Going up to the 55 profile at that width will add 20.5mm (.8") to diameter and 10.25mm (.4") to vehicle height. If maintaining cornering performance is not the goal, this raise should be fine. My winter tires raise my car slightly more than this. If it is a permanent change, an alignment would be in order after the switch........

 

Thanks for the detailed answer!

Yeah it would be permanent til my grandson gets the car.
Deff would have a alignment done.

Cheers!

 

EDIT: sorry, had that backwards initially. I misread that you were going UP in size.
Don't forget your speedometer will read slightly slower than your actual speed.

 

Yeah,,will check to see how far off with gps...prolly not much.
31's on my explorer threw it off by 6% though.

 

Well it seems there are not many tire choices at Tire Rack for the 205-55-17..but there are a lot of choices for 215-55-17.

Would the 215-55-17 still be ok?

The car for the next year or 2 would mostly just be a cruiser ..no high speed cornering or anything like that..but I'm looking for a little smoother ride that higher sidewall tires seem to give.


Here is what I'm thinking..I like the price!

Oh the car might see a little winter driving if one of are other cars might be down.

EDIT: Would 215-50-17 be a better choice?

Here's a quick calculator if you want to see the differences:

Thanks!
Real handy!

I think I would be fine with the 215-55-17

1.2" overall but cut that in half for clearance..seems like still plenty of room!
Thanks again guys!
I guess the tire choice is suitable it seems.
Good reviews for wet/dry/handling and some snow.

 

Is this a 2008 WRX we're talking? That's what mine had: 205/50/17.
I ended up upsizing the wheels to 17x8 and getting 225/45/17.
You can get away with 215 on the stock wheels though.

 

Yeah it's a 2008. Good catch!
Good to hear all would be good on my stock rims..thanks!

The car is really handling nice now that I put the moog end links and energy bushings in the front sway bar...both you can grease.
It really did make a huge diff. I thought my struts were bad but after what i did the wishy washy feeling is gone!
I just bought it a few weeks ago.

 

Just noticed that tire comparison deal also shows the speed change!
Only 2.9 higher at 60 with the taller tires.

 

So did you change the struts or just put the pinks in and the pinks lowered it?

Been reading alot and it seems the koni inserts are a good way to go...if I did that with the pinks would it stay close to stock height?

I was thinking about rce blacks or the king springs but if the pinks are really good and keep it clost to stock height I might go that way in the future if they need to be changed out.
That all said the grandson would not mind some drop..lol.


EDIT: I clicked on the link and now see that the pinks lower it some..not bad though..price seems good for a subie part!

They're a little pricey admittedly. I did nothing else except change to lighter/wider wheels and it made a fantastic difference.

 

I hope I can post this here but sinse you have a 08 what do you see for boost?

I have a scangauge II and I don't know if it's acurate but the most i see is 7 lbs.

Cruising at 65 it's showing -2.

The car seems fast enough ..I only ran it up to 100 once and it got there pretty quick and I know it has a lot more left.

Runs,shifts, and idles great..no complaints there.
I even got 30 mpg on a 120 mile trip..mostly all open x-way...5 or 6 stops altogether.
Car stops great also compared to other subies I have had.

It has 133k on it but the HG'S,water pump,timing belts were all done at 100k with the clutch.

I believe the stock peak was 11.x (wanna say 11.6?). I had my protuned for a daily driver friendly 16.9 peak. (stage 1+ / 191 WHP & 260 WTQ) It handled it just fine and made a huge difference...took away a lot of the lag and gave me much better off the line acceleration. I managed 31MPG once on a road trip from Michigan to Alabama AFTER my tune.

 

I also forgot to mention new turbo at 100k also.
If it would have been me i would have had them put one on for a 09. I doubt they did.

 

Here's my album if you want to look so you can see with the pink springs how it sits...and the aftermarket wheels. All subtle mods.

Nice I see you put a bug/stone scren it the scoop..looks good and I like the rims!
Nice stance also!
Mines a sedan and for me I like the looks of it.

 

I don't know if it's true or not but one guy said that snow can pile up there with a screen..dunno.
But yeah those rims look good!

Mines red.

 

 

I did order these from tire rack two days ago and they are already here!
Looking good! Prolly won't get them on till this weekend.

I have had a few cars back in the night-68 roadrunner,70 challenger and what not and this thing makes me smile just has much!
Really smile when I check the mpg compared to my old rides!
slow 08 my butt! lol

 

Tires are on and I really like them...pics tomorrow!
