You can swap out the speedo gear for the correct size for your tire size.
Quadratec & many other sites have them.

getting ticket excused

IF you have a lenient, and understanding, judge you might get it excused. What you will need to do is to beg off because you didn't realize that the larger tires caused the speedometer error. And, here is what happened. The original tires were 28" in diameter or 87.96" in circumference. The new tires are 33" in diameter or 103.67" in circumference`. That caused my speedometer to read low by 15.15%. So when I thought, and my speedometer told me, that I was going 55 mph, I was really going 15.15% faster or 63.333 mph.

Now the key is that the speed you WERE going has to be within the area of error caused by the larger tires. If not, you MIGHT still get that much of it excused and get the ticket reduced.

The other thing is you want to have the receipt, or such for the corrective gear to fix the problem and assure them that you will be able to trust your speedometer in the future and when you are staying within the speed limit you really are.

You see, math in school really is necessary and helpful.

You didn't say what the speed limit was and what you were doing.

Good Luck

You got a ticket for going too slow?
Or did you mean 40 in a 30?

If your court is anything like ours here in California you will most likely lose in court but if the officer doesn't show up or doesn't have a copy of the ticket it will be dismissed. Take it to court and if the officer shows up just say you didn't know the speedo was off and you admit to going 5 mph over

If it's anything like by me, you can plead to a no points ticket, like parking on the sidewalk, and pay a fine but no points; especially of you show that you rectified the problem.

Bring along a GPS sometime to at least know where your at. In my case, 50 on the dash is really 56mph.

Your speedometer is not the issue, you cannot beat their radar.
fix your speedo before you get another.

What year is your Jeep? (Electric or manual speedometer).
Superlift as a unit that adjusts your input to your speedometer, if you have a manual, you need to figure out which gear you need, I got lucky and replaced my tcase (had a noise) and the gear in the new tcase was right on with 4:10s and 33's.
