driveability of a motorcycle with wide car tires



I am building a motorcycle powered by a car engine and I'm considering
using a car tire
......something like a drag bike with wide slicks at the rear wheel.

How is the driveability of such a setup?
I guess I'd be asking a question even before that one
- why?
Very, very poor.


I'm sure it'll work with straight roads but when it comes to the
numerous twists and turns around the country, I'm not sure if there
will any traction problems.
If you use 4 wheels there will be no problem!
Turns? You want this thing to TURN, too?

At one time, US motorcycle sales dropped so low that nobody was
producing tires for them, and HD produced motorcycles that used
automobile tires. There's an excellent reason they didn't continue to
do so any longer than necessary.

These guys love their car tires on their wingers. I wouldn't try it
myself.
I think you will be very disappointed. The bottom line is that cars
turn using the slip angles of tires while bikes turn using lateral
force on the tires (called camber thrust). For this to work, the
tread is curved, the sidewalls are MUCH stiffer, and there is even a
special bead used to mate to the rim (at least in tubeless radial
tires).

Motorcycle tires are very different and cost more for very valid
engineering reasons.

Also, as Timberwoof stated, drag bikes are completely different from
bikes designed to handle curves. You won't see MotoGP bikes with
wheelie bars, very low ground clearance, extended swing arms, and
super fat rear tires.
