Choosing the proper tire?
Posted by Peter from Auburn, WA, US on July 31, 2009
I pull a 3 axle household goods trailer nationwide. We get into some tight places apartments, small streets ect. I can lift the rear axle to lessen the scrubbing and tearing. The axles are 14000 lb axles and we generally are 36000 to 40000 lbs on single tires. Tire size is 295/75R22.5. The ones on there are really not rated for the load and they are 14ply “G” rated tires. I have not had the trailer long nor have I had problems. When tires need to be replaced I wondered which would be best. Any information you could provide would be appriciated. Thank you….Peter
At 40,000 lbs on 6 tires, you need the carrying capasity of 6666 lbs per tire. The tire you are using is probably a load range G tire and has a capasity of 6,175 as a single tire. But, we make a 275/70R22.5 load range H tire (G104 RST) that is made for the type of service you describe. This tire can carry 6,940 lbs per tire as a single tire.
Is there a fleet inspection form i can download?
Posted by Rich from Muncie, IN, US on July 30, 2009
Is there a fleet inspection report vailable for download and printing?
With tread depths, air pressures and wear signs?
We do not have such a form for downloading from our website but, it a good idea. I will propose this to our sales/marketing people. In the mean time, you might consider some forms that are in TMC Recommended Practice RP 230A, "Tire Test Procedures for Tread Wear, Serviceablity and Fuel Economy".
regrooving tires
Posted by MERLE from ST CLOUD, FL, US on July 17, 2009
how do u know how deep to go when you regroove a tire
I think the only good way to know is to cut a section out of a scrap tire like the one you want to regroove. Cutting a section out of a steel ply tire with 4 steel belts is not an easy thing to do. Once you can see how much undertread there is below the bottom of each groove, you know how much rubber you can cut away. Regrooving in the US is usually only done on bus tires and the people who regroove are very familiar with the tires they are regrooving. For an inexperienced regroover, this is a very difficuldt job to do.
AIR PRESSURE 1
Posted by joel from St-Hyacinthe, QC, CA on July 17, 2009
Hi,
what should be the tire air pressure for the follow case?:
45 000 lbs
2 axles (8 tires)
And where could I find the table for this info?
This would depend on the tire size involved. You can find this information in our Engineering Data Book found here http://www.goodyear.com/truck/support/publications.html
Balancing retread/recapped tires
Posted by Mike from Bremerton, WA, US on July 14, 2009
Are recapped tires built to standards that permit balancing?
OR
Is it an accepted result that recaps cannot be reliably balanced?
A tire balancing expert would tell you that there is no such thing as a tire that can't be balance corrected. There is no reason that a retread should be any harder to balance than a new tire. Sometimes tires (new or retread) need more balance correction than what is acceptable. In this case, we recommend that the tire is rotated 180 degrees on the wheel and re-balanced.
