OK, so this is not a recipe, but like I said… this site is mainly for my use.
You should replace your tires at least every six years whether they are worn or not. They degrade. Even if there’s plenty of tread left, tires should be replaced if they’re too old. Over time, the rubber will dry and crack, possibly leading to a blowout or flat tire.
You can tell the manufacture date of your tire by looking on the side. There will be DOT followed by four numbers (eg) DOT and then eventually 1418. This means they were manufactured during the 14th week of 2018 which is about mid April 2018.
