Re: bias plys vs radial

If you have a choice, run radials on the pavement. I have bias ply tires now. They are not as road friendly (but do ok) as radials.

Re: bias plys vs radial

Biased tires are basically rubber balloons with the same amount of cord all around...while radials have much softer sidewalls with a much more rigid bottom belt for the tread.

Fully inflate a radial and the thread will be basically flat against the ground....while the biased tire will 'balloon'...

That is one of the issues with off road tires....for example, the BFG's have 3 plys in the sidewall which improves the puncture resistance but makes for a stiffer ride because they do not flex as much.

Re: bias plys vs radial

Here you go;

Bottom line is that the bias tire will form around the rock that you are driving over better than a radial. However they do not put down a flat tread to the pavement like a radial will so stopping distance will be greater with the bias. Also they will develop that “flat spot” that gives you the “thump, thump” until it warms up.

Re: bias plys vs radial

Is it a daily driver or wheeler? If it's a DD radials, if it's a woods truck bias. Bias ply tsl's or sx's are my favorite tires for wheeling and good year work horses for DD duty.

Re: bias plys vs radial

I would like to see you plug a hole in a radial tire.. [img]/ubbthreads/images/graemlins/smile.gif[/img]

Bias you can blug to get you out of the woods if your spare is junk.

How ever i would not drive on the road with it.
