Hey guys,

A lot of people have been asking me why their sports car comes with 2 different tire sizes. So I decided to make a video to explain.



Let me know what you guys think and want to see more about tires.

wide tyres drift easier, right?

Actually, the previous 991 generation of the 911 had equal size tires.

It's only starting with the 992 generation that the fronts are an inch smaller than the rear. My GTS has massive 20" fronts and even bigger 21" rears... fatter and wider....

Better grip and can lay down the power on the tarmac easier at the traffic lights

Yup but this is mostly for handling reasons

Having said that, the 21” tyres are crazy expensive to replace if that day ever comes…

just curious, how many km do they last?

I can’t answer that yet… as I only have 600km on my 911 so far….

congrats on the new car

back then, Porsche's are notorious for wearing out rear tires

Thanks bro. The car is nearly a year old. I just don’t drive it very often as I actually have to rotate between 4 cars (2 in Singapore and 2 in Sydney) and wife hates the 911 so she prefers to sit in any of the other 2 Porsches or the S Class instead.

I love my 992 but it’s wife’s least loved item in my garage

oh... you're that retiree

'have to rotate between 4 cars' sounds like a chore, I'm willing to help with that

I can let you know how much lifespan for the tyres, too

Yeah. I’m that old fogey… taking early retirement next year to join my wife who retired early last year. We are both in our early 50s

life is set
should change your nick to 'hgsgmyaud' or something...

I did think of that but someone else already had aud in their nickname previously…

bro is rich rich

Thanks for your kind words but I’ll be joining the ranks of the newly unemployed next year…

Forgot to thank you for an excellent YouTube video!

1 word, "Traction"

Yes its CRAZZY expensive some even cost up to RM 2k

Thanks! It really motivates me to do more of this. I hope to spread my tire knowledge as much as possible

If you more tire videos, could consider subscribing to my channel ! Thanks ahead

21" very big ka?

My wife's daily drive SUV also 21" wor...

For a small car like the 911, it's positively an overkill...

Large SUVs have vastly larger visual mass on the side view and massive wheel arches. You would need at least 21" wheels, preferably 22s otherwise the car looks really weird.
