Hi everyone,

If a car's stock tires are of 215/45/17, for safety and comfort, what changes would you recommend:

1) Reliable and comfortable 17 inch tires (can you all recommend any brands?)

or

2) Change to 16 inch rims and tires (recommend good brands for both rims and tires?)
The choices would either be 16 inch or 17 inch rims only. I'll need to clarify that I'm not an expert in cars, hence need some advice from the experts here in /k.

Thanks!

Thank for the replies both of you. Another question would be will there be any effect of changing from 215/45/17 to 205/50/17 tires? How will it affect the car (thinking about safety) and comfort? I won't be driving fast, just a normal driver.

Thanks 6UE5T, however, I'm not a tire guy, so I'm don't know about 'tread wear 400, traction A, temp A'.

So if I have 215/45/17 stock tires now fitted (reviews not too convincing, hence thinking of changing) and would like to change to better ones. Any specific recommendations based on the following criteria (won't be driving fast, if on highway usually 110 km/h - 120 km/h, max sometimes 140km/h during overtaking)?

1) Safety (better wet grip and less chances of the tire bursting?)
2) Better NVH
3) Longer lasting

1st question is, would it be better to change to 215/55, 215/50, 205/50 or stick to 215/45?

2nd question is, any specific brand/model you would recommend based on the above?

Thanks and sorry if my questions are amateurish...

most comfort should be Yokohama Advan DB, Nitto hard to say since it is just recently emerging in Malaysian market.

and yes, if you do not drive fast. eg: not over 100km/h in wet conditions, even basic cheap tires will suffice, however yes, having better tires will definitely be able to cope for emergency braking should it arises

for the 3 tires i mentioned, (for easy sake let's group comfort and nvh together):
1) goodyear
2) Yokohama
3) Nitto

however if you put wet grip as last, it'll be
1) Yokohama
2) Nitto
3) Goodyear
and depend if you want nitto's aggressive/unique tire tread styling (it is mainly marketed to american market, and it is under Toyo too btw ) and maybe slightly better performance, you can rate it above Yokohama's advan DB

For Michelin PS3, it is a jack of all trades, master of none tire.
it is quiet/comfortable, however won't be as comfortable/quiet as Nitto invo/Yokohama Advan DB. it performs good in wet conditions, however it won't ever be as good as GY Eagle F1 AS2 as that tire benchmarked by sports car under wet conditions and it is after all, GY's flagship tire while PS3 isn't michelin's flagship
That, and Michelin's tires are typically overpriced (of course one could probably argue the same with Yokohama's Advan lineup as it is their flagship tires) so personally i don't favor with Michelin tires at all

if anything, it's treadwear does last long, however i don't think it'll be any much longer than gy/nitto/yokohama.
treadwear wise its ps3 (320) > eagle f1 as2 (300) > nitto (260), can't seem to get utqg rating for yokohama, however it'll be around 300/300+ around ps3/goodyear
and long lasting treadwear tires *TYPICALLY* don't perform well in performance/comfort/nvh as they are harder tire compound

not for Advan DB, although iinm their advan db does not have UTQG ratings as they tend to market advan sport over America since most oversea customers do demand performance in their luxury vehicles, not just comfort/nvh.

advan sport isn't exactly a comfort tire as you can see.
latest advan sport v105 (also uses their orange oil compound) are 240 treadwear rated

and oversea advan db isn't widely market which is why i don't think they have a proper UTQG rating.
That said, the old DB e-spec, has a 460 treadwear rating

I'm doing some comparison on this too...

Any expert can share whether 225/45r17 is a good option or not?

My rim is 7.5" wide... in term of comfort, will it be much better compare to my ori 215/45/R17?
I don't mind sacrificing performance for a better comfort since fetching my family most of the time.
Thanks.

Thanks for the feedback..
Been searching around and seem like the price for 225/45 is almost 20% more expensive compare to 215/45.. 

guess I'll give it a try when it's time to change my tyre.. maybe in another 1+ yrs... 

never try used tires b4.. any idea how much each donut cost?
