do you have to replace all the tyres on a c4 picasso if i damage one
Posted. Hi everyone, i just had a puncture this morning (G Picasso) and had to use the tyre sealant provided (was not told about the fact it did not have a spare). This stuff costs over 20 quid to replace, can only use it on one tyre (at least i could) and you can not repair the tyre after you use it.n the Citroenet website there is a very long article on the C4 Picasso.... (there is more than one, you need the one headed C4 Picasso, but dealing with the 7-seater; there's another dealing with the 5 seater).
