I understand from the tech faq that when replacing SO2s it's necessary to upsize the rears to 245/45/16 to compensate for the fact that the SO2s have narrow rain channels. Presumably this is to ensure that the degree of rubber/road contact is maintained.

My question is - where does this advice come from? Is it Honda, pooled experience or some tyre guru? And if there is a 225/50 tyre with similar tread pattern to the SO2 - wouldn't that suffice?

It was based on advice received from Bridgestone, it used to be in the FAQ.

If you simply replace the S02s with RE050as, you can stick to 225 rears.

I concur with the gentleman above

Erm...

Now on my second set of 225/50 ZR 16 Toyo T1-R Proxes.

No issues at this call sign. Once scrubbed in, they stick like glue, even in the wet and I still get 9,000 enthusiastic miles per set.

However, a large number of Toyo users report excessive side wall flex... Presumably because they went up to 245s?
