Tires for 165 sport, "c" or "d" load??

[Sport165]

Hi,
I recently got a 2004 165 sport, I think it's Max weight is 3500? It needs tires & battery....

I was looking at purchasing two
Carlisle Sport Trail LH Bias Trailer Tire - ST185/80D13 LRC, but unsure if I need the weight bearing load C or D? There's​ a considerable price difference between the two.

Also for a lightweight TT, is it ok to go with 'Bias' vs Radial? It originally came with Duro radials. I'm hoping someone here can offer some insight.

Thanks so much

If the max weight is 3500 lbs, then you need Load D. They support roughly 1700 lbs each (2 tires x 1700 = 3400 lbs, but your tongue jack supports 300-400 lbs so you'll be good). Get Radials in load D. This will make your trailer safe.

Of course, if your max weight is greater or you have this distributed among 4 tires, all the math changes. I'm just using the info you provided.

Standard on your rv are 13 D tires. But they are just they are maxed out if you do the max load.

I would find out if you could upgrade to 14 inch tires and wheels. Would give you a lot more safety range.

Most important is to keep your tires properly inflated with frequent inspections.

Thanks for replying, yes the Duro's were Radials 13 load D.
& Yes, There are only 2 tires on this TT.
*There's a weight distribution hitch, if that makes a difference. With sway bars.

So I will stick with same, however- safety & peace of mind is huge, so I will look into going up to the 14s. Price might be too cost prohibitive though.... I just realized I need to replace the never used spare tire as well.
** Just a thought, but if I went with 14s could I then go with load C?

The spare while never used is 13yrs old... It actually looks good. Could I maybe keep it, if I can't afford the 14s? Or automatic replace bc of age?

[RogerR]

Just about everyone I have read agrees that 5 years is the age max. 13 is just time bomb.

If you buy 14s on a new pair of wheels complete shipped to you the price is not that bad. The new Goodyears are have great reviews. Lots of opinions on brands. I like Kumho radials myself.

You can do a few searches on this site for brand recommendations. Make sure you order balanced wheels, cheap if they do it. Also, try to get metal stems.

I have the same size wheels on my htt. I recently put Carlisle's RH load range D on my htt. I like them.

[Sport165]

Well, Found some Carlisle RH 14" LRC on Amazon for $67, it states Max Capacity: 1,760 pounds, Recommended PSI: 50, so by going with 14s I can go to the lower load rating, but x3 +new rims?

**Just priced on Amazon- the Carlisle Radial Trail RH Trailer Tire - ST185/80R13, $81/tire! More than the 14! But I can use my own rims... It also doesn't state the load size?
I will go Check around, and look into tire/rim deals!

I will continue to look around, but will probably need to stick with current 13rims at this time. If I do, I will definitely get load D.

*@Jagiven, Do you have the 13 or 14s?

[Jagiven]

13 inch, same size wheels you have listed in your original post

My 23B is a tandem axle htt

@Jagiven,
I've looked and can only find Carlisle 13" RH as 6ply/c,
However, I did find Carlisle 13" RADIAL TRAIL HD listed as 8ply/D.
I'm still looking.....
***EDIT
Ok, found this information!!! The HD model replaces the RH tire! It states under the Carlisle Radial Trail HD Trailer Radial Tire - 185/80R13 99M:::::::
"Max Capacity: 1,710 pounds, Maximum PSI: 65
This is a tire only. Wheel is not included. This model number (6H04541) is a direct replacement for the Carlisle Radial RH Series model number 6H01521"

That sounds about right, I have had a hard time finding info on these tires. Discount Tire told me about them.

[Sport165]

Yes I'm getting same HD tires at discount tire, called America's Tires here in LA...

I was able to replace with 225/50-14 on my trailer with new wheels about $225 total kept the spare the same.
