Kumho KL71's come in 35" E rated and there is a difference between E and D side wall construction. These trucks are heavy and need E rated side walls.

 

Have you read the CFR's?

The blanket redneck statements do an injustice to people.

Define heavy? Rather vague statement.

Define difference in sidewalls? Rather vague statement.

Define any differences...pressure...load capabilties...etc?

Try to understand the on TRUE fact of all tires...regardless of size or rating.

THEY ARE EXPECTED TO PERFORM EQUALLY WELL THROUGH THE SAME SET OF TESTS AT THE RATED LOAD!

 

I'd be interested to know exactly what the tests consisted of, and the definition of the term "perform equally well."

 

I don't see anything "redneck" about his statememnt.

I'd like to know what "rated load" means.
All I know is an E rated tire is rated for a heavier load than a D rated tire, that's why I'd feel better with an E.

The Kuhmo LT315/70R17 are only D rated, the Nittos are 34's and I hear they wear faster than the Toyo's?

 

Just a WAG here, but if the test consists of running a tire at max rated load for 2 hours on a machine and it doesn't blow out then it performs equally well, then that's not saying much.

Just sayin'

 

I know your just saying...but that is the design criteria...they all use!

You understad...so help out instead of poking me.

Load Index D tire that is rated at 3200 lbs is no better or worse than a Load Index E tire that is rated at 3200 lbs...

I'd like to know what "rated load" means.
All I know is an E rated tire is rated for a heavier load than a D rated tire, that's why I'd feel better with an E.

False and False...

I have had several D tires with load ratings in excess of 3500 lbs which far exceeds the OEM 3200 lb E tire...

Load rating is the exact MAXIMUM load at the tire that is both legal and deemed safe by testing proceedures.
The kicker here is...the E was tested at a higher inflation pressure than the D.

Under that comparison...I would choose the D! Better ride!

 

Is a 10 ply tire really 10 ply or just 10 ply rated???

 

I think load ratings are just one of many factors that should go into a tire purchasing decision. That's where the problem lies - just focusing on that one thing, then the tire doesn't perform as expected for whatever reason, and blame the load rating.

For example, you get a bigger Rage D tire with the same load rating as the smaller E tire. But maybe it can't perform under certain circumstances because you are trying to haul heavy. Maybe it rides nice unloaded and that's what you drive most of the time. But you could be seriously compromising your hauling performance/safety due to inflation/heat/sidewall issues. There's always going to be some compromise involved. Gotta factor everything into the choice of tire.

..will not always be true for every application in all possible scenarios.

 

I have the toyo at 285/75/17 on my 2005 has the kore leveling kit they look great.

 

Agreed...

For the record...I have (2) OEM Tire'd Dually's, one SRW with 35x13.5's and one SRW with 37x13.5's. All of the trucks have regularly grossed 25-30k.

I kinda like my 37's the most. It must be one heck of a tire to beat TWO!

 

Shorty, those are only ratings going back to standards set in the old days.


CQ, if a guy wants to get the best tire for carrying a heavy load would he be better off getting:

A. - an E rated tire with a load rating of 3640 lbs at 65 pounds (Interco Vortrac 35x12.50R17LT)

or

B. - a D rated tire with a load capacity of 3000 pounds at 50 psi? (The Pro Comp XT AT 35x12.50R-17)


<EDIT>
I have 285's now on my non leveled truck, IMO they'd be too small for a leveled truck.

CQ, you have 2 SRW duallies?

 

You got me wrong...or I got it wrong....

I have 4 trucks...

08 3500 DRW Chassis Cab with a 11 beed
04.5 2500 SRW QC 4x4 with 35's
04 2500 SRW QC LB 4x4 with 37's
04 3500 DRW QC

Go with the vortracs...in thyat case...unless somebody has something bad to say???

You really don't haul/tow that much...and I was just vouching for XAT's as a darn good tire.

Load H 19.5's would be the way to go...heck 21's even...but we all do more than just tow/haul.

 

I would not be worried about a good D rated tire, I usualy run E rated tires but my studed snow tires are D rated and I tow and drive like cquestad. I have many miles where my CGVW has been 18k-30k and have had no problems. I am also going to go with the procomp X-AT's when it is time to get these snow tires off. If you want more E rated choices in a bigger tire go with some 18" or 20" wheels.

 

Nitto terra grappler makes a 305/70R/17 E rated tire rated to 3640 lbs. so it's not 315 which is about 35.4" it's only a 305 but comes in at 34.6" My BFGs are almost gone at 42K and they were a bit soft so I found these and think I will try em out. I was not that happy with the BFGs at least one of them was a bit out of round or something, just enough to bug me.

34", it is an option though as well as the 285-75r17 Toyos which are also 34" (more or less)

I've heard Toyos and Nittos come from the same factory but also heard the Nitto's don't wear as well but seem to be cheaper.
