I finally got rid of my RE10's after 22,000 miles and they were looking totally destroyed. I opted for PZero Asymetricos purly out of personal preference. I have seen a pictures and more noticably a 22B with PZERO painted in Yellow on the tyre wall, is this on a different tyre or simply Halfords Tyre wall paint. Totally insignificant I know but it would be nice to know.

 

My P Zeros aren't yellow painted either, gutted.

I think I remeber reading that the P Zeros on the 22b are made specially for the 22b.

That might be the answer.

 

22B PZeroes do have the name in yellow...
