2011 KK with the Select TracII system. For those of you who have gone to a larger diameter tire size, has this caused any problems with the traction control/ABS/Stability control? Or has the CPU simply learned to deal with the change? |

My turns on for a second on those slow right or left turns when I leave my street. No big issue it is from my tire rubbing on some plastic |

How's that thing drive with those tires on it. Does it feel underpowered? I've been thinking of doing the same thing but I'm not ready to regear yet. |

How's that thing drive with those tires on it. Does it feel underpowered? I've been thinking of doing the same thing but I'm not ready to regear yet. The loss of power is very minor. I planned on getting regeared as what I heard, but I have not regeared. It has enough power on the city streets no issues, on the highway around 65 to floor it makes no different than giving it enough pick up enough speed as I need, it is not a hot rod. I tow sometimes 2000# & this is where I start to see some power loss up very steep hills. It can hold 55mph up the hill with ac on and be 115 outside. The issue with towing is finding the right rpms as trying to go 65mph up steep hills is in between 3500rmps and 5500rmp which you can get to When towing up a steep hill so you are stuck at 55mph unless you want to push 5500rpms which is not good to hold that long! |

When I had my FJ Cruiser I lifted it about 2.5" and kept stock tires for a little while but toyotas have the same issue. I went to the dealer after reading some posts on their forums and the dealership does a recalibration of the speed sensors, I believe. Found one of my own posts and its called a ZERO POINT CALIBRATION. Idk if anyone has it in good with a tech but they might see if this is possible. I know just about anyone with a lifted FJC has the same issues with these newer trucks with computers galore, any amount of unalignment while the battery is unplugged can cause this. |
