Upgrading tire load range

My 2915 rockwood 2608ws came with Constancy ST 205 75 R 14. Load C. I've put 13k on them this summer with no problem. I use a tire pressure monitoring system and keep them religiously @ 50 PSI and never exceed 65 MPH. Still I want to move up to a D Load but can't find them in the 14's, particularly with Maxxis if possible. 15" tires will be to tight. So should I drop the idea of the D and just go with the Maxxis in the C? Just looking for an opinion. Thanks

I'm wondering the same thing. I'm meticulous with mine. Got them new this year and have 3k on them. I figured I'd go 2 years and switch from ST to higher load range but hard to find 14s.

What about axel rating? Will that be sufficient to handle the load?

Here's what I did - I went with Kumho 857's. They are a eurometric size, but they are a 14" LR D trailer tire. They make a 185, and 195, and 205. All of them would fit the original rims, but the aspect ratio is different than the cheap OEM garbage. I found a set of 195's, which had almost the exact same diameter as the 205 OEM tires.

And after some debate and discussion with the guys at the tire shop, we set the pressure at 50psi. I tried e-mailing Kumho customer service for a recommendation, but got no response. Bottom line is we went by the OEM sticker - 50 psi not the tire sidewall max. I wasn't trying to increase the load I was carrying and the trailer rode really nice on the original tires at 50 psi, so right or wrong, that's what we went with. Very happy with these tires and the TST pressure monitor after a full season and couple thousand miles.

Load range

I had a similar issue; lost two tires on the road and I found that our 2008 8319ss Rockwood weighs more than the total load range of the tires that came on it. I replaced all of the tires with same diameter, slightly bigger tires with load range E instead of C. Now running at 80 lbs instead of 50; so far no problems.

Recommend you upgrade to load range E providing the rim is rated for them. Keep them inflated to 80 lbs. They will run much cooler and less likely to blow out on you and spoil your day. Speaking from experience.

I did exactly the same thing about 3 years ago. Excellent tires. Did 195/82/14 to get the same circumference as 205/75/14. You get LR D, MORE load capacity, and a speed rating of 99 mph. Did the same TST 507 TPMS system. Also an awesome choice.

Try to find a 205/60/15 in E range lower profile may work
