I could only get Ws for mine back in June, and believe me the side walls are soft on them too. I have not felt any unusual handling issues with mine
Hmm, seems like the jury is out then. Having read Cue's post again, it would be a pity if the PS3 W rated tyre is both heavier and has a similar flabby sidewall as the V. Sounds like there is no real benefit to a W tyre.
Spitfire, although you have noticed no handling issues do you think the tyre is heavier? More unsprung weight not good. Guess the only way to tell is to put a W fitted to a Speedline on a pair of scales back-to-back with a V or a PE2.
Sounds like too much hard work unless you have spare wheels with tyres lying around!
