Some time ago in these forums there was a discussion of certain new higher weight-carrying rated tires that are available in "Load Range E" sizes.
I seem to remember that the discussions at the time pointed to the purpose of these higher ratings being to provide for four-tired (and hence narrow) delivery trucks that can be small overall ... but still be able to carry heavy cargo for use around cities. This being especially helpful in Europe now - but gradually being needed everywhere in high density populated areas all over the world - for material delivery by trucks that could be narrow for the streets and low to the ground for more convenient access at delivery sites.
My comments on these tires are:
1) Are these higher rated tires U.S. sourced? (Myself and some RV owners still prefer that.)
2) Of course a six-tired E450 or 4500 can still be fully served with six 2680 lb. tires, since 6 X 2680 lbs. equals 16080 lbs. total, and 4 X 2680 lbs. equals 10720 lbs. in the rear.
3) Do these higher rated tires carry more weight only with higher inflation pressures ... or are they able to do it with only 80 lbs. of maximum pressure due to stiffer/heavier material being used in their construction? Of course with heavier construction, the ride of an RV using them will have a stiffer ride at any given pressure.
4) If these tires are able to carry more weight due to heavier-duty construction, then they may be close to what I've wanted for quite some time - a "tougher tire" than the typical 10-ply rated Load Range E tire. In other words, a 16 inch rim/~31 inch tall Load Range G (12 ply rated?) tire for use on Ford E450 and Chevy 4500 based motorhomes that is more puncture-proof at 80 lbs. of pressure on down (the pressures used below 80 lbs. of course depending upon the weight of one's motorhome).
My goal is a more puncher-proof and blowout-proof tire - for both getting to/from rough off-highway exploring and camping areas, plus more safety from blowouts on the open road.
