Does goodyear recomend filling their commercial truck tires with nitrogen and does it affect their warranty?
We neither recommend or discourage anyone from using nitrogen but, using it does not effect the warranty.

i have a dodge dually on 24.5 and i am moving to new hampsire where it snows alot. what would be the best tire for the snowy conditions.
If 11R24.5 will work, we have several tires that may fit your needs. A G622 RSD is a very new tire in our line. There is also a G164 RTD and a G182 RSD in the same size. You can take a look at these tires on our website www.goodyear.com/truck
tire wear on outside edge
Posted by Bruce from Arroyo Grande, CA, US on August 12, 2009
I am having wear on the outside edge of my right front steering tire but only outside rib , 180 degree of tire’s edge outside rib only 1/4″ has gone away at 12 o’clock & 1/8″ at 3 & 9 o’clock, the 6 o’clock looks normal with 40K miles on it the left tire look’s fine. 12R22.5 on 8.25 rim 14K lb. on front axle & 120 psi in tire Max.It’s on a MCI 102A3 buss conversion, tires were balance, & check for proper beating set on rim Too. Local tire shop had no help with it.
From what you describe, it sounds like what we often refer to as chamfer wear. This is usually found on tires that are wearing very slowly. Not much scrubbing from frequent turns. The design rim width for your 12R22.5 tires is 9.00 inches. The fact that you have the tires on an 8.25 inch rim might be contributing to the wear condition. There will be no loss in overall mileage from the tire so, I suggest that you continue running the tire and do nothing.
Fuel Economy 102
Posted by Veral from Springdale, AR, US on August 3, 2009
California has passed a law that will go into affect in the future that will make it illegal to operate equipment in a tradition over the road capasity that has retreads capped on other than Smartway approved (fuel efficient) casings. They are not regulating the retread, only the casing. My question is since 60% of the fuel economy comes from the tread, do I gain anything by putting a non-fuel efficient retread on a fuel efficient casing?
Well, 40% of the rolling resistance does come from the casing. I can't speak for all tire manufacturers but, I can tell you that the casings for some fuel efficent tires are different (than standard casings). So, there could be some fuel efficiency advantage to the SmartWay approved tire casings. There is work being done by the SmartWay people to approve certain retreads but, this is a work in progress.

What’s the difference between 11R 22.5 and 275 80 22.5 tires?
The 11R22.5 is consider a "standard aspect ratio" tire. To the average person this means nothing but to a tire designer, it means that the section height and the section width are nearly the same (now you are really confused). The 275/80R22.5 is a low profile tire. This means that the section height is smaller than section width (in this case 80% as tall as it is wide). The diameter of the two sizes you mention are about the same but the 275/80R22.5 is probably more than an inch wider. The load range H version of the 275/80R22.5 carries a greater load than the load range H version of the 11R22.5.
