2nd Gen Non-Engine/Transmission Dually Tires

[RClark]

I have been running Goodyear Wrangler HT on my truck for 30k. I never have inflated the dualies to more than 40 psi as the scales tell me that 36-37 psi is all that is needed-with the 5th wheel attached. When empty I ran at 35 psi. Recently I have started running at 36 loaded and 32 unloaded. Why- center wear. The tires are wearing out in the center, a sign of over-inflation. 1/16-3/32d difference.

If I had done this from the start I might not have had this problem.

Is this also caused by this particular tire? Goodyear is noncommittal and will not recommend an inflation less than 35 psi.

Has anyone else had this problem?

If not, what are you doing to prevent ti and what kind of tires are you running? Mine are probably due for replacement in 5-10k miles.

Are you talking about the tabs on your doors that say to keep the PSI low?? mine say the same thing, but my tires say max 65 psi... I run them at 55 in the summer and 60 in the winter... you will have less rolling resistance, thus making the life of the tires longer. . This may be a contributing factor, and I know that usually center wear means over inflation, however your tires were designed to run at a higher PSI... I would totally throw out the info on your doors, and try running those tires around 65-70 PSI... I am assuming you have 235-85R16 tires with a Load range E Rating?? If you are looking at new tires, I have seen the BFG Commercial T/A tires, and they seem to wear well. . you may want to check those out... Just keep in mind that those tires are designed to run at a higher pressure than what the door says... Keep me posted

I don't use the door tab. I am going by the inflation/weight chart that came with the truck, and the ones put out by Goodyear and Michelin. They give the inflation pressure for the load on the tire.

I saw some BFG's at Costco the other day and they were 2/3d the price of the Goodyears.

On my DRW I run 50 psi empty and 65 psi with the camper on. I did the same thing on my '95 DRW and the original Goodyear Wrangler went 55K when I replaced them. They wore evenly.

I'm running the BF Goodrich Commercial T/A all season version, 235/85 16 E on my dually and am having great success with these tires. I run 40lbs in the rears when empty and wear across the tread seems pretty uniform. They performed well last year on our round-trip to Alaska with the slide-in camper too. I usually inflate the rears to 65lbs or so with the Lance loaded up.

what's the load rating on those goodyears? they may not be heavy duty tires and not designed for the pressures that most run on these trucks with E rated tires

 

[RClark]

235-85-R16, load range E The sidewall says80 psi max . If I inflate to anything over 40 psi theere is hardly any of the tire on the ground.

My Goodyears were load range "E" and could take a maximum of 85 psi.

My 235x85s run at 80 loaded (Lance cab-over) and 50 empty. Wear is uniform across the tire. If you want to check your foot print try a puddle of water in/on your drive way then move the vehicle through and read the foot print after the tire makes it's mark on a dry section of the driveway/garage or whatever. Concrete works best.

In regards to the B. F. Goodrich Commercial TA, size 235/80/17 e rated M&S, had them put on my truck, 04. 5 DRW 4x4, this morning. Greate job, looks all prettyy, drove it down the street, the ride was smoother than the old Generals. That's when it all stopped. Got on the beltway about 65 mph, they started to sing, went to switch lanes, the back end got fishy-tailed and the front had it's own way about deciding how to get streight. Next came a launch from an intersection, I kinda powered down, the rear broke loose and was sliding around when I let off the pedal. I don't like these things and am taking them back. I called Tire Kingdom and they will have some new Michelin's Fri. Wasn't planning on that much muny, but sure didn't like the way those performed. The OEM Generals were better then that, they were gone at 40K. Any one had this problem. Just a note, I installed new shocks, the silver Monroe, and alignment is good, all other thing are good. And the BFG's got pretty good reviews. Hope the Michelins do better...

Due to money shortage, I took the wore-out (steel belts showing) 19. 5s and put the 16s back on with new Uniroyal Laredo HD/D 245. 75. 16 commercial tires, about $175 each out the door. They seem to ride OK and don't wallow like I expected them to. The glass guy who just replaced my windshield has them on the company van. He said they're the first tires they've put on that felt solid, considering the weight he hauls around. He said all the other tires let the van 'wallow'. At 20K miles, they seem to be holding up well, too.

Tire pressure will be problematic for a while. I've got them at 60 rear, 65 front. I may drop the rears to 50; they seem a little hard at 60. But wet/dry traction sure seems fine so far for my whimpering simp of a truck. I'll see how the 'all-season' tread works in whatever snow we get down here.

How much weight is on each rear tire of a dually when running empty? My figures come to less than 600 lbs.

I run 75's Goodyear silent armour on front @ 80 pis and a rare but very aggressive 10 ply Good-year G 9 0 on the rear. When not running interstate speeds I run the rear at 27 psi. The tread is wearing perfect. The front tend to wear the outside of the tread fast because I cannot rotate them.

Those who have tried driving a dually on soft ground know how fast the front tires will sink. The wider fronts help keep it afloat.

 

[Bovee]

i have cooper discover stt's. there a more aggressive tire but do very well with little road noise. i run them at 60psi with my fifth wheel and 45 without. and the wear is consistent throughout. i love these tires. gives the truck a tough rugged look with out the annoying roadnoise.

 

[Texis]

I have a long bed 2500 4x4 and 285s Mich, if I run them above 32 psi only the center section is on the ground. I will boost them up to 55 psi if I'm hauling heavy stuff, but day to day they stay at 26-28 psi and the wear pattern is very even, ride is nice as well.

 

[georgej]

Of four sets of tires (Goodyear,Michelin,Toyo,Uniroyal)I've run,only Toyos have worn in the middle. The strength of the belt must determine that to a certain degree as I've always run 40psi empty and 55 with the 5er.

 

[drag racer]

Just curious - for you guys running load range E tires (80 psig) at less than half of max. inflation, what is your honest mileage???

I run nothing but Michelin, always at 80 psig, loaded or not, for maximium mileage and minimum heat, and have not seen uneven wear issues. Plus, the AZ summer heat and low tire pressures are a recipe for disaster. I guess the cooler climates can get away with it more.

I run General AmeriTrac, they came from the factory and am now on my 2nd set. Like the door says, unloaded I run 65 front, 40 in rears. Loaded I run all 6 tires at 80psi. Always have great tread wear and don't rotate although I should!

 

[Skydiver]

I can buy the G - 9 0's for $60ea. I have 36k on them and they are about ready to replace with another new set in my basement. They do not have much tread, but the traction is unbeatable.

I could not post a picture, but here is a link.

The shop did a lousey job of balancing the tires. I have had that problem many times on my work vans. all 1 tons, heavly loaded, the back wants to change lanes faster then the front. re-balance the tires allways fixed it. If the wheel shutters back and forth on the highway, it's usually a front wheel baklance problem.



All load e tires, very heavy van, run around max tire pressure, rotate frequently, I can get 50,000 out of a set, Michlens, goodyears, or firestones.

 

[Extreme1]

When empty I ran at 35 psi. Recently I have started running at 36 loaded and 32 unloaded. Why- center wear?

ROTATE!!!



Rotate the tires and you may be surprised how many more miles you get out of them...



I always run low pressure in the rear tires (don't haul much) and had the same situation. Since I put the forged Alcoas on it makes a lot more work to rotate the tires (you wnat to keep the wheels on the original end) so I quit doing it. Until I wore out a front pair.
