i have a dual axle trailer is it safe to use car tires on it if the max load of the tire is over the weight of the boat
-
For the weight we carry, you won't have any problems with regular automotive tires.
But, with that being said, I do run the Maxxis trailer tires on mine. ;)

awesome looks like I'm getting new tires on Tuesday
-
ya if i buy a boat and the trialer has trailer tires on it, i rip those pieces of crap off and get standard car tires. I pull my boat all over the state and the only problems i have ever had are with trailer tires. once i put the car tires on, my problems go away
-
The ride is a lot better as well. The trailer won't bounce as much. i have been running.g car tires since I got the Nordic
-
ya when i got my new boat i pulled the tires off and put car tires on

I disagree, and am with Crewcheif. I only use trailer tires (And have never had a failure, like anything else, they need to be maintained, checked, armor-all'd, etc), and I trailer an hour at minimum, normally 3+ hours to get to water at freeway speeds (75MPH here in Arizona).
Reason being, car tires are designed to give better ride and control in many varying conditions, even at high speed such as the forces of accelerating and stopping, turning, etc. Trailer tires do not need most of this. What they need, and do, is much stronger sidewalls (You're gonna curb 'em far more often, and stress/tear up the sidewalls on tandems or triples particularly just cornering), and their "ply" construction and ratings are real because they are bias ply tires, and harder compounds to absorb more heat, and induce less wear and tear since they are usually quite a bit smaller in diameter than you're car/truck tires. THUS, they spin much faster and much more often per mile.
Trailer tires are typically 6 or 8 bias ply in light trailers. Radial tires are normally 2 ply plus a steel belt (not counted as an actual ply), and the "ply" rating on them is a "strength equivalent" abbacus computation to compare them directly to bias ply tires because the DOT requires it. Whether that number is accurate or not is not the point. If you doubt this, next time you replace your $600 each Heavy Duty 12 ply rated off road truck tires, cut one open with a sawzall. I think you'll be surprised. Load ratings are another thing that are completely different and you cannot directly compared between trailer tires and passenger car/light truck tires.
The biggest complaint, and legit, on trailer tires when they fail is because they just "flew apart". That's usually not the case. These tires RARELY wear out, on the tread side of things and besides looking at that, air pressure, and weather checking, noone pays any attention to them. There are date codes on these things (there's a website to tell you where and how to check that), and it's very common to find tires 5-10 years out of useable date. I have project boats here that I KNOW the tires on the trailers are original from as far back as 1976, still hold air, plenty of tread left, look decent, and I wouldn't tow them down the street to the Circle K. The rubber compounds degrade over time, through heat, UV light, alien intervention, whatever.
18 wheeled tractor trailers or any heavy truck still use bias ply, know why now?

im sure all the evidence says use a trailer tire. But Everytime i have had trialer tires they wear wrong or i sling the tread off of it and it fucks up my trailer fenders. My old jet boat had a set of regular tires on them that had to be 10 years old. they never once failed.
I bought that new boat of mine and the trailer had a brand new set of trailer tires. one blew the 2nd weekend i took it out. So i put the spare on there. A week later the other side blew and messed up my other fender well. I said screw this. Went and got some regular tires. it has been 3 years now and not one of them has even lost air pressure yet.
I am sticking with car tires. plus they are way cheaper.

Bias ply in a trailer tire is getting harder to come by. I just put 6 ply trailer use only radials on mine cause I found a bubble in the old tires.
I think the biggest killer of trailer tires is sitting, if I know mines gonna sit for a while, I'll throw some stands under the axles and let some air out...
I paid 380 for five tires mounted and balanced. They ain't michellin or bridgestones but they will always be fresh every few years.

22.5 and 24.5 have been radial for 30+ years now,
BIAS ply tires are dead should be banned on anything larger than a hand truck or wheelbarrow.
I run 25-30,000 miles per YEAR on (radial)LT tires on a triple axle trailer, 24,000 gvw, thats TWO sets of bias ply tires in a year.
Tirerack wants to sell tires
Radials are best, Loprofile handle really well too.

Mash on it

cant rock the low pros i tow the boat with my truck with a 6 in lift and 37s tho if i dint that would be an idea that i would consider
-
so i went to get my tires today they didn't have the cheap tires that i wanted .... so they gave me the next step up at the same price score :thumbup:
-
Yup bias ply for Diesel trucks are definately by the way of the dinosaur. I manage a retread plant and have not seen a bias ply tire in YEARS!!!! They do still use em on the cargo container trailers at the harbor. They are going more and more to radial tho
-
just headed out to castaic yesterday and wasn't 10 miles before one of my car tires on the trailer decided to come apart. So now I need 4 tires as well. All the "tire guys" i ask say i need trailer tires because they are stronger and meant for loads. Now I am confused on what to get after reading this post :banghead:
-
They want to sell you the trailer tires, cause they are way more expensive. If you aren't towing a huge boat go with the passenger tires. DO NOT BUY CHINA CRAP :thumbdown: :thumbdown: :thumbdown: Check the dates of your tires, on one sidewall you will find the letters DOT followed by letters and numbers. The last "4" numbers will tell you how old they are. For example they show 2409, that means they were built in the 24th week of 2009. I could go into what all the other letters and numbers mean but would be useless to you. The date is all that matters.
-
One other thing to think about again is the age. The tires on my trailer looked like brand new. But when I checked the dates on them they were 05's. Bought some new ones, hated to but didn't like how old they were
-
rockin car tires here. some kumho's i think last time i looked. for how much my boat weighs it makes no difference. if i had a 40 foot boat then sure id need a tire with a higher load rating, sidewall, etc.

If your going to use radial car tires, balance them and throw on some shock absorbers, sounds goofy, but radials won't wear square if they are allowed to bounce.
The biggest issue you can have with car radials is if your using a light tow vehicle (like a Tacoma or a passenger car), it can jerk you all over the road.
I use car tires, but have them balanced and use S10 shocks on both axles... And yeah, I over think shit.
Part number 32300 for Monroe shocks, they cost like $20 ;)

pics of your setup? I'd love to see it.

Support Japan instead.

Actually the tires made in Japan are pretty good. A lot ofr their tires are on our A grade truck tire list

I've been thinking about putting a set of BFG Radial T/As on my tandem axle trailer for my 18ft jet. What weight rating do I need? Will 1,433 Ibs max load per tire and S speed rating be good enough to tow my deal??
I'm really tired of these trailer tires that are two seasons old and already cracking and bubbling :mad:
-
I picked up a set of HIRUN tires a few years ago at Just Tires for somewhere in the ball park of 3 bills mounted
There wearing great, no cracks or bubbles and there a radial trailer tire.
The ride is pretty good, i don't notice any more bounce from the previous set of tires

Hmmm, 1433x4...more than 5700 lbs....that oughta do... Ive have radials on my day cruiser, ~4200 lbs
Ive run both bias and radial, and radials are far smoother...go for the BFG's
Bias ply(s) are for tractors.

Thanks guys for the quick response. Now where would you recommend I get my tires? Anyone know anyone in long beach or near long beach that works at a tire shop or anything like that?? 😉

When I found I needed old school 60 series 15's I was stuck going with BFG's. I price shopped online and then went to a little tiny mexican shop. They ordered the tires ( because NOBODY stocks 4 of these things) and beat the big guy prices. No road hazard warranty but I was in and out in about 25 minutes. I think I paid about $106 per tire.
