tire pressure - Toyota Yaris Forums

HerYarisNotMine · 03-01-2011, 05:20 PM

Higher pressures like that will result in stiffer sidewalls...that helps handling, but will cause premature wear on the center of your treads...also, your tires are part of your cushioning and suspension system, so if you make them stiffer, you are transferring shock to your suspension system, which increases wear on it.

Everything is a trade off. If you car is a toy, sure, do any mods you want to increase your pleasure in driving it. But if it's a daily driver, I would follow factory specs for tire pressure. The extra MPG you massage out of it imo isn't worth the reduced traction and additional wear to the suspension.
