OK, I did it!!! They are fantastic! Ride great, look great, I would absolutely never go back!!!

Thank you!

Any need for alignment? Considering doing this, but also want 18" or 19" for winter tires, and don't want to be doing an alignment every time I swap.

people will argue, but i'd do realignment when pulling or steering wheel off or its been a while, best practice

A seasonal alignment is a good thing to be doing!

Cool thread. I have adjusted my PSI to 39 on the screen - my oldish PSI reader says it’s 42 but will go with the screen.

When I picked up the MYP the screen said 42 and my reader said 45 and the ride was a tad stiff and loose. Basically I will play with it for a while.

I wonder if anyone has staggered the PSI to add traction to front. Like 39 in front and 41+ in the rear?

I am more used to using coilovers to adjust ride height (or springs) in order to make each corner carry the same weight - mostly with my prior German toys.

Not my area … but with the stock setup of my MYP (of 42) the ride can get a little loose in the mountains if the roads get bumpy.

I have read that this might be more of the breaks kicking in when the tires lose contact with the road - MYP vs Kia.

Who knows. Sorry for the lengthy post - too much coffee!

Cars don't magically lose alignment over the course of a year - you can have a car with excellent tire wear for 10 years if there aren't any major road hazards. Seasonal alignments are most definitely a waste of money. Once the car starts wearing out and bushings start to perish, then it's time.

I don't mess with cars that exhibit great tire wear, a tech is only bound to make it worse. If the car drives straight and tires are wearing evenly - there's nothing to be gained.

I have to roll my eyes when people hit a pothole and exclaim "Oh no! My alignment!". Your alignment did not just go out, unless you hit the pothole so hard it bent something in your suspension.
