Theoretically possible because the thinner profile has less flexing and therefore can get more load pressure to the treads. However I personally have never confirmed this myself. My 18' now do seem to finish faster than when I use 17' before but cannot really confirm it yet.

How much faster are yours? Are they on the same car?

If on different cars then cannot be conclusive also because the weight, suspension etc. are different.

Yeah 30k is kinda short, should able to at least reach 40k km on normal use.

same driver ?

Different driving styles .

If I can get 30k on my 19 ps4s. ill be happy man . LOL

High performance tyre. Sticky.

Plus if u love to drive fast and ur car kerb weight is heavy, then no doubt it will finish fast.

you can take a look at Bridgestone re003 similar performance to the ps4.

or if you want higher performance but about ps4 price, its the continental extreme contact sport

lady driver, normally tire wear worst . they don't pump air regularly in the tires.

have u seen how she drive ?

my wife drive her forte .. take racing line in the tunnel ..

while I was following her back in my own car.. I also terkejut . LOL .

my driving style rubbed off on her.

My honda city tyre easily last 4 years, while my accord if 2 years already cukur. One is 16inch, one is 17inch. If my accord can last 4 years, I straightaway buy pirelli. Lol.

If got budget, use ps4 la. I now use ps4. No regret except pricey nia 😂😂

sometimes you gotta read/check the published specs for your tyres. comfort based tyres may have slightly thicker usable thread depth than lower profile tyres. it may not be much, like 9mm depth for 60series and 8mm for 45series. that 1mm of rubber may mean 10k km life on the road, depending on driving style/road surface etc.
