Dually tire question

[Pit Bull]

Which pair should be your best? The inside or the outside? Does it make any difference?

Pitbull, you should pair them up as close as you can to match the circumfrence, prime example is to take two tires with a big difference in circumfrence and mount them up, run em a wile and pull over to check the heat on the surface of the tire? Which one is hotter the tall one or the shorter one ? I think all would agree that the taller tire will be taking most of the load, right? so it should wear quicker right ? Guess what the shorter tire will wear much faster , infact about 2 times as fast, because on every revolution the shorter tire will have to slip so it can keep in rpm with the taller tire, this inturn creats heat and that is the worst killer on tires.

Match them as close as you can ... ... ... ... Kevin

I am curious, do you rotate your tires and are they still of stock size? I have rotated mine as per the owners manual, this is my first dually so I don't know any better, is anyone doing something different and for what reason?

I bought mine with around 30K miles on it and the tires were in need of rotating. I put 2 new tires on the front and took the best remaining 4 tires and put them on the back. I am now rotating the fronts side to side and they seem to be wearing evenly. The rears are wearing real evenly and square. I figure by winter and before the first snow I will be buying 2 new tires and moving the like new fronts to the rear and putting the new tires on the front. When I move the like new fronts to the rear I was wondering if I should put them on the inside or the outside. Tim I think you are doing it the right way, I did not have that opportunity because of the difference in wear on my tires. One thing I do like about my problem is that I figure I will only have to buy 2 new tires at a time. I think my wife would crap if I had to buy 6 new tires at a time.

Thanks for the reply. They are all Michelin LTX M/S 235/85/16. The newer one will just have a little more tread. I planned on putting the newer ones on the inside with a few pounds less air. Will that make enough difference in circumference to compensate for the tread difference?

 

[Whitmore]

Pitbull, I really dont know what the air psi will do for you, I years ago in my trucking days had a Michilin tire that would not wear out, I wour 3 other tires out when it was paired up to the Michilin, I finally had a tire technitian explain it to me , we measured the circumfrance and believe it or not the Michilin at 50 % wear was still like 3. 5 inches more in circumfrance, I started out cold and drove about 10 miles , pulled over and felt the two tires and sure enough the new tire was much hotter, this explained alot to me Kevin

Thanks for the input Kevin. I guess I'm screwed like the old saying "poor people have poor ways" I think the wife would kill me if I bought 4 new ones at a time so I will go with the 2 new in the winter.

As per the tire guy....

The best tire should be one the outside right rear (drive wheel). Obviously, the two best tires on the truck should be on the front! Now that's what he says... ...



Just another theory
