Carlisle Tire Report

A couple of weeks ago I decided to go with the new design Carlisle tires instead of Maxxis. I caught a lot of flak from my the owner (70+ years old) of my day job for telling him everyone on the internet is raving about Maxxis tires and he should put some on the one 14x7 enclosed (7k gvw) trailer for his business. He did, and one blew out within two weeks. I don't know the speed or conditions, as I wasn't driving but know the trailer was empty. The driver said he wasn't speeding. As the max speed on the highway this happened on is 65mph, that puts it within it's rating. I got called a bunch of names and the maxxis cheerleaders on the internet got called a bunch worse.

I have a Keystone Springdale 253 FWRL. Equipped with 205/75/15 LRC Tires. That is what exactly I put on it as I found stamped on the one wheel, "Do not exceed 55 psi." I bought 6 brand new Carlisle Tires in that size and an extra wheel so I would be prepared as we were heading to Florida. I loaded the 5er up with approximately 500lbs of items so that should have put the 5er in the 7600-7800lb range.

I left Gettysburg on a 15 degree snowing/freezing raining morning where Walterboro, SC was the destination. In fact we encountered snow/ice/freezing rain all the way into North Carolina. Before leaving I put the tires to 50 PSI and checked them during the 5 stops we made. Each stop the tires had picked up about 5lbs and by the time we made it to Walterboro 13 hours later, the temps were in the low 50s. Left the next morning with Disney World being the destination. Temp was low 50's and when I checked the cold pressure of the tires, they were at 56-57 psi each. I deflated them to 50 and set out. (Not related to the tires, I had 2 lug nuts on one wheel give me a fit where they kept on loosening up alot. After several re-torques they seem to stay in place now.) Once again, 5 more stops (Gas and dog breaks) and they increased in pressure. Made it to Orlando at dusk and the temp was 80 degrees. Checked the air in the tires and they were up to 56-58 psi each. This was Monday Night. Left the tires alone until Sunday morning and checked them and the lug nuts before we were leaving for South of the Border. The Tires were sitting at 55-57 psi each. I deflated them and we left Orlando with 72 degree weather. Arrived at SotB at dusk where it was mid 50s and the tires were in the 54-56 psi range. It got chilly overnight and it was 51 outside when we left to come back home. Checked the tires and they were now at 48.5-49.5 PSI. Inflated them to 50 and headed home. Only made 3 stops this time and each time the tires were holding at 52 psi. The last time was south of D.C. and the temp was 68. Got home just after dusk, thanks to D.C. beltway traffic and when I got home the temp was 42 and the tires were at 51-52 psi.

My max speed on the way down was 61 mph. I didn't hit that at all as my truck has a variable speed warming indicator that dings annoyingly when a certain speed is reached. I had it set to 63mph and it never went off. On the way back home I did hit the 63 indicator quite a few times. Especially on 95 south of D.C. Max speed at one time was 65 for about 1/16 of a mile. Altogether I have 2k miles on these tires. A tad over 1950 miles just for this trip

I estimate I will probably have another 1k miles put on these tires by the end of this years camping season. Hopefully trouble free.

  • I have had Carlisle tires, load range "D" aired to 65 psi, on my last two 30 ft. fifthwheels. Been to west coast,east coast and to Alaska. No tire problems, but I cover them when not in use and replace them every 4 years.

    Happy Camping

    Reports like this would have more meaning if you had a profile listed with trailer info.

    On edit: I see you have a 2005 Komfort 271FS, trailers that size seem to do much better than heavy ones with ST235/80R16E's. Our 96 26 Terry with a single slide and 15" LRC Marathons went 7.5 years and a lot of miles on the original tires. Traded it in at that point. Chris

    I agree, very detailed report. However getting 2K miles on a set of new tires is not what I would call a true validation of the tire. Give us another report after they have 15K or 20K miles on them.

    One thing I would question is your depressurizing the tires after a run, back down to 50 psi. Everything I have read from numerous tire manufactures tells you to pressure them up to the proper pressure, based on weight and not necessarily the max pressure listed on the side wall, when they are cold and leave them there, as they are designed to withstand the increased pressure from road heat and friction, even when that pressure exceeds the max psi stamped on the side of the tire. Certainly an increase of just five or six psi is NOT excessive and well within tolerances. This is a procedure I have followed for several years with no issues. Every morning before I start out again with cold tires, I have found the tire pressure has returned to their original set psi over night.


    I don't think the tires will see that mileage as:
    #1 I am hoping to purchase another 5th wheel within two years
    #2 I normally only tow about 1,600 miles a year as most of our camping is within 150 miles of home.

    As for depressurizing them, I only did that before leaving for that days destination, therefore they were reset at "cold" pressure. I did not deflate while in the middle of a run. During the fuel/dog pit stops, I only checked the pressure. I apologize if my wording made it seem that way. After reading it above I can see how it was interpreted as such.

    I agree. After all the issues the past several years with the Carlisle tires I am not ready to assume this is a quality ST tire option yet. It would be nice and I hope it is so.
  • Who knows why the Maxxis ST tire failed but I doubt it was from poor manufacturing processes as so many of their competition is known for. Glad to hear that thus far the newly designed Carlisle ST tires are performing well, nice to know that there are some quality options besides just Maxxis when it comes to ST tires.

    I set my tire psi at the beginning of any RV trip and don't mess with them much afterward unless I see a reason to. Not worried about variations in psi as the tire engineers have factored in these occurrences when they spec a tire.
  • I also questioned your lowering the air pressure on a hot tire. tires pressure will increase as you drive and you should not lower the air pressure unless the tire pressure is high during a cold test not a hot test. rise in temp during a drive is normal. I bought a used TT last year and bought new over sized Carlisle tires and have had no problems with them either. One thing I've learned by selling TT's is the manufactures put the lowest rated tires on their units. that is why I went to a larger tire with a larger weight rating.

  • Good report...hopefully Carlisle has improved and will be another good ST choice.

    I am always skeptical when someone reports that a tire failed...ANY TIRE....and that failure becomes not just a failure, but a reputation.

    Example: we had the "highly hated" Mission Tires. They went over 5 years and many many thousands of miles without any problems whatsoever before we replaced them.
  • Good report on the Carlisles. I had them on my last FW, and they performed okay.

    But the Maxxis tire could have failed for a number of reasons, which may or may not be a manufacturing problem. Examples could be a leaking/defective valve stem, road hazard, inadequate inflation during installation, etc.
