Goodyear G614

[sreigle]

The TR-6's are rated for 3750 lbs and 110 psi. Mine have a sticker on them saying that. Others have it stamped on the inside.

I used the Goodyear charts and found I need 105 psi in the tire carrying the most weight. So I run 110 psi in all four to give me a little margin for when changing altitude or temperature. I've only put 6k or7k or so miles on them so far but they've been perfect. It's been a long time since we've been able to go that many miles without a tire problem. I'm liking it.

After 12,000-15,000 miles on my G614's, I gave them close inspection. The wear is even. The tread looks great. The sidewalls are not scored or showing signs of aging. I am very happy with the tire. I bought them in late 2007, so they are aging and will need to be replaced before our next major excursion After my early experiences with other tires, having 3-1/2 years and over 12,000 miles without blowouts or tread failures is blissful.

Thanks Stiles, posts such as yours serve to validate my decision to go to the trouble and expense of having the Mara-bombs replaced with the 614's when we purchased the new rig.
Bingo

My only complaint with the G614's is I wish they had some tread on the outside ribs rather than being smooth. It would be much easier for me to judge edge wear if there were those tread indentations to look at. But I'll live with that for the peace of mind these tires are giving me. We're over 6,000 miles on them now with nary a whimper. I like it.

After reading all these posts, I guess I should be happy that I've only had one blowout (no damage) after 26,000 miles of running Marathons. Unfortunately it's two sets of tires and due to uneven wear I'm in the position to bite the bullet and buy a new set (after I get the axles and rims straight). With all this wonderful advice, I'm thinking of going with the G614's. Did I read that Sam's Club can do these???

We have over 6,000 miles on ours...no sign of wear. I keep 110 psi in them. Had Missions on it before...glad we did the change over.

I think it depends on the Club. We had our dealer to take the rims to Sam's Club to get the 614's mounted.

I am taking my last Missions off shortly. Had failures with three out of my 5, but not due to defects. Road hazards. I am getting ready to switch to the G614s If I can get my rims re-certified. Can't find a TR6 stamped anywhere on my rim - front or back. Only the "3750". I guess I could pull the spare and take the tire off of it...

Where on your rims is the 110 psi marking??? My 2008 3400RL has aluminum rims,which look like all the other rims on the Montana fifth wheels in 2008 , and the only marking's I can see on mine is the weight rating which is 3500 lbs,and that does not tell me they will handle 110 PSI..

On the inside of the rims on one of the spokes. Put G614's on mine today. Don't think you can see the markings with wheels mounted on trailer. Heat is your enemy. I keep a heat detecting gun in my TV and check all 10 tires frequently. any distinct increase in temp is bad. Low pressure causes walls to flex...flexing causes friction... friction causes heat. SAFE AND PROPER EQUIPT. CAUSES SAFETY AND PEACE OF MIND. Heat gun has red laser pointer, so you are sure to get the right readings. It also works for hubs, so you know of bearing troubles also. Gun cost about $40.00 at Advance store.

I'll drop the spare and look.

Here are the new ones:

I had many conversations with Tredit regarding their rims. I had a cracked spoke on one of the rims. The ones that come with the 2008 3400RL are rated for a max of 80 psi. For awhile Tredit was issuing certifications stating the rims would handle 110 psi. They have backed off from that and now insist they're only rated for 80 psi. When I put on G614's, I replaced the rims with 110 psi rated rims - from Tredit because they gave me the best price. I had to replace one anyhow, so I upgraded at the same time.

Good work Ozz...you might want to say something about the heat sensing gun as it was designed for A/C work.

[dsprik]

Thanks, Ozz. I will drop the spare. Too hard and too dirty to see anything on the other tires. In a long shot question, I don't suppose one can assume that a "3750 lbs" stamp automatically translates to 110 lb rating? I have that stamped on the front of my 2007 3400 rims. Doubtful I guess and a professional tire dealer would probably not go solely by that anyway I would suppose?

[Ozz]

I would think that rating would cross to the H.P. tires. I also would think they would.
The heat sensing guns- Infra-red, sense the surface temperature of matter, the pro models are pricey, but you can get small one very reasonable. I bought a few at Radio Shack a year or so ago for my commercial customers, I think around $20.00. Nice for checking tires, bearings.

On edit: Looking back a page, Larry mentioned the use of the heat gun, good advice Larry.

Good day all. After just finishing our first rally, 2011 Fall Rally, knowledge has come rolling at us so quickly that it is difficult to grasp it all. The prime objective should be to make sure you have the maximum tread contact with the road. Period! to make sure that happens you must make sure the tire pressure matches the tire as well as the load it carries. You should be able to find this info at your tire makers web site, if not then get rid of those tires!I was schooled in auto mechanics and worked as a mechanic for more years then I should have and as the the Tredit representative went through all this all that classroom knowledge slowly came to the surface. We had our rig weighed at the start of the rally with 3000 being our highest tire load weight. Then after all the personal details of tragedies past as well as those that happened coming to the rally we made sure when we left that our near to new, 2011 3400RL, left the rally proudly wearing a new set of American Made Goodyear G614,s, as well as a temp and pressure monitoring system. We went with the monitoring system that was recommended by Tredit, the "Valor TPMS-203". Took pretty much a whole day to get this taken care of but in our minds we could find no way to NOT make a best effort NOT to get stuck on the road do to something we just night have been able to avoid.
At 3300 lbs of load the single mounted Goodyear 235/85R16 G rated tire should be inflated to 90 lbs. The only reason to carry 110 lbs would be that tire was carrying the maximum load of 3750 lbs. Again, this is to insure you get the maximum amount of tread on the road for best wear, temperature control and handling.

Thanks JazB for that great post. I replaced my bombs with the G614's after one trip out. Discount Tire inflated to 90 psi as that was the max their compressor could do. I was planning to increase to 100 psi but after reading your post I think I will leave them at 90.

Glad it all worked out good for you. it was nice to have met you and been your "neighbor".

See my post on the thread "Dead Marathon- variation on a theme" for my comments on the Marathon issue after talking with a Keystone manager, and the fact that there is a second plant making Goodyear G614s in China!

[twrastall]

The male customer services rep at Keystone that I talked to told me all the Montana's have 80 PSI wheels except the Big Sky. I found this was not true. According to Tredit Tire, the folks who install the tires and wheels on the Montana told me that anything manufactured in 2010 and later have the 110 PSI wheels. You would think the Keystone rep would know this. I got this same guy before and have found him to have a bad attitude. The woman customer reps have been much better.

I just upgraded to the Goodyear G 614 tires. I ordered steal valve stems from Tredit Tire to match my Montana wheels. The stems I received did not fit the whole in the wheel. Turns out there are two different size holes for the valve stem for newer Montana Wheels 2010 to 2011. The stems I received leaked.
