Anybody running 275 Nittos 555R tires on a 8.5" wheel? Nitto lists the approved rim width as being 9-11" for the 275/40/17. Will there be any issues running a wheel under the approved width? For those using the 275/40/17 555R on a 8.5", do you have any pics of the sidewall?
Thanks

 

275mm = 10.82"

That's a 2.32" difference between the wheel and tire, so 1.16" on each side. A 275/40 has 4.3" of profile height, and if you do the trig, that comes out to 15 degrees overall sidewall angle. That doesn't account for the crown of the tire, so the actual angle would be more.

You're right to question it. I don't think I'd do it. I'm guessing you already have the wheels, right?

 

275s come stock on 9" wheels. How bad could it be on a wheel a half inch narrower? That's only 1/4" for each sidewall.

 

I run 'em with no problems on an 8" wheel.

 

What size wheel are the wheels & tires? Pics?
Thanks

 

17x8 American Racing TTII's with 275/40/17 Nitto 555R's (I now have ES100's in the same size).

Here's a picture of when I was running the Nittos.



Here's a closer shot I just dug up.

 

That sidewall looks OK in the pics....and these wheels would be 1/2" wider than in the picture, NICE. It seems to be worn more in the middle of the tire, is that the normal wear to be expected with the Nittos?
Thanks for the pics!

 

275/40/17 555Rs will fit fine on an 8" wheel. They run smaller than most tires.
