Yea in your case Silverstone has closed down and replaced by Toyo. Maybe the buldge we are talking about are different type of buldge - since you seem to imply that 3 of your tires that came with your car has this issue. To me that doesnt seem to be very likely. Tires going to a car manufacturer would need to pass through the tire manufacturer’s QC and then again through the car manufacturer’s receiving QC department before again another round of QC before the car leaves the car factory. So maybe thats why you arent gettng anywhere with your request.

Hi OP. Recently I've been introduced to this new German tyre GITi Sports S2.
There are little reviews on them but the individual reviews looks good.
Tire shop owner said the performance comparable to PS4/5 while being quieter and cheaper.

Wondering your expert input on the actual comparison between Giti sport s2 vs Michelin ps4/5?

Oh nice! Saw it thanks man.
Which tyre did you went with in the end?🤔

What are the best tires for 225/65/17 size wheels for a quiet driving experience?

Exactly right. Free free to use your Michelin's for a much longer time

What are your priorities? Price? Performance? Comfort?

Cheapest options which give decent performance:
- Maxxis Victra i-Pro
- Nexen SU4

Best Overall Performance:
- Michelin PS5

Best Comfort:
- Michelin Primary 4

Based on my price table, here are some options

Name Tire Size Price(RM)
Goodyear Assurance TripleMax 2 215/45R17 308
Toyo Nano Energy NE03 215/45R17 314
Kumho Ecsta PS31 215/45R17 343
Yokohama Advan Fleva V701 215/45R17 345
Continental UC6 215/45R17 (NEW UC7) 360
Bridgestone Potenza Adrenalin RE004 215/45R17 365
Continental Max Contact 6 215/45R17 388
Michelin Primacy 4st 215/45R17 460
Michelin Pilot Sport 4 215/45R17 (NEW PS5) 480

Usage is on thing, but what is your main requirement? Wet, Mileage ? or value?

the new UC7 with major improvements at RM360 sounds like a bargain to me.

CR1 should be the upgrade & supercedes NE3.

Goodyear eagle F1 Sport is gooding or not? Btw seller quote me price rm320/pcs for the size 195/50/r16...is it the price is ok?

2022...

Valve not sure, balancing free...alignment rm25

Hi all sifu, I intend to change tyre soon. The seller told me to use Dec'22 manufactured tyre instead of June or July'23 cause the older tyre rubber already hardened which is better. Is it true?
