I'm going to buy a set of 13" radial tires, ST185/80R/13. The trailer came with ST175/80r/13. The trailer is 3300, load cap. 1125, tongue weight 350. It has two axles. 3300+1125=
4425 lbs minus tongue weight =
4075lbs
From what I've read I should get Maxxis or Carlisle tires and they are rated at 1480 lbs. 4x1480=
5920lbs
There is enough reserve in these tires.
1 I wondered if there were any 185 radial tires with pressure rating of 65psi instead of 50psi. Can't have too much tire reserve.
I'm not looking for more load capacity.
2 Should I get the Maxxis or Carlisle tires. They are same price but I had a string of blow outs with my 5th wheel and don't need that.
