Hi there,

New to the forum. Recently downsized from a Tacoma to a Subaru. I’ve tried looking through the threads, but can find a simple answer. What performance impacts have people seen after bigger tires/lift on the 2.5i drive train? My fiancé and I often take trips to the mountains here in SoCal so I’d hate to sacrifice performance. Just curious on everyone’s experience.

Thanks!

I myself have experienced the performance robbing effects of bigger heavier tires on cars with small engines, and the benefits of lighter wheels and tires on a car with a small engine.

This article is a good one but it's not gospel - do whatever you want but he shows his logic and you can draw your own conclusions:

Yup. Thanks for the reply @SilverOnyx! Definitely answered my questions and prompted me to head down the rabbit hole for this topic. End result...MR 502’s with 235/65/17. Better tire than stock and not adding a significant amount of weight.

To add some anecdotal evidence:

My 2010 3.6R has a very noticable performance loss with my winter steelies, same size tire and rim as my aluminum summers but with a decent weight penalty.

Subjectively this is really noticed on acceleration and even fuel mileage (albeit other factors such as winter gas factor in on that). The 3.6 is by no means a small engine and it is still very noticable, I don't want to know what it would do to the 2.5.
