Any advise on trailer tires? I have a 17ft. I/O open bow 3.0 Merc, aprox 2000-2500lbs with trailer. Live in Phoenix where temps can climb well over 110 in the summer, if that matters. Thx in advance,<br /> AZ Mike :cool:

Re: Trailer tires

AZ Mike, I had a set of Carlise Tires on mine. they only lasted about 2 seasons before they started to crack. I am sure the heat has something to do with that! I am glad it's staying a bit cooler right now! Anyway, for reference, I tow about 3500#. Went with goodyear this time, so far i like them better. The Carlise seem to buldge much more and the goodyears seem to be keeping a better shape. <br /><br /> I know this has been discussed at length so if you do a search for tire brands i am sure you will get alot of hits...<br /><br />wes

Re: Trailer tires

New thing around here is filling the tires with nitrogen.<br /><br />Do a search for Nitrogen filled tires on google. They heat up less, disperse heat better too and maintain better pressure.<br /><br />This might be good for tailer tires too.<br /><br />Bob

Re: Trailer tires

Make sure the tires you buy are not auto tires. They should carry the "ST" (special trailer) designation. I also feel Goodyears are the best bet in the long run.

Any brand except Carlisle, any brand! Preferrably GoodYear Marathons.

I second this, Carlise has been a real loser for me. The Marathons are pricy, but the peace of mind I have now is worth it.

Re: Trailer tires

I find all the praise for the Goodyears on this forum very intriguing. And I'll admit my Goodyear Marathons are holding up fine even in advanced old age. But I've been shopping for new trailer tire opinions myself and became convinced to NOT buy the Goodyears because of these incredibly negative opinions that I found...<br /> http://www.epinions.com/Goodyear_Marathon_Radial_Trailer_Utility_Tire/display_~reviews <br /><br />Then I searched for opinions on the Carlisle tires in other forums and found mostly praise. So I'm as confused as ever...I think it's probably a crapshoot.

Re: Trailer tires

It is hard to believe all those negative comments about the goodyear marathon. It is very irresponsible of goodyear to manufacture such weak tires. Tires should be as good and lasting as vehicle tires. And these tires don;t come any cheaper than vehicle tires. <br /><br />This is my second season for the Loadrite tires. I hope these don't blow up on me. <br /><br />And how come no manufacturer has resolved the bearing maintenance problem? On this century, nothing much has been done to improve trailer components. Everybody has an issue about trailer bearings, annual greasing, someone invents the oil bath but the spindle and hub manufacturers don't incorporate such (good??) technology.

Re: Trailer tires

Craze1cars, what were you smoking when you found good comments about Carlisle tires? Speaking from experience, 5 out of 5 Carlisles less than 2 years old and less than 80% loaded, Carlisle replaced them no ? asked and I'll be dam*ed if they weren't junk too. I was spending more time alongside the road with a jack under the trailer than I was in the water. Carlisles? Suit yourself!!!

Re: Trailer tires

The tires referenced by the travel trailer posters were P225's which are passenger car tires. Trailer tires are designated "ST". No wonder they had problems. Soft sidewalls are a problem on a single axle trailer. Put them on a tandem axle trailer and the scrubbing they get from sharp turns can't help but ruin them.

Re: Trailer tires

Wow, I'm really confused now. I was leaning towards the marithons but after reading the opinions on the link from craze1cars I'm not so sure anymore. The boat came with goodyear conqwest car tires and they seem to work fine, I just noticed they are a little dry rotted from the sun. My boat is a beat up 91 fixer upper with a re built motor. I would like to get some good tires on the trailer but the goodyears are a little pricey for me.

Re: Trailer tires

Why is it so important to use ST tires? I understand about the stiffer sidewalls, but it's not like I'm towing a 5000lb boat with brakes. If regular tires can be used on a car thats heavier and cornering more aggressively and breaking hard, then why are they not recomended for trailer use? <br /><br /> The thing that I am worried about the most is that I have a single axle trailer and if one tire blows on the freeway at high speed. I can see the boat jacknifing or flipping over and causing a huge accident and me and what's left of my boat on the 6:00 news!

Loadstar tires have worked well for me also.

Read this article for an explanation:<br /><br /> http://www.championtrailers.com/tire_art.html <br /><br />If auto tires were suitable for trailers there would be no reason to manufacture and sell trailer (ST) tires.

Re: Trailer tires

Bear in mind I was researching and comparing RADIAL trailer tires. I'm a little surprised nobody here has mentioned any suggestions regarding the choice we have between radial and bias ply trailer tires.<br /><br />As for what was I smoking? Only the good stuff, dude. I reports what I sees. But I don't know much about this subject either so I'm not giving advice here...that's why I was researching info from other sources, just sharing what I found.

Whatever tires you get, keep them inflated to the maximum pressure stamped on the sidewall. Underinflation causes heating.

Re: Trailer tires

For everyone's entertainment and to further deepen the fog, here's another long, drawn out battle I found on this topic with a lot of Carlisle bashers:<br /> http://outdoorsbest.zeroforum.com/zerothread?cmd=print&id=351913 <br /><br />And here's another with some more Goodyear horror stories.<br /> http://www.rv.net/forums/index.cfm/fuseaction/thread/tid/14129448/gotomsg/14137228.cfm <br /><br />There's a consistent theme here, and none too surprising: Everyone who has blown some Carlisles is a Goodyear fan. Everyone who has blown some Goodyears is a Carlisle fan. And for all we know, we're all comparing apples and oranges since some are running ST tires, some radials, some bias plys, and some people probably aren't doing proper maintenance and are complaining about a failure that they themselves caused by overloading, improper application, speeding, wrong inflation, UV Rot, etc. etc...<br /><br />Maybe it's time to check into Coopers or Titans or Firestones? They make trailer tires, too...but don't seem to be talked about very often, so maybe no news is good news? But the more I look, the more I honestly feel that there is no answer to this "which brand is better" question, we all gotta fly by the seat of our pants...it's probably much more important to get a proper load rating, keep tire pressure correct, protect them from the sun, don't let them flat-spot in the off seasons, keep the speeds down, and check them often for wear/cracks/bulges/problems.<br /><br />What gets me more than anything else is the number of complete morons (yes, morons...and if you fit this category you are indeed a complete moron and I won't apologize for saying so) who actually tow trailers without carrying a functional spare tire and the necessary tools & jacks to change it. The last 3 used trailers I purchased from private parties had no spare...when I inquired if one was included in the sale I expected to get a normal reasonable answer like "I'm keeping it for my new trailer." But no, I always got "it never had one...never thought about it." Morons. Ok, I'm done now. :D

Re: Trailer tires

Craze -- I'm with you on the "no spare" issue. Chances are these same "people" (I'm just a little kinder than you) probably don't have one for their car either and see no reason to start looking for tires until the air is showing!
