Hello all...I need to replace my tires and wanted to know which ones are the "better" ones to get...Carlisle or Greenball. Has anyone had any good or bad issues with the two..

Thank You

Also..My trailer calls for 7:00x15 6 ply tires. Is this the same as 700:x14.5 tires?

Aluminati,

NO, the 15 or 14.5 is the diameter of the wheel and the tires are not interchangable. If I remember correctly from a recent episode of TheVAP, the 14.5 was used in only 1958. That size is common, however, on mobile homes.

I had Carlisles on a previous (SOB) trailer and had constant problems with them.

Friends have had good experience with Greenball.

A friend of mine has an SOB that weighs approx 8000 lbs loaded out. He pulled it (2004 box trailer) to Wyoming this summer and had three tire failures. These were apparently belt seperations and tread delaminations.

He pulls with a Ford V-10 and tries to run 65-70mph.

The tires were original equipment Carlisle and he lost 3 out of 4.

I am only relating what he told me. There could have been trash on the road that penetrated the carcass, etc. Tires were not checked by a knowledgeable eye so who knows. For what it is worth.

Never really heard of green ball?

Carlisle tires are limited to 60MPH & must be inflated to max pressure listed on the sidewall.

Foiled Again · 10-22-2007, 12:32 PM

NO trailer tire is rated above 65 mph. High speed invites all sorts of other problems - like the trailer pushing you if you brake, or a rollover caused by a flat or a tire going off the pavement.

If it's as purrdy as an Airstream... SLOW down so that the peons can SEE it!

Great!!!...no wonder they were at such a good price...$ for (4) of them mounded and balanced. I guess my mom was correct...Just because you pour syrup on poo dont make em pancakes!!

I have Carlisle 7x15's on my trailer, were there when I bought it two years ago. I had to replace one that picked up a nail too close to the sidewall to be patched. I had to replace it with a tow master. 2 years, 20 trips, 5000 miles and 1 nail. Not everyone has had bad experiances....

HowieE · 10-22-2007, 03:07 PM

What ever you consider buying check the country of manufacture. Greenball shipped the molds to China last spring.

What a lot are now doing is installing LT truck tires that have a rated speed above 65 mph.

I just replaced my wheels with 16 in. and now use Michelin LTs

Beginner · 10-25-2007, 05:45 PM

BF Goodrich is owned by outright by Michelin.
A close friend of mine has an uncle that is a corporate officer of Michelin located in South Carolina.
The uncle assures my friend that the BF Goodrich is just an inexpensive Michelin, not a cheap Michelin.
Also, as I have stated before the Commercial T/A Load Range D in LT225/75R16 is the same outside diameter as the Original Michelin XCA 7.0015 that came on my 1984 31 foot Excella and the same max width as the Marathon.

I also have Carlisle's, two years on them and several thousand miles no issues what so ever. Mine are load D's (80 psi) and have been fabulous thus far. It is not uncommon for me to tow in excess of 65 mph, typically around 70 or slightly over. They are mounted to the aluminum mag's 7" x 15" and balanced individually because I have had the brake drums precision balanced to 1/4oz./in. Seems to me the vast majority of tire failures that I have read about and even witnessed have been Marathons.

Dave,

Are you sure about that max cold pressure. Typically, LR 'D' tires get 65psi and LR 'E' tires like the LT 225/75-16 that I run on my Sprinter and now on my 19CCD go to 80 PSI max cold.

Better check the sidewalls of your tires again....please!

Aluminati · 10-26-2007, 07:27 AM

Well, I purchased the Carlisle tires...have't put them on yet...it will be a week or so before I can do it. I purchased 4 (D) rated tires 8 ply for $272 Mounted and balanced. Paid for them on Monday...the guy said he only had three...after I paid for them

. So he said he would order another one from another store and it will be in on Thrusday. I went into the store yesterday and he did not know if they came in...

. So he said let me go check....now I am waiting...and he comes back with 4 tires.

but they were not the ones I orderd...He gave me the 10 ply E rated ST225/75R15 with a capacity of 2830lbs each.

I am not looking a gift horse in the mouth but will these tires be good for my 4K lb overlander and is this overkill?

Safari-Rick · 10-26-2007, 10:43 AM

Does anyone have any info (good/bad) on Loadstar trailer tires?

Trailer Parts Superstore - ST225/75R-15" RADIAL Tire, L.R. 'D'

LOADSTAR's KR03 'KARRIER' Series Trailer Tire.
Radial trailer tires are constructed for a softer, more quiet ride than bias ply tires. 'ST' series trailer tires provide better durability and bruise resistance under heavy loads than 'P' series passanger car tires.

Beginner · 10-26-2007, 10:51 AM

What do you know about this brand of tire?
That tire is made by Kenda. Here is there web site:
Kendausa
Here is the answer I got when I was searching for a tire better than the Marathon. Replys like this one drove me to go to 16 inch wheels and LT tires.

Hi ,

The trailer tires all designed for speed rating at 65 mph. Lots of people towing at much higher speed is not what tire manufacturer recommended.

The consideration of upgrading to 16" tire seems related to loading capacity issue instead of speed rating issue. As far as I know, there's no 16" tire has same loading capacity with same OD as 15" tire. Even if it has that most likely will be a LT tire not the trailer tire. You will having the risk of using LT tire or pay more for people make the reinforced LT tire to be fit for trailer application.

We will have a 10P ST225/75R15 tire at 2830 lbs capacity available soon if that's what you need.

Hope this help!

I assume that you have a 30FT slide (heavier).
You may need the Load Range E tire, however, The long pole in this is speed rating. You need better rubber compounds to withstand the higher heat or inflate the tires til there rock hard(Goodyears suggestion to overinflate by 10 psi to run faster than 65) but that will just beat the devil out of your trailer.

Safari-Rick · 10-26-2007, 01:20 PM

Whoa !, It makes you think if there is such a thing as a quality tire for travel trailers!.

Beginner, thank you for the info.

This reply and others like it from other tire manufacturers of ST tires is why I stopped raging on just Marathons. Its a tire type/class problem. Again, would I put ST tires on my boat trailer that goes across town at 45 miles an hour or less on a trip that lasts 45 minutes or less? Yes I would.

That being said, Cooper makes a Custom Trailer Plus, ST22575R15
Cooper Tires - Tire Specifications
with a speed rating of S (112 MPH).
Tire Tech - Speed Rating, Load Index & Service Descriptions

These Cooper Sustom Trailer Plus Tires are hard to get a hold of, but if they perform as advertised, theoritically, you will not have any trouble with them.
BF Goodrich Commercial T/As in the LT22575R16 Load Range D are a lot more available on the road (you still hit stuff on the road you know).

Yup, The side walls say 80PSI max. cold. I use a digital tire pressure gauge and I will set them all at 79.5 psi. the guage resolution is +/- .5psi, so that way I know they are all within 1 psi of each other.
