Post 225/45/17 vs. 215/45/17

I just got my set of 17x7 Prodrive P1's in anthracite for my WRB wagon... woohoo!!!

Except one was missing a center cap, and now I have to deal with Prodrive because vividracing won't accept the responsibility.

Anyway, I'm deciding between 225/45/17 or 215/45/17 Pole Position S-03 tires. Currently, I'm riding stock height on my wagon, but I might consider adding Prodrive springs in the future... but no lower than that. Which tires would you guys recommend? What are the pros and cons to the different sizes?

Thanks,

Joe

Joe,

215/45-17 S-03
No issues w/clearance.
Significant upgrade from stock.
A bit shorter than stock (speedo will be slightly off, better gearing for autox).
Somewhat less expensive .


225/45-17 S-03
Will out-corner the 215's.
S-03's run wide, so you'll want to roll the fenders for clearance, if you lower your car.
stock diameter.
Somewhat more expensive.

That's about it....

I have a set of OZ Superleggea's in 17x7. I have been running 215/45-17 for about 6 months and 8,000 miles. I recently switched to 225/45-17 and you can really tell a difference especially in the corners. I was not dissapointed in the 215 and was actually expecting not that big of a difference in the two, but there is so the increase in cornering performance is wishful thinking. The ride noise and comfort is a lot better but that has more to do with the better tires than the size. I'm running Pirelli Zero Nero's and believe it or not I like these better than the
S-03s.

Any way thats my $.02

wat offset? Im using s03's 225/45/17's on my sedan with
50mm offset (SSR comps). since the sidewalls are so stiff,
the tire pulls steeering on uneven surfaces... (yes, my toe
is aligned)
considering that, you might want to go 215/45/17.

im getting a smaller diameter steeringwheel to compensate
forthat an get an even snappier turn-in response.

on sumitomo HTR+ tires, 225/45/17's were no problems
with 52mm offset.

Getting 215's won't change the tendancy of the S-03's to follow grooves/irregularities in the road. I have some 215's, and they do exactly the same thing. FWIW - the sidewalls on the S-03's are only middlin' stiff for high performance tires. In fact, they're considerably more supple than the Azenis or BFG KD.

And if it is a result of sidewall stiffness (which I'm not sure about) then 215/45s could be even worse as they have slightly shorter sidewalls than the 225/45s. I think the S-03s are just pretty notorious for this "tramlining".

You drive a different car. 225/45-17 normally fits without problems on a sedan, but it's much more problematic on a wagon (which the original poster was asking about).

I will post pics as soon as I get them installed. I've tried to keep my exterior mods fairly conservative and tasteful. Even though I love the look of gold P1's on blue rexes, I still think it makes the car look pretty flashy, and to a naive non-subaru enthusiast... even gaudy, perhaps.

I think the anthracite p1s are a nice compromise it that regard.

Oh, and it turns out the guys at vividracing ended up hooking me up... they got back to me and said they have an extra center cap to ship me.

And did I mention I got the set for $800. Not a bad deal.

I also have 17" x 7" OZ SLs (with 215/45/17 RE950s). I am on my second set of tires. When buying my second set (I had these wheels on my last WRX too) of tires, I was told that 225/45/17s would not fit properly unless a 7.5" rim was used. You say no issues? If not, I would love some 225s next.

225/45 17s will definitely work on 7" wide wheels. I've seen this setup on many cars. However it might be tight on a lowered wagon. The 7" wide wheels will make it a little closer to fitting but S-03s are a wide tire. Might want to check the thread dedicated to 225s on lowered wagons to see if anyone has run that or a similar combo.

I think you're right.

If I'm doing this properly....
215 x 0.45 = 96.75
225 x 0.45 = 101.25

And if the aspect ratio is an expressed percentage of the tire's width, that means the 215 series tire has 96.75mm-tall sidewalls, and the 225 series has sidewalls at 101.25mm. Is that right?


Here's what I find confusing. Subaru, overseas anyway, used 205/50-16 on their old cars, before moving up to 17" a couple years ago. A plus one should be 215/45-17, right? (Even though that's also a +1 for 205/55, which we got in the USA....) Subaru used that size on their cars, but then put 225/45-17 on the STi cars.

And that's the same size our STi will get, I think. Why on earth would they upgrade the width without dropping the sidewall to maybe a 40-series? Yes you get a wider tire, but you also get more sidewall flex. With the recent trend toward stiffness in the sidewall... that's weird!

Even more confusing because a +1 from 17" is usually like a 225/40-18 for 16" cars. But... if the 17"s are already using a 225-series, then.............


My brain hurts.

WRXURV8 if you go to bridgestone's web site they have a sweet chart that breaks down the min and max width of each size tire that will fit each size rims and how much it will change the speedometer by giving the tire diameter.

225/45/17 will fit form 7in to 8.5in and the diameter is 25.0in

stock: 205/55/16 has a diameter of 24.9in
215/45/17 has a diameter of 24.6in

There was a big thread on this awhile back, I believe started by omahasubaru. From that thread, it seemed that you would have no trouble with a 225 at stock height, and would likely only have trouble lowered if you were running an offset under 50 and Falken Azenis (which I think run very wide). And, those that did experience rubbing didn't seem to have major problems, it was just a touch here or there that was easily solved with a fender roll. From the info out of that I put 225s on P7s (52 offset) on my wagon and at stock height in all conditions I haven't heard a hint of rubbing. My tires are Goodyear F1 GS-D3s, and I have no idea if they run wide or narrow. Great tire by the way; never thought I'd own Goodyear's again for street tires, but these are quite something.

FWIW, Tirerack guarantees fitment of 225/45 tires on a wagon at stock or lowered height, so maybe your best route would be to get the springs on, order tires from the Tirerack, and see how you come out. If they rub, Tirerack should replace them with 215s and reimburse you for all the labor expenses. And we'll all learn from your experience! Just one thought.

FWIW, I'm running 225/45-17 Toyo T1-S's on Tarmacs (7.5, ET48). I'm lowered about 3/4" on STi Genome suspension. No rubbing whatsoever even when I am really wailing on the car.

The P7 has a great offset and brings the wheel closer to the inside of the fenderwell. So you will have less reason to roll your fenders than someone with a lower offset. With 215's you will have loads of clearance. I had 215's (yoko Intermediates) on my Tarmacs before the Toyo's and even with the ET48 I had loads of clearance.

If you want to run a 225 and are a little worried about clearance the toyo is a perfect tire because it runs a little narrower than the S03 but is a tremendous tire. Its quiet, and has fantastic traction wet and dry.

Oh, as far as 225/40-17 sizes go, I think one reason it was chosen is that there are few, if any, 225/40-17 tires available. 225/45-17 is more common.

You must have missed my last post. Vivid Racing did agree to send me a center cap. At first, they told me to contact Prodrive directly to "avoid the middle man," but they followed up when they found some extra ones lying around.

Thanks for the advice folks... I think I'm going to go with the 225/45/17, since I'll probably stick to stock height. I like to drive off-road too much to lower it, and the offset of the Prodrives are high enough, where it doesn't seem like rubbing will be an issue. I'll post pics as soon as I can.

Hi Greg, how you been? I'm liking the toyo's. As I mentioned before I was running AVS Intermediates in 215/45-17. Despite being an old design those are still one of my old timer favorites. The Toyo's in comparison are just as sticky in the dry and feel a bit more progressive at the limit. They talk to you more in sound as well as feel. One thing though, is that initial turn in felt softer and not as crisp a the the yokohama tire. I think the sidewall is a bit softer but they are also taller in the 225/45-17, so that probably contributes. No tramlining whatsoever. Very smooth riding and pretty quiet. Not as quiet and smooth as the P-Zero Rosso I had on my RS but pretty good considering the tread looks like a truck tire! Its supposed to rain this weekend so maybe I can finally see what the wet traction is like. Plus they have a 280 treadwear rating so hopefully these will last a bit longer than the Intermediates. They are a narrower 225 but they fill the 7.5" rim very well. I can mail you a pic of them mounted on the Tarmacs if want, just post or pm me your email address.

I ended up getting Yokohama ES-100s in 225/45/17, and for the price, they can't be beat.

here are some pics of my new setup

They listed the set for $800 under the vendor for-sale forum. I was lucky enough to be the first to respond, but they screwed me over with a missing center cap. If you look carefully in the side photo I posted, you can see the temporary gold center cap on my rear right wheel, until I get a replacement.
