OK for the rubber, friend of mine used to run a car tyre on the back as his story was the bike was so low you could not ride it round a bend you had to be careful,less than 4 inches, ( car tyre much cheaper than moto), on the front was a silly thing like from a drag rail but close to a bicycle 26" needless to say he had many problems with the police and its conformaty to legal requierements again tyre a such a small price.

The bike lasted 8 months before he lost his licence, and as he was a rebel kept on using it till the judge told him STOP or HOLIDAY CAMP with full board, car tyre went back on his dads car, front end went on his younger brothers Bicycle with a stupid springer suspension, and the engine went back to a Triumph Bonneville. It was a strange thing but in 1966 you did it with what you could BEG, BORROW or STxxxxxx have on loan for a permenant basis.

I like the map idea to show your test route, 20/20

 

Keep the Grey coming long and slow

Hey Albert! Well I've always been a little on the odd side so I was easily drawn to the Dark Side. The car tire on the back just looks bad ass! Since our bikes have such limited cornering clearance you can't use all of a motorcycle tires tread anyway so I figured what the heck! The grip on the car tire is greater than a MT tire especially in the rain or on gravel roads. Running a rear MC tire on the front, mounted backwards, offers a tire with a deeper tread for greater mileage and in my case a super sticky triple compound sportbike tire for superior grip.

Crap! forgot the photos

The wrinkles are on both sides but I can't lean the bike over far enough where they would contact the pavement so I'll just keep riding and see what happens.

Wow! Great story Beaerkiller! Very interesting set-up!
