    Default Trailer tires versus car tires

    Ok, guys the new boat is running great etc, but the trailer tires are less than desirable, sidewall cracks etc from age (original tires). Been looking into tires and some say you have to use a trailer tire, others say passenger tire is fine, but subtract 10% load for passenger tires etc. In everyone's experience can I go with regular tires, or do I need to stay with Trailer tires?

    I have always used passenger car tires with no problem, but then I have a tandem trailer with a v-Drive flatbottm.
    In other words there is not much weight on the tires.
    One of the advantages of trailer tires is the sidewall. They tend to be much stiffer than most passenger tires and
    results in less swaying when being pulled.
    I would say that overall trailer weight should be considered.

    My trailer and boat weigh in at 2900 according to the paperwork form the dealer in 1979. This is dry of course. Then 400 more pounds in fuel etc, and maybe 500 in gear, puts me at 3800 lbs. Its a tandem trailer as well. Just trying to decide which route to go, hear bad things about trailer tires.

    I had passenger tires on my tandem trailer and switched to true trailer tires and they were a huge improvement! Don't remember the ply or rating off hand but they are pretty stout!

    I have an eliminator 207 and i use passenger car tires.I got 8-9 years out of them.Last summer i had one blow out going to the river and when i got home another had a nice bubble.I paid 120 for all 4 when i bought them at the time trailer rated tires were 90 a piece.

    I never had trailer tires of any kind go for more than 4-5 years.My toyhauler they begin to break apart around 4-5 years

    I just replaced my boat trailer tires last year so opefully another 8-9 years out of them again.

    Suggest always give thought to true trailer tires whenever feasible

    I had them on my tandem axle trailer and they were just too stiff. I don't tow fast but man hitting the bumps made the trailer bounce. I tried different psi but didn't want to go too low.

    considering that most of your passenger today cars weigh more than your boat/trailer combined passenger tires will do more than the trick and cost less generally. plus if and when the time comes when you blow a trailer tire out 9 times out of 10 the tire shops only going to carry a passenger car tire to replace it with anyways. comes down to personal preference though. I've run both and currently on passenger tires and like the ride quality much better than what I recently took off

    Default Tires

    Been running these on my 21' trailer since 2009, really like them. Tows better, good tires wear. I've had zero problems. Just actually replaced the whole set because of time, not tread wear. Cheaper to replace tires when they are ready then do it when it takes out a fender....

    The only downside to passenger tires is that they will flat spot if the boat sits a lot. If the boat is going to sit for any period of time I take the weight off of them.

    I've had good luck with Tow Master trailer tires from Big-O tires. Keep them inflated to max pressure and they will last for many miles. I've had mine close to 10 years and probably 30,000 miles and they still look almost new.

    Haven t decided yet, but im leaning towards Carlisle radial trailer tires. Suppose to ride like a car tire, and have the benefits of a trailer tire. The are only a tad more than car tires, not a huge difference cost wise. Anyone have experience with them?

    I won't run passenger tires on a trailer. When I bought the CV23 the PO told me the trailer had 1yr old trailer tires on it. After driving ~7hrs to pick it up in Udall, Ks, I find passenger tires on it. Two of them blew out on my trek home. They must have been higher quality tires though - felt the usual rumble and jerk when each went, but the trailer seemed to still tow fine. My son was driving (first time towing), and I freaked out when I felt the rumble and jerk. The trailer didn't waver or list to one side, and we were about 15mi outside of Limon, so we continued on. Thought it must have been rough road etc since I-70 was having alot of work done to it in western Kansas. The second went about 5mi outside of Limon. Got to Limon (about 50mi from home) and stopped to check. Both tires on one side were riding on basically just the steel bands, but still holding air.
    Had to leave the boat/trailer in a truck stop parking lot overnight, source two new trailer tires Sat morning in Colo Spgs, had the other two replaced when we got back to Colo Spgs.
    If I had known the tires were passenger tires, prob would have been a deal breaker for me. Didn't really want to blow ~$475 on new trailer tires right away. I could have saved a bunch of coin by using passenger tires, but some things are just worth doing right.
    If you tow 5-10mi to/from the lake, no biggie, but I have to tow 85mi each way, so spending the extra coin makes sense.

    I've run passenger tires on my jet boat trailers with no troubles. At 1 time I had a 23' Rinker with a cuddy cabin(heavy boat) and always ran a good trailer tire on it. I think it just depends how the weight and how far you have to tow.
