Hi Jim,

I'm currently running 17" Volk CE28N-Ls in the popular S2000 sizes...

fr: 17 x 7.5 +50
rr: 17 x 9.0 +63

...with the OE RE-050s...

fr: 215/45R17 87W (S2000) - tread width = 6.7"
rr: 245/40R17 91W (S2000) - tread width = 9.0"

I'm very pleased with the RE-050's performance but would now like to upgrade to the next sizes. Looking over Bridgestone's and Tire Rack's web.site, I'm thinking the best option to remain closest to the OE stagger is as follows...

fr: RE-050 225/45R17 91W (Mercedes) - tread width = 7.3"
rr: RE-050A 255/40R17 94Y (standard) - tread width = 9.1"

Any thoughts on this setup? Also, the "Mercedes" 225/45R17 91W is listed as a "runflat" tire on Tire Rack's web.site but NOT on Bridgestone's. Can you please confirm if this is a runflat or not? Is there anything about this tire that would make it inappropriate for the Volk wheel?

Thanks very much in advance!

Notes...
- "standard" RE-050 225/45R17 91Y - tread width = 8.3" (!)
- "Mercedes" RE-050 245/40R17 91W - tread width = 8.2" (!)
- all numbers pulled from Bridgestone's & Tire Rack's RE-050 spec sheets

 

Hello Jim? Any comments? Thanks.

 

Take a look at the specs for the Yokohama Neova AD-07, 205/50-17 and 255/40-17. Those are about the same stagger as the stock tires.

I have 225/45-17 and 255/40-17 with a slightly non-stock suspension and have been happy so far.

 

Bridgestone does make both a run flat and a non run flat in that size. The regular tire would be fine but I would not do a run flat tire on the car. What is it you are looking for out of the tires? I may be able to make a recommendation for you.

 

At this point, I'd like to stick with the RE-050s and the "Mercedes" 225/45-17 seems like a very good fit to better match the 255/40-17 RE-050As I'll be running in the rear. However, I'm just confused if this "Mercedes" 225/45-17 is a run-flat or not (Bridgestone does NOT list it as a run-flat while Tire Rack does). I don't think the "standard" non-run-flat 225/45-17 is a good fit since it has a tread width = 8.3" (not enough stagger with a 9.1" rear).

BTW, why do you not recommend a run-flat for the S2000?

Thanks.

 

Curious too.

 

I think run-flats would be too heavy.

 

Actually, according to the spec sheet on Bridgestone's web.site, this 225/45-17 RE-050 for the Mercedes is the same weight as our OEM front (22lbs). Assuming the former is a run-flat (still to be confirmed), its weight might be distributed differently, but I'd figure this would be negligible in the grand scheme of things.

Anyway, I'm still wondering...

* is this "Mercedes" 225/45-17 RE-050 truly a run-flat?

* is there a NON-run-flat 225/45-17 RE-050 or RE-050A w/tread width = ~7.0"?

* why shouldn't a run-flat be run on an S2000?

Again, just trying to clarify things stated here and discrepancies between Tire Rack's web.site and Bridgestone's.

Thanks.

 

Hi Jim,

Can you please clarify this for us?

Thank you.
