Just finished putting on new wheels and tires on my 2010 Sahara Unlimited. Went with 17" Pro Comp wheels with 35" Wrangler Duratrac.

Two questions:

1. Is my speedometer now off/inaccurate? If so, how do I correct it? Can the dealer do that?

2. Since I did not spend the extra $35 per wheel for the tire pressure sensors - the dam idiot light is on. How do I turn it off? I keep an eye on my tire PSI, so don't need it.

thanks for the help!

The answer to both of you problems is the AEV ProCal.

 

I think most states require a speedo calibration by law after larger tires. I use Superchips Flashpaq and think its pretty awsome.

 

your spedomator will start out at showing 2mph slower than your going at 30mph. And about 5mph slower at 60mph. Get a GPS to see.

 

Superchips will let you tune your engine thats pretty much the only difference than the price but they will both do the job

 

CA does not require it. The owner is responsible for driving properly here!

My speedo is off about 8 mph. I just pay attention when driving.
