225 RE050a
With all due respect to Honda's recommendation of 225 RE050a replacing S02s, how do they fit? I have some "place holder" 225 Toyo Proxes T1-R tyres and it is quite clear that 225 is totally wrong (too skinny) for the rear. Do the RE050a also have a 245 foot print like the S02 or are they truly 225s?

I have the opportunity to check later today. I'm putting on a newly refurbed set of 16" with RE050A (205/225) and removing the original wheels with S02's.
I'll line them up next to each other while the car is up on stands.

In theory the width should be the same.
However, the rear S02s had a larger contact area (i.e. less tread/drainholes) so actuall more rubber was in contact with ground than normal 225s (which all have larger rain channels/tread etc.). That's why it's always been recommended to go for 245 if not s02s.
It is my understanding that the RE050s have larger tread/drain channels than the s02s so for the equivalent amound of rubber contact (i.e. grip!) you need larger size.
I could be wrong but I've never had conclusive reasoning to say otherwise.
Basically you want as much rear grip as the S02s provide.

The S-02s had a wider tread (245) on the (225) carcass, which is why they look so 'square'.
The larger carcass will pull the sidewalls in a bit further, resulting in more internal slip (squim) than a 225 would.
Also I understand the the 050A is not yet available in the 'correct' 245/45-16 size, which is thy everyone is going for the 'recommended' size.

I remember putting some S03 225's on a few years ago and the rears lasted about 6000 miles.

Well, I will go for the "recommended" 205/225 in RE-01Rs then, since they also don't have the 245s in this yet. They are only place holders for when switching over race/street tyres on my 17" anyway.
Thanks a bunch.
