I'm going to rub in a few days

Guys I bought the tires because I need a wider foot print. I've been told by a lot of people these are very good tires for our car but with me going to be pushing close to 400 hp and already slipping at 280 I needed a solution to traction. Firehawks only come in 215/45r17 unless I went down to 205 and then it's stock size.

Maybe a limited slip differential could solve all your grip issues. Might be exactly what you didn't know you needed. As for the tire rub in the wheel well might have to just accept it if your like me and didn't buy coilovers for stock ride height. #HardParkDreams

Okay I see your point but, I took the word of other people from their experience. Thing is, treadwear ratings are set by manufacturers and then reported to nhtsa. So it's kind of bs anyways.

True, to a point.
But when it comes to 100/200 tread wear rated gumballs, they are almost exclusively MUCH MUCH stickier (and yes, MUCH shorter lived, but you must PAY for traction, one way or another!) than ANY 280 to 340 and above tread wear donuts.

The only exception I've ever heard to this is the 300 tread wear Michelin Pilot Super Sports/4ses, which most claim stick like a 200 tread wear, but wear like a 400.
Sadly, Michelin was NOT kind enough to produce them in ANY size WE could use. [:(] [mad]

I doubt any of those people are 400hp -you have to look at your use case. you got a tire that is great for driving to work and hitting a couple back roads with 250whp or so. that's not exactly what you are up to. you need something like a hancook RS4, bridgestone re71r and similar that are overrated at 200 and probably more like 150.
You'll be fine on those tires, but after what you just spent on a turbo and a fuel system is a little ashame to get a return on all that money because you can't put the power down.

@M-Sport fan I do love that 4ses, have those on my vette.

Im running the 615s. Pretty good for the money. Be careful in the wet. They do a bit better than the re50 but not miles above.

I should have phrased that as "any size which is NOT more than a three quarters of an inch taller than OEM". [wink] [:(]

In a 17" wheel, at this point, I want something that is MUCH wider than a mid 7" wide tread width as well.

I'd go nankang ar-1 215/40/17 on a 17x8 wheel for track use.

For daily, I go with the mpsp 205/45/17 on a 7.5 wide rim. it would give a contact patch of 7.2

Alternative with a 17x7.5 or 17x8 for street tire, I'd go pzero Rosso 215/40/17.

You can fit a 18x8 td pro race 1.2 with pilot supersport 225/35/18, that would be cool to try.

Tire choices suck for the fist

Yes, the tire choices (or complete lack thereof) DO suck for these cars! [mad]

The WRC tarmac spec cars use an 18x8 wheel to clear huge tarmac spec brakes, but they don't have to use rubber band profile tarmac tires, since they have plenty of room in those big box flared fenders, as well as much suspension travel and clearance to use a very tall setup.

They are also using magnesium wheels, so the weight of these huge wheel/tire setups does not become that much of a penalty either. [wink]

That 225/35-18 setup would be cool, but that super expen$ive, 'rim right on the ground', super rubber band profile setup would NOT last too long on the roads around here, and I suspect, in your locale as well.

Seems like A LOT of bother/risk/expense just to be able to use (the excellent, yes) Pilot Super Sports, no??

I agree, the 18's with tires would be about the same as a wavetrack lsd and install.

We already have wheels and tires, we don't have a lsd. Enough said

EXACTLY, the manufacturers of these things just effing assume that everyone/anyone buying these things ALL just want to slam their rides down onto their tires, like bagged stancers. [mad]

Vendors/manufacturers; WE NEED MORE COIL OVER OPTIONS WHICH ALLOW FOR FACTORY RIDE HEIGHT(or even a bit higher) AS A POSSIBILITY!! [wink]

We already have fifty thousand of the 'slammed' variety, no more of those are necessary.
Won’t happen because the Fiesta is a rollover risk. Raising the car will exacerbate that issue, potentially leading to lawsuits for aftermarket suspension manufacturers. If all you can do is lower it, then there’s no risk for the company... legally speaking.

I agree with this. Taking a sharper corner on a highway going xxx speed on stock suspension and stock rims definitely results in excessive body roll but the average owner isn't as dumb as I am. That's why I opted for a slight lowering. I can understand someone wanting to raise slightly though and stance the toe out a little further to compensate.
