Tire question

Recommended Posts

Since it's too cold to work on my fire truck, I've been doing something research. I've been looking for the build sheets I have say the tires were 34x7 all the way around. When I got it, it had 825-20 on one side and 900-20 on the other. First question is what size tire is 34x7?  Some web sites say the 825 and others say the 900.

Second question    the rims I have are the 3 piece style which I'm not a posed to using.  Is there a way to use radials instead of bias glass?

 

thanks Mike.

34 x 7 denotes a high pressure tire.  The modern balloon tire would be 700 x 20.  I think a 700 tire would look skinney but a 900 is relatively fat and might spoil the looks of your fire truck.

I was looking at 20.5 tubeless drop center rims which would have fit perfectly the 20" cast spoke wheels on a 1934 Diamond T.  The only gain was availability and increased capacity but the larger, fatter tires totally ruined the appearance of the truck IMHO.

Here is a possibility, MIke. I don't know if you will be able to read the fine print. These are tube type steel radials. G, 14 ply rated. Thanks to Derek Thille who found these tires.   -   Carl
