442,
I bought the same size tires, with the wide white walls as well. Only, I decided to go with a radial tire.I actually had to use tubes. My old rims just didn't want to hold a the bead from the tire. The tubes have worked out just fine. One of the challenges with a bias ply tire, is when the sit for a while, they develop a flat spot. It is should eventually, go away as you drive and your tire warms up. If it doesn't, I would contact Coker Tire. The communication that I have had with them has been outstanding. Hope this helps.
