I think the skinny tires he is talking about at the 35-40-45 aspect ratio tires. Such as the 295/40R20 which is also on a 20" rim, it's load is only 2601 lbs 285/45R22 which is on a 22" rim, It's load is only 2601 lbs or the 305/35R24 which is on a 24'' rim, It's load is onlyu 2469 lbs These are all considered Low Profile tires for Larger SUVs and not really designed to carry a load. Any of the tires in a 65/70/75 aspect ratio are considered truck tires and can handle the loads if rated in the appropriate load range. The cavat here is the folks who buy floatation tires. The tires designated at 33x12.5 by X rim size. or the 35x12.5 by X rim size. These tires while rated at 10 ply and E rated still run at 65 psi and their load ratings are considerable lower than the metric truck tires of similar size and laod capacity |
