First post, so i apologize for any issues if there are any. I recently picked up an old Craftsman LT-1000 and i have some new rear tires to swap to it, but the ones that are currently on it are rusted really bad and i cant seem to remove them. I popped the C clip off and try prying/pulling the tire off to no avail. Any technique you guys have for removing stuck tires like this? This and what all would you recommend to do with this mower for a beginner/first race mower. It has the 16hp koehler engine, 6 speed transmission, a 6.5 inch pulley in front, and a 3 inch in the rear. I most definitely want to do this project the correct and safe way, thats why im asking your opinions on this. I have a welder and most of the more basic tools required to do work on a mower like this i just am unsure on how/what else there truly is to do while still being reasonable in the price/amount of work scale. Any help is appreciated greatly!
