All those big pieces of ragged rubber on the side of the road? Those are retreads. Never put a retread on a steering axle. I used to dispatch for a small trucking company a long time ago so I picked up a few things about retreads along the way, that and spending my formative years in my dad's tire shop. When I started with the trucking company we used to buy a lot of retreads before making some changes to the tire program. When we changed up, we put in place the following changes. We ran new tires only on steering axle and were required to. We used only our own casings, tires were recapped no more than twice, after the second they went to Bandag. Steering were either KS or Goodyear, depending on size. All new tires bought, whether steerer, drive, or trailer shared, the same casing from the factory. This was key for us and ensured uniform diameter, which gave us the same sidewall flexing and uniform heating. We also settled on only one drive tread pattern and one trailer tread pattern, giving us uniformity in more than just appearance. After making these changes we stopped having blowouts and casing separations, which saved us a ton of money in road service calls. No retread/recap is as good as a new tire, that is a given. Buying retread/recaps utilizing unknown casings is a gamble, using unknown casings in a tire size regularly used in an abusive manner, i.e. off-roading is stacking the odds further against you. There are lots of ways to save money, tires that carry you over the road at high speed are not one. Buy new.
