Does she have an attractive single sister?

 

Well Sir, No she doesn't I'm sorry to say. She did get a kick out of your question tho.

 

I'm not a big fan of the Load index myself. A D rated tire saying in can carry 3197 pounds the same as an E rated tire? Did I read that correctly?


When I bought the 2002 2500 it had D rated tires on it and loaded or just driving the thing handled like I was riding on four sponges. Upgraded to E rated tires and it was so much better.


I can't remember what a D or E rated were rated for before but don't think D's were rated for that a few years ago were they?


Oh well, no concern now, got G's on the new truck.

 

Someone decided that they could get more out of an oversize tire if they marked it with a heavier load rating, simply because it holds as much as the stock size tire.

 

The 50 psi max inflation guide says plenty about sidewall integrity. Super for a 1/2 ton.

 

Load range D tires handle fine on mine. That said, they won't handle the full load these trucks are capable of.

 

Been driving on 315 D rated Yokohama's for years and towed my 32 foot 5th wheel over many bad roads, including some really bad roads in Mexico. Never had a problem and never had a flat wheel. Yes, there is a small amount of sway at highway speed under a very small set of circumstances, but when that happens, just slow down until I am past the road conditions that cause it. When towing I pump the tires up to max pressure, but with no load, drop the pressure to about 35 psi. Even with the rears at 25 psi empty, after driving at highway speeds for a long time, the sidewalls are cool to the touch. Wore the first set out and now on my second set of Yokos. They are quiet and comfortable.

 

Boss' 02 had a set of D rated 305's on it when he got it. The gravel and nails and plants around here perforated them.

 

I've been running these for about a year now and am pretty happy

Sorry if the pic doesn't come across

 

It would be interesting if you could swap out yours for an e-rated tire for comparison.
I follow behind a friend's truck with BFG 315's maxed out at 50 psi. The sidewalls bulge way out. His truck weighs 10,500#. Aired down in Baja he's experienced sidewall failure.
In defense of the D rated tires,I've gotten a flat on I-5 where the weight of my rig destroyed my E-rated Toyo MT. Caca pasa.
I'm running 285-75-17 Toyo AT2's now with great success, so far.
On my last '98.5 I had a near catastrophic blowout with Bridgestone D rated 65 psi 3305# rated tires. My load was 2650#/tire well within the load capacity. $3300 damage in seconds.
In light of my experiences I choose to go with Dodge's recommended tire rating.

 

Some may not realize the weight difference between a 5.7 gas and a 5.9 diesel. With all the extra weight of the diesel in the front of the vehicle, a D range tire meets bare minimum, and the forbidden C range tires, will wear quicker, heat up faster and go flat more often. Why play with disaster when one can enjoy the security of the E range tires that the 2500 is designed for.

bullrambler:

I agree with your assessment of the "D" versus "E" rated tires for our Dodge CTD Pickups 100%!

Good post Sir.

 

X2 I have had no luck with any D rated tires lasting more than 30K miles before they start coming apart. My E rated tires are wearing allot better.
