Time to change tyres
 

Hi,

It is getting close to tyre change time, and whilst I have lots of experience on the comparisons between Pirelli Pzero, Michelin PS2 and Goodyear Eagle F1 Asym, my tyre of choice is the Goodyear, due to them being the quietest. However, I have just noticed when looking that there is now a new Goodyear option in my tyre size (265/40r20) that is still the Eagle F1 but with SCT - Sound Comfort Technology. Press release says reduction if tyre noise by 11dB, which reduces cabin noise by 4dB and if course if that I true, it's a no brainier.

Anyone tried these yet and have any feedback, as all reviews I can find relate to the non-SCT version.

Cheers
Mark

If it makes any difference, I've just bought two Avon ZZ5 tyres. It's too early to have an opinion on them but they have good reviews and they are marked as A rated for wet with 70db for noise (looks like 1db more than F1 SCT) . Plus they're made in England.

I run the Goodyear Eagle F1 Assymetrics on my cat at the moment. I've mostly fitted F1s on my cars and have always been happy with them - the GSD3 was amazingly quiet.

I'm hoping to try on a set of the Michelin Pilot Sport 4S tyres on mine next:

Looks like the technology has been around a while, was actually launched for the A8.

I wonder if a puncture repair would still be possible!?

Thanks for quick responses guys.

I can't find the Avon's available in my size, and whilst as you state that at 70bD they are 1dB more than the F1's, I think you are looking at 19" spec, as the F1's move up to 71dB in 20" guise.

The F1 SCT spec states the same dB value as non-SCT, as both the 11dB and 4dB reductions are both "up to", and hence they can't quote any benefit. However, as noise levels double/halve every 3dB (or somethinng around that value), it has the potential to roughly halve the interior noise.

Mine is an April 15 reg car, but checking with Audi, physical build date was Dec 14. Tyres on car are original fit F1's (16k miles) and I can't find any markings to suggest they are already SCT.

Interesting point on puncture repairs - probably a good question for me to pose to my fleet tyre provider, as might get a response via that route, as Goodyear unlikely to respond with anythinng other than marketinng BS at a consumer level.

Cheers
Mark.

That is my plan. +++
Currently on 18" winters with a set of bare diamond-cut FE 20's locked away for the spring/summer awaiting availability of PS4S in the right size. :cool:

A8 is very quite car anyway. For me tyre sound level is not that important. The price is obviously important or to be more precise value for money, in terms of performance most important is the grip level, especially at the conditions where it's normally low like cold and wet. Second is ageing in terms of change of hardness and loss of grip due to age, then wear, then ride comfort and noise and fuel economy come in last, I mean I don't try to sleep while driving so don't need them to be quite I will not set any fuel economy records with a V8. The tyres are the only thing connecting you to the road and even if you do not drive hard or on the limit at the time of emergency it could make big difference, it does not matter how good your brakes or steering are if you do not have enough tyre grip to keep you connected to road. I have Eagle F1 tyres made in 2012 on 8 that I put on car in 2014 and grip has been poor since start, especially in wet and cold, if it is 20C+ then it's kind of OK and grip is getting worse as they age. They are quite I'll give them that and comfort is not bad as well but I will definitely not buy another set. From the Avon I only had ZZ3 on A6 when bought it and they were horrible, mediocre grip on warm and dry at best, poor grip on cold and wet and wore out quickly, I have seen Korean makes perform better.

I like the Michelins best and in fact I like winters more which are great for 90% of year of UK weather, can get a bit floating if temperature is 25C+ but still doing fine. Great grip in any conditions, not much loss of grip due to age and last very long. I have not tried their new CrossClimate yet so they could be good contender. But obviously any winter tyre and probably CrossClimate as well will make more noise and be worse on fuel economy.

I've had a fair few D4s the last couple of years, all on new tyres - Goodyear Continental and Pirelli all seem to be the OEM fit from new - in 19, 20 and 21 inch variants the difference was negligible between them all.

My advice, go with the best price +++

highly recommend these guys for tyres, supply only, but they do price match+++

Quiet compared to what?
 

Hi,

Should I worry? On anything but "billiard table" smooth roads the noise intrusion in my D2 is bad in my opinion. :tuttut:

I haven't had many high end luxury cars (oh, yes: ANY before this! :ROFL:) but have travelled in Mercs, Jags and one Lexus. All were much quieter.

So tell me: do I have a problem??

Robert

Cant comment on a D2 but in my opinion the D3 and D4 are pretty quiet cars in terms of tyre noise.
I've been equally happy with Pirelli Pzero Nero's and Goodyear Eagle F1's but the F1's seem to be cheaper at the moment. I've had Nankangs and Kumho's and both were poor in terms of grip but lasted well for the money.
Each to their own but skimping money on tyres especially at this time of the year is madness.

D2 tyre noise
 

Hi,

Maybe the problem with my D2 road noise is that it isn't a D3 or D4! :ROFL:

Robert

I have the CrossClimates on my Volvo. They're EPIC! Much quieter than my old Goodyears NCT5s or Michelins Primacy 3s. I've not tried then in snow yet but I have on hard frost and they provided more grip in those conditions than I can ever remember having. Actually makes my RWD car driveable in bad weather.

I didn't think CrossClimates were available in A8 sizes. ;)

Goodyear Eagle F1 Asymmetric 265/40 r20 194Y silent comfort technology ordered and sent to my local Audi dealer for fitting at the service on 6th March. Can't wait to see if there is a marked difference.

Cheers

Best tyres hands down for low road noise and great wet grip are landsail LS588

My friend first recommended this brand when I was not only complaining of noise but also aqua planning with my pirelli, and continentals. ..

I thought there is no way I'm using them on an A8 (dirty budget ) I was thinking .... then I drove his A8 and it's safe to say before I'd drank my cup of tea I ordered a full set of them.
Absolutely blown away by them. They are amazingly quiet, they handle really well in all conditions and give you great confidence in the wet.
I couldn't understand how a non brand can a achieve this .. then I realised there owned by michelin .. and even the big brand we know today started off as a nobody that no one had heard of before and now Pirelli are one of the biggest brands in the world.

You will be blown away by the performance I will only be fitting this tyre from now on

This technology - essentially a foam inner - is the same as used in Contisilents, who state (for their tyres) that puncture repairs aren't possible, and my experience is that this can be done, but it's a lot trickier, and often not worth doing.

Essentially, the repairer has to:
(a) find the hole (under the foam inner),
(b) cut away the foam over that area,
(c) fix the puncture, and
(d) then re-cover the puncture area with the foam.

All of which takes time - and probably costs more - and I've been told by Kwikfit/National/others that repairing like this can cause the tyre/wheel to be become more unstable than the original tyre. For all of these reasons, I'm unlikely to refit Contisilents when I replace these shortly, but likely to go for Michelins instead, and put up with the increased noise.

Really??
Previous set I've were Michelin Pilot SS, I loved the grip, don't care about the noise as exhaust or music cancels it out, but wear was horrible.

Went back to Pzero and they are horrible, TC comes on all the time, back steps out all the time, so I'll be after a new different set soon.

How many miles have you done on them so far??

Tyres fitted today, and just done 25 miles, mostly on motorway and dual carriageway and they were noticeably much quieter than the non-SCT variant of Goodyear Eagle I had previously.

Also had its first service at 18k miles and matrix beam checked out, which has been reset, so a happy bunny now.

Also rear footrests have arrived, so those are installed too, so hopefully all set for the next 18k miles.+++

I managed 19000miles but to be honest at half the cost of Pzeros you can effectively do 40k for the same price.
I've moved back to Pzeros just has a full set fitted and have to say it's rather noisy again.
The LS588 were a fantastic tyre.

What have you just fitted ?

Hi Ian,

I fitted Goodyear Eagle F1 Assymetrical SCT, and a couple of weeks on and still fantastically quiet and smooth, especially noticeable on the rougher bits on the motorway, where the differential between it and the super smooth bits is much less noticeable than with the prior tyres, and indeed Pzeros - I had those on the last D4 albeit 19" and could not wait to get rid of them, still not as bad as the Michelin pilot super sports though - they were really noisy.

Cheers

How wide are yours
 

Looking at replacement tyres at the moment. I currently have 9 inch 19's wearing 235 wide Dunlop winters. The door sticker also says 255 for 19's and 265 for 20's. I'm looking at 21's and wondering how far I can stretch... Landsail have a very tempting 295 but a stretch too far?! I've looked at the calculators but interested in any experience of being creative width wise. I appreciate the impact on speedo readings if the rolling circumference changes too much and that I'll need make sure I have sufficient clearance. I'm not wedded to anything in particular just interested in experiences.

I've got 295-25-21's on my D2 but they are on 10.5" wheels so I would think that would be quite a stretch

That's interesting thanks for the info. I read some chatter suggesting theres quite a difference between brands but too wide is too wide. I have rims so need to sort tyres. I might try and pick up some used 275/35's off ebay so I can get them on the car and go from there.

Manca, you might want to check the insurance position of putting tyres on that are not to OEM spec. Some insurers see this as a modification, and if not declared/approved and you have an accident, they may not pay out.

Thanks
Mark

That's a good point Mark thanks. I've given them the heads up on the rims already. Another reason not to be experimental

Fortunately, no such issue with part-worns, thank goodness :)

Thank goodness indeed. I have four 275 35 21 pzeros on their way with a reported 7mm+ each. Just need a mobile fitter now

Just reviving this thread rather than posting a new one...

I'm about to replace all 4 tyres on my D4 which is currently running slightly oversized 275/40/20 Avon ZX7's on 20" OEM 10-parallel spoke wheels (PRK). They've been okay, no issues with grip/feel/water etc., but I do find the noise levels in the cabin to be fairly high, particularly when on crap roads (i.e. the ones where they throw glue & gravel down rather than resurface with new tarmac).

The majority of time the car is on A roads rather than motorways, and I'm looking for a mid-range tyre on the original 265/40/20 size, which is going to be as quiet as possible. The Goodyear SCT versions sound good, but perhaps a bit more than I'm looking to fork out. My local tyre centre has offered Davanti DX640 for £135 (inc. fitting/vat etc.), which are (apparently) manufactured by Continental?, or a budget one, Accelera IOTA ST68 at £85!! High-end wise, it would be the Goodyear
Eagle F1 Asymmetric 3 at £185 each.

While the Accelera tyres are a great price (and rated at 68db), I worried they may be a bit too budget? Has anyone had any experience of these?

I've also considered dropping the wheel size to 19", but not sure that'll make a huge difference.

Thoughts, opinions & suggestions very much welcome +++

I find the Acceleras are a fair bit louder than their rating implies. Grip and wet performance is directly proportional to price although some members on here do like them.

The Eagle F1 Asym 3 is a terrible tyre. Its noisy, squirmy, bouncy, and ugly to look at. I have a set which I replaced after only a few thousand miles because they were so awful to drive on. Its such a shame because the Asym 2 was superb in every way the 3 is bad. Much as I dislike the Acceleras, I'd choose those over the Asym 3 if they were the only two options. Luckily they aren't!

Dropping wheel size with the same width tyre won't make a lot of difference - its the footprint of the tyre on the road that makes most of the noise.

Welcome btw +++

When I had my D4’s, I ran with 4 different tyres. Pirelli, Michelin, Goodyear and Goodyear SCT.

Pirelli were the most fuel efficient, Michelin were noisy, but long lasting, Goodyear were quiet, but not that long lived and Goodyear SCT even quieter, but again not long lived.

D4’s do suffer from a little more tyre noise, so for me it would be Goodyear SCT all day long, as the slight reduction in noise was worth it.

I'm on 19's but would also dismiss the Goodyear Eagle F1 as they didn't last well.
I switched to a set of Hankook Ventus S1 Evo 2 last time and I am very happy with them. A lot cheaper than the Goodyear and have done way more miles.
No issue with noise and plenty of grip.

if you look up landsail on dtl-chinese-tyres.com you will find that this company is aiming to compete at the top of the market , even in aircraft tyres
I bought a pair to try on the front of my D2 and couldn't agree more about their performance , I selected them on the basis of wet performance , compounding and noise

how did they produce such a good product in such a short time ? same way as bridgestone ....head hunt their top technical people from the majors
