Goodyear G159 tires

Hi!

I've got Goodyear G159 245 70R 19.5 tires on my 1998 Bounder. They were on when i purchased the coach about a year ago. They look pretty good, but I can't seem to find the build date on them to see if they need replacing. Someone please help!!

Thanks in advance!
Matt

A good explanation with photos is found at: Tire Tech Information - Determining the Age of a Tire

Thanks for the link! What if I don't have a DOT number on the tire?

You do have DOT dates on the tires, it is required by the Federal Gov, they may be on the backside of the tires. Keep looking.

Ok. I've attached a pic showing one of my front tires. If I'm reading the code correctly it was manufactured in 1998?? The code says MJ93 PMAW 098

The other tires do not seem to have the DOT codes on them. As you will see in the other pic. The only set of numbers I see are 300460 GRW 43EP. And that number varies on the first set of six digits for the other tires.

Thanks again for all the help!!
Matt

I would say that the 098 codes reads the 9th week in 1998. That type of code indicates the tire was made befor the year 2000. That is BAD. What does everybody else think? Time for new tires now. If it was a post 2000 tire the code would be 0908 for the 9th week in 2008. I would say that they are the original tires that came on the mh.

Matt,

Please replace your tires. If you can't afford to replace all six at once then at least replace the fronts before you do any interstate driving. A blowout on a motorcoach is something to be concerned about. The least that will happen is lots of damage to the coach. In most cases, motorhome tires always age out before they wear out. There are many cases of serious accidents as a result of tire failure on a motorcoach. The tire and tread usually look good but the tire fails. The general consensus is to replace the tires when the age is 5 to 7 years.

Bob

Every car & truck tire sold in the USA will have a DOT code stamped somewhere on the sidewall - federal law.

Yeah, that is a 1998 tire. Over 14 years old now. No matter how good it looks, it's long past time to replace it. Even Goodyear won't suggest running it beyond 10 years.

SEE:

Tire Tech Information - Determining the Age of a Tire

Pre 2000 tires use 3 digit date codes.

Post 2000 and later use 4 digit date codes.

I believe that makes the OP's tires a TAD old.
