Hiya,
Not sure if this will help anyone, but I have been having a problem with my Quinny Buzz getting puncture's constantly!
This has been a nightmare when I have a boxer dog to walk twice a day!
I live in Middlesbrough and there is a company called Greentyre who specialise in puncture proof tyres and they have a tyre specifically for buggys, luckily because I live down the road I popped in and spoke to a lady called Lauren, her contact number is 01642223322 they where so helpful and fitted the tyres for free. Well worth a call, I got mine 2 months ago now and they are still going strong! x
