Is it an argument to a speeding ticket, that the size of your tires threw off your speedometer?

Probably not...

 

There's always a chance you might catch a break if you bring proof of speedo correction when you go to trial, though.

Is it an argument to a speeding ticket, that the size of your tires threw off your speedometer?

 

Nope....

it's funny, cause the officer was sitting on the side of the road, and when I past him my speedometer said 50. He wrote down 59 and said he took a few off . so im down for a 59 in a 45.

If your speedo said 50 when you were doing 59, you've got some serious issues with oversize tires. Why get them in such a huge size? You went like 3 sizes above what's normal for there to be that much error in the speedo at 50 on the peg.

That's why im so confused, cause supposedly it only takes 2 - 3 mph off, but he has me down for doing 59.

Best thing to do - get a lawyer and go to the traffic court - you can probably plea it down to unsafe driving which is 0 points... it is a little more expensive though.

Could have changed the rear end gear, transmission, speedo gear in the transmission, and/or tire size. My mustang speed is pretty much useless at this point considering all four of those items are not factory anymore. I just rely on the tach and GPS for my speed.

the reason it is not is because it is your job to maintain the workings of your vehicle.. but if you go to traffic court and plead not guilty as stated they will likely give you a more expensive non-points ticket..

Quota time! They'll tell you whatever speed, with a smirk on their face.

Which depending on your insurance company may cause your insurance to go up anyway. Check with your carrier before you pay a $450 ticket.

when it comes down to it, if you go to trial they will say "officer bob with 20 years on the force, impeccable record, blah blah says you were going 59". Your word vs his, guilty. Hope you take it to a shop and get your speedo calibrated, indicating it was off (before going to court for your trial).

 

That still doesn't change the fact that were speeding so says officer bob. You may have already incriminated yourself by talking to the officer while you stopped.

You have a right to see the radar display.

Id stick to lame questions about HV wires.

 

I highly doubt any cop would let a person into their cop car with a shotgun, mag lite, hand cuffs, laptop, taser, pepper spray, and who else knows what kind of sensitive items within reach. I don't remember seeing ANY law stating the police officer is required to show you the display. Then being sworn in is evidence enough that they are telling the truth. Besides, the police are trained to judge speed visually, and VERIFY with radar. In NJ they can issue a ticket solely based on that. Proving they were speeding is handled in the court room, not on the side of the road.

Chris,

 

How fast were you going? cut to the chase.

 

Were you going over 45?

 

In my z28, where you have to change the transition gear if you change the rear differential gearset, it will be off.

 

So on the 93 Z28's, that had the older 700r4, non electronic one... I went up to 3.73's in the rear, the speedo was off. it would read high.

 

tire size would not be that far off.

Is this how you're going to be?

 

I NEVER said that you "get in the car" to see the radar display. As for the other parts, I'll let one of the Leo's say yea or nay. I have been wrong before, unlike you.

There is no requirement to show the display.

Thanks.

After market programmers can re calculate your wheel size for the speedo.

depends if you have an electronic speedo or older manual gear one...

Sloop is correct.

 

Just as a means to compare, if you change from 29 to 33" diameter like I did and the speedometer reads 50 you are going 56.89 mph.

Use a GPS to verify your speed and note your tach at that speed. That can get you in the ballpark (if you have a tach), or just keep a GPS going for true speed.

If you happen to have an electronic speedometer, they make black boxes to correct them.

Just a couple ideas for future reference, sorry about your ticket.

I agree with the lawyer idea too. They would most likely request the radar unit's current calibration certificate.

GPS is great for speed when you have like your cruise control on. My mustang could probably hot 100mph before (at least my) GPS updates and says 50

 

Ehh... I take it off at the race track ever since my rear view mirror flew off and ended up in the back seat when I cut a 1.61 60ft

Jeez 1.61 60'.... best I've managed is a 2.0 60' but then again I'm only at 225WHP and FWD.

street tires

 

 

Lol... ok... Nitto drag radials but I drove em on the street. Line up, 5k, side step the clutch and HOLD ONNNN!

My 2.0 was with Drag Radials too... :\
