In the May issue of MCN magazine a reader asks attorney Harry Deitzler for his opinion concerning use of a car tire on a motorcycle, and the question of “cause” in the event of an accident.

His reply is that in a court of law, the ‘cause’ issue is really not relevant.
It does no good for a defense attorney to show the car tire did not contribute to an accident.
Car tire are not ‘recommended’ (by motorcycle manufacturers or car tire manufacturers), so the attorney starts out at a disadvantage.


From reading Mr. Deitzler’s column I know that representing a motorcycle driver in any situation the attorney starts out at a disadvantage. A bald (or low tread) tire adds to that disadvantage, as does a CT.
It does not matter if a car tire can be shown to be ‘safer’ than a MCT for a particular application, it is not recommended, and that tells the ‘whole story’, so to speak.
Safety and cause are not the issues, recommendations are.

I expect no lawyer, motorcycle manufacturer, MCT manufacturer, or CT manufacturer to recommend use of a CT on a MC. This has to do with money (profit) as well as legal responsibility, long before any safety concern.

For safety concerns, I favor asking the users. Ask those who have used CT for tens of thousands, or in some cases, hundreds of thousands of miles. I wouldn’t even guess how many millions of miles have been put on CT for MC usage. It would not surprise me if it is hundreds of millions of miles.

This brings me to Mr Deitzler’s comment “Quite frankly, I have to wonder about anyone who has sufficient disposable income to buy a gold Wing and then elects to sacrifice any level of safety to save a few dollars on a tire.”

In my budget a thousand dollars a year is more than a few dollars.
But, honestly, safety is more important than money.

Well money is not the issue necessarily. I don't give a fig about the tire cost. I do give a fig about the headache of taking my bike in, dropping it off, picking it up etc. Also, the tread wears down so fast I wonder if it does any good in the rain. A car tire really pushes out the water; our moto tires have very little tread in the center to begin with.

You said it wasn't because you're cheap, then you said it's not necessarily the issue, the very next sentence you say you don't give a fig about the tire cost. So, which is it?

My dealer just changed my rear tire in an hour.

Do a lot of ridng in the rain do ya?

I'm trying to discern what, if any, advantages there would be for me to run a car tire. [Other than cost]

I commute daily on my motorcycle, rain or shine, all winter too. The only days I don't are snow or ice conditions (and even then I have been caught riding when an unexpected snow or ice storm happens) SO, for me tire life matters. I don't want to schedule the times to take it in, I work six days per week and the place I take it wants to keep it overnight and yes I have tried three different shops all are the same! Tire changes are a headache for me.
Rain is no reason to take a car in my experience.

What kind of bike do you ride?

One shop will let me drop it off and pick it up four hours later.
Makes me wonder if a quick oil change/tire change place for motorcycles would be a good business, like Jiffy Lube for bikes.

Well my "weekend" bike is my Tbird and my commuter is a Yamaha FJR 1300. I expect everyone to jump on this and say "well you don't want a car tire on your FJR" and I probably agree. I have Pilot 2s on the Yamaha now and I think they will last longer than the stock. My Tbird Metzeler need changing at 7500 miles and that's the bike I would more likely consider car tire for. I have to maintain my son's bike too (I know he needs to do it but he's in college etc.) and all this maintenance adds up to a headache!

But confession time, I ordered the Michelin Commander 2 for the Tbird last week because you girls scared me out of the car tire! So let's hope Michelin is revolutionizing moto tire longevity!

I ran my Metzeler rear at 40PSI, and had it replaced Saturday at 6000 miles [nail] and the way it was wearing, I know I could've gotten another 4000 miles out of it.

I just wanted to know if a car tire is really "better", and If anyone here has tried it I would be very interested in thier feedback. The cost savings alone would not be enough to sway me.

I agree that cost is not the primary issue. In fact I think I am changing the Metzeler out a little early, but there is very little central tread. I don't know whether tread matters much in the rain but I am just playing it safe. But wouldn't it be nice to get 50,000 miles out of a tire? I suspect there's an element of herd conformity of engineering principles (does a cruiser rear tire really have to be rounded? Is the contact patch on the upsloping side wall of a car tire any less than the contact patch of a rounded motorcycle tire in a turn?)
