What tires can/should I buy for a 2720? - Page 2

**pmhellings** · 06-19-2017, 06:55 PM

I upgraded to load Range "D", but stayed with 14" tires to avoid the slightly heavier unstrung weight of the 15" wheel tire combo. I bought the tires and wheels together from e-trailer and had a metal valve stem installed and balanced at my local tire shop.

I've had good luck on my previous camper going this route. You also can't go wrong with the 15" combo as long as you use load Range "D" tires.

Thanks to all who replied, you've given me lots of good info. Now I just need to determine which way to go for availability at my tire shops vs. cost, etc. I'll definitely be going to a Load Range D, whether it's in 14" or 15"

Can anyone provide the bolt pattern for the TMs, or did that change over time? If it's not a constant, how do I measure it on mine? (Mine's in storage, but I could measure it if I knew what to do.) I think I need this for the new rims I'll need, correct?

Also, any advice on brands to look for or to avoid? I've seen Trailer King (which I've never heard of) and Goodyear (which I'm familiar with for car tires). Lots of others too, of course.

Thanks again for all your help!

The bolt pattern is called "5 on 4 1/2". This means that there are 5 bolts, and they are located on a 4 1/2-inch circle. There are a couple ways to measure the size of the circle, but since there is no other size near it, precision isn't necessary.

You would do well to confirm this on your 2720 TM, as at least one exception has popped up.

sorry for resurrecting this old thread but I did purchase a higher load rated tire trailer king 65 psi. was wondering if I can use this tire on my old rims? how can I find the load rating of the rims that I have? There is nothing stamped on the rim for me to tell. it is the old 14" rims. thanks.

What is the size of the Trailer King tires? If they are 14-inch tires, they will fit on the old rims. If they are 15-inch tires, they will not.

As for the rims, their psi rating or load rating is often stamped on the inside of the rim, where you can't see it until you take the tire off the rim. If you remove the tire, and there is no info inside, then I would hesitate to use them at 65 psi. They were supplied for use with the original 14 inch Load Range C tires, which were limited to 50 psi. Were they original to your TM? If so, what year is your TM?

Thanks Bill these new tires are 14". Took the tires off the TM and took pics of the text stamped on the back. The two white rims are new rims and not original. The silver is the original and clearly states 1870 lbs load. Do you know what the white ones are from what the text states on the back?

There is one more stamp on the outside of the rims edge. Hard to make out the numbers but this is the best picture I can take. Could this be a load rating?.

I personally don't think the load rating of the rims matter, in the sense that you do not need a rim with a higher rating if you move to a larger rim. You're not changing the weight of the load -- it's the same trailer. So if the old rims had a weight rating of 1870 lbs, the load rating of the new ones on which the heavier tires are mounted doesn't have to be any higher.

WHAT DOES MATTER, however, is that the new rims are rated to handle higher air pressure. In trailer tires, that typically comes with larger rims, since higher PSI is what gets the higher load rating, but it makes sense to verify.

In my load range E tires, I run at 65 psi cold, which has proven to be a good balance between load support (e.g. no blow outs) and a relatively smooth ride in the camper.

Thanks shrimp burrito... I tend to agree with you on the load rating vs PSI rating. Since I purchased a new 65 psi tire I wanted to make sure that the old rims can handle the PSI rating of the new tires. However can't seem to see any PSI rating anywhere on the rim to know for sure.

Oh and BTW I did a quick search and amazon does sell rims rated at 65 PSI with the same lugs specs and size I need. I just didn't want to pick up new rims unless I absolutely needed them. But I am unsure what these are?

**ShrimpBurrito** · 03-27-2022, 01:21 PM

I suspect that PSI ratings correlate to weight ratings, so my GUESS is that for any wheel rated for 1870 lbs, they will all have a specific pressure rating. If you want more than that, you need more weight capacity.

But that may not be universal, I don't know. See if you can find pressure ratings for a bunch of 1870 lb rated wheels -- if they're all the same, that might be your answer.

But if I were you, I'd get 15" wheels and tires. That resolves the issue, and also gives you a far greater safety margin. Blowouts are expensive (far more than a cost of rims and wheels), always happen at the least convenient time and place, are a major safety hazard, and are sure to spoil your trip.
