History of 10.50-16 tyres

The reason they did not fit was all the old tyres were basically 100 height ie height of the tyre is the same as the width. They had various specialist odd-ball heights but you would expect any normal tyre of the period to be equal height/width.

This construction was so standard across the auto industry that tyres used to be measured by height with no wheel size ie 30x3. Everybody knew that the tyre was the same height as width so they knew that the 3 inch wide tire would go on a 24 inch rim (height of tyre top and bottom subtracted from overall height.

When they started with radial they messed with profiles so your 265/75 is only 3/4 as high as it is wide. To match the !0.50 you would need a 265/100 which I doubt is made.

As you found out we are now forced to use over wide tyres to get the original height if we want something off the shelf or go to the few specialists around the world still building 100 profile bias construction tyres.
