    I wanted to replace my 5.30-12C’s with new tires. Bought 3 on Amazon.com. Got them home tonight and they are 1 inch thinner than the tires I currently have. A total blunder on Amazons part in my opinion. They are labeled 5.30-12. But don’t measure up. My current tires are 4” depth vs the 3” from Amazon. Hopefully will save someone else the headaches, they were Carlisle. Anyone else with this experience. Now I’m not trusting the 5.30-12 sizing.

    Take it and compare it to one at Northern Tool or Tractor Supply.

    are you trying to compare mounted/inflated tire to one that is not mounted/inflated?

    I agree with Rabird once mounted the shape and size will change. Also the Carlisle tread will differ from the Load Star. Here is what the Load Star looks like mounted on my utility trailer. In the end I’d not worry about the tread surface area as much as the load range rating that you have and a C should suffice on most Pop-Ups.

    Yes. The tread contact on the road wouldn’t change in my opinion. 3” of tread width is going to stay 3” even when inflated. .?

    just checked my Treadstar bias ply tires - 5.3-12 etc, they are 4" wide across the tread face (it would not change much if deflated)

    Tire shop says the same as everyone here. Inflate it and it will be closer. Picking them up in a couple hours. Will see.
    Thank you everyone

    Thank you Anthony for checking, I’m going to guess these work out to 3” still once inflated

    Do you recall how much the load star tires were?

    The Treadstars were/are on my 2003 Aliner Scout Low Profile when we bought it 2nd hand (so I don't have a price for you) , the two road tires were manufactured in 2015 trailer, the spare is a 2018 carcass. The Treadstars did fine on my recent 2,000+ mile trip, even though not inflated to the max sidewall pressure. For off-road use, I left the air pressure as-s and slowed waaay down.

    I would have hoped that there were profile standards for these trailer tires, like passenger tires. Maybe not.

    I paid about $40USD each for them several years ago from a local tire store in Canada. Canadian Tire had the Carlisles for about $10 more otherwise I probably would have wound with them. I see in the US, Northern Tool has them for $36. I’m now in North Carolina and when we replaced our Pop-Up tires last year we went to radials. They were not more money and run really cool with little hub heat. One thing is that they are a bit shorter on the sidewall. Here is the link to that post:

    Honestly, those look much better compared to my tires after last year's camping fun. bad tire.jpg

    Note to all: Check your bearings for proper grease before you go on a long trip.

    I got rim and tires from Northern Tools. But I would look online at their site... I ended up getting them for 60 a piece because they were on sale online, but not in store. I just showed them the online sale price and they gave them to me for that price... Which to me was a great deal

    I went to the radials when it came time to replace. Had a friends nephew mount and balance them. What a difference!!! Plus the radials are weight rated much higher. Ride is so much better.

    As I remember, trailer tires, along with agricultural and industrial tires are not regulated for size. Automotive and truck tires are. There can be big differences in actual sizes across brands and even models with in a brand. If your changing in sets(which is preferred) then it really doesn't matter. Mixed matches can be troublesome with dragging and wondering/sway.
