New guy old subject..tires

My current wheel width is 15x5 and I have some wiggle room but not a ton, I was thinking about a 215 70 15 in D load range. Everybody talks about cheap trailer tires and blowouts galore that it makes buying, what should be a relatively simple purchase, a royal pain of research. I want something that will hold up as everybody else does, but I
Can't afford to brake the bank in the process. Looking at the maxxis it has good and bad reviews like all the rest do. I do have to ask, are all the blowout stories due to faulty tires or more along the line of improper care, such as too low of air pressure, too infrequent of use, and so on?

I went from 205 to 225 and C to E load rating a few years ago. Still happy with my choice......

Hello txfirerescue. Welcome to the forum, and yes, you have brought up the proverbial touchy subject ! :)

As has been pointed out, you have several options in 15"LT.

I'll weigh in as one who only buys LT for all four of my trailers, so that's my two cents on it.

Get rid of the passenger car tires and replace with Maxis ST tires. NOTHING wrong with the quality of Maxis and it's the ONLY brand that runs on my trailer. Lots of other brands will work for casual towing but for long distance HD use it's always Maxis.

P tires work great on trailers especially P's that use 44 psi or 51 psi and enough capacity for the load. Before tire makers gave us the ST tire all we had was passenger (P) tires or 14"/15"/16" truck tires (LT). As lowsuv mentioned P tires load capacity is required by fed regs to be derated by dividing its capacity by 1.10.

Some very good quality 15" tires to look at for your trailer;

Depending on room in the wheel well and proper wheel pressure/wheel width requirements the Goodyear Wrangler HT in a LT235/75-15 C (50 psi) at 1980 lb capacity. Most LT tire makers carry this size.

And a Wrangler HT in a LT215/75-15 D (65 psi) at 2090 lbs capacity.

Maxxis LT U-168 are a commercial grade tire with several 15" sizes and have became popular with all types of trailer owners.

Vanco 2 from Continental another popular tire for trailer users has several 15" sizes and load capacities.

I see the Yokohama RY215 in a 700R 15 D at 2040 lbs capacity is popular on some of the other RV websites.

Do your home work on the numbers.

There are many threads about tires that turn into an adversarial discussion on this forum .
The most logical solution is to improve the load rating of your tires by weight capacity listed on the sidewall .
P tires must be derated by 9 % to be compared to ST or LT tires .
The quantifiable solution is to go to a Load Range D tire ( Or E ) in the size you have .
If you have room (as I do ) you can also go up to a 225/75 R 15 tire in Load Range D , or E , or C to improve your safety margin .
The load rating in pounds capacity is more important than brand assuming you are comparing ST tires . LT tires are held to a tougher standard than ST tires .
If you go to tire rack dot com you can try searching for different sizes and you will find some LT alternates in 215/70 , 235/75 , and so forth .
There will be all of the data on tire rack to get to a 2271 # rating or higher that will give you a nice margin .
The solution proposed by WestEnd is also a good one .

Yeah I guess that would help. It's a 2006 30' four winds, weighs 5700 lbs dry. Close to 7k loaded. Original tires were ST 205 70 15 C rated for 1850 lbs.

Probably get better advice if you post the model or weight ratings of your Four Winds.
I just bought 4- ST205 75R 15, Carlisle RH Trail Load Range D for my rig. 2150 lb weight rating, IIRC.
