Need help finding correct Speedo Gear.

I have a 1999 Jeep Wrangler with 4.56 Gears and BFG 32" Tires. When I use the chart to find the right Tooth Numbered Speedo Gear, do I use the physical measurement or just the MFG Tire Size. When I measure them they're around 30" in diameter. When I look that up it shows a 43 Tooth, is that right? What should I purchase? Also, is there a place online to purchase it?

here is a good chart to use...

Most people go by the MFG size but I've had better luck going with the Actual diameter. If you keep the 32's that you have I'd run a 42 tooth.
You can order these all over the internet/// 4WD, quadatrac, 4wheelparts, and so on.

But it is easier and faster to just pick one up at the Dealership. They can get them and usually at the same price or better due to no shipping cost as the online places.

And welcome to WF!

You can't beat the dealer's price on that part. I don't like that chart; with 4.56/33s, I'm using pt# 52067636 and it was good. I'm off a little now with 35's
