become tired/tires

What if you [become tired/tires] of this sports car after 5 years?

Are both choices equal?

Thanks

If you are tired of the same food every night  => that is to say the same old food makes you tired

Tired/ exhuasted/ pleased/ intoxicatd and many other past particples are commonly used as adjectives. Some call these stative partciples which are passive in nature.
What if you become/get /  tired of this sports car 5 years from now?

Yes, I'm serious.

No, it's not the same. It's the same as "I am tired OF" or more accurately, "I am becoming tired of..."

To tire, as in, to become bored with, no longer interetested in.

I am becoming tired of his constant whining.

I tire of his constant whining.

My dictionary mentions that usage, so it must be acceptable (at least to someone, in theory).

I am tired of politics.  (current state) ["stative"]

I tire of politics quite easily.  (= I [get / become] tired of politics quite easily.) ["inchoative"]

The same pattern of stative (is) and inchoative (becomes) applies to several other verbs.  The second sentence in each pair below has the inchoative meaning.

They're scared.  They scare at the slightest noise.

You seem to be embarrassed.  You seem to embarrass easily.

The leaves are dried.  The leaves dry quickly once they are removed from the branches.

The pipe is ruptured.  The pipe ruptures as soon as the pressure increases.

This plain is flooded.  This plain floods nearly every year in the spring.

The balloon is inflated.  The balloon inflates quickly with compressed air.

By the way, does this rule apply to all the stative form of the verbs? 

*I interest easily won't do, of course, but yet I embarrass easily might work, as I tire easily does.

These verbs are particularly few and far between for those which use personal pronouns like I and you as subjects.  The following examples are arranged from not very likely to very unlikely.  Like so many other phenomena in English, I don't think it's a matter of yes or no but rather of a continuous shading between quite possible and quite impossible.

?I frighten easily.  ??I puzzle easily.  ???I console easily.
