Hello!
I was reading through an old thread about 5 tire rotation, which I'm definitely going to be doing myself. My concern is this:
I bought my truck used with about 11k miles on it, so I'm not sure of the tire rotation history. I took some measurements and got the following:
- Front: 10-10.5mm
- Rear: 11mm
- Spare: 12mm
I thought on a RWD vehicle the rears would wear more? Or am I mistaken and front wears more regardless due to steering friction? I was going to follow the pattern shown here (credit to
@dover157 from the other thread)

but I'm concerned that they may have already done a 4 tire rotation at the dealership. Can anybody clarify what I should be expecting if there was never a rotation done?
Thanks y'all
