Lifted Subaru Tire Size Chart
We have been getting a lot of questions about what tire size one can run on their lifted Subaru lately so I compiled a list of verified tire sizes on different cars in the RalliTEK shop. We have 2 different columns, one is the standard size that we will tell anyone that they can run and then the other column is for an aggressive fitment.
The aggressive fitment column usually comes with the potential for minor trimming, cutting/flattening of a pinch weld, not being able to run front mud flaps or at the very least, using a heat gun to melt the inner fender out of the way of the tire.
Also be sure to notice that some of the tire sizes have an asterisk by them, this is because a 15” wheel is needed for that tire size and may not clear the brakes on your car. This list was created using either the 1.5” or 2” RalliTEK lift kit and Method wheels.
** This guide is just a reference, there are a lot of variables that can affect fitment. Please refer to you local wheel and tire dealer for confirmation. **
