Did you check the tire pressure again after the tires were installed?

 

Yup currently all at 32. But they are filled with air and not nitrogen. I live in Minnesota, and we do know how to have winter (dont look at last one) with snow and cold, and we do know how to do summer. So I may see if Lexus can fill them with nito if folks think thats a good thing.

 

32 is still going to have an effect on ride, if you want the best ride air them to the factory reccomendation pressure, 30. Remember pressure rises as the tires get hot..

Don't bother with the nitrogen...

 

In the past I never paid much attention to nitrogen in tires. My 2010 came with it and the biggest benefit I've seen is how the tires hold their pressure through temperature changes both up and down. I don't have to add air like I did in the past.

I wouldn't pay to have it put in my tires but since it's there, I like it.
