Tires

[Jubal]

What company manufactures the tires that ETI is currently using and what is the maximum speed rating?

[J Mac]

Carlisle 15" ST205-75R-15
Don't know the speed rating.

[santacruzer]

ST Trailer tires are rated for a maximum of 65 mph, I believe, as an industry standard. Someone correct me if that's wrong.

That's exactly what I've heard over the years. Yes, there are other tires for much higher speeds, but they're not ST trailer tires.

Beats me, but Tire Speed Rating with Kal Tire gives an explanation of speed ratings.

Chart from Kal Tire site and note none have a rating that low:

That "R" is not the speed rating, it's for Radial.

[gbaglo]

I looked on another site and it gives the Carlisle 15" ST205-75R-15 an "R" speed rating.
The speed rating, I gather, would be the last letter in the string. ie. Carlisle 15" ST205-75R-15R ( but we don't have that info, other than from a site selling the tire ).

I don't think I'd want to tow a trailer at 106 MPH. (following the Kal Tire chart)

[jamman]

65mph (104kph) except ...
About half way down the page: http://www.tirerack.com/tires/tirete...jsp?techid=219

[gbaglo]

I was reviewing the Kal Tire chart and note that the rating is for a P or passenger tire.
Perhaps an ST tire with the same R rating would have a different speed rating?
One would think it means the same no matter what type of tire.

Excellent.

ST205/75R15, but we get the idea.
Some models have a larger size... ST205/75R15 as I recall.

There is more than one model of Carlisle tire in those sizes, although the commonly available model is the Radial Trail RH.

Earlier, I believe that ETI used Goodyear Marathons.

Yes, that is the default speed rating for Special Trailer tires.

An ST tire can be rated higher, but the vast majority are not. I agree that higher-speed tires are likely other types.

The Kal Tire chart is incomplete, omitting ratings below that which would be found on car tires.

True - for quite a while one of the tire retailer sites incorrectly displayed the "R" for radial construction of ST tires as the speed rating.

That's an error, probably due to bad computer code misinterpreting the spec with the speed rating missing, and picking up the R for radial construction instead.

Was that Discount Tire? They had this error but corrected it - eventually - after I reported the problem.

It would be "ST205/75R15 R" (note the space before the speed rating), if anyone made an R speed rated ST tire (but they don't). There should also be a load index before the speed, such as "ST205/75R15 101R" (if it had a load index of 101 and a speed rating of R... which again, it won't).

I believe the speed ratings are the same for other tire types; the confusion arises from people trying to reconcile an incorrect "R" speed rating with the low speed rating they know ST tires must have.

[Brian B-P]

So... did anyone notice which Carlisle tire model is on their Escape? Does it have load and speed index numbers and letter after the size shown on the sidewall?

[Brian B-P]

How to Read Speed Rating, Load Index & Service Descriptions from Tire Rack gives a decent explanation, and shows lower speed ratings than the Kal Tire chart... but still not down to the "J" or "K" rating of typical ST tires.

I'm going to wait until you guys sort this out. I was going to replace my tires this summer, but I'll do it next year.

If you're waiting to find out if ETI supplies speed-rated tires, I doubt there's any reason to wait for this discussion. It's likely that any ST tire sold in Canada has only the default 65 mph speed rating, and the higher-speed alternatives to ST will not be what ETI is using.

Discount Tire sometimes shows a Carlisle tire with an N speed rating, but the Carlisle web sites don't mention its existence. I think it is the Radial ST (not the Radial Trail RH), but you can only see the specs on their website when they have it in stock.

[thoer]

I wonder if Reace made the change from Goodyear to Carlisle due to Carlisle being better quality? Or if they are both approximately the same quality, that a better price is available for the Carlisle?

[J Mac]

This is a lot of conversation about the speed rating of various tires. But, what's the hurry. If you get tired, or it gets late, take a nap. Or better still, leave for your destination earlier! Sure, it's good to know the specs of your stuff but slow and steady wins the race. (or at the very least gets you there).
YMMV....and it certainly does.

I felt uneasy trying to maintain the 80 mph speed allowed in some western states, I never intentionally exceeded 70 mph any time due to trailer tires and the fact my truck tires are 5 years old. Garage kept and only 18,000 miles when the trip started, I was concerned with dry rot, but the dealer said they looked like new. I'll replace them before wearing them out so to speak.
