I have a car hauling trailer and need to replace 2 of the 4 tires. Need a little education and recs please.
Trailer is 18' all aluminum double axle - 7,000 GVWR
OEM tires are Trailxtreme ST 205/75/R15 6 ply, Load Rating C, manufactured 11/2016
The trailer gets quite a bit of use hauling a 2004 Jeep Wrangler. At least 5-6 trips per year of 1,000 miles + round trip. Trailer is around 1,500 # and Jeep around 4K # - total weight 5,500 + pounds.
Questions:
Is it OK to just replace 2 of the 4 tires, as long as I dont mix old/new on same axle? Which axle best for old vs new?
Any reason to go up a Load Rating from C to D? If so can I mix the old LR C with new LR D?
Anyone ever heard of Trailxtreme tires? I can find them on a Google Search?
What brand trailer tires do y'all recommend?
Anything else to consider?

Any help appreciated.

C to D does no harm. Might last a little longer.

Mixing old and new on a trailer also does no real harm. It's not like you can't tell them apart. You only probably want to avoid putting both old tires on one side together.

Seems like when trailer tires start to go, they all go pretty quick. I think you should expect to replace the other 2 soon

But I don't think which axle really will matter.

My 2016 carhauler gets about the same amount of use as you, and I just recently had one blow at 75mph.

Will be replacing them before the next trip with Hartland ST load range E at Discount.

I put Hartland tires in load range F or maybe G in my 5th wheel last month and they did great up to Colorado and back.

Carlisle tires from walmart. I ordered online picked them then had rodriguez tire mount and balance for cheap.

Just out of curiosity, which two tires do you think need replacing?

If the worn tires are on the same axle (front or back), you might consider how your load is balanced or your hitch height. Chances are one axle is carrying more weight than the other.

I usually replace trailer tires when I blow them, so don't often have a choice on brand. Just whatever I can find for the spare rim to stay on the road. Walmart tires are usually good enough. I wouldn't go less than load range E.

Not related to wear - 1 tire got ate up when a fender came loose and the other got several punctures that Discount wouldn't fix (too close to sidewall..) and I couldn't get plugs to hold. I inspected all the tires and wear was remarkably almost identical - much more than I would have expected.

I went with the Hartland ST Radials in LR D - put them on the rear axle. They seam like a much more robust tire than the OEM.

Would still like to know something about the OEM tires - Trailxtreme. The trailer was high $$ top of the line in every way I could evaluate, but cant find anything online about them.....

Thanks for all the info - as always TexAgs OD knows sheet.

I have had too many trailering experiences early in my adult life. #1 lesson stay away from carlisle tires!
Sidewalls are like paper thin. Get 8-12 ply
Dont run at 75-80 mph. No trailer tire is made for that especially in the heat. Expect issues when you least expect it if you do. Dont keep any tires over
5 years old

I switched my boat to Goodyear endurance load range D. Haven't had them long enough to know how they'll do. I've had two Carlisle's go bad.

Roger. Sounds like you got 'er whipped.

DO NOT buy Carlisle tires! I bought Maxxis load range E and no problems since!

When it comes to trailer tires:
1. Replace based on age not wear
2. Replace before you need to
3. Replace with American made.

Gonna offer a dissenting opinion. Cheap, imported 14 ply tires are a Godsend to running tires on trailers. They're just going to ride a lot rougher. If you have a heavier trailer, put the 14 plys on it and forget it. (If it's a lighter trailer with 3500# axles, you might not want to.)

ETA: I see this is a light trailer. Replace the two that are bad with load range D or E tires. You can even use radial tires. They all stink compared to the 14 ply, but they're better than the C's.

Look on Amazon for trailer tires. Lots of good deals.

What kills trailer tires is sun damage. I even built a new barn to store trailers in.

Do you know off the top of your head which brands are American made?

I am all for over doing it on anything vehicle/trailer related. I hate being broken down on the side of the road, and I usually have a fairly valuable vehicle riding on the trailer. I dont mind spending a little extra on trailer tires.

Question is where do you find the higher rated tires - E and above? I was in a little bit of a bind and needed tires quick so I didn't have much time to search, but for my size (205/75/R15) I couldn't find anything higher than LR D at discount/NTB etc?

Thanks again for all the input.

My Hartland STs were 225/75/15. They are load range E.

Your smaller tire size might be what is preventing you from getting into E range?

I can tell you from experience RUN AWAY FROM CARLISLE TIRES. I also have had may bad experiences with them. The best trailer tire I have found but expensive is Goodyear Workhorse.

Goodyear were the only ones I found when I last looked.

Goodyear Endurance are the only made in USA trailer tires.
I have your same trailer except its about 30 years old and have been extremely frustrated with the selection of 15 inch trailer tires. Basically, its the China bomb tires or the one Goodyear choice.

I bought the Goodyears with load range E and had a blow out on the trailer on the first trip out with a total of 38 miles on the tires! My load weighed about 4500 pounds, which is about 1000 pounds under the trailer's capacity and significantly below the tires rated capacity of 2800 pounds per tire. I guess the tire was defective, but I'm worried the others will fail too.

I've looked for 14 ply tires on line and only found one and its a Chinese tire. I"ve also looked for 15 inch light truck tires with load range E and have not found any.

I recommend the highest load capacity tire you can get. Of course, I followed my own advice and still had a blowout!

Report back what you end up doing. It isn't fun dealing with a blowout on the Beltway!

ALWAYS air up any trailer tire to its max cold pressure!
