285 DR's on a 9" rim What are the potential problems with using a 285/35/18 tire on a 18x9 rim? 275/35 is the ideal size for this rim. But anything bigger is suggested to be on a 9.5 or bigger rim.
Just wondering If i can use the Nitto 555r 285/35/18 on a 18x9 rim??
thanks
Chad

a simple no would have worked. Maybe a reason as to why they dont fit. Thanks for your smart *** comment! I looked on the Nitto's site that is why i said in my post it wasnt a recommened fit. What problems would i run into going 1 size wider? Seems like a small amount. So did you even read my post, amazing what you can find reading before posting....

I read your first post, and I have read your second post . . .
Why don't they fit??
WHY?
You demand a reason as to WHY they don't fit?
Your asking a forum of internet warriors WHY???
They do not fit because the MANUFACTURER says they don't!!! SURPRIZE!
What more do you need?
Yes there are plenty of ignorant people and careless tire installers that will install the wrong tire onto the wrong wheel. So does that magically make it OK because some fool did it?
Yes many have forced a 315/35R17 onto OEM 17" x 9" wheels, so I guess since Joe Bob did it it's perfectly acceptable . .
Others have forced 295/35R18 onto 9.5" wheels . . .
WTF is the point of running too big a tire on too small a wheel?
If you knew your answer then why ask it?
My smart *** answer comes from years of answering the same damned stupid question over and over.

Xsta Z28,
I asked because i wanted someone like you who has a better knowledge of tires than i do for an answer. I guess i did already know the answer. I just wanted to know the promblems that it would cause. Just hard to understand why a 275 fits but not a 285. Seems like such a small amount to go from being the recomended size 275 on a 9" to a 285 being "not safe/ not recomended". Now of course i would never attempt to put 305 on a 9" rim because someone else has made it work. But in that case maybe there is not limit to being not safe. If it dosent fit it dosent fit. I tried not to be the dumb question guy and i guess i was pissed when you gave me the dumb question guy answer. Thanks for your time and explantion.

Here's my take, for what it's worth and I'll probably be flamed by a mod for this. I was recently looking to see how wide of a drag radial I could run on a 18x9.5 wheel. I did some search on here and corvetteforum and found that a few guys over there have run a 305/35/18 Mickey Thompson drag radial on this rim size. They reported NO sidewall bulge and were very happy with how the tires fit the 9.5" wide wheel. If I were you, I'd look at the difference of section widths between this tire and the tire you're wanting to run and see if you want to attempt it. I can't speak for everyone, but the lateral loads we put on these cars as daily driver or straight line machines, sidewall flex/rolloff becomes much less of a concern compared to a vehicle going to be used in autocross type competition.

Those mundain round rubber donuts are the ONLY thing keeping your car safely on the ground.
A square peg WILL fit in a round hole, you ject need a big enough hammer.
The wheel size affects the sidewall hieght, thus affects what will/should fit on a wheel, that is what I am referring too . . .

So again just because you've found some one on the internet that is STUPID enough to force too big a tire onto too small a wheel, it is perfectly acceptable to jeopardize your safety, possibly your life and all of those who drive around you? Smart, real smart.

I know but the OP is asking about 18" wheels, not 17" like you are running . . .

No you don't. You just need the diagonal measurement of the square to be less than the diameter of the hole and it'll slide right in.
To the original poster. Every tire manufacturer is a little bit different in their measurements. Point is, every 275 wide tire isn't exactly the same from one manufacturer to another. That's why some tires of the same size look different than others. Nitto's typically run on the narrow side, so if you are running narrow with a 275, try a 285 and see how it fits.
I've heard the argument that 5x120 wheels will cause my car to explode going down the road, but after taking measurements of factory wheels, vs. mine, the factory wheel that was 5x120.65 was actually 120.21mm and my Ruff rims were 120.28mm
.So the moral of the story is, buyer beware. Just like was stated, don't beleive what you read or what you're told. Do your own research when it's you car on the line.
