Trailer, Light Truck Or Passenger Tires?

    I purchased our 550 #318 used, and it had several trips to the coast causing a lot of rust on the stock rims. I'm swapping them out for a 15" Aluminum wheel within the size parameters Cary recommended. My trailer currently travels on Passenger tires, which the guy at Discount Tire noted would normally not be his choice but the light weight of the trailer lessens his concerns.

    Since I bought used, I don't know if the original tires were ST (Trailer) tires or something else. Would you recommend ST (Trailer), LT (Light Truck) or P (Passenger) tires?

    Thank you CI Community!

    The original tires are STs. We just replaced our original tires. The two tires cost us less than $150 installed, including disposal of the old tires. Trailer tires will be cheaper than passenger tires, so it would depend on how much research you would want to do to find a comparable passenger or light truck tire.

    It depends on what tire option you originally had. The street sized tires are LTs and the SUV sized tires are LTs. For single axle trailer applications it really does not matter much what type of tires they are however. Unless you are in some Canadian Provinces where they care for some reason.

    For your application of wanting to run an oversized 15" rim you will need a very low profile tire which will mean a passenger car tire will probably be your only option.

    Just returned from an extended trip and need new tires. My 560 ST tires lasted around 8,000 miles and
    I'm told that's not bad. I'd like to do better and Cary has suggested LT tires as a possible alternative. Most
    treads I've read say 65mph is the max for ST tires. I drive closer to 70 and my wife "wants to get there" so
    she'll push 75+. We pull with a 2015 Toyota Highlander 6cyl AWD for what that's worth and it seems hitting
    70+ dramatically affects the mpg. Getting around to my question, anyone having better luck with LT radials
    vs. the ST D rated tires with regards to tire longevity and decent mileage?

    I ended up going with a trailer tire that was rated for 75 or 80 mph, forget which...that's important for me as I have 70-85mph speed limits all around me. Discount Tire spent a lot of time with me because they loved the trailer. They felt LT or Trailer tire were the right options. The size I wanted put me in the trailer tire.

    Reviving an old thread simply to share another opinion/option . . . after a lot of research, I ended up getting passenger radials for our 560 Ultra (SUV). I went with Cooper Trendsetter SE All-Season Radial Tire - 205/75R14 95S.
    Given the relatively low weight of the CI's, I wanted more 'bounce' than a trailer tire provided. I also wanted the higher speed rating. Zero miles actually driven, but they look good in the garage :)

    I've got about 4,000 miles on my trailer tires, and so far so good. I think a CI is going to bounce regardless of the tire just due to the limited weight. I'm still getting plenty of bounce! My initial concern was my decision to move to a 15" wheel as I couldn't find anything in black that I liked in 14". It narrows the gap between the tire and the fender. However after a 3,600 mile trip in just about every possible condition of road, that's no longer a worry. Not sure we've settled the debate about which tire is best for a Camp Inn, but does seem like all options are on the table.
