polyester contributes to a smoother ride and no flat spots on a bias tire right?

nylon is much stronger than polyester tho, correct?

and bias belted is a bias tire with steel or poly reinforcing belts under the tread, right?

i noticed that interco is making polyester and nylon swampers, and i'm wondering of the nylon plies would be tougher than the polys, at the expense of flat spots (who cares tho, they go away in 5 minutes).

bias belted is available only on SX and thornturds tho, so i want to stay away from that.

i don't have a short answer for you but 4WD and Sport Ute mag has an article explaining all the different types of tires and rims this month.......it has a white cruiser on the cover gettin it.
