"Eu tive um problema com os pneus."

Translation: I had a problem with the tires.

[NickGiorgio]

I hear "pneus" aaaaaaaand my immaturity shows.

[JCMcGee]

Sim...sua pneus e pequeno demais.

[PabloB.1]

hahahaha

Now I got the joke of yours...

[AnCatDubh]

Should there be an epenthetic vowel between p and n?

[plaureano]

Not any more than in the English word "pneumatic" having to do with air and sharing the same root.

[PabloB.1]

Hi,

Exactly, you should spell it as just as in pneumatic.

it seems so: https://forvo.com/word/pneus/

[MatteoFeli]

why he wants me to write "with my tyres" if he didn't say " com os meus pneus"?

[margaritaguese]

Well this is not possessive. It's just I had a problem with the tires, not MY tires.

Why are 'wheels' not accepted here?

[ThanKwee]

Wheels of cars are made from steel, aluminum etc. The tires are made from rubber. The tire is attached to the wheel. Note that you never say that you have a flat wheel. ;)

wheels = rodas

a wheel = https://konigwheels.com/wp-content/uploads/2015/05/KONIG_INTERFORM.png

"Problema" is always masculine I'm guessing?

[Paulenrique]

Yes, words that end in "EMA" are usually masculine.

[Blackpool_Jack]

Well that will save me a fair bit of contemplation time...it's a shame you guys didn't decide to make all words ending in a feminine and those ending in o masculine....
Appreciate your time and guidance as always. Obrigado.
