Ok I'm a little miffed here, I'm putting some 17" alloys on to allow bigger brakes and therefore improve handeling but I've seen people on here say that bigger wheels slow the car down. I don't really understand this as the way I look at it a bigger wheel is like a bigger cog, turn the smaller cog and for every rotation you cover a larger area with the bigger cog, if that makes sense. So a rotation of a 17" wheel covers a greater distance then a rotation of a 16" wheel. So by turning that wheel at the same speed you're covering a greater distance in the same time, thereby going faster. the only restriction to that being weight perhaps but light weight alloys should overcome this?
But from what people are saying thats not how it works, so can someone please explain to me how it works?
Also how much speed is actually lost as you go up the wheel sizes? I may be putting an inch bigger wheels on but I'm also putting on ultra low profile tyres so the overall size will stay the same (hopefully that means I wont have to have my spedo etc.. re-configured) so I'm liable to loose any speed?
