Weight Differance: Bias vs. Radial

Just wondering which would be heavier a Bias tire or a Radial tire? I am just referencing the tire itself not the wheel and tire. So for example take the IROK 36x13.5x15 Bias and the 36x13.5x15 Radial straight off the manufactoring lines... Which weighs more?

I was thinking bias would be heavier however, late yetersday afternoon I spoke with Interco and they gave me the following specs:

IROK Radials:
36x13.5x15 81lb
37x12.5x15 77lb

IROK Bias
36x13.5x15 66lb

TSL Super Swamper Bias
36x12x15 65lb

I thought for sure Bias ply tires would be heavier..... The only reason I am posting is because when I talked to them it sounded like I was talking to someone who was filling in for there tech question person. Has anybody else heard the same?

I have a set of old school Gumbo mudders, 40x17x16.5 that of course are bias. I just got a set of 37x12.5x16.5 G/Y MT radials, and the MTs are heavier than the mudders.

Every little bit helps, incase you have been under a rock lately, less weight is a good thing. He is asking a newb question in the newb fourm so give a actual answer or shut up.

Lowtorious,

Per Interco that's what they said... I questioned it at the time and they double checked but that's what the spec sheet apparently said.... Go Figure....

It makes perfect sense. All the weight of the radial tires is in the tread area, where the steel belts are located. The wider tire will weigh more than the narrower tire.

I have the 36x13.50x15 Irok Radials, and I've handled both the radials and the bias ply Iroks, and the radials are quite significantly heavier. Radials have a harder to puncture tread area and are much friendlier on the street, which is why I chose the radials over the bias plys, and I'm very happy with my choice.

Just curious, Does anybody know the weight of a 37x12.5x15 GoodYear MRT? I am curious to see how it compares to the Irok Radial...

Thanks,
