Heavy duty lifting equipment and tire rating
Posted by Michael from Midland, MI, US on June 3, 2009
It the capacity rating on a tire meaningful when lifting vehicles with mobile column lifts. My concern is lifting a truck with twin alxles in the rear (four tires per axle) but the lifting equipment is placed under one tire on each side, so one tire is taking the load of 4 tires when lifting the vehicle for maintenance. The lifting mechanism has two angled supports that slide into the tire while on the ground, therefore there are two pressure points when lifted.
The typical load capacity that is published for tires is at highway speeds. When the vehicle is not moving, the load that can be carryed by a tires increases. So, although you should be OK, it would be a good idea to become familiar with the static load capacity of the tires on the vehicles you are lifting. You could get in touch with the Tire and Rim Association and purchase their annual yearbook that has this info. www.us-tra.org
Minimum Tire Pressure on motorhome
Posted by Joel from Barberton, OH, US on June 3, 2009
On 36 ft. Holiday Rambler class A motorhome, the Sumitomo tires show maximum cold air pressure of 110 PSI. ( 245/75R 22.5) on the sidewalls. Checked air pressure. It’s 91.5 on fronts and 86 0n rear (duals, not tag axels). What is the correct or best pressure I should set them at?
The correct pressure depends on the load you are carrying. You need to have the motorhome weighed by axle to make this determination. Weigh the motorhome when it is loaded as it would normally be when you are traveling. Divide the axle weights by the number of tires on the respective axle. In your case, divide by 2 for the steer axle and 4 for the drive axle. Then use the published load/inflation charts for the 245/75R22.5. In your case, you should find these on the Sumitomo website or by contacting a Sumitomo dealer.
G670 RV vs. G169 RSA
Posted by Dve from Mason, OH, US on May 26, 2009
My 2008 Damon motorhome has G67 RV 255/70R22.5 and I need to replace the steer tires. The local dealer does not sell the G670, but has suggested the G169. What would be the pros or cons of the switch?
I suggest the G670 RV tires for your motorhome. If it is a Goodyear dealer, he should have no problem getting the tires even if he currently has none in stock.
recommended tire inflation pressure
Posted by bill from nashville, TN, US on May 12, 2009
I need a source for labels(stickers) that can be placed above the fender well of our trucks that show techs and others the recommended tire inflation pressure.
Tire inflation pressure stickers are available at the American Trucking Association at the following web address http://www.atabusinesssolutions.com/p-46-ata-tire-inflation-update-decals.aspx
rivering tires
Posted by Roger from Cheyenne, WY, US on May 9, 2009
I have a class A rv with Goodyear G670’s and I am experiencing rivering on some of the tires. I have heard their is nothing that can be done. Is that correct?
Most people call this river wear. It is common on tires that have a very slow rate of wear and very little scrubbing from lots of turning. You may not like the way it looks but, in a sense, it is sort of a good thing. "They" are right, not much you can do about it. The long term result will not affect the overall tread life of your tires.
