weight rating coincides. the tire squish is the footprint..could be flat footed and as hard as a T-rated at the same time. I have learned this recently. I have t-rated that looks to have gone thru h*ll, random tire deflatings, by nature..the whole time it was the weight rating...on extremely hard tread that could last the torture forever.
the two digit number .. if AWD, half the weight of the car on one tire is a good call. I need "91" for an old sube with lockup diffs, as example. The FWD machines get away with just about everything but longevity. A good weight rating will help make a stiff ride, as it does not need as high one. And then there is the brand name game..are you really getting the rating written?
