They aren't too expensive for 16", are they?:dunno:

Damn...I can imagine my 18" set will cost a near $1k. :cry:
No, not too bad. $138 per tire. Still, lots more that I would like :eek:

A set of 18" Pilot Sports would be mad :yikes:

btw, anyone else ordered S-03s lately. My last set was supposed to be WR rated, but ZR was stamped on the tire.

I wonder what this will show up as....
YR.

edit: By the way, ZR is stamped on all tires rated over W. I think there are 3 different speed ratings, basically Z rated tires encompass all ratings over 149. W rated tires are rated over at 150-something so it'll get the ZR stamp. Y rated tires are rated at 180 something so again, it gets the ZR stamp. Then there's the truly Z rated tires that has no upper limit that can be tested on road going vehicles that simply gets the ZR stamp.

I'm pretty sure the 225/45/17 and the 225/40/18 S-03s are Y rated.

Often different sizes will have different speed ratings. Since these are all over 149MPH I doubt there's anything to worry about.

All the tires Z rated and above, have the Z rating on the tire. The SO-3's are Y rated, but still show the Z on the tire. My OEM tires, Dunlap SP 2000E, were W rated but also had the Z on the tire. Apparently that is the max rating they physically put on the tires, even though the actual rating is higher.

I just put SO-3s on the rear.

There are 2 ways this is done.

A W-rated tire can be labeled as:

225/45WR17
225/45ZR17 91W

I believe

225/45R17 91W

is also valid.

The 91 is just an arbitrary load rating # I pulled out of my ass.

you runnin' 16's or 17's on your car?

'thought it was the 17s on the 328s?

only problem i've ever had with s-03s (225/50/16s) is they have more grip than the blue pig (the wagon) has power. ha ha ha ha.
yea, 16s



A bit small looking :(
