Need more load rating than: Michelin LTX/MS2, LT265/70R17, 118/121R, 3195# @ 80PSIG

[WalterJ]

Maybe wife is hiding her rock collection in the RV, but regardless, anyone suggest or know of tire with higher load rating? We're seeing outside edge wear running RV @ 90+ psig.



Thanks for watching.

Nitto Duragrappler.

Are you looking to stick with the same size tire? A 285/70 or 285/75 will gain about 400 to 500 lbs per tire depending on manufacture/type. Isn't 90 psi above the max recommended pressure for those tires?

What is the weight on your rear axle loaded? Being those are stock sized tires and your having wear issues, increasing the tire size may not be the solution.

Have you considered 19. 5's?

1. Weigh truck and trailer axles independently. Get real numbers, compare to truck, trailer and tires specs.
2. I'm always a fan of an infra red thermometer with any tire concerns, its not so much the specific numbers as it is variations and extremes.
3. Increasing one spec does nothing for the other "as issued" specs.
4. Get a copy of the Long Long Trailer with Lucy and Desi, force better 1/2 to watch it with you if you both don't start laughing, well not much hope.

Passenger car tires are rated with a maximum, do not exceed pressure on the side wall. . most light truck and all truck tires are labeled with a load rating at a specific pressure, and that most likely isn't the maximum pressure... to find the maximum pressure go to either a tire data guide, and/or the manufactures web sight... the chart on the manufactures web sight will give you the pressure for the load...

Usually outside edge wear on the tire is under inflation for the load... I personally run 19. 5" tires and used to tow a work trailer that often would run to 20K lbs... my 5er is a tad under 15K. . I've been getting 90K miles on a set of 19. 5" tires and at this point have not had any flats or blowouts...

Thanks all for your input.

--My rear axle load is: 2200# tongue, + 400# full aux tank
--I've tried running 90+psig to help alleviate this apparent underinflated symptom when towing, to no availcold

--regular tire rotation & alignment chks biennually.
--3195# tire load max. rating I find is typical for all USA, LT truck tires, E rated, except possibly NITTO?
--calls to manuf's resulted in identical reports of: "All we can recommend is what the vehicle was equipped with OEM. "
--the Michelin 285/70 is strangely rated as a 'D' load rating, no help there

Further data mining resulted in:
--Nitto Dure Grappler sku 205-070: LT285/70R17 E 126R, OD=32. 80", 3750# @ 80PSIG
--Nitto Dure Grappler sku 205-370: LT285/75R17 E 128R, OD=33. 86", 3970# @ 80PSIG

Now 2 quandaries emerge:
1-Did Michelin alter their design 5 years ago, resulting in current evidence of lower than advertised load capabilities? I'm making a warranty claim, if only to determine what's changed. My maintance records are pretty good.

2-Is Nitto for real, or just Dura Grappler hype? I'll be posting this forum to hopefully find some real world experience using Nitto highway tires.

I was rotating my tires lastnite and washing wheels when I discovered my wheels say 2600lbs @ 80psi , I thought that was kind of low especially for a dually. What are the single wheels rated at?

 

[STEVEBROOKS]

Previously read this thread, and just logged it away as FYI. Since then I ran across a deal on a new-to-me, pristine 5th wheel toy hauler that was just too good to pass up and would have slipped away within a day if I hadn't bought it, so I did. Now, this thread applies to me as well. As I know it at least, conventional wisdom has been to have the same size tires on the back as on the front. I have like-new 265/70R17 load range E tires all the way around, but wonder if I can put two of the 285/75R17 Nitto Dura Grapplers on just the rear to gain some load capacity margin.

Has anybody done this too? If so, what were your results? Thanks in advance for the replies.

Steve

 

[CKelley1]

go to a G rated tire and run at 100 psi

 

[AH64ID]

245/70/19. 5 LRG 4540 @ 110 psi. They are my next rubber purchase.

My dad runs the Durra Grappler 285/75/17 with his slide in and a RAW of 7500lbs and they work great. No excessive bulge, sway, or tire heat.

Thanks for the replies. I'm aware of the 19. 5 tire option, and that's the direction I'll go if the "Dura Grapplers on the rear on the stock rims" one isn't feasible. Will there be any issues to running 265s on the front and 285s on the rear?

You cannot mix tire sized on a 4wd, it's possible on a 2wd but still not recommended.

 

[cerberusiam]

Other than blowing up the t-case if you ever use 4x4, not really. Cannot do that on a 4x4 and retain the 4x4 feature.

On the verge of taking the 19.5 inch route. Before doing so, would like a couple questions answered from those with experience:

1. What fitment issues (front and rear) occur when using 285/75s on a stock ride height truck? Currently, I run the stock size 265/70s.

2. What size tire, when using a 19.5 inch wheel, comes closest to the diameter of the 265/70s? What brand tire in that size, and hauling a heavy 5er, has anybody had good success with?

Thanks,

Steve

 

[AH64ID]

The 225/70/19.5" tire is slightly taller than the OEM 265/70's, the more popular 245/70/19.5 is a 33" tire.

A 285/70/19.5 is 35.4" tire.

I have a 2004.5, 3500 SRW. I run the 285 TOYO MT's when I am just towing my boat. When I use my slide in Artic Fox 1150 Camper I switch to my set of 19.5's. They are the Vision type 81 with a set of Michelin XDS2 245/70R/19.5. To help handle the load I use Timbren Helpers, Heavy duty shocks, Road master sway bar and a 42 inch stinger for the Super Hitch so I can tow the boat.
My weights are:
Truck/Camper/Boat
Front: 4600 lbs
Drive: 8800 lbs

Truck/Camper
Front: 4850 lbs
Drive: 8100 lbs
Before I put the Michelins on I had a st of the Hankook DH01's on but I was getting to much side wall flex so I went to a higher rated tire.

Everything fits with no modifications.

Thanks

It would be nice if a 17.5 would work.
3530 lbs @ 100 psi per tire.

You can't go wrong with Michelin in the 19.5 size. Be sitting down when you get the price... I did a lot of research and found (don't laugh) a Chinese brand called Sailun. Apparently they meet ISO requirements along with several other requirements that even well known brands don't meet. I have them on the front of our 2012 5500 and have been very satisfied with them. In 225 size, they cost me $190 each delivered to my door. My Michelins were $420 each. They are both wearing equally on similar trucks (GMC 5500). They are even regroovable. Oddly, the Michelins don't say they are regroovable, but they leave more rubber on the tire when down to the wear bars than most other regroovable tires do, so I regroove them anyway and extend their life another 40%
Stay far away from Continental HSR/HDR tires. Pure junk in my opinion. Much happier with Sailuns than Conti's.

Thought I'd update this thread with my experience with 19.5 wheels/tires. Several months ago, from a fellow TDR member who advertised them on the site, I bought a set of barely-used Rickson chrome steel wheels and Bridgestone M729 245 tires. I used them this past weekend for the first time to haul our new-to-us '12 Fuzion 302 toyhauler approx 250 miles round-trip at its max weight of approx 16.5K lbs (along with an aluminum ATV trailer hitched behind with one ATV on it). Aired to their max of 120 psi, and in conjunction with the airbags I already had installed, the difference these tires/wheels made in hauling the camper was AMAZING. There was no squirm or wander that I previously experienced with the stock tires while hauling our old toyhauler (which weighed significantly less than our new one). There was a little road noise from them, but not anything too bad, and I still need to re-calibrate my speedometer. Overall, it's probably the best mod I've made to my truck as relates to hauling ability and confidence.
