Tire Selection Help with Kioti ck20 hst tires

[Littlehollow]

So I haven't had to change my tires yet on my Kioti ck20 and I noticed my front right tire looked a little low. On further inspection I noticed quite a lot of cracking on the outside wall close to the rim. I also noticed the same on the other side. I was able to fill the tire and it is a slow leak so I can still use it but I'm thinking I should just go ahead and replace them both. My question is that I looked up the size tire (Industrial front: 24x8.50-12/4) but where is the best place to order? I looked at firestone and the measurements seem different. Can anyone here point me in the right direction?

24x850-12 has been Discontinued. You will need to use 24x950-12.
