Impossible to answer without details, except that countless riders do descents like that and worse without issues, even on a tandem.

Here are some hints.

The first thing is to use the "air brakes".
Every bike and rider has a terminal velocity where wind drag is is equal to the effects of gravity. At terminal velocity you stop accelerating and coast at constant speed until something changes. So the best way to descend without hitting brakes is to get comfortable nearer to your terminal velocity, where the wind is doing most of the work.

Also keep in mind that wind drag is proportional to the square of wind speed, so once you reach 15mph or so it ramps up vertical quickly with small increase in speed.
....

Use the brakes intermittently to trim off some speed then let the bike accelerate back towards terminal velocity and repeat the process as needed. You can also use your body and posture to slow your bike by being more upright and raising your wind drag as much as possible.

So, once the wind becomes the main brake, and your rim brakes the auxiliary, you won't be heating the rims nearly as much.

Sadly I see so many riders dragging their brakes and heating their rims at speeds just a few miles an hour below terminal velocity where they wouldn't need their breaks at all.
