    I had planned on replacing our 2010 date code Load-Star 12” 5.30-C bias-ply tires with radials and moving the bias-plys to our utility trailer at the end of the season. But as luck would have it the 12” 4.80-B tires on the utility trailer had dry rotted and lost air after 11 years. So I jumped on a set of 3 Radial Velocity TR088 ST145R12 D/8PR from Giga-Tires.com for $93.00USD and moved the old Pop-Up tires to the 4x6 utility trailer. There was plenty of clearance and they should be fine for a few more years.

    I had the new tires mounted at my local Costco for $14 each which included balancing and Nitrogen. I never balanced trailer tires before but since it was included how could I say no.

    Not being familiar with this brand and the lack of reviews I’ll be rolling the dice when the Pop-Up hits the road next month. Wish me luck and I’ll let you all know how they do.

    Make sure you keep a check on the tire pressures and max speed.

    They do show a M 88 rating and it looks like that is 81MPH-130 km/h. Not sure I ever had our Coleman over 70MPH-110km/h. The old bias-ply tires had 70 PSI in them and could go up to 85 PSI. The new radials are at 60 PSI and can go up to 65 PSI per the tire info. So that is a lower difference. It will be interesting to see how they dissipate heat as the old tires did warm up the hubs.

    Supost to do better with heat at higher speeds and a smoother tracking. Just not as tough sidewalls, and off road. That was my take. I haven't taken mine out to test it, and even if I did I wouldent be able to tell.

    I bought a laser thermometer at HF for $20.00 and keep it in my glove compartment, I check the tires and hub temperature when I stop, only takes a few minutes .

    How are the tires holding up? Mine are good. I didn't get the laser heat gun , but did check the temp by hand on the tires and hubs when we stopped. The chemo tires I got worked well, and the radials were smoother.

    So far so good. We have only put on them about 100miles/160km and I did the hand test several times during the drive and they remained cool. The old bias-ply tires did not take long to warm up so that is a good sign. Also the tires kept the 60PSI spot on, but that may be attributed to the Nitrogen Costco filled them with. The test will come in October when we head to the Sewer Rally which will have about a 260mile/420km round trip with a good amount of Interstate high speed driving.

    ST145R12 is the same as 5.30x12? If so Ill look again. I didnt find much at all in the way of radials (5.30x12).
    What is the story on load rating? 840 x 2 tires = 1680 lbs max load? Is that correct?

    Ok, nada specs show our pup's weight as 1630lbs. I'm assuming that is empty, not GVWR. So range B just makes that, until you put anything inside that is.

    Always go higher on the load of you can. And yes you have it. Weight range x 2. Some off for the toung. But you also dint pack perfectly even. So higher load is better. Depending on the camper and year you have to add in things like propane, ac , etc. Then what you pack.

    Definitely go up to a C if you stick with the bias ply tires. But if you get the radial version it has a 1,200+ weight rating as a D. And it runs cooler and smoother. The size a a tiny bit smaller for height but that it just how it is for the closest size in a 12”.

    I found at recstuff.com the pair of radials mounted on rims for $150 shipped. Thanks for the recommendation!
