Hey Brett,
I put turftires on my 226D, ended up going through Gary Jamieson in Eastern PA. The wheels he supplied actually came from a company here in Ohio. Very heavy and well build, lotts better than original. (the centerplate was made out of 1/2 inch steel)Drop him an E-mail, he might be able to help you gandgjamieson@direcway.com
His # is 570-253-4810
