Ok, I upgraded my tires to 33" on my 2000 TJ. What do I need to adjust and correct my speedometer?

ill tell ya wat. even better if ur by the jeep go look at the reear differential cover. there should be a metal tag on it at the 9 or 3 o clock position. it states what ur gear ratio is. should be a number like 3.73 or 4.10

Determine your axle ratio and look at one of the many speedo gear charts on the interwebz to determine the new speedometer gear tooth count.

Search "Jeep Speedometer Gear" on the web and you will find a lot.
