Trailer tire -

[docirv]

I read that tire life is about 6 years before dry rot will set in or breakdown of the rubber occurs. They say that a lot of tires are several years old when purchased and that the date of manufacture is located on the inside face of the tire (if it is a whitewall the date will be on the opposite side) and the date is in the format of 0910 as in 8th month of 2010. When buying new tires you should always check the date of manufacture to be sure you are not getting a tire with limited life left.

and the date is in the format of 0910 as in 8th month of 2010.

Really? Again your mind is detached from your typing fingers......... Sorry, but it IS MY JOB, & I got it before Bryce did.

If you still haven't figured it out: 0910 is September, 2010
8th month of 2010 would surely be AUGUST.

I'm good at my job and believe I should get a raise.............

maybe some of you dont have enough ply tires that can handle enough load and air pressure. mine are 50 psi tires,which should be a minimum on a bass boat. my skid loader trailer tires are 100 psi 12 ply..lol

Embrey, the psi of your tire varies with the weight of your trailer. For instance, I inflate mine to 35 psi because that is what it should be inflated to at a weight of 3,000 lbs.

Over-inflating your tires doesn't accomplish anything but uneven tread wear.

I will direct you to this chart.

none of my tires are overinflated...not all tires have the same psi capabilities...and yes it wouldnt make sense to inflate my tires that will handle 100 psi all the way to haul around a lawnmower. but i haul around 10,000 lbs on it.

After looking at the OPs failed tire pictures it would be very difficult to determine the cause without having the tire in hand for closer investigation.

The H188ST is a common trailer tire found at such places as Sam's Club. The OPs are bias tires rated at 1760# at 50 psi. The life expectancy for such tires is 5,000 - 12,000 miles or 3 - 5 years. Almost all manufacturers of those tires require them to be aired to full sidewall pressures at all times. Some manufacturers such as Carlisle will not honor warranty claims if they suspect the tires have not been kept at full sidewall pressures. While I'm on the Carlisle ST line of tires I'm compelled to warn all owners of them that their warranty period is among the shortest in the ST industry - two years from date of purchase.

ST tires cannot be manipulated to extend their recommended speed limitation of 65 MPH. That procedure is only authorized for truck tires.



p.s. If a closer inspection of the failed tire reveals melted cords it's an indication that the tire overheated, lost its air and failed. Speeding above 65 mph with less than the recommended tire pressures will cause such a condition. Bottom line - keep your trailer tires aired to the trailer manufacturers recommended pressures - found on a tire placard - or full sidewall pressures.
