Is it necessary to only by tires for T.T. Why can't I not buy regular tires for my T.T? Reason I am asking is that its seams that I am getting flat tires too often, 2 in one year. is that normal? This tires are fill with nitro air which I fill they are full of it. you get my drift.Thank you in advance..

The tires you put on your trailer MUST be rated to carry the GVWR (gross vehicle weight rating) of you trailer.You should not use "regular" passenger tires on your trailer.I doubt you can find LT (light truck) tires in the size (I'm guessing 14 or 15 inch wheels - probably ST205/75D14 ) that are on your trailer....so you will have to stick with ST tires.Most all ST tires are made in China and have a shaky reputation.Many of us have had good luck with Maxxis 8008 tires.and yes...nitrogen is pretty much of a hype.

You can't and should never use passenger car tires on your RV!Try some Maxxis tires like suggested and don't worry about filling them with anything than plain old air.

No to anything other than the original ST tires or LT tires along with appropriate rims. You might want to go up one load rating (LRC to LRD) and use better quality tires.Most travel trailers come with ST trailer tires and it is critical to stay under 65mph and to keep them inflated to the correct psi at all times. Ignoring either causes overheating of the internal tire structure, irreversible damage and will result in tire failure. Avoid potholes. Stay off shoulders where you could pick up something that will cause a puncture. What is the weight of your TT versus the total tire load rating? You want a 20 percent or more safety margin but some manufacturers load them up close to their rating. The weight can vary from side to side too which can unknowingly overload tires on one side.Are you having punctures, "blowouts" or tread separation? In the occasional case, the axles can be bent (owner caused) or misaligned (factory caused) causing uneven tire wear and eventual failure.Many RV owners use a TPMS to monitor tire pressure in their RV. Some (like me) check tire pressure on each leg of a trip before heading off. We have made in China Goodyear Marathon load range "D" tires with 10,000+ miles on them over 2 season with no problems - factory normally installs ChinaMaster LRC tires.Lots of excellent reading on this blog by a former tire engineer.

There's more info on this and other forums about tires than you can read in a day; just search on "tires" and you'll be overwhelmed. Briefly stated, some heavier FWs are coming from the factory now with LT tires. But, unless you have 15 or 16" wheels now, you may not find an LT tire in your size, or you may not have space to go to a larger wheel and tire. The alternative is to get the best ST tires, which most people believe are Maxxis. OTOH, they too can blowout. Treat your ST tires well: don't hit curbs, keep them at max PSI all the time, don't bother with nitrogen (sales gimmick), don't go more than the speed rating (usually 65mph) and expect they may not last more than three years.

What is flattening your tires? Nails, screws, or what?I have good luck running E rated tires. I've had tires delaminate over the years and several trailers, but no flats or blowouts.
