year of manufacture
Posted by Vincent from Boca Raton, FL, US on October 4, 2009
We have tires on our trucks and are trying to determine the year of manufacture
The following is from the National Highway Transportation Safety Administration website:
U.S. DOT Tire Identification Number
This begins with the letters "DOT" and indicates that the tire meets all federal standards. The next two numbers or letters are the plant code where it was manufactured, and the last four numbers represent the week and year the tire was built. For example, the numbers 3197 means the 31st week of 1997. The other numbers are marketing codes used at the manufacturer's discretion. This information is used to contact consumers if a tire defect requires a recall.
RV Replacement Tires
Posted by Roy from Franklin, TN, US on October 1, 2009
I am about to replace all six of the Goodyear 391E Size 295X80RX22.5 tires on my 2002 motorhome due to age rather than mileage or any visible dry cracking. Of course, Goodyear has the new 670 series but I don’t like the price or the captive marketing done through Camping World outlets only. I am not sure why I need the new 670 as I was quite happy with the 391’s. I am aware of the new 395LHS but I am not sure that it comes in the size I have on my 40′ Monaco Windsor with 8.25″ wheels. I am also aware of the controversy about the use of these 8.25″ wheels as apposed to the 9.00′ wheels and I need to know if the tires will work and have full warranty on the 8.25″ wheels. Will you please provide me the details of all options for my application and also your suggestion and why. I need detailed info as opposed to tire names (i.e. it’s an RV Tire) to help me with my decision. I understand tires and truck steering designs so I can use the detailed discussion to my advantage. If I get lost in the details, I will ask another question to clear it up..
First of all, Camping World does not have exclusiver rights to our G670 RV. You would be able to get them from any commercial tire dealer. Second, although the 9.00" rim is the preferred rim for your 295/80R22.5 sized tires, the 8.25" rim is approved for this size. The G395 LHS does not come in this size, the G670 RV does. So, I suggest the G670 RV in the 295/80R22.5 LR-H size and load range that you can purchace at any Goodyear commercial tire outlet.
Used all position tires as steers
Posted by James from Royersford, PA, US on September 27, 2009
Just curious as to your opinion of putting a used, all position tire, removed from a trailer, into a steer tire position?
A tire marketed as an all position tire is, just that, capable of being a steer, drive or trailer tire. It should be fine as a steer tire.
Side wall cuts
Posted by Ricc from Altaloma, CA, US on September 18, 2009
I would like to know how big can a side wall cut be befor it is unsafe to run on a fire truck and if there is no steel showing does it make it safe to keep in service. Thank you.
If the steel casing ply is not exposed, the tire can continue to run. It would be a good idea to inspect the tire often since the cut may deepen over time when the tire flexes.
Tire rotation on a Twin Steer / 3 Drive Axle Truck
Posted by David from Brownsville, WI, US on September 10, 2009
The company I work for rotates tires on all trucks on a regular basis. We bought a new truck with twin steer axles with 425/65R22.5 and 3 drive axles with 12R22.5. What would be the proper rotation for this truck?
Twin steer axles and three drive axles. Wow, an unusual truck to say the least. I think the important thing with tire rotation is to move tires around the vehicle on to different axles and to reverse the direction of rotations. So, in the case of the steer axle tires, I would rotate the left side tires to the right and right side tires to the left side and put them flip flop them between axles. Example, left front steer axle tire to the right side of the rear steer axle. For the drive tires it becomes a little more complicated. Again, use the idea of moving right side tires to the left side and visa versa. As for the axle placement, move the forward axle tires to the center axle, center axle tires to the rearward axle and rearward axle tires to the forward drive axle.
