Tyre noise

What's the label roadnoise figure for the road noise from that tyre and from the one you wanted?

The Dunlop SP Sport Bluresponse tyre noise is listed as 68db, which should be OK.

A professional tyre fitter ? Don't make me laugh, anyone that would fit one, odd, unordered tyre on the front of any road car is not a pro.

Bugger me, there's a lot of amateur volunteers spending their time sitting around in tyre depots and vans around the country.

I know they are out there, but why do people use them?

We'll call that a "whoosh", shall we?

Covenience of fitting at your work place; donked a tyre when pushed towards the curb by a heavy lorry.

But why did you accept that tyre, fitted at the front?

Someone doing a job is not a professional at it unless they can display competence to do the job properly. Obviously I should have realised that 'mobile tyre fitter' and professional are not the same thing at all, and should not have mentioned it. It just amazes me that a bloke in a van is allowed to fit one of the most important safety items on a car without proper training or updating in important details of the job, what else did he do wrong at the same time? I know quite a bit about surgery, but I would not dream of working on a human unless it was life or death.

Not great for tread wear, but they should have lasted more than a month.

You should never have different brands on the same axle , Grip under acceleration , braking and cornering will not be the same infact in some EU countries you can't have different brands on the vehicle full stop.

Which, of course, they'll be with a new tyre and a 3/4-worn one, too. Or one that's underinflated a bit.

Sure, mismatching isn't ideal, but I'd much rather have mismatched decent tyres than matched AliBaba-brand-it-yourself ditchfinders.

Really...? Which ones...?

Has the wear on the other side increased as well?

Does the new tyre have the same load rating as the other tyres?

Have you had the tracking done? If you damaged a tyre the tracking has almost certainly been put out as well.

Spain requires identical tyres on each pair (ie fr. pair or back pair)

The tyre wear is fairly even.

Dn't know, but assume this is not really an issue for a 1400 Kg passenger car carrying 1-2 persons driving non-agreesively and within speed limits.

Tracking seems OK, but can it really affect tyre noise? And why is it assymetrical?

I was first thinking that there might be a clue in the tyre name: "Bluresponse"; maybe they use harder compound to reduce rolling resistance? But then the published noise number 68db is quite good.

But I have noticed is that the noise is very sensitive to different road surfaces. That puts some doubt on how they obtain the noise numbers.

Never had any problems with acceleration , braking or cornering.

Yes, it is. Check.

It's a standardised lab test.

This is beginning to sound like a Troll...

I wrecked a tyre on a badly lit "traffic calming" kerb a few years ago. At midnight in a dodgy area of Manchester I chose to drive the 1.5 miles home on the flat tyre.

E-Tyres fitted a matching replacement next day. I would not have accepted an odd tyre under any circumstances.

Road noise is a distraction, some road surfaces are deliberately made noisy, like the slip road off the M60 at the Ashton junction. It makes the driver speed conscious as he approaches traffic signals. ;-)
