Generally, golf cart tires last 2-3 years. Here are a few things that will help to prolong the life of your golf cart tires: 

Proper Ply/Tread - Make sure that you’re selecting the proper ply/tread for the terrain where you’ll be driving. For example, you won’t want to buy 2 ply tires if you’re going offroading.

Rotate Tires Regularly - Uneven weight differences between the front and rear of the golf cart can cause wear and tear. Keeping your tires rotated periodically keeps them as even as can be, thus cutting down on the wear and tear. This is best for golf cart tires.
