I've done this to several cars with major improvements every time, tyre roar is a big problem.

First place i'd look is under the probably plastic or maybe thin carpetted section covering the rear wheelarches, a dickens of a lot of noise comes from there, then under the boot covering and rear seat and around the spare wheel if lucky enough to have one and up the sides of the inner rear wings.

Pound to a penny there's minimal if any insulation there to speak of, if you get those sections insulated well you'll probably be able to work out easier where any further noise is coming from.
Bulkhead and front arches and under passenger floor tend to be well insulated on most cars, but by all means have a poke about, if its not in place put some in.

If you get down a dirty with a good Merc Lexus etc you'll find all these areas already heavily insulated, the underfloor of my old pillarless Merc seems to be built of girders with rubber covered felt insulation around 3" thick between the joists, very quiet.

I bought self adhesive pads roughly 16" square from the usual auction site, best to get something destined for automotive insulating as it really should be fire retardent, underfloor covering and around wheelarches i used 8mm thick i think thicker the better, not that much space to play with under an Aygo, any heavier gauge would have been a struggle.

You can get quite carried away with this , much thinner panels for applying to door and bootlid skins.

Traditional underfelt fire retardent insulation can still be bought, much thicker, probably 18/20mm, i think it would do a better job but would be more difficult cutting to shape and would need glueing to hold on to upright panels, messy.
Maybe a mix of all types would be the best, heavy traditional laid on the flat and self adhesive pliable on the curved wheelarches and upright sections.

In the days of Exchange and Mart you could buy pre cut felt insulation for your chosen car, its not a new idea by a long chalk.

Go on Photme have a poke about and see whats there or isn't, but take a tip, leave it till the weather warms a bit, French plastic clips do not like the cold and many will break annoyingly, i have no idea what Hyundai clips will be like.

Its well worth doing especially with modern elastic band tyres which make a dreadful noise as well as offering no shock absorption whatsoever.

Thanks i will look in to it, have printed the above to remind when it gets warmer
