2nd Gen Non-Engine/Transmission Dually tires

[RClark]

I have 2 different mileage tires on one side of my truck(due to gross stupidity on my part). Ther is about 2/32d" difference in tread depth.

Would running one tire at a lower air pressure help to equalize tread wear or would it make any difference?

If you don't have a match for one tire or the other I suggest you keep them inflated equally. Eventually they will be the same tread depth. Running one low could cause premature failure on that tire.

Think about this for a minute. I used to think the taller tire would wear out faster and match the shorter less tread tire. NOW my buddy owns a tire store and had a dually he told me when he ran lower tread tires next to a taller tire the shorter tire would scuff the ground because it is touching the ground but it actually has less revolutions per mile. See I wold you it would take a minute to think about.



Let us know how yours end up wearing

... ... ... ... . because it is touching the ground but it actually has less revolutions per mile.

That is the dumbest thing I have heard in a long time.

Smaller rolling diameter less revolutions. . actually pretty simple. I know hard to get your mind around.

take a yellow or white marker and mark across both dually wheels, drive a few blocks, turn corners, back up, do whatever you want. If the revolutions are different the lines still won't be line up, if they aren't I sure want to see that dually, I needed something to smile about today and this has given it to me!!!!!!!!! thanks

A smaller diameter tire would be more revs per mile, not less. However since it is bolted to the larger tire/wheel it is the same. Or does your hubcap revolve at a different RPM than the wheel?

The fact that they are bolted together is the reason behind this theroy. Of course they arent going to turn at different revolutions BUT the larger tire covers more ground in a revolution and the smaller tire has to follow even though it would be taking up less ground therefore it scrubbs the ground a little. Come one think about it, its not that hard to understand.

I have 2 new inner dual tires and 2 half tread outside tires. They have the same air pressure in them, they make the same rpm's, what will happen in this case is the minimallyh taller tires will wear slightly quicker as they bear more weight! right? if I spin my tires more rubber will come off of the taller tire as more of the taller tire is on the road surface

Correct less revs on the shorter tire.

The Shorter tire is actually getting dragged across the ground ever so slightly because the taller tire IS bolted to it and covering more ground than the shorter tire. That's kinda simple? Ok keep the funny stuff up I like it :-laf



BTW my hubcaps never turn as many rotations as my wheels because they usually jump off and take a nap on the side of the road.

I really thought that was the case too but I still stand behind my dragging the shorter tire theroy because they are both touching the ground and I don't think bearing more weight would make that much of a difference because after it squats that half of the tread depth the shorter tire is already bearing some of the weight. As far as spinning your tires..... hold on... looking thorugh my nuclear engineering books... . Ok Good question.



Are you guys gonna make me go mount different tires on the back of my truck lol.

 

[LBARTLETT]

I haven't thought this hard since before the last election on who to vote for!

 

[champspa]

Ok , you've got me laughing , so put it on the inside where the crown of the road is taller. now what do you say about turns per rev. :-laf:-laf:-laf:-laf:-laf:-laf

 

[HCannon]

Put you a short tire with tall tire and see what happens. I thank you will find that the short one will wear faster, or I will say that what happen for me. The tall one will be carring more weight but the small one will have to scuff to stay with the tall one.

#@$%!by the way, who did win the election????????#@$%!



let's all hope we still have a chance to change things in 2010:-{}



ran over a dog today by the way, thank God I just hit him with one dual, it was the shorter one and just "scuffed" him up a bit:-laf

OMG now that's some funny shtuff! lucky for the dog you had that shorter tire. He ran back home and his family renamed him "Scuffy"

I'm just a smart *** but I did think that was funny, I love the TDR

It's ok to be a smart *** I have to hold back alot cuz I see humor in stuff that might not be so funny... . BTW do you agree with my scuff theroy yet?



I have to agree the way I proposed it at first did sound like I was saying the shorter tire turned less revolutions when I meant it just wanted to really bad but it couldn't cuz it's bolted to the bigger bully tire dragging it allover town.

 

[LBARTLETT]

I understand the scruffing theory however I would think there was enough weight it wouldn't happen, that the tire sidewalls would equalize the needed height, with the scruffing theory would the shorter tire wear funny? if so I'll watch for it, I've been trying to get by until I can get a new set of 6, I have 4 (don't match in 4's only pairs) that probablyh have 1/2 tread and I can't bring myself to take a beating on them so I've been trying to piece along until they're worn out, I figured wout I should never do this on a dually, I guess I could put them on my wife's F-350, they'd last along time as the piece of **** never runs, comnfortable but always broke down with 97K on it, the white whale's going strong at 180k, let me know if I can see the wear and I'll watch for it
