Shop said don't replace based on depth

285/70/18 Ridge Grapplers 16/32 tread when new.

LF inner 9/32
LF outer 4/32

RF inner 10/32
RF outer 4/32

LR inner 9/32
LR outer 9/32

RR inner 10/32
RR outer 8/32

 

Your rears are fine but thats not good on the fronts. Something is wearing the outside fast. 2/32nd is a standard for replacement. With that said geographic location is big when dealing with low tread and rain or snow.

 

@Tundra234, check with @Ruggybuggy. He's an a old alignment guy that knows of an inherent problem with Tundra fronts wearing fast due to faulty camber settings. He can probably set you up with some revised numbers for camber.

 

Thanks. They did have about a year and a half of mileage on them with a Readylift spacer kit before I switched to coilovers and SPC's.

 

Time to get it on an alignment rack. Did you have an alignment done when you lifted?
