11R22.5 Tire Weight
Posted by Brian on November 29, 2006
I have a bus and it shows the vehicle weight based on 12R22.5 tires at 110 psi. I assume the weight rating includes the weight of the tires. What would the tire weight of the 12R22.5 at 110 psi be? (so I can figure out the weight of the bus itself) Whoever had this bus before me was skimpy on weight considerations and slapped 11R22.5 tires on it so I am trying to figure out how much weight I can add to the bus without worrying about reaching the max load. The 11R22.5’s also read 105 psi single and 95 psi dual with certain weight ratings, yet the bus displays that the 12R22.5’s should all be at 110 psi (single and dual) I assume I should go by the tire specifications.
If you want specific tire weights, you will need to find the info for the specific tires on your bus. In our case, we publish all the weights, load carrying capacity, etc. in our Engineering Data book that can be found here http://www.goodyear.com/truck/tireinfo/publications.html
In your case, it might be best just to have the bus weighed. Try a grain elevator or a gravel pit. They can weigh the whole bus or at least the front and rear axle weights separately.
Goodyear tire manufacturing date
Posted by Greg on November 29, 2006
I purchased a 1970 Corvette with Goodyear Wingfoot 255 r60 15 tires on it. I can not find a date code on them and I am trying to determin how old the tires are. They are in great shape but I am concerned that they are too old it be trusted.
When did they stop making Wingfoot tires?
The following quote is from the National Highway Transportation Safety Association and it details the U.S. DOT Tire Identification Number and what the letters and numbers mean.
"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."
