Well the Tirerack finally has specs listed for our OEM tires (the info used to be blank). Notice our OEM rear tires are 0.4" wider than the Porsche OEM model even though the tires are both 225/50/16s -- and they were both measures on 7" rims. Also notice our OEM front tires are more narrow than the Porsche OEMs even though they are both 205/55/16s -- and the Honda OEM were even on wider rims!

Size.............................................. .UTQG......Inflation...Rim Width Range...Meas. Rim Width....Tread Width
205/55WR16 89W SL (Honda OE)...140 A A...44psi.......5.5-7.5".................6.5".......................7. 1"
205/55ZR16 N3 (Porsche OE)..........140 A A....44psi......5.5-7.5"..................6".........................7 .2"
225/50WR16 92W SL (Honda OE)...140 A A....44psi......6-8".......................7"....................... ..8.5"
225/50ZR16 N3 (Porsche OE)...........140 A A....44psi......6-8"......................7"........................ .8.1"

That's right baby...the stock S02's are wider than my 245/35/18 Toyo T1-S's and they will be wider than some 255/35/18's also.

 

Well I'm not quite sure of that. I don't think you can really compare across brands since each manufacturer might measure tread width a little differently.

 

thanks for the info!

I just spoke with a Bridgestone Tire rep (the mfg not a dealer). He felt the current shortage of S-O2's was likely due to the fact they intend to discontinue it in favor of the new S-03 PP. I will try to get further confirmation from the factory reps at the Drive & Learn event this Friday. This would be a good time to get a set of S-O2's if you are partial to them.

 

Rim width affects tire width (cross section width) but not tread width (at least not appreciably).

Check out the tread width 205/55R16 for the Yokohama A032R

I'd bet my bottom dollar that rep was clueless -- kinda like most Honda dealers are clueless. The S-03 PP is likely replacing only the S-02 PP. The non-PP S-02 line is entirely made of up OEM tires now. Originally (I believe) this was not the case but the S-02 PP line came along thus the only 'regular' S-02s left are the OEM ones. Bridgestone and Honda would have done the R&D together only to stop making the tires two years later! Not to mention getting rid of the non-PP S-02 line would also get rid of a lot of OEM Porsche tires. I'm sure Bridgestone would prefer that Honda and Porsche continue to use their tires as OEM.

 

You guys post that the OEM SO2's tire PSI is at 44, I have mine at 32 is that too low, on the sticker on the car honda recommends 32 all around. what do you have the psi at?
