Reducing road noise level for 225/45/18

[C99D-MMC5537]

I think I found one reason for the noisy road noise. This is because the tyres are actually run flats.

Yes. I think so. GY EfficientGrip RFT type one. Some europe forum also complaining about this tyre noise and harsness due to stiffer sidewall. Also on same car F30.

Price is expensive as well. I've just checked and it costs like RM1.5k a piece.

So, now if my friend changes to any normal rubber tyres, road noise should be reduced?

If his is with RFT tyres, means no spare, so if change to normal tyres better get repair kit ready....

I better tell him this when he change to normal tyres.

So, now that the noise is actually due to run flat tyres, then I guess the noise is still lower even if he changes to UHP tyres like P7 Cinturato?

He can try Continental Conti Seal tyres also. Not same as Runflat that have harder sidewall, as these are self sealing tyres....
But the tyre models might not be quiet type pattern....

Then to be safe, I should suggest Yokohama dB or Michelin P3ST. He asked about Michelin because his other cars at home is using Michelin. I told him Michelin tend to be pricier. He ask me why, I say probably due to brand name?

 

[vr2turbo]

Michelin, Continental, Pirelli, Bridgestone and Goodyear are brand leaders in tyres, so prices are higher

But looking at Michelin, their tyres are the most expensive ones by quite an amount? For example XM2 and PS3 compared to their other equivalents.

For XM2, yes high price. For PS3 is not actually, if you compare to GY, you need to compare to F1-D5 which is almost same price. Of course if you compare to NCT, Duraplus etc, then it looks more expensive.....hhahhahaha

Then like Continental they don't have CSC models in 15", if 17" up their prices not cheap either

Compared with RE003, PS3 is more expensive. For Toyo, is it T1-S?

Yes, but not much. Toyo T1-Sports don't have small size, maybe T1-R

 

[RENESIS VIII]

T1R is suppose to be UHP? I was thinking PS3 is in max category.

PS2, PSS and now PS4 are higher.......

The bigger the size, the more the price difference between say PS3 & F1-D5. If just smaller 15-16' sizes then not so much difference but starting 17' can be rm100 or even more per tire. back in 2012 when I bought my F1-D5, it was definitely >rm100 cheaper per tire than the PS3 of the same sizes, maybe even close to rm200/tire, so multiplied by 4 then become significant difference (it's like I can buy 5 F1-D5 for the price of 4 PS3). But maybe now PS3 prices has dropped a bit.

CSC models can be even more expensive than PS3, at least similar price level.

After PS3 prices drop a bit and RE003 seems to increase the gap is less, at least up to sizes 17' which I was checking about 9-10 mths ago but still if multiplied by 4 tires then comes up to a few hundred RM.
T1 Sport is also not cheap, almost premium pricing too since made in Japan.

 

[6UE5t]

Like me, most of the time performance is first.......

Yup, plus I listen to loud heavy metal music so noise is not a big issue for me!

Yup, recently PS3 drop price. Like my 215/45R17 used to be RM530, 6 months ago 460, now I think 430 only....

I think if you try on my friend's 320i, I think you will feel that the noise is quite bad since around speed 80kmh, the noise is quite apparent already. Considering the fact that the car is a new car, I think such noise is not so acceptable for him.

Why does it drop so rapidly? Due to PS4 coming out soon?

 

[vr2turbo]

Don't know, maybe need to be competitively priced.....

 

[RENESIS VIII]

Don't know, maybe need to be competitively priced.....

Or about time to be phased out soon? Like PS2.

 

[Wanggot]

Just asking, at a budget Rm500 - Rm600 what are the recommended brand available for size 225/45/18? Is there any size 235/45/18 available in market? Thanks and cheers...

PS3 probably will when PS4 comes but PS2 still in the market. Not sure when will phase out

Oh, din't know PS2 is still on market. Never seen before any cars on PS2.

PS2 start at 17" but now according to Michelin website is 255 width, so basically their sizes starts at 18", so to see what cars have them will be those sports cars and being premium prices will be mostly on those expensive cars.....
