would you have to change the speedo gear? Now everyone set your beer down and think about this one.Can't use your opinion after the 24th beer.

If you changed the Gearing in the axles to the proper ratio for your tire size you wont need to change the speedo gear

What is the tooth count on the gear in there now? Tom's right if the stock tire and gear ratio is equivalent to the current tire and gear ratio the speedo shouldn't really change.
