I have the same problem. Only with 13" tires. I just got a new trailer to build a teardrop on and would like to run car radials. But have new trailer bias ply to use up.gudmund wrote:Car tires work GREAT on Teardrop Trailers!! 'Trailer' tires are OVERKILL on teardrops!! the stiff sidewalls were intended for 'top-heavy' big trailers along with the hi-pressure load capacities which are the reason they are 'limited' to the 65 mph speed limits due to their heat build-up during use when loaded. On teardrops they ride rough being 'there is no load per say', yes lowering the air pressure helps some but being the trailer is so light in weight, I have found car tires work (ride) so much better (or the LT for off-roading which trailer tire were not made for) As far as load ratings - one 'car' 205/75-14 I am using has the load capacity to carry more than the whole 'total' weight of my teardrop = 1400 lbs load capacity for 1 tire (my tear loaded has never been more than 1300 lbs total - usually my running total is 1100 lbs nowadays and yes I am a 'regular' user of my states truck weight scales after hours when they are closed being they leave the scales turned on) 2 tires at 1400 lb each = a 2800 lbs load capacity for a trailer base that is rated for a 2000 lb load max. This is my opinion from the experience of having used both (and now the kicker of 'my opinion' stated here is that I am now stuck again with trailer tires being the "brand new" teardrop I just bought a week or so ago came with them - I either use them 'as is' for now and wear them out or go buy new tires of my choice
