Buying "G" tires

[rcflame]

I still like the TST monitoring system. When I have lost the tread, and the tire goes instantly flat, the alarm goes off, but there isn't enough time to do anything. The tire doesn't always go flat, but it's the tread flapping around that does the damage. It lets you know if a tire is going low, but have never had it happen before losing tread. I have had it let me know when the tire goes below the psi you have it set for. It has let me know when I have a leak ,etc. but I know of no system, or how you could have a system that would let you know when you have an instant blowout.

I have the other brand TPMS from Camping World. It works great, but be sure to install tha signal booster in these long trailers.

As to the question in temperature difference between 60 & 65 MPH I can say it's less than 1 or 2 degrees. The biggest differentiator in temperature is actually which side of the coach the sun is shining on. That a can add nearly 10 degrees to the tire temp.

The Goodyear G614 tire that so many of us are using is an LT tire. It should be more than capable of handling speeds up to 75mph...not that I run that fast, but the tire itself is capable.

That even bothers me more knowing that the tire is not a ST tire. If several people have experienced problems with those tires I don't think I would buy Goodyear. Several years ago when I purchased the Michelin XPS Ribs for my SOB fifth wheel, the Michelin website recommended those tires for the fifth wheel but now their site does not say that. I sent Michelin an e-mail on the 3rd asking why the change. Haven't received a reply yet.

May I ask why?

I've always considered the LT tire to be superior to the ST tire especially since all of our trucks are riding on LT tires. If the LT tire can't handle the fifth wheel, what's our choices?

Chuck,
Thank you so much for the explanation and link. This is something we WILL purchase before we hit the road this week!

The TST system doesn't have any type of signal booster & I have them on all 10 tires, works great.

Here is a nice article written about the differences between ST & LT tires. I think it needs to be noted that the RW trailers now are standard with the G rated LT tires.

The TST doesn't require a signal booster, I have the monitor mounted to my left on top of the dash wired to the external power and have never had a problem receiving a signal for any of the wheels on the truck or trailer.

Glad to hear you comment on the temp difference on the sunny side, I was wondering if others had the same issue. We have observed the same, about 10º difference.

[travelin' texans]

Same here on temp differences with the TST!!

That Michelin XP Rib is only rated for 3,040 lbs. That would limit your total axle weight to 12,160 lbs. I couldn't do it, and I don't think Michelin would stand behind a problem with the tire if it did happen. Of course, my experience they won't stand behind the problem anyway. They simply don't cover damage to the trailer.

So coming home today- about 40,000 people at the lake and it was a caravan of RVs and boats coming back to Denver. Counted about 4 boats on the side of the road with wheel problems. One in front of me burst into a white cloud, which is typical of an ST tire blowing its guts - but then shrapnel, and sparks until the gal got it stopped. I gave her plenty of room, and when I creeped by, the whole wheel was gone, not the hub/brake, but the wheel was gone. Couldn't tell if the studs were snapped. Is it possible the violence of a blowout could take the wheel with it? Maybe the tire got trapped in the trailer fender and caused the studs to shear? Which now I would have stopped, but with the Redwood on the back, Denver interstates are no placed to be pulled over.

True...which is why I didn't understand your previous post. Now I'm confused.

Our previous SOB 5th Wheel came with Goodyear Marathons.
The coach had a dry weight of 12,900 lbs, we took off the Marathons and put on "G" Rated tires during our first week of ownership.
We had our previous 5th Wheel weighed by the RV Safety Foundation during a fulltimers rally.
Our loaded weight was 15,700 lbs., sure glad we put the "G" Rated tires on it.
We recently traveled coast to coast just before we traded our previous 5er, no tire problems at all, actually no problems with our truck or trailer during the 10,000 mile trip.
Sure glad our Redwood came with "G" Rated tires.
Our Redwood's tire label (like others have noted) says the spare is a "E" but looking under the 5er at the spare tire it is a "G" tire.

IMHO, there is NO comparison between the ST marathons and the G's...
MOST forums have people taking off the ST's and putting on LT's and touting no more tire issues...

And given that our rolling 'hotels' have roughly 3 to 4k pin wgt,
the tires and axles typically do not need to be rated at full gvwr of 15 or 16k...

something on the order of 12k would be more like it, and that's 3k per tire.

on edit - do we have the LT or the RST tire ?

The Goodyear G614 is an LT tire.

Just noticed the TST unit on Camping World's site does come with a booster. I can run my system without a booster and it'll likely work most of the time, but any intermittent interference I would encounter going down the highway could interrupt that signal much easier without the booster. Think Cell phones, laptops, GPS devices, anything electronic in your, or any passing vehicle. Think about all the devices truckers like to run.

I believe it's this one:

I can't imagine an LT tire being better. If that were the case then RV manufacturers who use the G614 would likely go with an appropriately rated LT tire as they are much cheaper than these Goodyear tires.

[Blue Dogs]

The G614 tires are an LT tire! They are G rated rather than E rated. I don't believe there are any ST tires made with A G rating and a 3750LB weight rating in a 16"

Tst calls it a repeater instead of a booster. I pull a 36RL with a extended cab 8'box and have never had a signal problem.
