What a tire weighs is an argument that is brought up here often. Weight has no relationship to durability or the ability of a tire to not puncture with a 3" nail. Any tire you run on a travel trailer will puncture with an 3" nail (under the right conditions) if it's either an ST or LT tire.

It's a bad argument.

I don't recall anyone saying that any tire can't be punctured.

What argument are you trying to make?

Read my post. A heavier tire is not necessarily a more reliable tire.

There is more to reliability and durability than puncture resistance.

Agreed. But the weight of a tire isn't one of them.

Once again I am going way out on a limb here, and saying something that is simply "opinion": I think when people quote the weight of a tire, the "implication" at least, is that that all things being equal ( same or similar construction materials ) it's difficult to make a "sturdy, durable, stiff sidewall, tough tread area" tire....and make it lightweight. So in the end, the tires that are built to be "tougher" shall we say for heavy duty use, end up often being heavier.

Now don't go all nutz on me here techno-folks ! I know that materials like kevlar can be used that are stronger and lighter, etc, and other cool stuff....... I'm just making an observation, that often the way the companies get toughness, is with "more material"....and therefore more weight. The flip side of that is that perhaps it's fair to say, that a tire that is thin and flexy in the sidewall and tread area may in fact be that way simply becuase they used a minimum of material.

"Opinion only....no engineering fact behind this post".:)

EDIT: the following is an example of where "thin and lightweight" is good: my motorcycles use Z speed rated radials. These tires are thin, and light. My understanding is, they need to be built this way to be able to shed heat sufficient to survive the "plus 149mph" speed rating. These tires are actually easy to mount and dismount ( I do my own mounting and balancing of the bike tires ) partially because they are so flexy. So this is a case where light and seemingly flexy is good. However, they don't have very high load ratings for their size either. Example, the tire on the back of the Honda is a 190/50-17, but only has a load capacity of 800 pounds at 42 psi.
Probably would'nt wanna use 'em on a trailer ! :)
