17 inch gravel rally tire
Anybody know a vendor of such beast? I want to rallycross my street car (STI) and looking for some dirt shoes.

I've never heard of 17" Gravel tires/wheels. 15" is the way to go. Google the following: Speedline, Team Dynamics, and Compomotive. Once you have 15" gravels, rally tires this size are a dime a dozen.
OBShahn 03-12-2007 01:10 PM

None of the tire manufacturers that currently permit US market imports of rally tires make a 17" gravel tire.

17" gravel tires are made by a couple of different companies, but, you will have to find someone over seas willing to buy and then ship them to you (getting into the $1,000.00 range for a set of tires in all likelihood (although a top set of 15" tires will be about $600.00)).

There are some really good snow and mud tires that you can put on your stock STi wheels. Nokians and Normans are very popular choices. They are cheaper and readily available (and probably in a softer compound as well, so more grip but more wear).

I'll 2nd the advice to get 15" wheels, I have an RS so I can run OEM steelies. I bought a set (4) Michelin gravel tires for $60, they had been used for one stage rally and are in great shape

They sure won't. I believe STis need to run smaller rotors with 4-pot calipers like Racing Brake makes in the front and newer WRX 2-pots in the back.
Fred 03-12-2007 04:18 PM

Get a set of Avon Tech M550's in 225/45/17, if you want good rallyx tires to use on a stock STi. Stiff sidewall, good grip on dirt. And they're cheap!

Simplest way & probably cheapest to run 15" gravel wheels if you have an STi is to source some Subaru 4pot/2pot calipers/rotors.

'04 STi - Fronts will both right up. IIRC, R\rears will need an R180 adapter to fit the calipers to the knuckles.

'05+ - Call up Dan @ Fourstar and see if he can get any more 4pot/2pot set up's from rally cars that have been converted to bling bling AP brakes. That's what I did. I sold my Brembo's and essentially paid $400 for this type of set up. Mine were straight bolt on and will clear any rally wheel on the market. I'm not planning on running my car @ Rallycrosses but I wanted the ability to run 15" wheels during the winter.

There is a "local" guy here who rallycrosses on 17" Pirelli XR's. Not sure where he got them but gravel tyres in 17" are very hard to come by.

actually the 04 sti is a bolt on affair with the 4pot/2 pot - thebrakes off a (06+ tr)

its the 05+ thats harder due to the 5x114

There was a nice run of Pirelli 17" gravels in 2003 for SRT-USA for Pikes Peak, the last set I heard of were gobbled up sometime early 2005? If he got a set later thant that, I would imagine they are either used, had been sitting for a while, or very very expensive...
anickode 03-12-2007 06:04 PM

closest thing i can suggest is to find some 17 inch snow tires. they wont be AS good, but they'll definitely be better than street tires

Are you sure it's 100% bolt on in the rear? I've heard the rear knuckles are different with the R180 diff on the STi and R160 on the standard WRX.

Yes, the '05+ is harder...that's why I went the route I did. Mine was a complete bolt on affair. :D

Get the group N brake kit for the STI. You should be able to find it fairly readily, just not cheap.
Chromer 03-12-2007 07:27 PM

If there are any 16" wheels that will clear, Subesport sells 16" gravels... For around $190 a piece...

I want to say he spent near 1500 for those bad boys, but man are they nice!

Just get some snow tires and go have fun. If you start feeling the great need to be FTD (and you're consistently close to FTD on the snows) spend the $$$ to switch to the Group-N brakes and get some 15's. There's no point in wasting the $$$ on 17" rally tires. For the price of one set of the bling Pirelli 17" gravel tires you can buy a set of brakes, a set or two of Legacy 15" wheels and several sets of cast off rally tires from a team, or even a set or so of new tires from Hankook.

the Nokian WR is a [U]very[/U] good compromise.

How about getting some tough tires and have channels cut out of them? (siping?)
serg222 03-13-2007 10:08 PM

^^^^^^^yup^^^^^

That would be your most economical solution. You can get a grooving tool like the ones dirt track racers use. Here's one [URL]http://www.pegasusautoracing.com/productdetails.asp?RecId=1169[/URL]


And here's an article on tire grooving.

I was asking around of any 16's that would clear the Brembos and there apparently is some JDM wheel that will set you back some 900 bux a wheel. But as said above get some snow tires or just a set of all seasons that have good tread blocks. Most true gravel/rally tires are going to be on the 15" range with some in 16" so you'll be hard pressed to find 17's as when a rally car has those on they are doing a tarmac stage most likely.

people should be aware that doing the above to your tires will put you in the modified open classes (or whatever that class is called now).
Chromer 03-14-2007 09:50 PM

Modifying the tread will bump you to Prepared... At least in NER. But then so would rally tires.

Wow thread hi-jackers. I asked for a source for 17 gravel tires, not for your opinion of what I should do! (if you don't know me take that tongue in cheek)

So the short answer is nobody has a source for 17 gravel tires stateside? Does anybody know a european source?

Oh- and wassup Tree? Sittin' silly lately?

Find someone in England/Ireland that you trust.

I am pretty sure that Dunlop makes a 17" gravel tire, they'll cost about 100 pounds each, plus transport, you'll end up in the $1000.00 USD range in the end...
JD Ackley 03-15-2007 11:52 AM

Their are people in Ireland you can trust?:confused:

Dunlop huh? I'll keep on searching.

I bet there are some lads with Evos in the NYC area that know some people that could possibly help out.


As for Dunlop rally tires. They should be similiar in terms of quality to Hankook. They sponsor a couple of rally championships over seas, and I have seen results from various events with a variety of competitors putting up decent times at events with comparable fields to a US national. They aren't as spiffy as Yokohamas, BFGs, or Pirellis, but they should be pretty good.
