Reducing road noise level for 225/45/18

[RENESIS VIII]

Bro. 6UE5t post 255/40 is for 18" not 19".....

I see. I got it wrong earlier. My friend asked me about Pirelli as well. Any opinions compared to Yokohama dB V551? For Pirelli, I think that will probably be Cinturato P7 as P-Zero may not be suitable...

Cinturato P7 should be ok almost like Michelin P3ST, but not the P7 all seasons.
P zero are UHP so should be noisier.....

My friend asked me if there is anything that he can do to reduce tyre road noise level in his car. Currently he is using 225/45/18 Good Year Eagle Efficient Grip tyres for this car. These are the tyres that came stock with the car. He points out that the tyre road noise is quite noticeable when driving at higher speed. So, is there other tyres that can be recommended for him to further reduce the road noise?


He said he is considering to increase the tyre sidewall profile but I told him that might cause him to scrape his tyres against the fenders.

Tell ur friend to be very careful when choosing other tyre brand to replace the GY EfficientGrip. Because his current tyre is already among the quietest tyre available in market today.

Maybe I should just ask him to try Yokohama dB series.

I'm not sure is it that the tyre is noisy or the car is too quiet which makes road noise quite noticeable. I've sat on his car before and around speeds like 80kmh and above, tyre road noise can be heard quite clearly. Engine and wind noise is quiet on his car, so all that is left is the tyre road noise.

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.
