Ideal tire size for GD WRX sedan
About to install my coilovers but I am running 245/45/17s on my 17x8 +48 wheels and I’ve been told that the tires to run are either 245/40/17 , 235/40/17 , or 225/45/17s , I want to be 100% that I won’t rub which of those tire sizes would be ideal ? It’s most likely the 225s but I’d like a tiny bit more with and I’m in between 245/40 or 235/40 just wanted to pick your guys brains, I have a sedan by the way , 02 wrx

Will I not rub if I lower it ? I’m at stock ride height and rub occasionally in the rear , I’ve heard that 245/45/17 messes up gearing too since it’s too much tire , I can definitely feel the gearing aspect of it because it feels a lot more sluggish Sent from my iPhone using NASIOC |

I’d just like to have a one finger gap in between the fender at the top of the tire , and don’t want to have any rubbing issues. Right now I’m stock height and rub sometimes with the 245/45 so I’m guessing it’ll be worst when I get lowered Sent from my iPhone using NASIOC |

outer sidewall against the fender lip? fender liner on front wheels when turning? inner sidewall against strut/spring? on my VA, stock 17 size is 235/45/17 on a 8" wide wheel. Not sure what the GD size was, but there is a sticker inside the driver door that would tell you the stock size. The 225/45 will give you a slightly narrower tire and slightly shorter sidewall. Tire rack just covered a bunch of 17 inch wheels with 215, 225, and 245 tires on 7, 8, and 9 inch wide wheels. Very informative video.

I only rub in the rear strut / fender , not sure which one it is as it’s only when hitting a big bump , have a one finger gap from strut to sidewall of tire but I’m guessing it rubs on the lower strut mount plate . The front does not rub what do ever but it does have a 4 almost 5 finger gap in the front but turning side to side it doesn’t rub on strut . Wondering if it will change once coilovers installed or if it doesn’t rub now it won’t rub then. Picture show cases the tire to strut from the rear Sent from my iPhone using NASIOC |

coilovers will give you a lot more clearance inside. try one of those websites that compare one wheel/tire size to another and see the change.

So if I don’t rub inside right now I won’t rub inside with coilovers ? I used the wheel/tire size websites and after reading online found that the best tire size for the wrx is either 245/40 ( as it’s very close to stock diameter) 235/40 ( as it’s smaller than stock diameter which helps gearing on the 5 speed and gives a bit more torque) or 225/45/17 which is stock diameter. I did notice that the 245/45 does kill gearing as it’s a good bit bigger than stock diameter and makes the car feel sluggish which I can definitely feel right now Sent from my iPhone using NASIOC |

I am assuming when you say coilovers, it's the typical ones on the market. They are narrower in width compared to stock struts especially at the lower spring perch.

That is correct , aftermarket ones yes , fortune auto 500s to be exact . Thanks for clearing that up , just wanted to make sure that it wouldn’t be worst with the coilovers on . Cleared up my doubt Sent from my iPhone using NASIOC |

I'm kind of jealous of you sedan guys. Us wagon owners are more limited but coilovers help.

Is there a specific tire you are looking to use?
Reason i ask is that some tires run wide to very wide for their stated size, especially the auto cross tires. On a 17x8 wheel i would stick with a 235/40. Even on a 235 if you run an auto cross type tire you may have some rubbing going that low, but can probably fix it with a fender roll or more camber. |

Looking more for a summer tire , but if we are talking about brands Toyo Proxes sport in 235/40s because that’s the only company that has that size tirerack.com , possibly Michelin pilot sport 4s or falken Azenis FK510s Sent from my iPhone using NASIOC |

All 3 of those should be fine in 235. The Falken I believe is the widest. I only have personal experience with the Michelin, it's a good tire, but expensive.

I’d go with the Michelin pilot sport 4s if they have it in 235/40/17s which they don’t , if I end up going with 245/40s or 225/45 I will definitely go with the PS4s as they are available in those sizes , im starting to like the 245/40s as they are really close the stock diameter . Stock being 25” and 245/40 being 24.7” while the 235/40 is a bit smaller at 24.4” Sent from my iPhone using NASIOC |

I'm currently running the Michelin Pilot Sport 4s 245/40 on a 17x9 (Mach V Awesome). I've rolled the rear and still get a little rubbing on large bumps. I've only dropped it about .5 inches in the rear. I'm not running much camber in the rear so a little more camber should fix that. Your different wheel will change the profile of the tire a little so you may be okay with just rolling the rear, but most recommend a wider wheel to go with a 245.

You're missing the two main specs that determine rubbing. Wheel offset and if you have struts or coilovers.
Wheel offset is going to make a huge difference if you're running +35 or +53 like many OEM Subaru wheels. Coilovers open up the inside a bit by about an inch or so... which is huge in the rear. If you don't want to rub at all and have something like OEMish +53 offset wheels with struts, 225/45/17 always works. I know you can't fit a 245/40/17 with a +53. For street use, 225's are plenty. |
