Sidewall Markings

........ DOT stands for Department of Transportation. The 10, 11 or 12 digit code appearing after the DOT designation gives information such as the week and year the tire was produced, as well as the manufacturer, plant, tire line, and size. The first 2 characters designate the tire's manufacturer and plant code. The third, fourth and fifth characters, are the tire size code. The last three or four numbers (4 numbers for years after 2000) are when the tire was manufactured. The first two digits of the date code represent the week and the last 1 or 2 digits represent the year.
Maximum Inflation Pressure is the highest inflation pressure that the tire can withstand. This is not, however, the recommended inflation pressure. Inflation pressures should never be below the recommended pressure or above the maximum pressure branded on the sidewall. Also see Air Pressure.


Hope this helps

 

Thanks, Mr. Ed - - just what I needed. Mine must have been mfg in the 12 week of 99, making them about 5 1/2 years old - - just right to blow. Drat it. Well, we will drop by Goodyear and see what they have to say. No harm in trying.

Thanks for the website, too. Good one.

Just got back from Goodyear. They could find no physical damage to the tire such as running flat, puncture, hitting something. So, we are putting in a claim for damage to the RV and settlement on the blown tire and replacing the other three also. They have a new tire just out that is replacing the old G159. Supposed to be stronger sidewalls - - the belts are wrapped up into the bead differently helping to prevent breakdown.

Hopefully Goodyear will come thru with some help on the damage to the fiver. That will be nice.

 

The G rated tire should be a 14 ply rating not a 12. I differ with what was said about pressure, the more the pressure the cooler they run. run max pressure.

 

Thank you Mr. Shovelhead !!

Sorry I didn't answer sooner.

Haulin,
The weight rating is based on 110# pressure - - that is what I keep them. Since we round them off anyway in scuffing, this helps keep the wear more level. This was the first question I was asked - - what pressure I run. He looked inside and could see some marks from running low - - well, duhhhhh, try coming across three lanes of interstate slowing down from 65 with a blown tire and not have a really gross looking mess when you are done.

The Goodyear guy said 12 ply - - I will re-question that on Monday when they put on the new ones.

Bob I ran them for quite some time on the truck with loads, much of it with single wheels. The only problem I had was the rubber stems can blow out. Use brass bolt in stems. I ran the 110 pressure. Unless they have change them they were 14 pr. They took them off the market for some time so they may have made changes. Goodyear also makes another number for the same purpose, 269 or something like that, not sure on the number. They were also G rated and were available while the G159 was not. The G159 was designed for use with FedEx and UPS.

They are ideal for RV use where the mileage is not too high. They have less rubber on them than other brands. Michelin XPS rib gives me over 100,000 miles wear while the Goodyear G159 is much stronger but yields about 60,000 miles.

 

Can i get a link to any of these? I cant find a 16" tire > 3042# in a 235/245 or 3415# in a 265... I've beeen checking out http://www.goodyear.com/truck/

According to their load inflation table looks like I'm looking for a 235/85/16 that'll go up to 3750# @ 110 PSI ? Doesn't need to be a goodyear, just any high load 16" tire.

 

The new Goodyear G614RST is a tire built for trailers and seems to have replaced the G159LT. I have four going on Monday. 235/85/16 - - it is a radial but rated for trailers, not for trucks. Carries the 3750 rating. Very different tread design supposed to reduce wear from scuffing. Glad to get this settled. Hopefully Goodyear will come thru on the damage claim and help me out.

You guys got me all paranoid - I just bought new rubber for the truck and I had to go outside and check the dates. I can only see the dates on two of the six tires(it's dark and the other 4 codes are on the inside) but the two I can see are 2104. Good to know!! Hopefully all of them are the same.

I always seem to learn something on this site even when I'm not trying. Thanks everyone!

 

I bought a set of 225-75-15 Carlisle Trailer tires this week for my new 19' 10K car Hauler Trailer I have ordered. This was on their web-site and is good information it seems. jim

Do you need to replace your Trailer Tires?
Did you know that your Trailer Tires may be worn out even though they still have plenty of tread left? This is because trailer tires have to carry a lot of weight all the time, even when not in use. It is actually better for the tire to be rolling down the road than to sit still. During use the tire releases lubricants that are beneficial to tire life. Using the Trailer Tires often also helps prevent flat spots from developing on the tire.

If one tire fails, the remaining tires will have to suddenly compensate by supporting the increased load the failed tire was carrying. This sudden increase of weight may overload the other tires causing a chain reaction blowout or other internal damage. If you have experienced a blowout, make sure you check the other tires for damage and/or take your tires to a local tire shop for evaluation by the experts.

The main cause of tire failure is under inflation. Check your tires at least once a month for proper inflation levels. Carlisle Tire and Wheel recommends adjusting the air pressure to the Maximum pounds per square inch (PSI) listed on the sidewall of the tire. If you inflate the tires to less than the maximum inflation level, you dramatically reduce the load carrying capacity of thetire.

Tires are not completely impervious to air loss; in fact tires can lose 1 to 3 PSI per month. This is because molecules of air under pressure weave their way from the inside of the tire through the rubber to the outside. A drop in air pressure could cause the tire to become overloaded, leading to excessive heat build up. If a Trailer Tire is under-inflated even for a short period of time, the tire could suffer internal damage. The Rubber Manufacturing Association (RMA) states that a tire run at less than 80% of the maximum inflation could cause damage to the tire. Again, if you feel that your tires have been run underinflated
have them checked professionally at a local tire service center.

High speed towing in hot conditions degrades Trailer Tires significantly. As heat builds up during driving, the tire’s internal structure starts to breakdown compromising the strength of the tire. It is recommended to not exceed 60 Miles per hour (MPH) while towing a trailer.

3 to 5 years is the average life expectancy of a Trailer Tire. After three years you should consider replacing your Trailer tires with new ones even if the tires have adequate tread depth left. After five years Trailer Tires are considered worn out and should be replaced.
Imagine staying in the sunlight all day everyday with no sunscreen! This is what your tires have to endure daily. If you are storing your Trailer for an extended period, make sure that you store the tires in a cool dry place such as a garage or under a shade tree with tire covers to protect your Trailer Tires from the harsh effects of the sun. A thin piece of wood under the tires during storage will extend your Trailer Tires life.

- Summary Maintenance Tips -
•Keep your tires air pressure at the Maximum PSI recommended on the sidewall of the tire
•Keep a cap on your valve stem to prevent contamination of the internal rubber valve
•Always travel with a spare and check your spare tires air pressure along with the other tires
•If you experience a blowout, slowly move over to the right off the road to change your tire and check the other tires for possible damage
•Don’t overload your Tires. The maximum load is listed on the sidewall of your Trailer Tires
•Give your Trailer Tires a visual check before each trip
•Keep your Trailer Tires in a cool dry place and out of direct sunlight during storage
•Replace your Trailer Tires every 3 to 5 years

 

New RST tires went on today. Sure a tough tire and heavy. Look good. Hope they hold up good and hope Goodyear comes thru with some help on the repairs to the fiver.

Blowout Bob,

Repeat after me; "Tire Sentry, BrakeSmart". Durn, I promised not to do that.

 

I had one that let loose2 days afther xmas we where at Beaver Bend for xmas and on the way home running 70 and looked in the rearview and smoke ,I said oh no and about that time the tread let go, rubber flying every where ,the big promblem was we had to drive 10 miles before we where able to pull over. I guess it was my lucky day the metal plate above the tires was bent a little, easly fixed and no damage to the trailer.Made the tire shop the next day new tires all around ,don't want to go though that again.

 

You are one of the nastiest, meanest biggest bullies I have ever NOT met. I just can't stand your constant pressure on me to spend my money. I think this is entirely un-American. Oh yeh, come to think about it, you are one of those crazee Canucks.

Yes, you promised you would stop this harrasment. I am going to have to have a cease and desist order from the courts of public opinion. All who think Casey is harrasing me, say "HEY".

You are a mess, boy.

HarrassedBob

ps: the tire blew, exploded. Tire Sentry probably would not have caught it until the actual explosion. I had just checked the tires and few miles previously.
