In another thread Shorelander Trailers was used as a reference for ensuring the correct car tires were used on a trailer. That info was given with an implication (to me anyway)they endorsed the practice. Here's a no BS clarification. <br /><br />I received a Shorelander's catalog in the mail yesterday. Their info about tires is a generic tire reading chart (seen everywhere) which includes all tires. A small section of the chart talks about load capacity differences between car and trailer tires. To summarize it they wrote to use the same spec tire that came on the trailer when new, which is a trailer tire. Here's is a reply to an email I sent Shorelander about using car tires on trailers. Midwest Industries makes Shorelander...<br /><br />=================================================<br /><br />Bill,<br /><br />We only recommend trailer rated tires for our trailers, car tires are not recommend for trailer application.<br /><br />Thanks,<br /><br /><br />Jeff Holmes<br /><br />Customer Service Representative<br /><br />Midwest Industries, Inc.

If I may add - <br /><br />ST tires are built differently to car & LT tyres. They have stronger (& thicker) cords/belts. They have added chemicals to combat ozone degradation. They have shallower tread depth. The tread is not designed for traction (drive) axles or steer. <br /><br />And here's the kicker, they are NOT designed to be used until worn out, they should be replaced on a timeline - usually 4-5 years.

I just replaced an old beat up trailer with a less-old, less-beat-up trailer. However, the guy I bought it from used passenger car tires on it. I can tell you that everything you read here about sidewall flex is true. My trailer bounces down the road like a basketball and even though the tires are brand new (still had the blue crap on them) I will be switching them out for STs.

And if you could see what the sidewalls are doing and could measure temperatures you'd get it done even earlier.
