What are you feeding this "Tire Size Calculator"?

As far as the ABS and speedometer are concerned, the important factor is diameter, or revs per mile. Those will be very close for any 225/50-16 tire. There's less than half a percent difference between OEM S02 (840 revs per mile) and the RE01R (837 revs per mile).

I would call that "acceptable"!

I knew something hadda be off there!

BTW, it's not the 225/50-16 size that's "too slow", it's the 245/45-16 that's too fast. OEM is 24.8", 840 revs/mile. Most 225/50-16s are 24.9", 837 revs/mile. Most 245/45-16's are 24.6", 847 revs per mile.

Stock, the speedo most likely reads ~3% high anyway. With 245/45s it'll read another 1% high. Not a big deal, but just so you know...

FWIW, your tire size calculator is basing revs per mile on the unloaded tire radius. Loaded radius is about 3% shorter, which is why actual revs per mile are greater than what it calculates.

No 225/50-16 or 245/45-16 tire will screw up your speedo, odo, or ABS, so don't worry about that.

why not just use oem so2's

ZDan

Because there are better tires available for less money.

It's a OEM specific tire that comes at a premium and with wait times.

If I could get a tire that meets it in the dry category and costs less, why not?

I've found the RE-01R exceeds the performance of the S-02 in everyway and the .2" smaller tread width isn't anything that is noticeable to the eye, much less the road.

The wet weather performance of the RE is amazing compared to the OEM S-02's also, and I drive it like I would any decent all-season tire in rainy conditions, something I couldn't do with the S-02's. That, combined with them being cheaper, make the RE-01R a no-brainer IMO.

The only thing that I prefer about the S-02 is the appearance, the RE isn't as attractive, as it does have more of a "track" tire profile.

Good to know, Sbeall - thx. Am having a set mounted tomorrow, shipped to my installer from tirerack (grt service!).

Main thing I was looking for was better wet performance than my S02's without giving up anything in the dry. The S02's were pretty far gone in the rear, with 12K on 'em and downright dangerous in the rain. Fronts have lots of life in them, so I'll probably try to move the set on ebay or somewhere - might make a good cheap autox set for someone wanting to run street legal rubber.

I'll weigh in with my impressions of the RE-01R's once I wear the shine off 'em.

225 RE-01R is more than enough on the AP1 rear wheels and had substantially more grip than 225/245 Hankook RS2. On our 2nd set of 205/225 RE-01R's and very pleased. I'm also putting a set on my Elise since the near R compound A048LTS are almost dead.

Any input on sidewall stiffness? Love the tight feel the S-02's give
