I have one customer that runs S155 Hysters all day over railroad tracks and pot holes. I went to a custom ITL (brand) tire with a TFT compound and man I havent had any issues. ITL and Maine tires are owned by GPX international - look them up.
ITL's come stock on all Cats and Mitsubishis and Maine comes stock on all Hysters and yales, GPX owns both of them.
If you have a decent floor run ITL with EL compound, or electric compound, it has less resistance to the ground so less heat buildup, less tire break down.
On pnuematics I use a ITL with a softtuff compound. In my opinion there is no better then ITL
