tire mileage...

[spongebob]

my original bf goodrich tires got 60k with some tread left on them when i changed them out to toyo's,(285/70/17) i got 32k on them and there toast..

man..whats up with that?? and the toyos wernt cheap !!

[DarylB]

never ran Toyo's. I've got a set of Michelin LTX A/S that are at the 64k mark now with good tread left (hoping for around 80k miles). 265/70/17's.

How much air did you run in them?

I've always gotten about 50K to 60K out of BFGs. No experience with the Toyos.

I run Michelin LTX M/S and X-Radials that always get me 60k - 65k miles. The X-Radials are a super nice ride too.

70psi..there even on the wear. i may go back down a size..im running 285's

Have you compensated for the tire size increase? The 285's (~33") will have about a 7-8% increase in rollout (depending on mfg/model), compared to stock size tires. This will increase your actual miles traveled, compared to the odo reading.

Tire size and compounds have everything to do with longevity. The larger, higher performance range tires tend to have a softer compound, translating to less miles. Mud tread tires are almost always the worst. I get 50K+ out of Bridgestone Dueler A/T tires, and just over half that with M/T's. My experience with other brands is about the same ratio. This is with 285's.

Road surface temps and construction makes a huge difference. Notice accelerated thread wear when we run heavy loads across chip sealed (a thousand billion tiny knives) or asphault (holds heat) surfaces rather than white concrete slab interstate, for example. I am certain we get more miles out of our tires in Minnesota than we would if we were based in Texas. (However any savings are certainly given back 10x in fuel consumption during the winter...)

Chip seal is the worst - it makes these micro-scuffs and thread face cuts that connect and cause the tire to 'chunk' away, rather than wear smoothly and evenly. The chunks are tiny, but you can see them on your hand if you sweep it over a hot tire on a hot day. Little tiny balls of rubber, and your hand comes back blackened. Sometimes you can even smell the tires when stopping to fuel. The outside (ditch side) trailer tires always wear quicker due to the crown of the road and the weight shift of the load. They probably carry 300-500# more per tire as a result.

Trailer tires on the back (third) axle that swings while the front trailer axle pivots are very prone to this, as well. I am constantly rotating the back axle tires to the front axles on my boat transporter to keep them in sync.

The best all-around wearing tires I have found are are Michelins, mileage-wise. Cost wise not so sure. Not unusual to get 50K loaded towing miles with them. I rotate 2500s and 3500 SRWs, but make no attempt to rotate on duallys. Usually when backs are done, the fronts are scrubbed off on the outsides, and are ready to be replaced as well. In our world, rotating fronts to rear outsides actually acclerates the demise of the entire set of six...you can extend the life of steers slightly by swapping left and right fronts.

Factory set lasted ~ 35K, then went to 265 x 75-16 sized (all this size since) Toyo AT's that lasted about ~30K, since I was not happy, they sold me a discounted set of another series of Toyo's that last ~30K.. went with new set from Walmart after that.. so I did not get good wear from the Toyo's.. I don't run them down to the cords but they where pretty low when replaced.

Liek stated above compound plays a huge role in the tiure life vs traction balance. I've had excellent results from Michelin rubber, but the aggressive bite is not there. I currently have Michelin LTX-AT2 on my 2005 and these have excelent bite so we'll have to see how long they last...

i ordered 4 bf goodrich 285/70/17's for my truck (10 ply)
its moderatly loaded (i do commercial refrigeration)..
what kind of psi should i stuff in them?

My experience is that the Bridgstone Revo's and Michelins last the best with the Bridgestones winning out by a good margin because of better traction and handling.

There will be a recommended maximum pressure but a general PSI is around 50 - 65 psi (for my prefernce on a 10-ply).

...what kind of psi should i stuff in them?

If you know how much weight the axle is carrying you can get a close estimate by dividing the weight by 2 (two tires on the axle) then multiply that by the max psi divided by the max weight for the tire.

Example: if you have a tire that carries 3042 lbs at 80 psi and your axle load is 4000 lbs,

4000/2 = 2000

2000 x (80/3042) = 52.6 psi

thanks guys...

beers are on me..
