heavy trailer tires, G614 - your experiences

[CHICKDOE]

our 5th wheel is over 16,000 lbs. it has two lippert 7,000 spring axles with goodyear G614 tires that are 2 years old. I inflate them to 108 psi. I have about 7,000 towing miles on the tires. I've looked at the tires and do not see any problems, but I am not the expert

we're thinking of taking a few trips starting in april. over the last week or so I've read several posts about heavy trailer tires. I know there are a million posts about 'china bombs', blowouts, and resulting damage to the trailer. I want to avoid that! there have been statements made 'to avoid problems replace your tires every 3 years'. and I have recently read some posts about the goodyear G614 tires where the poster claimed many years of use and over 10,000 towing miles. I can't remember from all the posts about blowouts if the G614's were mentioned or not.

so for those of you that have these tires on a heavy trailer what has your experience with them been? is there anything to look for this spring as we get the trailer ready for the trips? is there anything that can be done to avoid problems on the road? if anybody has had problems with these tires do you know why?

thanks for sharing

The G614 is in a class of its own, a true truck over the road tire, several in our group have run them for 5 or 6 years with no problems, just keep them aired up.

I've only had mine a year and not to many miles. I was there when they were mounted. It is quite obvious how stout this tire is compared to anything else when you can hold a Goodyear in one and a westlake in the other to feel the difference in weight alone. I have towed lots of trailers, enclosed and flatbed before my camping endeavor and never saw tire flex and roll like the westlakes that came on my thunderbolt. Peace of mind in my book.

One of the guys had a set installed at the campground on our last CTC trip, the G614 weighs 35# MORE than the E Westlakes he replaced.

My Cedar Creek is two years old and camper came with the Goodyear G614 plus 7,000lb axles. I have made two trips to Yellowstone from NC plus a lot more miles, the tires look brand new. I run somewhere around 110lb and I have TST 507 on the tires. I have a 32RL and I can carry 3900 hundred pounds but it's never close to that

The Goodyear G614 are the go to tire if you want to upgrade from any of the load range E tires that are coming out from the RV manufacturers.

Good luck.

I would run them at 110 psi an of course you have HD rims. If you look on the Goodyear website I believe under commercial tires, can't remember now but their is a table that shows how much the carrying weight goes down per lb. under 110 psi.Had my share of blow outs on e rated tires but never with the G 614. Great tires

How much the tire weighs is really not much of an issue.

How much weight the tire is rated to hold up, that is what is important.

The Sailun S637's are just as good at half the price.

2nd set of Carlisle and will stay with them. Never a problem over a lot of miles. No need for 110# air and would need new wheels as well.

I believe Goodyear warrants them for 5 years and will pay for damage to unit if they fail I don't believe Westlake will repair your unit

I try to buy things made in America, it seems not much is made here anymore. But I buy American when I can and the Goodyear's I like. I have Goodyear tires on my truck

Keeping tires PROPERLY inflated is the single best thing you can do for them. The best way to determine the proper PSI would be to have your rig "Smart Weighed". Smart Weigh gives you SIGNIFICANTLY MORE information than a CAT Scale. Escapees and RVSEF and two groups that provide this important service, both at reasonable cost (~$60). It's a one-time expense (unless you make SUBSTANTIAL changes). Bigger RV rallies often have one group or the other in attendance. After your rig is weighed, a trained rep will go over the results with you and advise what the optimum PSI inflation is for each axle.

The best thing you can do for trailer tires is install a TPMS that you trust. I have TST 507. They should come standard on camping trailers and trucks but they don't

I am assuming if the OP's fifth is weighing out at 16,000 lbs and 7000 lbs axles then he already has rims that are spec'd out at 110 lbs air pressure. Your fifth has a GVWR of a little over 12,000 lbs and the Carlisle's might be fine for it but not the OP's rig.

I have 614's on my 16K horse trailer. Five years and about 25,000 miles now and they still look new.

Had Carlisle on the last one at 15,500 scaled and they were fine. Those were LR G.

The heaviest Carlisle ST tires made are load range F with a maximum inflation of 95 lbs that I can see. I have had Carlisle, Mission, Kenda and Marathon ST tires on 12,000 lb fivers before and none of them ever lasted even with proper maintenance and air pressure. I switched to LT tires and never had another problem. My present 15,000 lb fifth came with Sailun S637 load range G Lt tires and they have been excellent.. They are now classed as an St tire but are are really an LT. They changed the designation so as to not have to pay import tax on an LT designation. To each his own. I am quoting my experience. Yours may differ.

As mentioned, the Goodyear G614 is an excellent tire. Many people upgrade from LR E tires to them.

As also mentioned, the Sailun S637 also gets excellent reviews and is a fair amount cheaper than the Goodyear.

The only upgrade from here to consider is moving to 17.5" rims/wheels and going with a commercial trailer tire. It's what I went with but I can't justify a blanket statement that everyone should consider/do it. For me, I knew we would be running heavy (16,800 at my last weighing) and fulltiming with a lot of miles. I also had space constraints between the 2 axles.
