Bias Tires vs. Radial Tires

Bias vs. radial tire graphic

Bias ply tires are designed for off-road or agricultural applications. They are built with thick, durable nylon cords that are positioned at a 30- to 45-degree angle to the direction of travel. The layers alternate in a crisscross pattern, making the sidewalls stiffer so that the entire tire is able to flex easily. As a result, the tire provides a smooth ride and improved handling when trailering on uneven surfaces.

These tires work as expected. I was not able to mount them myself at home (I mount my own motorcycle tires), but a local tire shop handled that just fine for a small fee. I trailer my bikes to race tracks, and have had no issues with these, wet or dry roads. Of course, I'm not flying along when pulling a trailer. 348336

Review from a similar Bias Ply in Trailer Tires and Wheels


This is a replacement tire. I used the same make and designation to match other trailer tires. Pep Boys did the mounting for about $17 on the old rim (install, check balance, valve stem and old tire disposal). These newer tires have the speed rating on them with an excellent 81 MPH. Which is better than the competitors with the same tire designation. The other manufactures had a speed rating of 65 MPH. The five star rating is based upon the cost, timely deliver and that it mounted and balanced without any issues. Thanks etrailer! 437239

Quick and simple ordering process; I chose free shipping, thinking I'd get this pair of tires in 2 weeks, but they arrived in 6 days and it was easy to check their progress from halfway across the country. As for the tires: these are an exact match for those that came with my dual axle trailer, which we are using for timber and milling work in the Midwest--some 1500 miles away, so these bias ply tires have seen a load of interstate miles--currently 22,000-- as well as off-road timber work, and they have held up well. My trailer manufacturer has moved to radial tires (supposedly better for the highway), but I was pleased to find these priced right at etrailer. Class operation; will order from them again. 333175


Comments
No problems this set is right at 18,000 miles about 98 highway and interstate use back and forth to Midwest and twice to East Coast. Should replace the original pair on the other axle which are getting smooth. Will do that at etrailer, of course. Thanks.

After one year of use I probably have 3000 miles on these jet ski trailer tires. They were the highest speed rated Tire of the size I could find. They have done well. I remember being a little freaked out when I got them in the mail because three of them fit in a box the size of a small slim TV and they look like bicycle tires uninflated. spent an additional $40 having them professionally mounted at a local Goodyear dealer. 525078

Review from a similar Bias Ply in Trailer Tires and Wheels


I have had these tires on a P/U camper for a year now and I am very satisfied. I have pulled it to Co. from Tx. and have had now issues with them. I like the fact that they are rated at 81MPH and can be pulled safely at 70 to 75 MPH. When purchasing tires it is important that you find a tire to that will preform. You can find tires in this size cheaper at big box stores but you will not have the peace of mind you have with this tire from etrailer. This is the second set of tires that I purchased from etrailer in this load range and speed range. I use my P/U camper a lot. I will continue to purchase from etrailer. I have had no problems with delivery or costumer service. They say what they do and do what they say. 893851

Review from a similar Bias Ply in Trailer Tires and Wheels


Overall I am happy with my purchase of these tires. I wanted the higher highway speed rating (M 81 mph) and that is what I got. I rate my satisfaction at 85%. Happy with cost. Happy with quicknest of filling my order and arrival time of the tires. A little less than 100% happy because the tires are already a year old (DOT 2619). That's one less year that the comfort zone of a six year tire. I understand LIFO and I can live with it. 849782

These tires with rim came in on time and un-damaged. They fit my trailer and are still in use today. I like the ease of ordering on line and had no hiccups. When ready to buy tires for my trailer again I will certainly buy them from etrailer.com 794441

Tires are great, maybe best 12" available. But etrailer flattens them for shipping and t was not able to get them to return to shape, even with heat. Had to take to tire shop for install. But I expect great service from them. 757173

I haven’t even opened the box yet. But let me tell you WHY I purchased these tires. I’ve had two blowouts on my golf cart trailer. Yes, I run it fast. Usually around 70-75 mph. And these tires are rated at over 81 mph! I’ve got to give them a try. 721619

They are alright in my book. They held up to decently high loads and they have good treadware. I put 40,000 miles on them and only had 2 flats dude to nails. Still have yet to ware one out all the way. They only thing I would like better is on one of my tires had some belting show before I even put it on. It was molded far offcenter and inside the tread valley you could see the nylon 717558

Very good value. Broke Springs on a small center console tender trailer, thought OH boy how am I gonna find parts for this. Searched on-line. Found etrailer and BAM = problem solved. Got springs, shackles, bolts, even an entire spare and tire for a couple hundred bucks and THEY ALL FIT and at least as good quality as the thing was build with. Excellent and pretty quick shipping and delivery for heavy stuff. 711535

Review from a similar Bias Ply in Trailer Tires and Wheels


Got these tires for their 81 MPH rating. After about 2000 miles a large patch of rubber separated from the tire. Two weeks later the tire on the other side did the same thing. The Taskmaster rep said I must have hit something that cut the tread but I think the tread separated from the inner ply. Two tires in two weeks with the same problem seems like more than coincidence. Luckily I noticed both holes before they blew out. The third tire of the set I bought from you will never be on the ground. I won't even trust it as a spare. 581795

Ask the Experts about this Taskmaster Trailer Tires and Wheels

  • What is the Difference Between a Bias and Radial Trailer Tire
    The size of the two tires is the same but how they're constructed is what the R and the D identify. A 175/80 D13 tire, like # TTWTD17513C, is a bias tire which means the plies that the tire is constructed of crisscoross. Whereas a 175/80 R13 tire, like # TTWTRTM1758013C, is a radial tire and the plies "branch out" from a the center of the tire. Which is better for you depends on what you use the trailer for. A bias tire is generally better for agricultural use because it has a stiffer...

  • Speed Rating for ST175/80D13 Trailer Tires
    Every trailer tire will have a specific speed rating listed by the manufacturer. This can vary within the same tire size and design depending on the model and brand so there is not a general max speed recommendation for a 175/80D13 trailer tire. The speed rating will be listed right on the tire's sidewall. When there isn't a rating listed then the max speed is presumed to be 65 mph. For an ST175/80D13 bias tire I recommend the Taskmaster # TTWTD17513C that features a speed rating of...

  • Where is DOT Number on Trailer Tire and How to Read It
    What size tire do you have? There should be a 4 digit number on the tire after DOT. When reading the DOT number on your existing tire, you will want to look at the last four digits of the number (if there are more than 4), not necessarily the numbers or letters immediately following "DOT". There may be some letters and numbers between "DOT" and the date code. I recommend checking your tire again to see what the last four digits are of the DOT code. This should be four numbers, the...

  • Trailer Tire Fender Well Clearance When Changing from Bias Ply Tires to Radial Tires
    When changing out the exact same tire size of ST175/80D13, you won't have any size difference between a Bias ply Trailer Tire like # TTWTD17513C and a Radial tire like # C17513C. They will have the same diameter of 24.02 inches and same width of 7 inches. It won't impact the fender clearances at all. They can have different load capacities, ply ratings, speed ratings, etc, but the size doesn't change. The biggest difference is the way the cords of the tire are run. Radials run 90...

  • Recommended Radial Versus Bias Trailer Tires for Tandem Axle Trailer
    When using trailer tires, you want all your tires to match so they will wear evenly and have the same traction. It is not recommended to use a mix of radial and bias tires. The radial tires are made differently from the bias tires, so they will absolutely wear differently and will also heat up differently when in use. The friction from contact with the ground will allow the bias tires to heat up more than the radial. Since you often go in the bush, you will want to determine if a bias...
