Ratsno1,
Welcome to the community.
You ask a tough question there... One we will not be able to give you a 100% accurate answer on.
Contacting Honda you will never get the response you are looking for and continued pushing may leave you with one word.. "denied".
Though many dealers will not take into consideration tires of 1 size larger. Say 26's. But if you get into 28+ then they may.
Many people keep there factory tires/wheels just for this reason, or borrow a set from a like machine when taking it in.
