Can I get foam fill instead of tubes?
While we do not carry this wheel assembly with a foam-filled tire rather than a pneumatic one, if you already have this wheel assembly, you should be able to replace the pneumatic tire with a foam-filled one. Just make sure that your rim can split - there should be 5 bolts holding the two rim halves together. If yours has those 5 bolts, you do have a split rim and can try our foam-filled 4.00-5 tire which is item# T05-901. If you try it and it doesn't work, we do have a 60-day return policy for items sent back in new/unused/undamaged condition.
