Thinking of upgrading my rims 1 size up. the tyre guy is proposing 205/50R16 (+1.4% change from current 15").

Below are the 2 brands he offered,
Michelin PS4
Continental UltraContact 6

Not sure which is good? I've heard about PS4, but wanna hear about UC6 too.

PS4 if you want better all round grip, it's going to be slightly noisier though

i've seen those cartuber all prasing ps4 from earth to sky and forth hahaha even my car enthu friends also said ps4
but i dont know how it compares to uc6, like what i'm "losing out" if i opt for uc6

thanks for reply btw

here's a short one to sum up my experience:
I've never needed to worry about wet/dry grip and braking (but please drive sensibly when it's wet la)
it's relatively durable (20k km of hard driving and still looks quite ok), ive used it for 40k km on my previous car and it still looks quite ok
it's easily available almost everywhere (unlike eagle F1/conti CPC6/bridgestone s007 where you need to place orders days before)
it's reasonably priced for what it can do

OTOH, IIRC PS4 is more on par with CPC6, and that's a tier above the MC6, and 2 tiers above the UC6

ahh okay, now the 2 tiears above UC6 explains the price diff... thanks

Absolutely PS4! UC6 is a low end category tire.

was crawling the tered and saw your reply to someone else's too, same tyre size even! 😂

*continues to do homework but skewing towards ps4 now*

Another choice I would recommend is the recently released Goodyear F1 Sport. Probably slightly less performance than PS4 but should still be pretty good UHP tire and more importantly cheaper by around rm50/pc so it should be an excellent value for money.

Thanks! Will keep in mind when changing tyres. GYF1 will still be better choice than UC6 right?

Also, if I may seek for your knowledge about tyre and wheels, do I have to take note about the offset and scrub radius?
I’m changing from 185/60R15 ET40 to 205/50R16 ET46 (both rims are from VW Polo HB and Vento TSI respectively). Apparently those online calculators said that the new rims have negative scrub radius which may affect braking and stability 🤯

Yes surely still better than UC6. I had used the predecessor F1D5 and even that was already pretty good and almost matching PS3, so this new replacement F1S would be even better.

Many cars actually have negative scrub radius setup from the factory. See article below for more details of scrub radius.

Btw for 185/60/15, actually the more exact conversion size to 16 is 195/50/16, while 205/50/16 is slightly bigger by 1cm diameter.

I actually requested the 16” to fit with 195/50/16 or 185/55/16 but tyre guy say those rims need to fit 205/50/16. So i wonder if really cannot fit or just want me to buy the expensive one?

On the other hand, regardless the price, 205/50/16 slightly bigger 1cm diameter but still can be used too right? Like, I won’t lose out the stability or braking performance.

Paiseh asking a lot. Just wanna know what I’m paying for, don’t want buta2 change then after that only find out consequences. Newbie trying to change tyres ended up so many things to worry with 😂

need to see ur rim width.. if it was 7jj 205 just nice.. 185 will be too small for 7jj... just go for ps4.. once u used ps4 u would hardly go to other tyres.. ps4 is nice just some chip off mayb after 40k... my this set currently at 55k with around 30% thread left.. going to change before cny..

How wide is your rims? If 7jj or below then can use 195. If 7.5jj then better use 205. But yes, 205 is still ok to use, slightly better grip and comfort but consequently slightly heavier too. Better you do a test fitment so can see the difference if 205 can still clear/won't rub.

Aiya my bad I missed out salient points. Yes, it’s 7J x 16” alloys. Those rims was fitted with 215/45/16 out of factory (Vento TSI) but I think that’s too much and >3% diameter change for my car.

I think with some homework (digging old posts) done and your kind inputs, I’ll just go with that rim with 205/50/16 PS4 and test fitment........after mco 🤞🏻 Thank you guys very much 💪🏻

215/45/16 is a very rare size and it actually has the same rolling diameter as 195/50/16, so it does not exceed the 3% general guide but just much wider.

btw ts, what car are you going to use the tyres with?

polo hb mk5

just thought of updating to sifus who spent time to reply my query previously
finally bought new shoes for my car - 205/50/16 PS4, manufactured 4420 (one of them is 4520)
the tyre guy suggested to test fit with 1 piece and see if it rubs the fender or insides, but all is well.
(contacted my SA who sold me the car to ask him to help ask SC if my car can fit 16x7 rims, since the rims are of the identical car higher specd variant, apparently they say can)
tried to fit my hands into the, when i'm on my old 15" wheels i can fit 2 fingers between tyre and front absorber, now i'm left with 1 finger. around 1cm+, should that be fine?

been driving around 50km around my area (i stay next to MRR2, so i can spin around abit without roadblocks, yet), so far i'm happy with it
less bouncy when crossing road bumps, slightly more obvious bumpy when running over shitty roads but i can feel the car a little more lethargic probably due to the heavier weight overall.

shared this happy news with my car friends and they ask me why I take UHP tyres when i dont always whack corners or speed (my car isn't a powerful car to begin with 😂)
i'm thinking to myself, UHP or not, at least i know they are safe to use when i needed them

tire performance reserve (if you can take a noisier ride) is like your savings
no one ask you to use it all in one place, but it's good to know that you have the buffer when you need it one day

agree agree.. it's like our savings... Better to have, and not need, than to need, and not have
