Jim: It is much too muddy (5 plus inches rain last week) to go out to the farm and look to be sure. But, I am pretty sure I have a pair of 16.9x34 tires out there on rims. Do you need 20x34 or could 16's work? Wayne Snelling Assistant Professor Computer Information Systems South Plains College Lubbock, TX 806-747-0576 ex 4692 806-292-8412 cell
