I have a 2025 Mazda CX5 and got new tires for 2 months. I switched 19” wheels to 17” and put new tires on them.

Other three tires are the same, but only rear passenger side shows different wear marks.

The line is about a quarter inch outside compare to other three.

Car goes straight and I don't feel any vibration.

Do I still need wheel alignment? (maybe camber adjustment)

I had an minor rear end accident slightly on that right side.

Body shop said that it wasn't enough for structural damage and they only replaced bumper.

What do you guys think?

 

This looks more like driving style? As well I would by using a known verified for accuracy (or a good quality) tire pressure gauge check all the tires early in the morning before the tires can get warmed up. But with new tires and making changes in tire size and brand tire it is only prudent that you get the alignment checked.

 

I see no difference. Neither tyre has worn out the mold release marks.

 

Yah I'm not seeing too much of a difference myself.

 

To help you understand, I've drawn some lines on tread wear indicators. I always measure the air pressure in the garage in the morning, so it's accurate. The line on the bottom edge of the tire is about a quarter inch outside than other three.
Thank you for all your advice.

 

As I suggested go get your alignment checked!

 

I'm with @Callisto on this. That would be a definitive answer.

 

Warranty adjustment period is 12 mos 12 k miles - take it to the dealer for free alignment

 

Make sure your new choice of tires and wheels are in specification for your Mazda or no it’s not a free alignment and they will enter the tire and wheel choices you are using on your VIN history which could effect your full Mazda warranty in the future having to do with other areas of your Mazda.

It may even stipulate in the details that the alignment is for the factory and or wheel and tire package when originally purchased. Best is to first contact the dealership and ask for the details first.

 

I'm finding it impossible to see tread wear on what looks like a new tyre. Your well off the marks with the comment abt tread wear indicarors.
