The rolling radius only affect acceleration!
It depends really from where you are coming from 15s 16s etc. And to day they ruin handling is not quite right really they do change the way a car handles though.
As you say there is less flex in the sidewall cos they sidewall is a lot stiffer. This reduces the amount of shock than the tyres can absorb thus making it a harder ride. Also if your cornering hard on an uneven surface then the car can be a little unpredictable mainly cos it can bounce more over undulations in the road, and there is more chance of the car losing control. Where as a fatter tyre can absorb these.
Because of the unpredictablity element that is being added by the bigger tyres this is why people say they ruin handling.=
Was a Clio 1.8 16v
I thought grip round corners in the dry was very good with my 17s, not worse than my 15s, although it was a LOT slower and a harsher ride so i sold them.

you learn something every day!
I wouldnt say they ruin the handling of say a car designed to run 15s. Its just different. Assuming youre running a wider wheel and tyre which almost always is the case when moving up to 17s, you have more outright grip but theres less flex in the rubber, so where before you might be squealing around a corner and just maintaining grip on 15s, the 17s with wider rubber have more traction but are more prone to snapping into a slide because they cant deform to stay flat to the road so easily. I guess you could say that smaller wheels on larger profile tyres are more progressive, you can tell what theyre going to do, whereas on low profile tyres you need to get used to when theyre going to slip.

Yes but your talking about offsets and widths etc. The question was solely about what difference does the size make (and weight!) It is possible to get a bigger wheel in the same width and same offset. Therefore my answer and nicks answer would suffice. The whole offset/width debate is not restricted to just bigger wheels!

But thats not true something does happen! Its not better and its not worse but something does happen. Its just different and you have to get used to it!

But if you go bigger then not everything is constant the tyres are lower profile! That is the only thing you can guarentee on bigger wheels

Do you think this is how they decided not accept the Euro?
Yeah, like me shouting "NOT A F*CKING CHANCE, MATEY!"Quote: Originally posted by BenR on 10 June 2003

Oooh, young man!
This is a nice geometry setup!
How do I make it look like that on my 16v?

I would put them away in your garage nice and safe were they cant be used. Seriously dont use spacers if you dont need them!
