The link pretty much sums up the key ideas. Wet braking performances deteriorates as the tread depth gets lower. So you need to balance between what safety margin you need. Driving your tires down to 1.6mm with risky wet driving behaviors is not the best idea.

I honestly have no clue about Falken FK510 as there is not much public available data.

Based on my price table, here are some of the options.

Kumho Ecsta PS31 215/45R17 308
Goodyear Assurance TripleMax 2 215/45R17 308
Toyo Nano Energy NE03 215/45R17 311
Continental UC6 215/45R17 340
Yokohama Advan Fleva V701 215/45R17 345
Continental Max Contact 6 215/45R17 358
Michelin Primacy 4st 215/45R17 460
Michelin Pilot Sport 5 215/45R17 480

If your budget allows of course the best is Primacy 4st. However Continental's UC6 at RM 340 sounds like a bargain to me.

So some basics 101 about tread pattern.

for wet & dry grip, the effective contact area is the main driver. the rubber compound usually dominates and nothing much the pattern can do besides providing surface area.

While for aquaplaning the way the grooves disperse the water is highly crucial. You will normally see good aquaplaning tires with V shapes pattern and it is also made "directional" in place of asymmetrical

Pattern is one of the main contributor to noise. The more void you have the nosier your tires are. Something like mud terrain tires vs UHP tires. The difference is huge.

Alrighty , thanks for the info

FK510 strong points are wet grip & aquaplaning resistance. I'm currently using it on 225/45R19.

Since it is a UHP tire too, you can expect it to be considerably noisy.

which is the quietest tyre for c segment car?

Should be Michelin Primacy 4 or Bridgestone Turanza T005a

Good job, TS.

If the Load Index of replacement tyre is the same as the stock/as-is tyre, then similar tyre pressure on both would carry the same load.

However I suspect a replacement R16 is likely to have a higher Load Index than a R15 stock tyre, hence a lower pressure (than stock) in replacement tyre would carry the same designed loads as the stock tyre at stock pressure.

Having said that there is no harm in maintaining similar tyre pressure in a replacement tyre with higher LI, but not vice versa.

Not knowing the Load Index of both of your stock and replacement tyres, I think you should be fine and safe.

ahh thanks for the info!

Ya hmm... dilemma bro .

Im using the dunlop sp 050+ sport maxx non rft . 245/45/18 and 275/40/18 .

Was wondering will my nvh impove if i swap to primacy 3 rft ? i think its a quieter tyre for sure but will RFT degrade my driving experience in terms of harshness ?

I would say if you size has a CC6, it should be the best in comfort & noise

I had a quick look at their exterior noise performances and surprise to see dunlop sp 050+ sport maxx is rated better than Primacy 3 rft.

Run flat has an extra rubber cushion on the sidewall so that it can withstand the load of the car for certain amount of time after losing pressure. This influences the low frequency range of noise & which is mainly subjective aspect. This could be felt if you are a sensitive driver but most common drivers do not notice this.

Can you recommend comfort tyres for 235/50/R17 and 235/45/R18? Does downsizing from 18" to 17" have huge difference in term of comfort and pricing? Which size is more common?

Hi,

Can recommend which of these tires are quiet and comfortable for a G20 320i?

1) Continental UC6
2) Continental MC6
3) Pirelli P7 Cinturato

Thanks!

We know that the higher your rim size the more expensive your tire will be. Check out this table here. So you can expect a cheaper price.

I explain the effects when you inch up your tire here. The comfort level of your tire is related to the tire's construction. So different products with different target requirements will vary. But if we are just talking about size differences, in general the higher the sidewall the better your comfort level as you are able to flex more as the tire is going through obstacles. the good thing about down sizing is that your sidewall height has to increase to compensate the outer diameter. So you are effectively having a higher sidewall height which is good for comfort.

I had a quick look on my price table & your sizes are mostly the UHP or touring segment tire where comfort is not the main target. I would go with Michelin Primacy 4st as the best bet. There might be cheaper options where comfort is indirectly better as a by product of being non competitive in wet or wear. I hope this helps.

If we are just only talking about comfort & noise MC6 performed very well in comfort from the press test here against Primacy 4. Also from P7 Cinturato comparison against Primacy 4 we know Primacy 4 has a much better subjective comfort. So MC6 would be ideal when it comes to your requirements.

what do you think about china branded tyres? made in thailand ones

depending on which tire company are you talking about. Ling Long & Double Coin are quite solid but of course they do not solve target conflict at a high level compared to the premium brands. If budget is a concern, you would rather the by tier 2 brands from the premium manufacturer like Dunlop which Continental owns for Malaysia.
