New tire dealer had me rolling out with 50 PSI...?? - Toyota Yaris Forums

mirapatec · 10-12-2015, 01:36 PM

So, I just purchased a new set of treads for my Yaris. I was on the fence between Generals and Yokohamas. Finally decided on the Yokohama Avid ENVigors, and had them fitted.

Getting out and about on the roads for some test-driving, I noticed quite a bit of bouncing and overall harsh ride. I dropped back by the tire dealer to mention the tires rode a little more harshly than I had anticipated. Come to find out, they had the tires inflated to 50 PSI, which was somewhat odd for me to discover. They said the newer tires required more air pressure for longer life, handling, etc.

Anyway, I got home and lowered the air pressure to a more reasonable 33 PSI, as per the info inside the driver's door. I must say that the car handles much better, the ride is smoother, and it sure is quieter. However, I am now confused as to the deal with the 50 PSI.

Has anyone else had this situation occur before? Is this normal, or did I just get some odd-ball tire installer?

Sounds like they gave you a bullshit line to cover their arses.
It is not uncommon for an installer to over-inflate tires when mounting to get the bead set. However they should then drop the pressure down to the manufacturers spec for your vehicle. They didn't finish the job.

I can't imagine how stiff and punishing the ride would be with 50 psi. I do 35 psi on my Yaris, and that is about as stiff a ride as I want on 195/60 tires.

Plus, I was told that significantly higher psi on tires can strain the sidewalls excessively and potentially cause premature blowouts.
