Hey everyone,
Looking to see if there is anyone out there that has 22.5 alcoas and their abs light on? I've got a 2006 f350 crew cab dually and the abs light was on when I bought the truck. Did some research and initially found that the tuner(sct x3) can adjust for wheel size. Then I read also that it can not.

I put in a call to the tuner to see if the revs/mile were adjusted in the tune that my truck has and he said it looked like it was matched to a 33" tire. The alcoas end up around a 37" setup. The tuner is going to adjust the revs/mile since that will help with shift points anyway. Does anyone know for certain if this calibration will help the abs light situation? I need to get an inspection and I have read differing opinions on if it'll pass or not with the abs light on.

Thanks!

 

Without having the codes read for the abs system you are shooting in the dark. Unless you had one tire substantially different diameter than the other three the tire size should not set an abs light. The abs system looks for inconsistancy between wheels. Have the codes read and you will know where to look.

 

Same size tires front and rear?

If so, then adjusting the tire size won't change the ABS warning light.

As suggested, find out what code it is, may be a sensor.

 

Yea the tires are all the same size. I'm having the abs code read on Friday so I guess I'll see what's going on then.

 

Putting 22.5 inch Alcoas on the truck will not cause an ABS light. There are other issues with your truck that need to be addressed.
