Converting a rear wheel to accept a car tyre.....

because 10 years for death by dangerous driving and no insurance, appeals to some people who in the good old days were locked up for everyone's safety
 
Can you explain why you’d bother?

Having the abilty to run a car tyre interests me mainly because of the difference in wear rates between motorcycle and car tyres.

There is a huge difference between an average of 6000 miles per tyre and 35,000 miles per tyre.

Not all bikes are ridden primarily on twisties or off-road.

Some bikes are ridden exclusively on autobahnen, autoroutes or freeways although to read some peoples replies, (those completely lacking in imagination,) it would seem that because they would prefer to drive a car on those type of roads, everyone else should as well.

It interests me that a number of people in the USA have converted their bikes to run car tyres at the rear covering many thousands of miles in the process and without any problems.
 
How many miles a year do you actually ride ?

Well, it seems to me to be a bad idea for lots of reasons, all of which have been discussed above, and I’d want some convincing of the “without any problems” assertion. Some bloke on YouTube is not evidence.

I spent most of my career designing and developing bits for cars & vans, and I know quite a lot about the process, and a bit about the rules & regulations. If you go off piste, you’ll be ignoring the collective wisdom of those who do design vehicles and their components professionally. You might be able to take the theoretical approach, and carry out the extensive testing to confirm it, and come up with a solution that gives you a massively enhanced mileage from your tyres, but I doubt you’d want or be able to spend the millions and years doing that (and it would eat any savings many times over). In short, if a tyre manufacturer thought they could sell bike tyres that lasted 35000 miles, profitably, they’d do it. It seems however that most of us do not prioritise mileage over performance, handling and safety.

And if you get away with it, that’ll be great, and if you don’t, you’ll wish you never tried.

I agree with the above.
People who say they'd be ok on an autobahn etc, a question, have the autobahns now been made perfectly straight without any camber whatsoever?.
A bike tyre is the way it's designed to allow the bike to lean over to negotiate a corner. It also as it is round will adjust to the road camber to help you ride in a straight line.
Putting a flat car tyre onto a motorcycle with remove these characteristics. I've not tried it but I'm sure it will also hinder it's ability to go round corners safely.
Even going round a corner to enter a slip road could end up being dangerous. I'm sure the bikes ability to lean over will be severely compromised.
Let alone the lack of grip from a tyre designed to last 30.000 miles on a car, which I'm sure will wear out much quicker on a motorcycle anyway. The car has 4 of them🫣
 
The car has 4 of them🫣
Which means they dont have to deform like a bike tyre to have a footprint
Watch the TT slow mos and see the tyre deform - without that deformation = no grip just sideways slide - a car has an opposite tyre to prevent that ( in most normal situations)

One of if not the most stupid ideas I have ever seen floated on these hallowed pages
