Honda doesn't state a prohibition because the code of federal regulations (CFR) does.You ever hear of a person pulling a trailer who gets in an accident having an insurance issue? How about a trike rider? Or a sidecarist? Now take a look at pg 17 of your owner's manual. You will see Honda NEVER mentions a CT prohibition anywhere. However, they DO say DO NOT tow a trailer or add a sidecar. Yet for some reason, insurance doesn't have an issue with mods the manufacturer specifically prohibit.
Do the federal rules you cited SPECIFICALLY state do not use car tires on MC rims, like Honda specifically says do not tow or attach sidecars? Or do the federal rules only state something to the effect that those tires are OEM spec'd? I Googled the CFR you cited, but it is so convoluted, IDK how anyone can find anything specific in it.In the USA the DOT placards on the motorcycle and the owners manual specify M/C in the tire size. These placards on vehicles and printed in owners manuals are required on vehicles approved for sale in respective jurisdictions and in the FMVSS code and CFR 49.571 are specific descriptions of approved rims supplied on vehicles approved for sale and the rim type is M/C for motorcycles, hence the description of tire size includes M/C. It's on the sidewall of the tire as well.
ya its called lawlers bs!!!! Cover "there azz not yours = more bs.honda doesn't state a prohibition because the code of federal regulations (cfr) does.

I don't have a dog in this fight but it's clear that if in the event of a claim an insurance company could deny it based on the clause for unapproved modifications. Because this is uncommon makes the risk acceptable but it is a risk nevertheless.
https://www.law.cornell.edu/cfr/text/49/part-571In regards to CFR 49.571, dduelin has a point. If the correct Rims are specifically called out with tires sizes.
DOT approval is ALWAYS for a specific type of vehicle. There is no such thing as a car tire that is DOT approved for motorcycles. It would be the same thing as putting a passenger car tire on a 1 ton pickup.If its DOT approved you are golden.:smile2:
CFR 49 571.119 S5 to S5.2 sets forth the federal standards for tire matches to rims approved for certain vehicles sold in the USA. The federal governing body allows trade associations to publish the lists of approved rims for approved tires and one would have to have access to The Tire and Rim Association and the Japan Automobile Tire Manufacturers' Association, Inc.to see the specific dimensions, cross sections, and markings of vehicle category tires and rims but such detail is not required for this discussion. Suffice to say motorcycle rims vary from automobile rims in definite ways because they are both designed to meet different stresses under expected use therefore standards are set forth.https://www.law.cornell.edu/cfr/text/49/part-571
So far, this is the only working link to the CFR that I have found.
I found NOTHING under the FMVSS that prohibits a CT from being installed on a mc. If I missed it somewhere, please point it out. Standard 119 just discusses testing.
