FTX Front Buggy Wheel And Tyre Set White - Vantage
Although these wheels are not known for their strength, I haven't broken any yet. Maybe I have just been lucky, or maybe they have improved the quality of the plastic - I don't know. The tyres on the other hand are rather good, nice and grippy on grass and gravel, with reasonable wear characteristics. Just be prepared to reglue them - the factory glue job isn't great.
