I want everyone to know this: Don't just go out and buy a car tire and put it on the rear of a cruiser.
Talk to those who have tried it and listen to what they have to say. There is much to know, and much that you need to know before you go and buy your car tire. The Darkside Forum is busy developing a database on DS tires for all makes of bikes. There are tires to use, and tires not to use! The wrong choice could prove to be a DISASTER, while the correct choice may put a smile on your face. I have been factual to the best of my knowledge on any information I have and will present on DS tires. I don't want to see anyone get hurt using a car tire.
Some tires mount at lower seating pressures than other tires, the DS Forum has info available, it is important. All car tires need to be broken in, it takes about 500 miles for all of the components to start working together as the tire was originally designed per the manufacturer. Precise tire pressure settings on a DS tire on a MC are crucial, I am adamant about that. The tire I run on my Liner is an excellent choice (General Altimax HP) @ 40# PSI, and the same tire is absolutely squirrely at 30# PSI.. DS tires, we have learned, have this innate ability of keeping the tread on the pavement if the rider is knowlegible enough to know at what pressure to run the tire.
If all of the safety procedures are followed in mounting a car tire on a cruiser, you can have a safe machine that is enjoyable to ride and get superior traction wet, dry, on the straights, and thru the twisties. If you don't know what you are doing, ask those that do, or stick to the MC tires. DS tires are not for everyone.
We will never see DS tires on racing bikes, the lean angle is too great.
We will never see DS tires on a cruiser by a manufacturer ... regardless they will always make more money selling MC tires.
I hope everyone will take what I've said here as coming from what I've experienced and others have experienced over the years. Yes, I am an avid Dser. I've made effort to be straightforward, and help everyone have a better understanding of what running DS means.
Thank you, Max (BIGFOOT)
