Front tire

I have a 2000 Yamaha Venture with a Formula II sidecar.  Front not modified.  The stock front tire is a 150/80 16.  Many of us put on a narrower tire for better steering at low speeds.  I had to replace the tires when I put on the sidecar and went back to the stock.  Due for new ones and was wondering if anyone has tried a narrower tire on the front and if it mad steering easier?




I would rather have the widest tire I can get up there to smooth out the ride and give the best traction possible

I run a rear tire on the front and find it to ride much better than the stock size

just my personal opinion

I'll put my 2 cents in here... Regardless of the tire you run, the biggest improvement one can make for ease of steering is to modify the front end. Either changing the triple tree or add leading links. Triple tree is less visible, either are like adding power steering to an old truck in the difference they'll make. My bet is that Jay at DMC can help in that regard.

agreed 100% best investment I have made for my set up

The wider tire on the front will increase steering effort. May not be what you would want on an unmodified front end. If you go smaller make sure it still meets your load requirements. It likely will also be smaller in diameter, so you might have to adjust the lean/toe in. You won't really know how it works for you until you try it.  What works on one guys set up doesn't mean it will work on yours.  Too many variables.

When I got my rig it had 400x18, 100 series flat profile tires, front and rear.  I went to the stock motorcycle tires for my bike, which are a 90 series.  There was about an 1" difference in diameter which affected the gearing of the bike and I had to adjust the car to compensate.

Just a couple of things to keep in mind.
