Load range F Carlisle tires

[NIsaacs]

It has a GTW around 10K, with 6K axles and 7K Dexter self-adjusting electric brakes. We don't try to pinch dimes when it comes to tires because we take it into some really nasty places in several states. We've used Michelin XPS rib E rated tires due to their steel sidewall and also our experience factor. They get replaced on a 9 to 10 year rotation, and it's time for the third set now. (It is stored indoors.) By comparison, the support box trailer that travels with it uses the same size tire but is maintained by a different office. They also use the same size E rated truck tires, but usually brands I have never heard of, or Dunlops when someone feels generous. Their experience isn't good.

I have no doubt the Michelin xps rib is a great tire, however they are only rated 3042 lbs. In your application of about 2500 lbs per tire of trailer weight you have a 500 lb extra capacity built in, so yes, I am sure you have very good luck with them. At 9 or 10 years of replacement rotation you don't tow it much.

It's hard for me to install 6,084 lbs of tire capacity on a 7k axle when I need all that and more. I also use up a set every 2-3 years depending on what trailer they are on. On a trailer with a set weight that don't change much, a tire can be matched to that weight. My loads vary every time. I also have a very generous loader operator at the cinder pit that always gives me more than I ask/pay for, since the extra is free I haul it

I put 45-50k miles on a set of XPS Ribs in 6.5 years, One was 8.5 years old and the other three 7.5. The one 8.5 years old started showing very small hair line cracks. They had 10 to 10.5K on the axles all the time with the 5th wheel trailer. They had 65% tread left. I ran them at 65 pounds inflation for the first couple years according to the placard, the trailer came OEM with LT235/85R16E. I noticed a slight bit more wear on the outter ribs after a couple years, so I upper them to 71 lbs of inflation. Only once did I find one low on pressure and tighten the valve core. Infrared heat gun always showed them running cooler than the TV tires, even in the SW heat. One in 90 degree SW weather going forward Phoenix to Palm Springs I found the shaded side tires running warmer than the sunny side. Then it hit me that I had 40 MPH wind straight on the sunny side for the whole 6 hour trip across the desert.

I replaced them with R250's which have a slightly better tread pattern for trailer use based on being about $50 per tire cheaper. I think the R250 is as good or maybe better than the Rib.

BTW I sold the used Ribs for 200 on CL to a guy with an old beater truck that he used to dump runs. He was tickled pink to get them. I threw out the unused spare 5 rib at 11 years old last year.

So I think most would be hard pressed to wear out a set of Ribs or R250s before they age out.

I would not hesitate to use either on a fully loaded 6K axle, as they are both really over built for a tire rated at only 3042 pounds.

Did you do the math right? That's a lot of miles possible for junky trailer axles. Tandem axle trailers are hard on tires by design. Mine melt off like butter.

You're right. We don't tow it much. But when we do, it gets towed long distances to ugly places.

Update: It has been about 14 months since I installed these tires. So far so good. They start with 13/32's, the front axle has 10/32's and the rear has 7/32's, typical tandem wear. Rather than rotating them I might leave them alone, that way I can buy 2 at a time, rather than 4. The local tire dealer has some 14 ply all steel he was telling me about, I need to go see what they are. I carry 85 psi in them and typically haul 5-6 ton loads.

My Sailuns are 14 ply, 110 psi Max. For the loads i run I generally don't run them over 100 psi. If I do need the full tire capacity (which puts me over the trailer GVW ) and I'm running any length of freeway empty and I have the means to air back up before I get loaded I'll air them down. Otherwise the trailer ride is so dang rough I feel it through the whole truck. Probably a combination of tire and trailer being leaf spring. My next trailer will definitely be torsion axles.

When I got my utility trailer (open box 5'x10' 3500 lb axle) they had carlisle tires on it some time with in the year getting off the exit to the market it seemed something was wrong ( hopping or vibration). When I got to the market the right tire on the trailer was missing aprox. 30% of the tread. I loaded up drove down the road where a tire store was to get new tires. They had carlisle tire. I asked if they any thing else they said they could a better brand from of one of their other stores. It took 30 minutes but it was worth the wait. I took many years to wear them out ( I put another set of those tires on. When I got the Liner the trailer was semi retired and last 10 years been used for storage for plastic crates.
