I am looking for a better trailer tire. I know it has been discussed before but lets do it again.
I have a 3 axle Heritage trailer w/ 215/75/14s on it and they are a 6 ply tire. Blew one out on the 150 mile trip home from LOTO last weekend.

6 Goodyear Wrangler HT 245/75/16 load range E with triple disc electric over hydraulic.

Four Goodyear Marathons 225R-15 Load range D. 9000 lb GVW trailer

Well, my trailer is a light weight (3500 lbs) with a tandem axle trailer so I just use regular car tires. I just put a set of Yokahama 205/70 R14 Avid D's on the trailer. They are T speed rated, even though I have no intention of pulling the trailer at sustained speeds of 118 mph, I have found that the higher speed rated tires tend stay together longer. These are only rated to 1433 lbs each which gives me about a 5700 lb GVW on the trailer. If they offer some speed rated 6 or 8 ply tires in the size you need for your trailer, I would suggest you look into those. A tire has to be better at dissipating heat to make the speed rating and that will help with longevity as well (allthough typically those tires have softer compounds so they have a lower mileage expectancy, but then again, who do you know that puts 80,000 miles on a set of boat trailer tires).

Hi,
May I take your attention on using regular car tires. I already tried those and this was the first and last time I will ever use regular car tire on a trailer especially on a tandem or triple. The side walls for most of them are only 2 ply, if for any reason you happen to hit the side wall it won't resist, when backing up you you have to make a jackknife they won't stand up to the torsion.
Regular car tires is absolutely a BIG NO FOR ME

Bridgestone has a 6ply trailer tire in that size,,,we put a set on a customers trailer friday pm.

Use tires marked "Trailer Use Only" on your trailer. Standard passenger tires are NOT designed for trailer use. If you've ever seen the side loading that goes on with a triple axle trailer when you make a sharp turn, you understand what I'm preaching here. Typically, 3500lb axles are equipped with ST205/75R14 which are rated around 1750lbs each. The heavier the axle weight rating, the larger the tire size (width, rim diameter and aspect ratio).

Not trying to talk down to anyone but just for informational purposes here's what the numbers/letters stand for on a tire:

ST = "Special Trailer"
LT = Light Truck
P = Passenger

205 = tread width in millimeters

75 = Aspect Ratio/Profile (The sidewall of the tire is 75% of the 205mm width)

R = Radial

14 = Rim Diameter

There are also Load Ratings, Number of Plys, Max Inflation Cold (Not literally "cold" but meaning not driven on), Max weight rating, treadwear, traction. Use the correct tire for the correct application. You'll be glad you did. Ask anynone that has towed an extended distance to a poker run.

I guess i'll buck the system here....All I have ever run are LTs
{Light truck} E range.....25 years & never lost a tire...I must be lucky !...Always Inflated to Max & I make it a point to not run over curbs In my truck or trailer. I have lost 2 wheel bearings over the years tho.....
