Hi

I've just changed my 16 inch wheels for 17 inch wheels and now

My car handles very poorly!

Is this do to the bigger wheel a or is it the tracking?

Thanks

Vauxhall specified many tyre/wheel combinations, lowering the tyre profile as the rim size went up to maintain the same overall diameter.

Have you got the right size tyre for 17" wheels, as specified by Vauxhall - you will notice the ride deteriorate due to the lower sidewall, is that what you mean by "handles" very poorly.

Big wheels and low profile tyres are for track days - and bling - for comfort get the smallest wheel with highest profile tyre.

Are the wheels the correct fitment for your model?

Fitting larger wheels with lower profile tyres is not guaranteed to "improve" handling. The tyre is part of the suspension and fitting a stiffer tyre to suspension designed for a more compliant tyre can deteriorate the handling. Especially if the car has plenty of miles and the suspension is worn as with stiffer tyres the suspension has to work harder.

Did you have a special reason for changing the wheels, that is, what difference did you expect?
