Tire Size Question Options

[DanKimber]

On a 16" rim, what is the widest tire anyone has went with out rolling the fender lip or other modifications? 215/45 ? 225/50?

Thanks,

You have to tell us how WIDE your rim is.

[DanKimber]

No I do not believe that I do, at the moment I have some 225 tires crammed on 6" wide rims.

But they would be 7.5"

Are you trying to say that rim width doesn't matter when trying to fit a wider tire? That proposition is ignorant. Rim width is THE controlling variable about what size wheels you can "fit" on the car - not tire size (of course both matter but rim width is MUCH more important). Tires expand to fill out the rim. Beyond that, fitting a rim without rollinig fenders or interfering with suspension components is a product of rim width and offset.

Now for my second point. Let me get this straight: You have a question. People with more experience try to help and then you come up with a statement like that? Am I missing something here or is that a little insulting?

Anyways Offset and Rim width.

7.5" is just about perfect for a 225/235.

I have 225/35 and 255/35 on a 8" wide rim

I belive this topic can help you. There are recommended rim and tire widths combinations

[DanKimber]

Thanks for the link to the table, and no I did not mean my statement to be insulting, sorry if it was taken that way. Yes rim width is a limiting factor, but by no means do people always stay within the recommended guidelines on the chart. It is also possible to purchase any rim width that you want, within reason, for a giving tire diameter. IE get a tire size that meets your needs and then go buy a rim to match, not other way around. There are lots of old VW guys running 13"X10" rims (not for sure what it would be like to drive on a square). Reguardless it has to clear the strut on the inside, not rub the wheel well up top or hit the wheel well as it sticks out the side. (though it has been interesting seeing the sawz all technique to make bigger tires fit)

Rim would be 16X7.5 my issue is that I do not see any real low profile tires set up to autocross or track day on, either falken RT615 or Kuhmo MX, or Hancook 712 (think I got the model number right). Even the hoosiers at this size start to get big in diameter. The tire sizes I see all put me at the same size as what is on my 02 Minivan about 26.6" in diameter compared to about 23" diameter. Just looking at a tape measure and the wheel wells I think that the best on a 16" rim would be a 215/45R16 Falken. This would put me at about the same size diameter as my 205/55R14 Hoosiers. I have also run the 225/50R14 BFG R1s and did not have a clearance issue. This should be similair diameter and a little bit wider then the 215's.

After I just babbled away for a whole 2 paragraphs I guess the real question I should have asked is anyone running a 215/45R16 with about 1" of suspension drop and are they having any problems?

Thanks,

Ok. Now we know its 7.5" rim width. Tell us the offset of the rim and we can give you a correct answer to your question.

[DanKimber]

Thats what I get for typing and watch my daughter at the same time +32mm

[jgreening]

My car is +33 all the way around with 7.5" rims so your wheels will stick out 1mm more. This means the fronts will DEFINITELY be fine. The backs on mine have never rubbed but the outside edge of the back tires is right underneath the lip of the fender. My car is lowered 1.75" and I have never had a problem. Also, the diameter of my my tire is 1" more than a 215/46/16 so that means that the tops of your tires will be ANOTHER 1/2" away from the tops of your wheel wells than my car.

In short, they should fit and have no rubbing problems. The should look very good too. Good luck.

here is a pic of garys (gt4wrc) gt4 with 16*7.5 wheels with 225-50-16 tires. in my opinion, the best setup on our cars other than maybe 225-45-17. damn i wish i got 225-50 instead of 205-50's . if only i could burnout .
