dave you dont need a trolley for holland mate its easy fishing no long walks or is it for when your micked in the shamrock is your mate going to take you home on it  not long now kid!!!!!!!!!!!!!!!!!!
You can just buy a new tube for it....Halfords do a wonderful range of sizes(you'll be surpirsed), and I got some for the little ones pushchair the other day that were pretty close to being the right size for my trolly....I must admit I didn't think that I'd find any that would fit, but sure enough they were stocked on the shelf.
Dave mate that foam breaks down within a couple of weeks, I don`t recommend it at all for fishing! Great for punctures on bikes though, will get you home from three mile away. I carry two on my bike.  Think I`ll try Halfords, I`ve got a puncture too! Have to blow tyre up on way to and from canal!!! [!]
I brought going back a number of years a rubber/soft plastic inner tube protector. Its a flat flexible material that goes around the inside of the rubber tyre between the inner tyre wall and inner tube. Once fitted I have never had another puncture. Wonderful little bit of kit
