Enough already with these foolish comments. I don't know if these a re jokes at this point or what, but they are down right moronic. Every tire you ever owned for your street vehicle has a tire rated for well over 65mph, do you drive at the tires rated speed often? EVER?

Or may be some of you are implying its not ok to have a ST tire rated for 75, 87 or more??? This is a joke to you? Its meaningless?

Hmmm. Why then...do so many on here feel the need for the highest LOAD rating possible on their tire for NO OTHER REASON than the belief is wont fail as easily as a lessor rated tire for the same load. High load ratings does not have a direct correlation with failures, but people think it does.

So when it comes to speed ratings...OHHHH...the sky is falling? I cannot buy a higher speed rated tire and feel better about traveling at 70-75mph knowing the tire was designed and tested for these speeds? There is something wrong with a well built tire that can handle high speed...even if I'm not driving that speed???

Many claim to switch to LT trailer tires to allow for higher travel speed. Yet I don't see the same amount of flack I see here regarding ST tires and speeds over 65mph. What a joke.

I would be a bit concerned about my safety towing a trailer at 106 MPH. :E

Now you're just being trollish.
It wasn't that funny the first time because a good bit of folks do have a lot of interest in their tires and their safety.

Go to your website with the ST 106 MPH rating
Copy the url (www.XXXXX) in the address bar of website
Open the RV.NET 'advance post' then click on the LINK Icon (small box with World and chain link)
Paste the copied url into the popup box.

Then we ALL can check out those high speed ST tires


OR

IF that is too complicated
Just copy/paste url address in your next post and someone will make a clicky out of it

I do not know how to paste a web site up here to make it easy , I have found two ST tires with 106 MPH ratings , and many , many with more than 65 MPH .

I'm going to get me some of those "N" rated tires, then I can get to the camping area so much faster.

And here's the rest of the cut and paste from that same section. "How fast can I travel..." on the Carlstar website:

Please remember that speed ratings are test speeds and not recommended driving speeds. The ratings apply only to the tire itself, and not a particular vehicle. The speed rating does not mean that the vehicle can be safely operated at the tire's rated speed.

We recommend driving no more than 60 mph when towing a trailer. Please always drive at a safe speed and abide by the posted speed limit.

I wonder if that same FAQ has been distributed to the Bassmaster Tour group. If they tow their trailers anywhere close to how they drive their boats, Carlisle was probably replacing a lot of tires. :B

Here is a quote from the official Carlisle website FAQ.

How fast can I travel on Carlisle trailer tires?

In the past, most trailer tires were rated at 62 or 65 mph. Today, some of our tires are "rated" (speed symbols) at 87 mph (N), some at 75 mph (L), some at 65 mph (J: ST tires) and some at 62 mph (J: non-metric tires).

The point of the thread has nothing to do with how fast you should tow your trailer or what is safe to do with your trailer. The point is that many folks insist there are no, none, nada ST tires with a speed rating over 65 MPH. That's not true. It doesn't matter what the myths or "common knowledge" says, there are in fact ST tires rated by the manufacturer for speeds over 65 MPH.

Not all ST tires are used to tow a travel trailer. My boat trailer has ST tires and you can bet it goes over 65 MPH often.

It does appear that Amazon has a misprint on their listing for the Carlisle tires and the OP was aware of it but decided to post anyway. However, that doesn't alter the fact that some ST tires can be used at speeds in excess of 65 MPH. Anybody who makes the blanket statement (and many do, especially when making the LT arguement) that ST tires are limited to 65 MPH are just simply wrong.

Out of interest can you point out a link on a ST tire mfg website that shows an ST tire with a speed rating higher than 65? I believe you, but on every mfg website I've checked I can't find any info on ST tire speed ratings given by the mfg.

Or a picture of an ST tire that shows a speed rating other than 65mph.

Not that I travel more than 65 with our trailer, but a increased speed margin would be nice.

The link is on page 5

1) well, the amazon link with speed ratings is completely bogus. pick any rating you want and all the tires come up

but goodyear and towmax show 75mph speed ratings on the latest tire list.
2) Goodyear Marathon website and data shows the marathons having a 75 mph speed rating. the list the tires using the new rating notation of 3digits/letter with the 3 digits being the load rating and the Letter being speed rating. speed rating on all the marathons I checked was "L" which is 75mph BUT with a reduced service rating (load capacity) in one example 113@65, 108@75. Likewise with Towmax
3) Towmax is the same, "L" speed rating, similar change in load capacity.

I've emailed maxxis and carslie asking if they have any ST tires with speed rating greater than 65mph. once I get results I'll post.

so at least the latest marathons and towmax do have a speed rating of 75mph with reduced load capacity.

ok here is what I heard from Maxxis

here is the response I received from Maxxis regarding the question if they had any st trailer tires with a speed rating greater than 65mph

Bill,
The short answer is no, but neither does anyone else.
According to the Tire and Rim Association, the U.S. tire industry specification authority, inflation pressures and load specifications in general for any ST Radial trailer tires, without a service description, regardless of the manufacturer, are designed and rated at 65 MPH. If the speed is higher than 65 MPH, the pressure and load need to be adjusted according to the following guidelines:
From 66 to 75 MPH – the tire inflation pressure needs to increase 10 PSI (not to exceed the maximum PSI the tire is rated for) but requires no load adjustment.
From 76 to 85 MPH – the tire inflation pressure needs to increase 10 PSI (not to exceed the maximum PSI the tire is rated for) and load should be reduced by 10%.
We hope this information is helpful. Thanks for your inquiry and interest in Maxxis Tires.

So, I guess the answer is yes BUT. at least with the Maxxis, since they state you can't exceed the max sidewall pressure, above 65mph, the load carrying capacity of the tire drops, but yes you can exceed 65mph IF you have enough load carrying capacity margin in the tire. And with goodyear and towmax they lower the service rating at 75mph, probably matches what Maxxis relayed
