Need New Trailer Tires

[amateurfishing]

This is a pic of tires I currently have along with info on them, can anyone plz chime in on what this is in todays standards, I have no idea how old they are but seems like 4 bolt is difficult to find (for me)

B78-13ST

Load Range G (I think)

4 bolt rim

Max Load 1315 lbs. @ 50 PSI

I have a different tire on each side but both say same info, the cracking is getting real bad on sides and I just want to be prudent b4 murphys law takes over.

I don't know if I can get bigger tires than these even though max load states 1315lbs each gross trailer weight is 3,000lbs. would like to hit that mark with tires if possible just to be safer.

thanks for any and all

trying my dangest to get photo posted of current tire but something is not working here.

Take a lighter to it. Plastic will melt, organic will burn

did not touch it, afraid it may have been something to do with axle and really did not want to discover any more necessary repairs this week

That looks like fish line to me, take it off. Also take the hub off the axle, it could have got into the bearning or ruined the seal.

To answer your question, no it's not something from the hub, seal or bearings.
