However it raises one important question rarely discussed in any of the forums:
Does "2,680 lbs Single / 2,470 lbs Dual - LT-Metric at 80 psi" AS COMPARED TO "3,085 lbs Single / 2,975 lbs Dual - C-Metric at 80 psi"
mean -> for a given tire size between the two tire types that the C-Metric version is a more rugged/stronger tire?
i.e. That the C-Metric version has more plies? If so, if carrying capacity is not an issue ... should one use the C-Metric type tires if they wish for more puncture-proofness - as in occasional offroad travel with their Class C?
To me, yes...it means the Commercial rated tire is stronger and thus less likely to have a blowout. I think it is very important to consider that most RVers are probably not religious about checking their tire psi all the time. Many people are driving at 75psi or 70psi or 65psi and thus stressing the dually tires. Since the Commercial rated tires have much more buffer (~500lbs per tire carrying capacity), they are less susceptible to issues when the tires are not all the way up to 80psi.
Also, if you do get a flat on ONE of the tires in the rear, the other tire on that side is now carrying DOUBLE the load that it should. 4500lbs?? In that scenario, I'd rather have a stronger tire (the commercial rated one) to give me a better chance of not blowing BOTH tires and then driving on and destroying the rims as well.
Would anyone like to share the downside of getting Commercial rated tires at least on the rear? The cost (in my experience) is minimal. Personally, I haven't noticed a difference in noise or ride comfort. I see very little downside. I place a huge value on safety. Another way of looking at it...blowout vs non-blowout sure makes for a big difference on the day it happens (or doesn't happen).
Safe travels!
