Some freinds with a Renault Megane want to go for a bigger wheel / smaller tyre size combo to help improve the handling of thier motor, the sidewalls at the moment tend to roll around a bit!

They have 185 / 60 / R15

What could they go to to keep the same rolling radius and not put speedo etc out?

Are they just looking at 16's, or would 17's be possible? They don't want to ruin the ride totally, and if the tyres are to thin then the dashboard may fall apart.......

Thanks

 

Have a look here: TYRESAVE: Tyre Size Calculator

andling depends on so many things that just changing tyre aspect proably won't do much, in fact not even enough to notice
