Rivering
Posted by Al from kernersville, NC, US on October 5, 2009
What causes rivering ? I have an RV running g670 275/70R 22.5 that has a rivering problem . Pressure is maintained at the reqiured amount for the axle weights. The unit is weighed about every 6 months.
How dangerous is this problem?
River wear is common on tires that have a very slow rate of wear. It looks funny but does not affect a tires performance or its overall mileage potential. If it is happening on your steer axle tires but not the drive tires, I suggest you rotate the tires from front to rear occasionally.
different size from original

I have ltx 225 75 16 will235 85 16 work without changing speedometer and fit on rim ok?
No and yes. The 225/75R16 and the 235/85R16 will have different diameters (and revolutions per mile) so a change from one to the other will affect your speedometer. But, every rim width approved for the 225/75R16 is also an approved rim width for the 235/85R16 so, you can't go wrong with the rim.
Tire Replacement - The Most Cost Effective Way
Posted by Tracy from San Francisco, CA, US on October 4, 2009
I purchased an old Crown School Bus with Firestone FS Plus 12R22.5 and Bridgestone R250. The bus needs new tires all around, total of 7 including spare. I want the most cost efficient method to replace the tires. Retreads and new mixture. Can I have the existing tires retreaded and then purchase new for the front axle? This bus is for personal use and not a school bus application.
Yes. Most commercial truck fleet do exactly as you have described. New steer tires are purchased and drive axle tires are retreads. Of course, your tire casing will have to be inspected to see that they are retreadable. The retreader will check the casings for damage or abuse and repair any nail holes that the casing may have. It is possible that some of your casing will be rejected for retreading due to damage that can't be repaired. If you do not have enough casings to fulfill all your drive axle needs (unlikely), you could purchase a "cap and casing" (someone else's casing with the retread of your choice). This should cost less than the price of a new tire.
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.
