SO.. ive tried calling ranger 3 times and left three msgs and no one has called me back trying to get some info about my trailer hard to explain but... this is what i have ranger z118 2011 single axle trailer and if you look at the tires they look kicked out some and wear heavily on the inside blew two tires last year didn't notice the tires looking kicked out and wearing heavily on the inside took to tire shop put new tires on and they told me axle and everything looks good... no way the trailer is designed for tires to not be perfectly flat/level is there???
