Default need tire size help

Have 09 wrx sedan. Lowered on RCE Yellows.

The wheels I'm going to be putting on are 18x8.5 et38

I've been told several different sizes will work.

245/40
235/40
225/40
245/35

Really don't want to have to roll the fenders, but if it's needed, will do it. Just have to find a place to do that first.


Any help would be appreciated.

I believe the stock wheel diameter is 25.3" (thats wheels and tires" so choose the tires that are closest to that. Tirerack has the outsude diameters for every tire they sell listed.

Keep in mind that if you get something thats a different diameter, your speedometer wont tell you the actual speed youre going at.

Also, are these all season or summer tires youre looking for? Don't recomend going wider than 235-240 with all season.

When you get the tires mounted have the car lowered and turn the wheels and check both sides to see if they will rub against anything. If the 245/35r18 touch see if you can go to 235/35r18 if you can.

If you go 245 you will have to roll the rear. I'd go 245-35-18 but my second choise would be 235-40-18.

If he has a rubbing issue, it most likely will be in the rear not the front.
