C'mon man. It's just stupid to put a car tire on a motorcycle.

Its a bad choice Dude. You cannot traverse the world only going straight. There are turns, yes? Even pulling into the parking lot of your favorite massage parlor and turning can put the tire on the edge possibly causing it to slip. And on the straight highway there is lots of gravel and debri.

Were you able to follow the video until the end?

But I get it. Go forth and do it. Its still stupid

That has been proven wrong if you can believe a few YouTube videos on the subject. But everyone is entitled to their opinion. I once thought it a concern as well but most find car tires that have some roundness on the edges that must make the difference.

The video by racebrooks is very good. It says that the handling is ****, and the guy only put the tyre on an adventure bike. Only an fool would put one on a sports oriented motorcycle - unless they ride like a granny and don't like corners or leaning.

I don't know anyone in real life that has put a car tire on their bike, but the posts I've read over the years from those that have gone dark are pretty mixed - some think it handles fine and others hate it.

I have replaced several rear tires on my street bikes over the years and every time I have noticed a big improvement in the handling of the bike. They just seem to lean and turn much more effortlessly (look there - go there) when I replace an old flatter-centered rear tire with a new rounded-profile tire. Changing the front and rear at the same time is almost like having a new bike! Anyhow, I personally don't want to imagine a world where the center of my rear tire is always flat and I never get to experience that new bike handling by simply replacing the tires. Just my 2¢.

Whichever side you ride, keep the shiny one up!
Cheers!

I've consider a car tire simply because I'm forced to ride a lot of gravel roads where I live. I could never convince myself that it would be better in the long run. The other big draw for me was I could get a run-flat tire by going with a car tire. And I've had 2 tank slappers due to sudden and complete air loss on the rear tire. But even with that incentive I just never did it until I was forced to go to a trike or no longer ride due to physical disabilities. Now I have 2 car tires but that's completely different that what's being discussed here. My best suggestion is, if you have the funds, to try it and if you don't like it switch back. Finding someone that will mount a car tire might prove problematic though. I had someone that would but I just couldn't pull the trigger. It's a personnel choice in the end.

For sure. I usually replace both front and rear at the same time because of every thing you just stated so well. The "expensive cost" of motorcycle tires? I'll gladly pay to ride and have fun.

@CRU - yep, good video. (y) Apologies that I credited racebrooks instead of you.

Judge for yourself but I've watched these two vids many times and it appears to me that a car tire gives you a wider contact patch in curves than does a motorcycle tire. But you be the judge...

Car tire ( you might want to turn the volume off )

Well, I guess that begs the question as to why all motorcycle racers at the top end of the sport aren't using car tyres.

Is it a conspiracy by the tyre manufacturers just to rip off the masses of motorcycle riders? :unsure::unsure:

Looks like the tire pressure in the car tire video is lower than the mc tire video. I've read that many dark siders run about 25 psi in their tires, and that gives them a bigger contact patch when leaning through a turn. I'm sure if I lower my mc tire pressure to 25 psi that I would have a larger contact patch - but I'm pretty sure that I'd be actively looking for an air pump to restore the handling that I had before at 10-15 psi higher. Maybe if I was low-siding a lot (and I just hated to ride slower), then I'd be more interested in finding new ways to increase the size of my contact patch while leaning.
Again, everyone is different and what I like other people may well think is absolutely crazy. If you like your bike with a car tire on it, then good deal. I'm just thinking that I would miss the handling that I know a nice round mc tire gives me. Again, just my 2¢.
Whatever you ride, ride it and enjoy it!
Cheers!

Extra weight maybe and they are all about reducing weight.

No-one can accuse me of being one-eyed. Here's a vid of a Goldwing with a car tyre. Impressive stuff.


However I did read a comment that the guy eventually totalled the bike, and he hasn't posted videos for a long time now.

Found this - some posts by the man himself (if you read some of the comments - he's not everyone's hero....lol):

Wow! I wish I had the skills to ride a Goldwing on the Dragon like that! Of course I'd also need the nerve to do it too!
Haven't been there in several years but there were always some crazy-good riders at Deals Gap! Scary-crazy-good!
