50k tire rotation

I'm almost at 50k and just got the maintenance notification on the MID after I rotated the tires.

I still haven't gotten around to adding the new tpms sensor I had to replace on one of the OEM wheels, but I'll get around to it one of these days.
I inspected the rear brakes, but I can't really see the inner pads so I'll be on that soon. The fronts have a bit of scorching on the rotors, but nothing I'm worried about yet. Besides I had to lockup the brakes a few nights ago while passing a labor day party with someone leaving - out from behind the line of cars on the side of the road

Anyways, I thought I noticed the front right tire looked more worn than the left.
I compared a couple of well traveled routes and noticed after the tire rotation that I'm not getting the same efficiency as I was before the tire rotation. And it's quite noticeable to me, not so much to the other daily driver.

My thought is that the right front is out. So I think it's time.
I'll be checking the tread depths as soon as I can get at the machine.

 

Thanks for the replies and apologies bout the confusion. Anyways, I need to take care of yearly service and I finally got around to step one of this series with the tire rotation and visual brake inspection. But like last years brake job I had to do most of it at night.
I replaced the OEM tires with Michelin Defenders just before I tackled the nackered front brakes at 36k miles last fall, referenced here
It was already starting to get dark when I started and it was night and had rained before I was done. Nothing wrong, just typical of my wonderful scheduling abilities ....

I actually got the first front wheel off the car before it got dark and looking down at the tread I was shocked at how much it looked like the right front tire had worn and my mind started working overtime trying to diagnose why.

I got my tread depth gauge out and measured both tires that were on the front, that are now on the back, last night. I only lost 3/32s in 14k miles, but I swear it looked like 6/32s of the original 11/32s. and on 90k mile tread life warranted tires. All 4 treads on both tires were within 1/64th of 8/32s (I did straight front to back wheel changes, but I'll be double checking the rotation marks to see if I screwed up when mounting the defenders last summer. thanks FuelMiser ).

I hope that reduces at least some of the confusion.

Concerning the brakes, again I swear &)(^%&)% looking through the mags I thought the rear rotors were rusting on about 1/3 the outter pad mating surfaces on both sides. When I got the wheels off the rear rotors and pads looked fine on the outside. But I couldn't really see much of the inside pad and non of the inside of the rotor yet. I want to get a look at how they've handled the first 50k miles (and fingers crossed) how the factory packed the slide pins to compare with what I found when I did the front brakes last year..

Than after I get those chores done I'll get around to the yearly oil change and reset the MID maintenance minder.
