Important Questions & Answers about Motorcycle Tires

Questioning is part of human nature, especially when the questioning is related to a major investment such as a Harley Davidson. It’s important to have real answers to our questions. In the field of motorcycles, more specifically motorcycle parts, we have important decisions to make about tires. It is imperative that we all be informed before making these decisions.  Below you will fine six of the most common motorcycle tire questions and their corresponding answers.
 
1. What’s the correct tire age? The basic rule of thumb with motorcycle tires is that the newer the tire is the better the tire is. However, the age is actually of less importance when it comes to making a tire last longer. The best advice is to avoid buying tires that are over six or seven years old.  Be sure to check the date of when the tire was manufactured by searching for the three or four-digit number stamped in the tire’s sidewall. An example would be “2101” which stands for 21st week of 2001.

2. Are new tires better then aged tires?  New tires are better because the actual tire is an organic material that decomposes over time.  Also, the older the tire gets, the more it is exposed to outgassing. Outgassing leads to a more brittle tire.

3. What is the best thing to do in case of a flat tire?   Motorcycle tires flex from more directions then a car tire. Unlike car tires, motorcycle tires have only two tires working for it, so when one goes the bike will fall. For this reason, the best thing to do in case of a flat tire is to replace it as opposed to simply plugging it.

4. When is there a need for replacement tire? It depends, but it’s generally a good idea to replace your tires sooner rather than later. If tread depth is 1-2mm it is time to replace your tires. Also keep in mind that dry rotting or "cracking" usually means that the tires are old and/or the bike has not been in covered storage. If there is excessive dry rotting, you should get new tires.  Lastly, tires can cup or scallop when already having an uneven surface and when doing so they should definitely be replaced. 

5. What about size and pressure? Run the bike in the recommended tire pressure. A tire that is very under-inflated generates a lot of heat which can lead to a blow out. Tires that run too hot also wear out more quickly. The process is simply. You just have to stick to the manufacturers guidelines. That is the safest route.  However, on the other hand, you can have some deviations depending on your desired performance.

6. When to buy a tire? You can buy tires at reputable motorcycle stores. These stores have already established their names and services. You can also order online or with ebay.  But be sure to ask the right questions and view the proper pictures.  Also, make sure you have the option of returning them if, in person, they are not what you thought you were buying.
