Is This Tire Wear Normal?

[Joseph Garcia]

What are your typical inflation pressures?

I had a similar issue when I got new tires on my 2017. The front outer edges wore more quickly than what I expected. I took it for service and said I want the truck set to the middle of the green range (it's quite a range of "acceptable " specs). I can see where they moved the adjusters quite a bit.

It tracks nice and straight kow with a change in the steering effort for turns, but always wants to straighten back out and track straight. I'll see how it wears over the summer. You may want to have them recheck the alignment and explain the tire wear. There is a way to set up a vehicle for optimum tire life.

Too many times a tech doing alignments will set the toe and let it go. As @B-train said, these guys/girls will just adjust enough to get in the green range and that is "good enough". You want them even, side to side, and close to center of the green ranges. I do like a slight caster lead on the passenger side, to help allow for road crown.

I would say yes.

This is the alignment sheet back from December. I dropped by the alignment shop about 8:30 this morning. I was told everything was perfectly normal because they are steer tires and that the alignment is perfect because it is in spec "as can be seen on the sheet." He mentioned that if the alignment was off that the outside tread block would be experiencing wear throughout rather than on the very edge like I showed.

I was hoping that they'd put it on the alignment rack as a courtesy to check, but obviously they are too busy and overworked and unenthusiastic to do so. So much for that.

He also said that I need to keep up on tire rotations every 6,000 miles otherwise I'd blow through tires in 25,000 miles. That doesn't exactly sound right to me, but I informed him that at about only 4,700 miles I wasn't even at the need for a first rotation yet either.

I try to rotate mine every other oil change.

The left front tire in the pic shows the scrub on outer edge and the alignment "after" shows the driver's side/left front tire is toed in more than the right front tire. The toe in is more on the driver's side.

I would say my left and right front tires are nearly identical however.

The alignment readings show more toe in on the left front tire. I see the scrub on the outer edge of the left front tire. I see no scrub on the right front tire.

It is there as that siping that is on the outer edge of the outer tread blocks typically carries through to the sidewall. You can see that on both front tires this small sipe is "disconnected"

What is conversely strange is that, to the opposite, those tiny horizontal nipples/fingers are present on the driver front tire but they are all disappeared on the passenger front tire. It is possible that I routinely make more right turns than left turns.
