Curiosity
Posted by Debbie from Plano, TX, US on October 8, 2009
Why “the competition” does not offer 295/75R22.5 or 285/75R24.5? Why do they only do 275/80R 22.5 and 24.5? What are the advantages? HELP!!!
As a US based company, our tires meet the standards of the US based Tire and Rim Association (T&RA). Tire companies based in Europe make tires to meet the standards of the European Tyre and Rim Technical Organization (ETRTO). In some cases, they have come up with size designations that are different for tires of similar dimensions. This is the case here.
rotating drive tires on over the road trucks
Posted by bryan from carlisle, SC, US on October 6, 2009
Is there any proven advantage to rotating the drive axle tires on an over the road truck. I’m trying to implement a rotation program in my fleet and the techs are pushing back. I hate to see 4 new tires put on the rear axle and the front drives are at 1/2 tread. I would much rather rotate an x pattern when the tires reach a 3/32 to 4/32 difference to wear all drive tires out at the same time
The rearward drive axle tires on a tandem drive axle truck tend to wear faster than the foreward axle tires (as you mention). This is because, in a turn, the truck tends to pivot on the foreward axle and the rearward axle tires are dragged across the pavement. So, to get to your question, rotation of tires on the axles is a good thing to even out wear so that all the tires can be replaced at the same time. My suggested rotation policy is this: rotate from foreward to rearward axle (and visa versa) and reverse the direction of rotation (right rear tires go to left front, for example).
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
Posted by Walter from Dudley, MA, US on October 4, 2009
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.
