I bought the heavy 4X8 and have a couple of questions about the wheels/tires. The supplied two-ply tires are rated for 55 mph maximum. Just how unsafe are they at 65 mph, when hauling only a pair of light kayaks (pre-teardrop configuration)? Does anyone run these tires with a teardrop atttched?
Also, I went to add some grease to the hubs and the grease fittings are not standard zerks. What do I need to do to pump in some added grease with these fittings?
Thanks for any advice for a total noob.
