Wheel Speed Sensor Tire size drama

[Celigts]

Greetings,

Been running some
255/35/18 fronts
285/40/18 rears

8% difference.

My Wheel Speed Sensor (WSS) has been lighting my dash up like a Christmas tree on and off for months.
Several dash lights including traction control/abs/check engine/speedometer(not working)/no cruise control(lights up yellow vs green if attempted to use)/power steering/power loss(can't rev past 4k)
All of this goes away once you turn the car off/back on.

So needless to say ... It's fun...

I was looking for some CONFIRMED different wheel size setups that are NOT triggering this issue ...

I've been looking into replacing my 285/40/18 rears with 285/35/18
this would give me a 3.6% difference.

Anyone running 3.6% difference or higher w/o this issue?

If you're unsure of how to calculate the Wheel size diameter difference...simply post your wheel sizes and I'll check the calculator for you.
or visit this website and plug in your sizes

Greatly appreciate any help! Thanks!
