Front wheels too thin

THIS BUGGY IS DANGEROUS!
If you are considering buying this buggy to push around 2 children, this is not the buggy to buy, it would be a good design if the developers had understood physics and put wider wheels on the front, as it stands, the buggy becomes too heavy and the wheels block, get stuck on slight uneven surfaces, this causes the spokes of the wheels to crack and bend the wheels to breaking point.

The reason I say this is a dangerous buggy:
I have already had quite a few tumbles with both my children in this buggy, this has happened just casually walking on regular city pavements, taking the kids out for the day or to nursery, whilst pushing the buggy at a normal pace, the wheels get stuck and the buggy tumbles forwards and if you are not careful, you tumble over the buggy, VERY DANGEROUS for a pregnant lady, a weaker or elderly pushchair handler.

Please take this seriously.
