Can't seem to find any discussion about this topic? Trying to decide if it's worth it to go wider in the rears.

Majority of the members seem to be concerned with fitting the widest tire possible without rubbing issues. Yes I know, wider tires look good. What about the effects on acceleration of added weight as tire size increases? For example, if the rears with Michelin PS2s are switched from a 225/40/18 to a 255/35/18, that's an added weight of 3 lbs per tire plus another pound or two for the proper rim width size to fit the wider tire. It doesn't seem to be much but I know a lot of people are concerned about decreasing weight as well. Does anyone know if the performance factor of a wider tire will always offset the negative aspects of added unsprung weight in terms of acceleration and of handling?

Thanks for your feedback!
