Slicks Tread width

[Alan Roehrich]

My educated guess would be that putting them on a rim narrower than they were designed for would at the very least reduce the width of the contact patch. It may also cause the tire to be less stable with regards to handling.

This is kind of what i thought too plus being its a heavy car

I also thought it may cup the tread and require less pressure than usual so you get a full contact patch

I need to find somebody with a used 28" od and 10" tread width so i can mount it and measure

I gave up trying to run the widest tire possible on my 8" rims, and went to 9" tires, and it has worked better all the way around, (performance, consistency, tire life) for me.
Seems like what I should have been gaining in traction was lost with sidewall and tread section distortion.

I've always been in agreement with the theory that Alan mentioned. A wider rim should allow for more air pressure for better sidewall and top end stability while still providing a full "footprint". Most people I know run a rim 1" wider than the tire tread width.
