35's and speedometer reading

[kevman65]

Can anyone running 35's give me a close idea what the speedo is going to be off?

Goofy me, figured I could wait until wheels got here to order a Tazer, and it's on back order.

I know it will be different at different speeds, I just want to avoid tickets in a couple of parts of town.

With the factory 33's on the speedo is within .25 MPH confirmed with GPS.

What can be done for Speedometer correction with 35 or 37's?

There are several programmers and an app.

I'm getting the Tazer Lite. Just waited too long to order it and now back ordered.

The app is JLScan I believe. You have to buy a few pieces of hardware, but I believe all in it's just over $100.

when you get the taxer, i needed programming of 34.44 for the 35's i ran and i'm on 37's now, they required 36.45 setting to equalize the speedo at 80 mph to gps speed

mine was a sport s, it came with a 32.24" setting even though my tires were rated at 31.5" tall, so it looks to me like they just put in the rubicon setting for the rated 32.8" (285's) that come on them...you could deduce a percentage difference from the numbers above if you had a calculator handy
