285s?

[brentalan]

What do you folks thing about putting 285 40/17 tires on a 17x9 Cobra R wheel out back. Will it fit on the 9 inch wheel?

I currently have 275 40/17 in the back and I do get a little rub on the worst bumps at highway speeds. Would the rub be worse with the 285 if that in fact does fit?

I dunno man, I have VERY little room btween the stock sway bar and the tire on my 98, and it's even closer on the 95 with the aftermarket sway bars. I KNOW people have put wider rubber on thiers, but don't exactly know how.

The rub would be worse, it would have to, its wider. How bad is hard to say. You may want to identify the rubbing location, usually the quarter lip right above the bumper cover and the bumper cover edge too. These are pretty easily modified for clearance, as long as you have the guts to take a body hammer to your car. I have 265/40/18s on 9.5wide. It probably is worse than the 275/40/17 on the 9wide. I rolled the lip from top center back more as it went back. It only rubs the bumper cover edge once in a while on a real bad road, that could be nipped a good 1/8 to 3/16 without even hitting metal, but does it sooo little I haven't bothered. Mines pretty low too.

Go for it Brent!! Sure it'll rub, but it'll look awesome.

Thanks guys, I think I'll just stick with the 275s. They look pretty good

This is an old thread, but for reference.. I have 11.5" wide BFG's on mine, I know your car isn't lower. Not while driving anyways. And I don't rub. I trimmed the bumper cover, and rolled the lip from the ten o clock position (looking at the drivers side) all the way including what the bumper cover *use to* screw to. I rolled that f'r also.

I also have the 1 3/8 addco bar.

You simply can't stuff more tire under a mark with an o.a.dia of 26" without rubbing unless it sits higher, and to have a wheel without as favorable offset will probably still stop you anyways.

I have a 9" by pos 36mm? offset, I believe.

The other day I test fitted a OEM gt500 wheel onto the rear of my mark. They are 9.5" wide with 45mm offset and 285/40/18 tire.The wheel itself cleared everything perfect, even the swaybar, but the tire touched it. Clearance to the quarter lip was close to what stock is and it looked perfect, without any rubbing issues. I know that a small 3mm spacer would take care of the sway bar rub.

Interesting.

The reason I stick by not being able to shove a wider tire under a mark as low as mine, is because the letters on the insides of my tires rub right above the shock mount, I can see where it takes off the dust when I pull the wheel off, yet it doesn't wear my letters away off my tire. And, I had to trim my bumper cover to even let the car sit by itself without the body resting on the tire.

You thinking of going with the stock GT500's? I'm curious to their appearance on a MARK.

They looked a lot better on the mark than on my buddie's drop top gt500.

Too bad the front would require 10mm spacer to clear the spindle.

The rear would require custom sway bar. Other than that it would a very well fitting wheel/tire combo.

Remember that BF makes some of the widest spec'ed tires.
Compare Nitto 555R DR and BF DRs - it's at least 1" difference between corresponding sizes.

Lol not surprising. Not a new mustang fan myself.

You'd need custom hc spacers, also I bet.

I didn't know how much difference, but I realized right away BF under-rates.

..so I said 11.5" BF instead of 275, but they are 275's...... Lol. You are right. Another brand and I could fit a 285 possibly, but not if it were more than 11.5" wide. Someone else with less attractive offset prob can't even fit a 11" tire, unless they're ridin higher.

I know [ahem] on the markviii.org totally messed up his stuff trying to fit 255's? on a 9.5. on a Gen 1. Lol then he was so mad like a three year old he blamed it on the bolt pattern and bought the wrong offset again just to be able to say he's done the 'smart' "hub change" in an 8" wheel so the new car's as ugly as the old one for twice the price. Ha. Moron. People need to be careful when fitting meats on these cars, it gets expensive.
