Someone posted earlier that their wheels are rated for 3750 lbs but wondered about air pressure. The link provided by exav8tr reads that at 110psi the G614 tires will support 3750 lbs. This should mean that the wheels in question will support 110psi to get 3750 lbs of capability on that tire.

Like Phil, I always wondered why the G614 tires were designated type "LT" while specific for use in trailers. I would guess this means that this ST tire would get the benefits of LT duty tires. The vertical strength and long term storage of an ST tire with the durability, flexibility and speed rating of an LT.

Hopefully, Lonnie might wander by and shed some light.

One should note, that just because your tires can handle 110 psi doesn't mean they have to have that much in them. Mine are set at 95 psi to handle my weight. It is important to know your weight so you can run the correct pressure in your tires. Even 80 psi on your E rated tires may be too much. For example: My truck tires say max pressure is 80 psi, however, the tire loading chart on the door pillar has much lower values posted. I use the posted figures (now) to air up my truck.....(Thanks Lonnie). I was using 80 psi and what a rough ride while not towing. I have seen the error of my ways.....and my back says thanks.....

Goodyear G614 RSTs went on the Monty today. Those tires have some meat to them. The Goodyear Marathons that came off the unit weighed 55 Lbs each mounted on the rims. The new G614s weigh 80.5 Lbs each mounted on the rims. Wow! I guess the Monty weighs 102 Lbs more now.

The printed info from the tire shop for the GY614s does not even mention LT anymore. They do say they are for demanding trailer applications.
It appears to me Goodyear is promoting them mainly for trailers.

Thanks to LonnieB for providing me the correct numbers and names of the all metal chrome valve stems. Lonnie always comes through for us.

i just put on a set of g 614 on my 3400 rl.called the manufacture of the steel rims and they told me they are rated for 110 psi.that was from the rim manufacture and not keystone.

Hey Hoover, I'm in the same situation. Our 3400 was weighed last Fall rally and all within tolerances except pin weight. We have the Duravis 500's and are a really good tire thus far. They are wearing well, with about 7-8000 miles so far. Lonnie really helped us on various brands and types too!
Dennis, did that guy with the scales at the rally ever catch up with you?

We also recently installed the G614's all around plus the spare. All are aired to 110. At last Fall's rally we had the rig weighed at each wheel. The heaviest requires 105 psi per the Goodyear chart. So I went to 110 so if we lose 5 psi before I catch it we're still at the correct psi for the weight.

We went to the G614 because of about $2100 damage (plus the tire) from a blowout on one of those darned Chinese tires. That's two of them blown this calendar year and more than I can count during all our travels. I hope the G614's eliminate that problem.

I was just looking at a Keystone Big Sky on Lazy Day's website...looks like the G614s is coming standard on that unit????

Jim, Goodyear G614RST, LT235/85/R16 Unisteel, Regroovable, Load range G, Max pressure 110psi, Single tire rating 3750 lbs, dual 3415 lbs, sorry, not sure of the exact width, doesn't say on the tire, but I put them on my stock OEM Tredit TR-6 wheels. I, too, went thru the Manuf for the recert stickers and a letter to show to the tire guys that they have been recertified.

Thanks Phil I'm printing this off for my tire change. I now have... 8 month's 13 days 19 hours and 16 seconds...
This is subject to change, just depends.
I figure getting them about a month before we go.
Phil, did you check the date codes to see if you got 'fresh' tires?

Michael, yes, they probably started doing that after our 09 Big Sky had tire problems at 2000 miles. Keystone would not even talk to me about what I should replace the Chinese bombs with. Told me they only recommended replacement with the original equipment. So besides eating $1800 in damage to the BS, I had to buy new rims and G614's that should have been on there to begin with. Learned a few BIG lessons real fast!

I have 2008 3400rl with 110 psi rims I'm running G614 but only run 90PSI you don't have to run 110 PSI. If you need to run 110PSI then rig is probaely over loaded. When I weighed my rig the trailer axels were 12,000 Lb's or 3,000lb's per tire. I had to completely replace my axels and suspenion with Mor-Ride IS system. My axels were bent and spring were bad and had all ready replace one Mor-Ride part in system that came with my trailer and 2 complete sets of tires. that why I went to Mor-ride IS system. I have over 30,000 miles on my rig.

Under the heading of "curious," I have read many posts where the writer states they are running their 110psi tires at less than 110psi...for whatever reason. I have also read that one of the reasons a tire will heat up and fail is underinflation. Further, I have read that this failure might happen at 12% underinflation. Well, running 110psi tires at 90psi is 18% "underinflation!" Of course, there are other examples of this "underinflation" issue. My truck, for example: I have the same tires on front and rear, yet I am supposed to run the rear tires at 80psi and the front at 65psi. So, are the front tires 17% underinflated? Is it any wonder with these conflicting facts that we do not have a firm grasp of what our tire pressures should be?

Most of us are inflating the tires according to Goodyears tire inflation tables which specify pressures according to load. A tire is not "under-inflated" simply because it is not inflated to it's "maximum" pressure. I run my 614's at 100 psi because the Goodyear inflation table tells me that is what is required to comfortably carry the load that I have on them. If my specs for the tire required 100psi and I chose to inflate them to only 90, then I am indeed 10& under-inflated and should fully expect problems to arise. Keep in mind they are not 110 psi tires, they are 110 psi maximum tires!

Thanks for the responses...with the numerous tire issues reported on the MOC website, I guess I am a bit "gun-shy" as far as tires are concerned. I do not want to be another person reporting exploding tires and a damaged coach. Again, thanks for your information.
