You can use the speedo gear calculator on the moparts tech department. You can give in your own data, and it will tell how many teeth you need on the speedo. But I think it's around 33 teeth.

my chart only goes up to 235-60-15, which shows 32 teeth or black. As the tire size increases the teeth decrease, so it may even be a 31 or green. Please note the colors are used with more than 1 tooth amount, so you should still count or look, most of the time the tooth count is cast into the plastic.

There is a chart on mymopar that gives you the information you're looking for.
You will need the tire height, which can be found on Tire Rack.com. According to that chart you would need 32 teeth.

Any Chrysler dealer should have them for about $15.00 thats where I got mine.
