Which tire should I use?
We suggest that the poly-wheel used on the Tiger Trax be used when there is a firmer surface involved. If any other conditions are present then we fully recommend the 21” balloon tire that is used on the CatTrax. It is a 2 ply tire which gives it flexibility and strength.
Do I need hull cradles?
First we would suggest you contact the mfg. of your boat to see what their recommend is. If they say yes then that’s your answer. Our opinion is if you don’t need them then you don’t need them. That is to say that we have always found it easier to load the cat on the dolly without the cradles. Just pull back on the securing lines and walk the dolly under the boat. Now that might cost us some cradle sales but it’s our opinion that it is easier without them.
I have an old set that has uses a needle valve. Can I replace them?
Yes. That is the “old” style that has been replaced. We now use an aluminum rim with a Schrader type tire stem. You would need the newer tire and rim assembly but would require no other parts.
