What is the max tire width on a stock 16" cooper s rim
 

Im currently looking at a great deal for a set of 225-55-16 hankook ventus v12 tires but i would like to double check that it would be a safe size before i buy them.

Try this as a reference

205-55-16

225/55's are going to be a taller tire than the stick size. 225/50 should work on the 6". It will be beefy.

205/55 works.

We've used both 225/45 and 205/55 for track and autocross tires, we've never had a problem with them. 205/55 are a bit taller than stock, the speedo actually reads correctly. The 225/45 are shorter than stock. 225/50 are as tall as 205/55, I don't know if they'd rub anywhere.

225-50/16 Hanook R-S3 definitely fit on stock 16x6.5" wheels.
Lots of competitively priced performance tires available in that size as well (v12's are cheap, but not all that good).

225-55/16's would be 5.31% bigger in diameter vs. stock. Avoid going THAT much taller unless you explicitly want to do that for a compelling reason.

205/55 on the 6 inch rims work great

Check your tire source-

Hankook Ventus V12 Max Summer tires don't come in 225/55-16 but other Hankook UHP All Season tires (S1 noble2 and Ventus V4 ES H105) do.

Compared to OEM 16" tires, 225/55-16 is 1.3" taller in tire diameter and won't fit a MINI with stock or lowered suspension without rubbing. It is not a good choice.

What suspension are you running? Any plans to lower it? If so then you want a tire size that is at or less than OEM tire diameter of about 24.4".

For OEM 16" rims you can run tire sizes up to about 225 but why are you doing that? For looks? Then 225/50-16 is your best choice for street use but fits OEM suspension not lowered suspension. 205/55-16 fits the OEM wheel great and gives you a good tire selection/ and prices.

Realize that a wider tire may not look much different on an OEM rim vs a tire that fits the rim exactly. You may either pay more for the wider tire size or it may weigh more. A wider tire can increase rolling resistance and decrease mpg for a daily driver commuting car. Alternatively if you use a wider than OEM tire you can use a wide rim for the full effect. Wide rims usually weigh more and cost more.

It does for me, there are Dunlop ZII or Toyo R1R. There are also Toyo R888 or Yoko A048 if you want something faster.

Bertie is currently wearing ZII in that size I bought from TireRack.

OK, now it works for me, must've been searching in Hankook only.

Sorry, will edit my post.

225/45-16 fits rims 7-8.5" wide, perfect fit for 7.5" wide rim, tire diameter is 23.9" which will work with OEM or lowered suspension.

This size is good for Extreme Summer tires (treadwear 140 to 200) and R compound race tires (treadwear 60 to 100). So expect the rubber to be grippy but wear out fast.

Yea I opted out on everything since the guy forgot to mention that the tires are staggered. Thx for all the input though fellas.

Glad I ran across this thread, had to pick up new tires for my Justa this week, and this gave me some additional options. Ended up ordering some Contis in 205/55/16 for my stock 16" wheels. Hope to have them and get them on the car before the weekend. Speedo correction and a little wider tire sound good...

New Contis in 205/55/16 are on my stock 16" wheels (can never remember which style/name) and they fit, but clearance on the lower control arm in the back and on the strut in the front is a little close. Not in danger of rubbing under normal driving, but I'm definitely thinking about spacers to not only clear a little more on the inside, but also to widen the stance a bit. Not planning to lower it, so a little further out to fill the fenders will give it a beefier appearance.

Is the 225/50/16 going to provide more grip than the 205/55/16?

I'm not going for looks (although personally I like big sidewalls), just maximum grip.

Comparing the 225/50 and the 205/55 they are almost identical besides the width.

I'm currently running 205/50/16 on bridge spokes, Direzza ZII. Trying to decide if I should go wider.

edit: I suppose I could go with 225/45/16, and that would be pretty close to the 205/50 I run now, although tire selection is very limited. We'll see what sizes Dunlop comes out with for the DZIISS

Depends on your definition of "grip". :razz:
The overall tire patch area wont change, but its size and shape, and subsequently cornering stability and responsiveness will improve with wider tires:

The other variable to keep in mind is tire selection and price for the specific tire exact size. You can research by going to tirerack.com and looking at the quantity of tires and models that are available for the size of your choice.

205/55-R16 tires are near stock diameter, and reasonably popular among high-performance tire models.
225/50-R16 are also near stock diameter, and even more popular with the tire manufacturers (other performance cars must be using them). Somewhat surprisingly, the same tire models (RE-11a, RS3's) are CHEAPER in the wider 225mm size then the 205mm size. BFG g-Force Rival is only available in 225mm incarnation. Period.

YMMV,

Thanks. And with a stock suspension setup (well, factory sport suspension), there's no need for spacers?

Technically, the answer will depend based on the actual tire size. It may seem strange, but no 225mm wide spec-ed tires are actually 225mm wide: many are wider, some are narrower.

The only thing I can tell for certain is that Hankook 225-50/16 tires on stock 61/2JX16 MINI wheels do fit stock suspension without rubbing, without spacers. Front and back.

Thanks :thumbsup:
