Message:
Okay I got a question. What is the real difference between a radial and not radial tire? I want 31" Interco thornbirds, are they radials? I don't think they are. I don't use my truck as an everyday driver, and I don't do very much in the mud, simply because there is nowhere to go in MD. I'am not that worried about the rain, thats why i bought a 4x4. the thornbirds look awesome, but will they hurt my speed if they are not radials?

No they will not hurt your speed for not being radials but those thornbirds are REALLY noisy tires going down the road! Hope you have a really good sound system!!!!

The difference is the way the fibers in the main part of the tire are laid-out.
A bias-ply has the reinforcing fibers zig-zag across the tire at an angle while radials have them running across the tire patch.
This type of manufactoring lets the radials have:
1. softer sidewalls
2. a more stable, stiffer tread
3. better fuel economy
4. run cooler for longer tread life and in general a higher sustainable top-speed.
Thats why most off road tires are mostly rated for under 100mph while radials are up to about 130mph.
I hope this helped

If you do any highway driving, I wouldn't recommend the thornbirds. When you find a tire you like, be sure to check the speed rating and temperature rating for it. Tires with basic polyester ply in the body of the tire don't usually have high speed ratings, as polyester expands as it heats up, so going to fast/generating too much heat could be a bad thing. Higher performance tires usually have nylon as well, which contracts as it heats up; when the polyester expands and the nylon shrinks, the shape stays the same (opposing forces), which allows it to move more safely at higher speeds. In short, diameter isn't the issue, the materials and purpose the tire was intended for are the important factors.
