Trailer Tires?
I need to replace the tires on my trailer. Question is do I need to get specific with them or just get some ordinary replacements. I plan to go with a decent brand but I've been told by a lot of people to just put regular ole tires on it and let it rip. My wheels are 15inch and I'd like something a bit wider too.

formula31 02-20-2003 05:36 PM

Get the Goodyear Marathons from There are plenty of good reasons not to use regular tires.

Playn 02-20-2003 05:55 PM

get the proper load rating

boot 02-20-2003 06:29 PM

I use good year marathons too on the trailers I sell . most Car tires will dry rot on trailers. What ever brand , make sure they are "trailer" tires . Usualy marked "ST" for " special trailer " tire . ANd get the right load range "C, D, or E" depending on your boat weight .

Robbie Racer 02-20-2003 06:51 PM

My Extreme trailer came with 14" rims with "C" rated tires that aren't the right load range for my boat. I blew 5 trailer tires last year and don't want to go through that again this summer. Does anyone know of a D rated tire that will fit on a 14" rim? I'm even having trouble finding a D rated 15" tire with a 27" diameter so that I can fit it under my fenders.

sauron 02-20-2003 06:56 PM

Don't help pay for the blimp, get Michelins. I pull all over the country and have never had a problem with them. Blown out many Goodyears and other brands.

liquid asset 02-20-2003 07:28 PM

Marathons suck you can have those peices of chit. I've blown several but I do tow at 80 like a dumbazz I use Carlisles from discount tire never had trouble with these. I had so much trouble with my goodyears, bubles on the sides, they gave me new carlisles. they are about 59 bucks a peice. Always use special Trailer tires no matter what anyone tells you

H2Xmark 02-20-2003 08:18 PM

what matters most is get trailer tires because they have more plys and will not flat spot as easy as car tires, and get the proper load range, other than that the brand is your choice, you will hear good or bad about all tires, put it this way a chunk of metal in the road does not care what brand tire you have

Robbie Racer 02-20-2003 09:04 PM

Thanks guys for the info. Mitchell the diameter of the 225/75R15 D rated Marathon is 28.3". I think I will need a diameter of 27" or less to keep from replacing the trailer fenders.

I currently have 14" Carlisles C rated but they are blowing because they aren't rated for the weight of the boat.

Robbie Racer 02-20-2003 11:11 PM

Shane, thanks for the info. You have had much better luck than I did with Carlisle. I sent back one tire and despite several follow up calls, they blew me off. I should have gone through Extreme first like you did. I'm sure they carry a lot more weight than I do. Yeah, let me know the size and maximum lbs. on the new tires and gave me the guys number. Thanks, R/R

97BossHammer 02-21-2003 08:30 AM

OK, I'm looking at it a little different now....I'll get what you guys suggested. I was thinking goodyear's but now I'm mixed about it. Whatever I do get I'll make sure to get the right load ratings and stuff. Basically the tires that are on it now are dry rotting. I bought this boat from Canada and it was pulled down looked ok but have just gone downhill since.

obnoxus 02-21-2003 10:09 AM

Now this makes no sence,,,, EVERYONE I know in Chicago that had Carlisles had them blow out on them,, my friend even had BOTH fiberglass fenders ripped off his trailer,,, one on the way to LOTO and one on the way back,, OUCH .

We all went to Goodyear Marathons and havent had a problem since,, they are only $60 through tire rack,,, not bad in my book.

jafo 02-21-2003 10:35 AM

Zero problems EVER with Carlisles here- on everything from car haulers to utility trailers, snowmobile trailers, and two different boat trailers.
The folks I know of that have had problems with them were:

#1) All on triple axle trailers with too light a load range tire for the weight carried on the trailer.
#2) Not inflated to max PSI as labeled on the tire.

IMHO, they make a very good and affordable radial ST if used correctly.;) :)

obnoxus 02-21-2003 10:48 AM

ours are all 26-28' on tandems,,, they were stock tires on the Eagle trailer.

Quality Time 02-21-2003 11:17 AM

Avoid Carlisles! I have gone through two sets in less than two years. One blew and tagged my trailer fender. I was told they had a bad run on tires and a lot of boaters and travel trailer owners had major problems. Spoke with one guy who was on his way to Lake Powell for a week long vacation when his Carlisle tire blew and knocked a hole in the side of his little pickle fork. So much for his vacation.

97BossHammer 02-21-2003 02:11 PM

good grief i'm confused ;) haha

Robbie Racer 02-21-2003 02:53 PM

Has anyone heard of Woosung tires? One tire dealer recommended them to me as the only 14" tire that had a higher max load rating at 2,095 lbs. that is 27" or less in diameter (to fit in my fender wells). He said that they are made in Korea and he puts a lot of them on trailers for heavier boats. He says they are a 8 ply tire. I have never heard of them.

birdog 02-21-2003 06:29 PM

I put Carlisles on every trailer i own. Never had a problem ?!
Always inflate to Max pressure on sidewall.
20 + years running them on lots of trailers...But...Who knows???

Dock Holiday 02-21-2003 08:35 PM

I am a Goodyear guy all around. Have had good luck on autos, trucks and trailers.

The last two Myco's I have had came with Goodyear's. Total now of around 5000 miles without any trouble. I probably just messed my record up telling you this. We will pulling the boat back from Florida in a couple of weeks.

The key with any tire for anything is to have the right tire. It must be made for the application, and capacity needed. Secondly and as important is tire pressure.

I check all tires before any trip to make sure they are 100 percent on tire pressure and look for any noticable problems before I hit the road. One thing I see a lot is trailers that are not level. If you have to much tongue weight the front tires will be carrying the load. You must have the trailer level so the load is distributed equally.

I have a laser temperature reader that you can just point at anything and get an instant reading on. This is a must when towing something like the 36 for long distances. The first thing I do when we stop somewhere for a break it walk around the truck and trailer and check all the temperatures. In low sunlight all will be about the same. If the sun is bright, the tires on the shaded side will read a little less. If they are all within about fives degrees maximum of each other you are OK. If you have a tire going bad, you will instantly know it. They can and will read as mush as 20 to 30 degrees more. Take it off right then and replace it before it blows. Much easier and much safer.

Year before last we were towing to Miami with a couple of other boats. It was 30 degrees here in North Carolina when we left. We stopped at a truck stop on the South Carolina/Georgia line around 3 o'clock in the morning. I started checking all my tires and they came in around 55 degrees. A buddy asked be to check his and they were all about the same except for the center trailer tire on the port side. It was 100 degrees. He checked the tire pressure and it was way low. Found the hole, plugged it, aired it back up and was back on the road in about twenty minutes. We did not get 15 miles before it blew and was all over my windshield. Never again, if they are hot, they go.

This little device works GREAT, I would recommend it to anyone.

Sorry to be longwinded, but the right tires, set up right seem to work well for me.

Robbie Racer 02-21-2003 08:46 PM

Thanks Shane.

Dock, that's a great idea about the laser temperature reader. I have "felt" the tires with my hand to see if one were hotter than another before but the temperature reader is a much better idea. Thanks, R/R

RLW 02-21-2003 11:54 PM

I bought my last set of "Trailer" tires from Pep Boys. They were Generals and the price was better than the others mentioned. Everyone else wanted $75 to $85 a piece and the Generals were $50. They were true trailer tires, ST rated with the proper load rating.
Correct air pressue is important to longevity.

US1 Fountain 02-22-2003 12:02 AM

Marathons here with no problem. I agree with Mr O. (is that you Mr. Obvious??) :)

h2owarrior 02-22-2003 12:22 AM

Load rating and pressure. If they are both correct, there should be no problems other that typical manuf. defects (if it's man made it will break).

I had a 290 PQ on a triple axle axle trailer with 14 inch "C" rated tires that were on the edge for load rating. Kept the tires fully inflated and blew three in 35,000 miles (marathons). We were never left stranded. Always had a spare that was properly inflated.

New MYCO has 16 inch Goodyear's. Have about 5000 miles on them and are doing fine so far.

obnoxus 02-22-2003 12:53 AM

When I blew my Carlisle I switched all four cuz I didnt want to chance anything,,, the guy said the looked like they melted,, the cap delaminated,,, and the other 3 were not far behind,,, I am very anal about trailer maintenance,,,, but I also tow faster then I should,,, so I thought it was self inflicted until I started hearing about the others with problems,,,, I still tow faster then I should,,, I still take great care of my trailer,,, and my Goodyears are still in one piece !!!!!!!!!!!

Dave M 02-22-2003 07:51 AM

I need to replace my tires this spring. I keep hearing about load ratings. Is it correct to say that with a tandem trailer the load rating should be 1/4 of the weight of my boat? Or the weight of the boat and trailer combined? My boat weighs about 3500 lbs, I have a galvanized tandem trailer, so I estimated my rig weighs about 5000 lbs. What rating should I be looking for?

One more thing, the tires I have now call for a max of 35 PSI. I bought a spare and it calls for 50 PSI. This tire looks a lot better than the ones on the trailer. Are the higher PSI tires better?

jafo 02-22-2003 10:26 AM

obnoxus- It may be possible that you had Carlisles from the 'bad run' of the eventually recalled Carlisles? I do agree, GoodYear are great tires. I just haven't had the problems with Carlisle either.

Dave M- weight of boat fully loaded with fuel and gear, plus trailer, and add 10%. Then divide by four. This gives you a decent safety margin. Run at full inflation as listed on the tire. Make sure the trailer is properly balanced, with proper tonque weight. I've seen people compromise because of their fenders. Not a good decision- get the biggest load range in there that will fit. NO REGRETS!

Just as an example on how critical tire pressure can be-
On a typical corporate jet, a difference of as little as 10% pressure between two tires on the same main landing gear can cause the anti-skid system to either be inoperative or send false skid signals to the computer. Not good at jet landing speeds!
We check tire pressure (nitrogen only in aircraft) prior to every flight.

Great Info Guy's!!!

If the225 is to big,, Ialso have 205's and I think 215's but I'm not Positve!! The Marathon ST205/75R15 is a C rating {6 ply}
$60.00 even I'll try to remember, to bring home the G.Y. Book!!
I love the Marathons, myself!!! I have them on my Trl. That Tire is by far ,our best selling Trl. Tire!!


mama tryed 02-25-2003 06:11 AM

The 205/75R15 has an Overall Dia. of 27.1 The Width is 8.0 The Load Capacity is 1820lbs @ 50lbs

Have a Great Day!!!!!!!

Dave M 02-25-2003 07:25 AM

My trailer has a GVWR of 5400, and a GAWR of 2700. I currently have load range B tires on there, ST205/75D14.

Would I benefit by putting a larger tire such as the 215's or a load range C tire?

mama tryed 02-25-2003 07:47 AM

Hey Dave ,, The Marathon 205/75R14 B, has a [email protected]
The C Rating or 6ply ,, would put you at 1760lbs Capacity..
The 215/75R14 has1870lbs Cap. and is only .6 more in Diameter and .5 more in Width.

Gotta Go,, Hope this Helps,,, Oh yea, we have these in Stock !!!!!!
