Frequently Asked Questions

Q: Will these wheels fit my John Deere Z355R zero-turn? A: If your mower’s front caster tires are marked 9x3.50-4 and share the same bearing bore, these wheels should fit; always check the existing tire sidewall to confirm.

Q: Are these completely flat-free? A: Yes, the tire is made of solid polyurethane foam and contains no air, so it cannot go flat no matter what you run over.
