Thanks for this link. I learned more in 20 minutes of reading this than all the years of driving. Thanks

 

I would expect 20-25k from any one of those 3 tires, (Es100, Gs-D3, S-03_ with somewhat spirited street driving and regular rotation.

I second that NOBULL

Great link, finally got some things figured out!

 

there are so many factors at play, not even based on the vehcile. This pieces of the puzzle are things I don't know about the Euphori test.

Pavement type, we're on blacktop.

Weather conditions - its was overcast, and about 52 degrees, and very windy. This day wanted to rain in the worst way but didnt. Any Max performance tire will begin to give up its compliance with the pavment.

Course setup - These runs were cold - out of a parking lot, thru a quick 4 cone slalom, and right onto the pad. 3 laps clockwise, 3 laps counter clockwise. I would venture the tires wewre warmed up by the last 1 or 2 passes. (of 6 total)

Driver's metality - this event was a 1 shot deal, infront of 200 people, in less than ideal conditions. I know that I would be down just a step, from how I would run a pad on the salt flats in June in front of 2 buddies.

I hope this might shed a bit of light on these results.

>>Don't the stock Euphori@s get .86? I'd think moving up to a significnatly grippier tire would make more of a difference! Or does the road holding have more to do with the suspension?

 

Its a choice depending on what class the one lap er wants to participate in. I will dig up the class sures for retro. More to come soon

If you liked that, be sure to check out The Suspension Bible as well.

 

Hey Alex, would you mind going over that load rating thing again? I was planning on getting 215/40/17's so I could finally take off this stupid bandana.

Also, I don't "do" rain. These S-03's look like snow tires to me. Is there something with a little more tire in it that will give better dry performance?

 

215/40/17 if run at 36 PSI, still lacks 59 lbs a tire in load bearing ability.

You could check out a few of these tires.
Sp Sport 8000
Rosso Aysemetrico

I can't promise this size is a trouble free fit, but I know of 1 very fast cooper on these in 225/45/17
K D

I would personally run S-03

I don't follow?
A 2678lb MCS w/ 63% on the front has 844lb on each front tire.
The 215/40/17 S-03 tire is rated at 1073lb at 35 psi
Where's the problem?

I think it has to do with weight transfer and payload capacity too. A loaded down MCS under heavy braking conditions would put those tires well over the rated limits.

 

I would tend to agree with Azweed, that transitional and cornering forces exert high degree of force on your tires.

My feeling is that BMW engineered this automobile for a certain degree of load bearing per tire, chosen in its combination of horsepower, and suspension geometry. I feel your tire's response and ability to carry weight are integral parts of a Mini's suspension. Think of it as the final component in your suspension.

Would we want to use Chevy Cavalier parts, on our MCS? Surely not, as BMW knew more about this design than Chevrolet. I personally would not claim to know more than Mini's engineers.

Alex

 

In a 1G corner the tire carries weight x sqrt(2) or 1200lb but somehow I doubt the average tire shopper knows that. The tire manufacturer rates the tires based on the vehicle weight and has already factored in the handling forces. The vector addition is not left to the buyer.

I'm going to assume that you didn't crank through the trigonometry and arrive at the same sqrt(2) factor I did. Can you tell me exactly what your math is? Are you just reading the load rating off the original tire and sticking to that?

B.T.W. the Goodyear RS-A recommended by your company in the factory size of 205/45/17 has virtually the same load capacity (1102lb) as the 215 sized S-03 I'm talking about. Same goes for the Parada, and your top selling eufori@ and SP 9000.

 

I said:
>> Until something changes my mind the only thing I'm planning to change when these wear down is to switch to 215/40s rather than the 215/45s I started with.

Well......I think something just changed my mind...I had no idea how much of a difference it would make in the profile until I found a pic of the 215-40 S-03s on 17-7.5 SSR-Cs. Sure I can run the numbers, but a picture is worth a thousand words...or numbers.

I hope this works, never posted a pic before. If it doesn't, the URL is:

You will find that manufacture's maximum load bearing capacity can greatly diveate between manufactures.

The benchmark Tirerack use is Bennett-Garfield tire guide. The inflation and load bearing capacities in this publication are provided by the TRA.
The Tire and Rim Association has been the rubber industy's benchmark for last 100 years.

Alex - or anyone else who knows

I get the impression the S-03s are a bit heavier than most of the other good street performance tires....true? How much do they weigh in 215-45-17? Can you compare this to weights of some of their closer competitors? There are a few sites that track and post wheel specs (including weight) but I haven't been able to find tire weights.

thanks - sdw

 

Yes the Bridgestone is slightly heavier than other tires in this size.

Here is the post on weights you've been dreaming of!

Alex

Thanks Alex, and even though you didn't ask....yes, I do feel stupid for overlooking that post.

I think it's interesting that the two tires you've mentioned as being close contenders - Bridgestone Potenza S-03 and Goodyear Eagle F1 - are listed at the same weight (25 lbs) in 215-45-17. Must be hard to beat that weight and still get good all-around street performance.

 

I have found the performance gains in those tires really tend to offset the ounces of weight gain.

Hi Alex,

Upon checking out the tire weights you posted in the 205/50x16 size, there is more than a few ounces of difference between the S-03s and the Goodyear F1 GS-D3s. The difference appears to be two full POUNDS (22 vs. 24 lbs). Wouldn't this make a noticable difference in handling when comparing the two? I was considering the ultralightweight 19.5 lb. Toyos until I read the above post about turn-in squirminess.

I am interested in the 16x7" SSR Comps, or even better, the 6.5s if they ever become available. (Is the 6.5" width vaporware?) I am currently using the std MINI V-spoke 16s with the Dunlop RunFlats.

Last question. Since I plan on going non-runflat, how difficult is it for a tire shop to clean out tire sealer off a rim and tire if it ever has to be used? Will tire sealer affect the balance of the tire?

Thanks Alex!

 

Alex,
how does the S-03 compare with the Kuhmo ecsta MX in terms of performance and wear? they would be a lot easier on the wallet when it comes time to replace, but do they lack anything performance wise?

Thanks.

** I would still lean to the s-03 for transitional stability, and wanter performance that does not tail off as it ages.

** every single wheel; SSr sells is tested and evaluated before it leaves. Not 1 in a batch, EVERY wheel is examined. This are on there way.

>>Last question. Since I plan on going non-runflat, how difficult is it for a tire shop to clean out tire sealer off a rim and tire if it ever has to be used? Will tire sealer affect the balance of the tire?
** tire sealant can prove to be amajor pain for any shop to remove from Any wheel. Yes it can affect balance, as it adds mass.

I feel that the MX is really closer in dry conditions, and may last a bit longer.

S03 is much better in water.
If I were to split hairs, I like the way the s-03 breaks away,
its easier to bring back than Kumho's.

If anyone is interested, there are a set of 215-45/17 S-03s mounted on 17x7 OZ Crono Evolutions available for sale in the marketplace.

 

Thanks FWD-MX5 for your review and for starting this great thread. You sold me on the S-03. Today I ordered them mounted on SSR Comps 16 X 7 in anthracite from Tire Rack.

 

HARMINI,

Congratulations on your selection of wheels and tires for your MINI !!!!!

Please post some pictures after you have them installed :smile: !!

I am still leaning toward the RH Evolution CP8Rs in the 17 X 7 size.

Best Regards,
Ron
