16 inch truck tires for the RV.

[roadglide]

I was talking with a guy about tires at the RV park, this guy said I should get rid of the trailer tires and go with 16 inch 10 ply truck tires because the truck tires are better built for safety reasons. It made cents to me because how often are recalls for trailer blow out and someone one gets killed? this full timer said he hasn't had a blow out with truck tires.

According to the specs on your rig, you are just under 7.000 lbs on each axle, so LT tires will not work, they are only good for 3042 lbs per tire. The ST tires that probably came on your rig probably just made the specs for your load. You will be better off going with a Goodyear G614 or the equivalent Sailun tire, or something similar that is rated 14 ply, and in both the tires I mentioned, are all steel cord and will give you very safe service, as they are rated 3750 lbs per tire, which gives you the full rating of your 7,000 lb axles.

There again the Carlisle 3960 are trailer tires, I think trailer tires are skimped on for reinforcement along the line or there wouldn't be so many premature blow outs.The G614 Goodyear is a heavy duty truck tire and both brands are sold at discount tire or Walmart where I buy my tires.

Well here is the thing about the so-called "premature blow outs". What is the other side of that blow out story? Were tire pressures being properly maintained? What speeds were those tires subjected to? I would be willing to bet that a good number of these blow outs were due to negligence on the part of the owners. Fun fact, there isn't a trailer tire on the market rated for more than 65mph. I see people pulling their trailers at 75 or 80 on a regular basis. I bet these same people didn't bother to check their trailer's tire pressures before leaving on that trip. Low pressures combined with over speed equals blow outs. Just sayin.

ST tires have stiffer sidewalls than LT tires reducing sidewall flex which is a contributor to sway. I've been running Carlisle tires on all of my trailers for many years and countless thousands of miles without a single issue. That includes a 1400 mile trip with (yes, I'll admit it) an overloaded car hauler, about 200 lbs over per tire. The car hauler was purchased specifically for my corvette, but I had to transport my son's Jeep Grand Cherokee after an engine failure.

A lot of people have had success with Ribs and G614s, to each their own.

Do yourself a favor and as stated above look at the Sailun S637, this tire is a beast. The supposed "stiffer sidewall" on the ST tire can't even come close to the S637. We have a set and I can honestly say that the sidewall is at least 1 inch thick. Our original POS GY Marathions weighed 36 lbs. each .... the Sailuns were 62 lbs !! You can find them on ebay for around $195 or so by a seller that goes by "rustybore" ....and it's free shipping. ooop's my bad, just looked on ebay and "rustybore" has them now for $210 each free shipping.....still worth every penny.

Your correct I checked my tires st 235 80 /16 have a load rating 3520 lbs with 7 thousand lb axles. I should be good with the tires I have . On the cat scale loaded for a trip the trailer axes are under 11000 lbs, with the Harley in the garage, took weight off the truck.

If your axle weight is 11k:
Your tires are rated for 14080 in ideal conditions. You're at 78% of rated capacity on those tires, assuming that's how your drive fully loaded.

Your rig probably isn't perfectly level, so I'd guess that you have at least some front to rear and left to right imbalance. That puts your at least one tire into the 80%+ of rated capacity range.

Under-inflate / over-inflate and you can see how things can get out of the "good" zone pretty quickly. There is also the theory that tires degrade at 5-10% of rated capacity per year.

What is the brand on your stock tire now? .

What Seabee said. We also have gone to Sailun tires and they seem to be great so far. I have been told that truck tires are not a good idea for trailers unless you never make any sharp turns. They are not made to scuff sideways when turning.

I have been RVing since the early 90's and have experienced numerous tire issues, separations, blow outs and side wall break downs. The last 2 RV's I have owned are large campers and I installed LT over ST tires and have had great luck with these tires. I purchased a new camper last year and took the 15" ST 8 ply tires off and replaced with 16" BF Goodrich Commercial TA 10 ply truck tires and this sure gives you piece of mind. I have ran these many miles on the last 2 campers and I have not experienced any tire issues since. Note that if the tires are not rated for the load then do not install them, also always ensure they are inflated to the max by the manufacturer.

Happy Trailering!

I was at CW a couple of weeks back and the larger Cougar and Montana 5ers all had LT tires on them.

Got my Sailuns for $710 delivered to my front door from Simple Tire. Rated for 75mph and miles of confidence.
