what do you think of these wheels?

xford said:
I would run 245x40x19's on all four corners. 255's might fit all around but I think you would likely have rubbing at full lock on the fronts - rears are no problem. If you go staggered it just limits your tire rotation options and IMO I don't think an approx 1/2" of extra tire width is worth it esp. since the rims are all 8.5" wide (not staggered 8.5" and 9.5" like the Jaguar Barcelona wheels for example)..

I'm running a 255/40 all around on my Tucanas with no issues. Even with the Eibachs I have never rubbed.
 
Yea but thats an 18" wheel. I know i rubbed at full lock with my sentas even with just 245's.

I would stick with 245/40 or 245/35. 245s are prob the best look for 8.5" wheels anyway.

And yeah definitely do not go staggered Unless the wheels are staggered. I have to run wider tires in the rear because my wheels are staggered otherwise I would prefer To run the same size tire all around so I could rotate them.
 
245/40 gogo - it's just 1.74% off stock size. Can't wait to see how they look on the car!

+1 - I had to adjust my Fuel Filter because it made a bulge in the liner that caused my 245's to rub at full left lock with 20's - I would play it safe and stick w/ 245's - they are plenty wide
 
245/40s it is.
thanks for the info guys.
I'm going to attempt to restore the curb rash myself. I found a couple good how to's. Hopefully I will have them on in a couple months.

255mm is 255mm. The diameter shouldn't matter. A 255/35/19 is less than a percent shorter than the 235/50/17. I'm running 255/40/18; or about the same diameter as a 255/35/19.

255 isn't 255. check the wheels 101 thread when I talk about tires. Very few tires are actually the exact width that the measurement states and if they are it is on the rim width tested. There is about a ten mm variance in tire width. A 235 width tire could be as narrow as 231 and as wide as 240. Have you not noticed that there aren't any tire sizes that aren't in 10mm increments ending in 5? You can't buy a 230mm width tire. This is except for the early Michelin in full metric sizing but that is a special TRX model.

Respectfully disagree...The extra diameter pushes the extra width further into the wheel well at full lock. I tried 255's (same exact tire at the time) on my Senta 20's and no go on the Fronts. 245's worked with some minor tweaks.

I agree. Most measured on wheel of certain width from sidewall to sidewall at the widest point of the bulge. Mounted on a narrower wheel, that bulge measurement will be less. This may not matter if the rubbing point of contact is on the tread shoulder. However, if the rubbing point of contact is mid sidewall, a narrower wheel will reduce the rubbing.

The measurement has nothing to do with a mounted tire. It is the width of the tread.

No it isn't. A wider rim makes a wider tire. It is the widest part of the tire. Do some research. Go check a tire manufacturers website. P-metric tires are measured at the widest point of the tire. In fact just about every kind of tire is measured at the widest point. Tread width and the width of the tire are also not the same for the same size of tire. Go check Dunlops website. My 245/40r18 direzza tires are approved on rim widths from 8 to 9.5 inches and measure on a 8.5" rim, 9.8 inches wide. That is the section width, not the tread width. A yokohama 245/40r18 Advan sport has a preferred rim width of 8.5 but can be mounted on a 9.5" wide rim. On a 8.5" rim it has an overall width of 9.7 inches and a tread width of 8.7". 8.7" converted to mm is 220.98mm, how is this a 245 wide tire? If you convert 9.7" to mm it is 246.38, which is closer to the 245 on the side of the tire? Please note how the dunlop is .1 inches wider than the yokohama even though they are both measured on a 8.5 inch wide rim. The 9.8 inch wide converts to 248.92mm.
 
From Tire Rack Specs Section:

Tread Width

The tread width is the distance between the outer edge and the inner edge of the tread of a new tire. However today's radial tires often feature tread designs that incorporate rounded shoulders and there is no industry standard pertaining to "how much" of the rounded shoulders should be included in the tread width measurement. Because of this, it is difficult to accurately compare the tread width differences of one tire brand to another. Tread width measurements are best used when comparing the various tire sizes or lines manufactured by a single tire manufacturer. Several tire manufacturers have chosen not to publish tread width dimensions.


Section Width

A tire's section width (also called "cross section width") is the measurement of the tire's width from its inner sidewall to its outer sidewall (excluding any protective ribs, decorations or raised letters) at the widest point. This measurement is made without any load placed upon the tire and after the tire has been properly mounted on its industry assigned measuring rim and has been inflated and reset to its test pressure after 24 hours.

Because a tire's section width is influenced by the width of the rim upon which the tire is mounted, the correct industry assigned measuring rim width for the tire size being measured must be used.

The width of a tire mounted on a narrow rim would be "narrower" than if the same tire was mounted on a wide rim. NOTE: because the overall diameter of a steel belted radial is determined by the steel belts, there is little, if any, change to the overall diameter of the tire due to differences in rim width.

The industry rule of thumb is that for every 1/2" change in rim width, the tire's section width will correspondingly change by approximately 2/10".

For example: a tire in the P205/60R15 size is measured on a 6.0" wide wheel and this size tire has an approved rim width range from 5.5" to 7.5" wide. The tire has a section width of 8.23" (209mm) when mounted on a 6.0" wide wheel. If that tire were mounted on all of the rims within its approved range, the tire's approximate section width would change as follows:

Difference from
Measuring Rim Rim
Width Approximate Tire
Section Width
0.5" narrower 5.5" 8.03"
Measuring Rim 6.0" 8.23"
0.5" wider 6.5" 8.43"
1.0" wider 7.0" 8.63"
1.5" wider 7.5" 8.93"

Because of the different wheel widths used in the above example, there is a 9/10" projected difference in tire section width when comparing a tire mounted on the narrowest rim to the widest rim within its range. This may affect fenderwell and frame clearances when selecting optional aftermarket wheel and tire packages.
 
X, we could argue about this issue forever until the FTC comes in and sets a measuring standard for tires. This whole thing reminds me of the computer display measurement fiasco back in the 90s. That's why they had to denote the viewable diagonal dimensions and had to change the model number naming scheme. Point is they should measure all tires at the tread shoulder at the maximum rated pressure and that's it. There is one company I know that helped start this whole debate and that is the one that rhymes with the Wood Rich. Radials started this mess too.
 
It isn't a debate. It is wrong to think that all 245mm wide tires are exactly 245mm. It is also wrong to say that tire is the same width on any width rim. All tires are not created equal and that is the point. Some people did not get that point but hopefully they will.

I'm talking TREAD width, NOT SECTION width. I've had 245s on an 18" wheel rub and now 255s that don't. Offset and SECTION width were the determining factor.

In any case.... DONE!
 
<Yawn> all this d*ck, I meant tire sizing is making me sleepy ... Who cares ?

Hey, when I need new tires, I go to the store and Fn point at the prettiest ones on the rack, tell them to put them on and not F me around about the damn disposal fee, put the spent ones in the trunk, then on a Sunday I swing by the local Go-kart track and toss the old ones over the fence. See ya!

I agree with you X. Keep in mind however, when you get into the extremes, the section width will be won't change anymore as this example in the link shows with a wheel width of 7.5" which is really too narrow for the 255/35-20 on this car.

Here, the widest portion of the tire is the tread because the wheels are almost too narrow.

Btw, even with the narrow wheels, she cornered like a race car!

Man, I never thought of that. Great idea!

+1
 
Just a thought, with as many wheel / tire threads which come up, would it not be more effective to try and build onto the existing sticky thread on wheels (Wheels 101) that Bull authored by trying to direct questions and replies there?

We have a ton of wheel threads and one could get lost in them.
 
Was wondering if anyone could suggest a rattle can paint that would match these wheels. I want to touch up the couple of curb rash digs without repainting the whole wheel if possible.
