Trikes: Air filled wheels?

[cheekyginger]

Has anyone found a trike that has air filled wheels. A few of my friends have them i the hard plastic wheels wouldnt be great for the off-road paths near me.

Any ideas?

Ds had a Puky one with air filled wheels. They are a little pricey I believe though my db bought his.

It still looks ok though despite being left out in garden for a year or so and languishing unused in the garage for another couple of years.
