they are 13" wheels that i am running on it, and i have electric brakes on both axles. i am guessing my trailer probably weighs in between 1000-1500 lbs, and that my camaro weighs in around 3400lbs (its pretty stripped), so a tongue weight of about 500lbs would be good then. next time i load it up i will do that, i saw some points on my trailer that could use improvement so i am going to reinforce them first though

 

That's exactly what I did.
