Yep, we're on the same page, Denny. The class the Tiger was running in the hill climb required "stock-appearing" wheels, no mags, etc., so I used the original 5 1/2" wide wheels and stretched the width out to a little over 8", then we ran some low-profile Bridgestone racing tires. I used a similar procedure to add 4" to the width of a set of wheels for a 4WD tractor-pulling Dodge truck. I rolled a piece of 4" flat stock to match the diameter of the wheel center and inserted it into a cut-apart rim. No speed or balance concerns on those rims because pulling is a low-speed sport. Those wheels ended up 12" wide!
