Goodyear Endurance

[Mikelff]

I recently replaced all 4 tires on my Montana 2018 358BH with Goodyear Endurance ST235/80/R16 tires after having an oem tire loose the tread. Just didn’t feel safe with those old tires after having that experience. Luckily, it did not blow out and i limped to the truck stop and had the spare put on. The guys at Discount tire said these Goodyear tires are more than adequate for my rig. This is a big rig at 41’ . I always check cold tire pressure before I head down the road. I am fairly certain I am not overweight, but plan on going to the scales fully loaded to check for sure. My research showed that these Goodyear tires are among the best out there. I am interested in hearing any experience with these tires. I am also high in the front end and have hitch and pin on lowest settings so can’t make any more adjustments that way. Can only go with a taller tire next time. My Chev 2500 has been re-certified and is now basically a 3500 with the new leaf springs. Will have to see how the tires wear from here.

For those with a 3/4 ton please explain the re-certification. I think that would be good info to share !! Thank you

Tony, here is a photo of the new specs on my door. I know not many spring shops can do this. They have to be DOT certified and there are other regulations they have to follow, which I know nothing about. I know the basic difference between a 2500 and a 3500 with chevy is a leaf spring. Thats it. Try to find a 4 wheel 3500. I looked for months and could only find stripped down work trucks, so I went this route which worked out well. I can still get my truck in the garage!

Let's see what "more than adequate" means. The Goodyear Endurance ST235/80/R16 is an E1 (10 ply) tire with a Load Index of 3417 and weighs 40 lbs. To start, the axles are 7000 lbs and your tires only can carry 6834 lbs. That doesn't meet the basic standard much less any 10% reserve capacity.

The preferred tire for a Montana is a Sailun 637 . They are G range tires (14 ply), weigh over 60 lbs. (much mare material to them) and carry a load of 4000 lbs each.

There is no way a GY Endurance tire belongs on a Montana.

The Endurance is a good tire, but not for a heavy trailer. Assuming you don't overload your rig, based on Keystone's numbers, you'll probably be alright, but you're not leaving a lot of or any wiggle room.

Exactly what Carl & Dick said. That camper is WAY to heavy for those tires. I suspect you will continue to have tire issues. If I was you, I would cut my looses and replace them with the Sailun s637 0r Goodyear G614 ASAP. You can resell your endurance tires easily on craigslist.

Make sure your rims are rated for 110 psi air pressure.!!!!

My rims are the OEM rims that came with the rig new. I will check with Keystone tomorrow to see what they say. Three of the tires I replaced were put on new at the dealer a year ago last April, and were the same size and rating as I replaced with the Goodyear. If Keystone says I need G rated tires I’ll have to replace them and see if I can sell them on Craig's list. I’ll see if Discount Tire will work with me at all. Not more than 10 miles on those tires. Thanks for the info!

Listening to what Keystone says is a Kin to listening to your dealer telling you your half ton truck can pull that Montana. Lol

There is a "catch 22" with ST235/80R16 LRE tires. Most of the Original Equipment tires have a maximum load rating of 3520# @ 80 PSI. The GY Endurance tires have 3420# @ 80 PSI.

There is nothing wrong with the size and load capacity of your OE tires. When serviced to their recommended cold inflation pressures they are providing more than 15% in load capacity reserves. RV trailers are notorious for having a single wheel position carrying much more weight than the others. Maybe you have found yours. I recommend a trip to some scales that can do individual tire position weights.

OMG


the 614's will only give him 3750 and are lt tires, he's got 3420 with the endurance.

The endurance ST255/85R16 would give him 4,080.


3420 x 2 = 6840. so he is 160lbs under the max 7,000 axles.



I am sure the dealer did not sell him tires that carried less than the tires originally on the rig.

Well you have two choices you can either listen to the seasoned Montana owners on this thread and many others about tires and either get the Saoluns or the good years or you can roll the dice and choose any other Tire you want. Just saying.

And if you believe a dealer wouldn't sell you an incorrect product for its application you better think again. They could care less they would let you drive out of that dealership with any camper you want as long as it would hook to your truck..

There is not a Goodyear tire that belongs in this conversation. You mention the Endurance ST 255/85/16 , to start they don't fit the wheels that come on the Montana's ,even if the clearance would work. So again ,we need to leave the Goodyear tires especially the Endurance out of the conversation .

E-rated tires should NOT be part of the Montana line.

I'll second that deduction

What has "E-Rated" got to do with it? All ST & LT tires have load capacity ratings by letter.

ST225/75R15 has E & F load capacity ratings.

[beeje]

With the exception of a few most Montana's IMHO are too heavy for E rated tires...... do you want peace of mind never having to worry about a blowout but the sailuns on.

I think what they are saying is the LT, and ST E rated tires don't meet the weight ratings on these Montana fifth wheels, especially the RIVA specs that you have been reporting with needing 110%.

Pretty sure the new Montana fifth wheels do not come with an E rated tire period, not sure what the OP has , probably a High Country, and at 41' I have to agree he would be well served to get a G rated tire, providing his wheels are rated for 110 psi.

That Endurance would be the last tire I would put on that 41' fifth wheel .He needs to listen to what others are telling him, or his troubles will continue.

Sorry i guess instead of E-rated i should have stated 10 ply.

I have to agree with you on that one! I have Contender Premiums on my 3610, 110 psi, load range G, 14 ply. I blew out 2 Goodyears in one day!

[socoinc]

Carl explain to me why a Goodyear Endurance G614-235-85-R16 doesn’t belong in a Montana 5th wheel. It’s 14 ply. Granted it’s a little more than that china tire. I could go on & on but I’ll get kicked off...
