Do 40 hardness rubbers weight more than 39/38?

[Michael Zhuang]

Does a harder rubber (such as H3N in 40 degree) weigh more than the same rubber in 39/38 degree?

In grams, how much of a difference is it?

It should, soft rubbers generally have bigger air (or whatever their filled with) pockets than hard rubbers.

There is a difference in weight, but it is so minimal - even glue will outweigh the rubber weight difference (1 deg is so little....)

Unless it’s H3. But of course in that case DHS’s horrible quality control takes over and a 39 degree weighs more than a 41
