![]() R stands for radial (which is most tires today). Basically the bigger the number here, the taller the sidewall. The third part of the code is the aspect ration which simply means the percentage of the height to the width of the tire. The second part of the code (225 in this example) is the measure in millimeters from sidewall to sidewall of the tire. So you should look for LT or ST for your trailer. LT (Light Truck) and ST (Special Trailer) tires are typically used on trailers. They aren't designed for trailers and if you put them on a trailer you can't go by the load capacity on the tire. It's never a good idea to use P-metric tires on a trailer. P at the beginning stands for P-metric (or passenger car in the US). This is the type and size designation of the tire. Most folks are familiar with something like P225/70 R15 on your car. They all give you some information about the tire itself. There are a lot of numbers/codes on a tire. So lets talk about two topics related to tires: how to tell the measurements/size you need, and how to tell how old a tire is. So trailer tires are more likely to dry rot before the tread wears out. Also, they sit a lot when not being used. The first thing to understand is that trailer tires take more abuse than car tires due to trailer bounce while driving. But there's a couple things you need to consider with tires whether you own a trailer or are looking to buy one. You always want to go through a checklist before a trip. There's a lot to be said about tires for campers.
