on my trailer. I get maybe 6 (if that) months out of my rear tires on my tandem axle enclosed. Tires are inflated properly, they just get too much scrub from all my tight turns in small neighborhoods. I got 3 years out of the front which to me is good enough. My question is should I get radials? will i get more life out of them? Is the price difference worth it? I get bias ply's for $55 a piece mounted. I don't wanna kill a set of say Goodyear Marathons and get maybe only 2 more months out of them. I know I will get a better ride without flat spots and that sort of thing but I don't care too much bout that. Once again its for a tandem axle enclosed trailer that weighs only 4500lbs with everything in it. If you don't know what your talking about as far as tires, please save us all from reading your BS and just don't post. Please!
