New Goodyear Tires

[VT Wanderer]

Tire News - Goodyear now makes a new ST tire - for my AS it would be on a 2014 Flying Cloud, 27 ft. with ST225/75R15. The tire is called the Goodyear Endurance. Here are some of the stats. Load Range E - Max Load 2830 lbs. - Speed Rating 87 mph - Max Inflation 80 psi - Made in USA. These stats are quite different from the GYM.

Sounds interesting. There were some previous discussions about it:

Is this Tire Rack ST225/75R15 -- Serv. Desc: 117/112N what we are talking about?

Good find, thanks VT Wanderer!

If they are actually making a 15" E rated ST tires - does a 65 PSI (instead of the 80 max) equate to a D (2540#) or would that be bad for the tire?

I'll be keeping my eyes on these for the next time I need tires for our Avion 34W...... will be a few years.

FYI I could not find any info on the Goodyear site, so a call to Tire Rack if you have one nearby might be a good start. Please let us know if you get any further information.

Thanks,

Ah .... Mmmmmm ...... How to say this?

The fact that some of the new Goodyear Endurance tires are Load Range E is just a measure of load carrying capacity - sort of like the difference between a 5 gallon can and a 6 gallon can. It has nothing to do with whether or not the new tire is better than the old tire (the Marathon).

In my opinion, many travel trailers came with marginal tires and needed an upgrade in load carrying capacity - one of which would be a move from Load Range D to Load Range E.

Yes - I'm aware of the concern with STs and overloading. I had the 15" GYMs and went to the 15" Michelins. This effectively reduced my total carrying capacity by about 20% - however, even de-rated, the Michelins still have 25% "headroom" on a 6000# loaded for camping trailer according to CAT scale tickets.

As these Goodyear Endurance ST tires (should we call them GYEs to distinguish from GYMs?) are made in America - and to my untrained eye look like a much improved version than the GYMs - I was asking whether using them at 65 PSI gets you the equivalent of the original 2540#/tire - and if so, whether it's harmful to not use it at max pressure. I get that the jury is out on these tires. When ready to replace the Michelins, I might go with the 15" D rated LT Nokians - just curious about these American made GYEs as well.

currently tracking the Nokians for our Bambi.

GYE's look promising and will track comments.

Just a couple of follow-up FACTS. This is the information that I received from 2 major companies. 1. In my conversation on 1/16/17 with a Tire Rack advisor, he stated TR does not recommend the use of LT or any other non ST tires for trailers. 2. Several months ago I contacted Michelin Tire Co. (headquarters) and was told that only tires labeled ST should be placed on trailers. 3. As for the question of inflation on the new Goodyear Endurance, Tire Rack recommends following the inflation information that is given in your Airstream manual or labels.

There you go again with those pesky facts from experts......

(Kind of like tow vehicle ratings...!! LOL)

We just had 2 separate blowouts on the road with 4-5 yr old Goodyear 16" on our 2007 classic with slide. Replaced them with Firestone 16" now I'm worried if we made a smart choice. Michelins weren't available.

From Nokian:

Thank you for contacting Nokian Tyres.

Yes, maximum inflation is 80 psi. If you were to run at 65 psi, max load would be 2335 lbs for single or 2150 for dual application.

Hope this information is helpful.

Regards,

Nokian Tyres

and they are " E " rated tires with a speed rating of 112 mph

Thanks, RLS - just to be clear - your answer comes from Nokian so I'm assuming they're talking about their LT 15" tire there - not the GYE (Goodyear Endurance 15" ST tire made in America) - yes? Thanks!

SSM, This is what I've go on my radar. Just not comfortable re the GYE's based on GYM's history. Maybe they are greatly improved but t took way to long to finally release the GYM 2.0

Nokian Rotiiva AT All Season LT235/75R/15 116/113S LR E (2760lbs)

not sure of the size discussed above but otherwise is a match with the E and speed ratings

This link shows what must be done to use passenger tires safely on a trailer.

Skip down to section S4.2.2 - Tire load limits for multipurpose passenger vehicles, trucks, buses, and trailers.

Yeah, that's why I'd never buy a Ford... you know, that whole Pinto disaster.

Understood. I'm currently using the Michelins (15" P rated). Those Nokians are actual 15" LT tires (which is rare) and they have higher load capacity than the Michelins. I'm interested in the potential success of the GYEs - looking forward to learning more. I have another year left (maybe 2) before swapping out. We'll see.

Installing the nokians this week. Traded my 25 fc 2015 for a 2017 fc, had nokians on that trailer too. Not even thinking of another brand. Purchased from simpletire.com

It is the same tire
