I've had spoked wheels for years.  I plant all my beans with the planter into corn stalks.   Maybe once every other year I'll plug up a wheel with stalks but before I had spoked wheels I was plugging up wheels with mud all the time on wet years.  CIH has a bad habit of letting the mud come up the back of the tire and stay inside the rim.   Spoked wheels eliminated that problem.  I was on the verge of switching colors because of the constant plugging with mud before I went with spoked, especially when I planted into bean ground.   I'll put up with an occasional corn stalk problem.
