Tyre care.

[DMK/Happy]

What tyre conditioner or treatment can be sprayed on tyres to prevent dry rotting between the tread water channels ?

If you have rotting tyres then they need changing.
Like any rot once set in you wont revert it.
There are many things ppl put on the sidewalls, but on the treads ????

Just noticed tiny hair line cracks in the water channels between the treads on one of our cars,tread depth appears ok,

I don't believe that there's anything that you can do once its started.
The tyre compound itself contains an agent that helps to keep the compound supple and prevent this cracking, but its only activated by the tyres getting up to temperature through use, hence low mileage cars will suffer from this and high mileage ones wont.
UV light is a big factor in triggering this, hence you'll find caravan owners covering their tyres when their not in use.

What's the ‘DOT code’ on the tyre?

The first two digits tell you the week number and the last two indicate the year the tyre was manufactured. DOT code '3909' means the tyre was made in the 39th week of the year 2009.

Tyres are considered to be “new” and fit for retail sale up to 5 years from the date of production - although I wouldn't buy any more than 6 months old.

When in use, it is recommended that tyres are replaced when they reach 7 to 10 years old, (6 years in the case of caravans or trailers), although I would not consider driving a car with tyres more than 7 years old in any circumstances, and prefer my tyres to be less than 6 years old.

Burt Munro would know what to do
(Worlds fastest Indian)

Jim Moffett : What are you doing?
Burt Munro : [referring to his KIWI brand of black shoe polish] Well, the soft shoe polish fills in the cracks. Makes the tyres look spick and span, good as new. Cheaper than new ones anyway.
Jim Moffett : I didn't see that.

Like NJS5 has said it doesn't matter about the tread depth it is the age of the tyre that is important. Sounds like they need changing. Hard to do when you have lots of tread depth left

This is indeed a low milage vehicle,5K per year.

Thank you,interesting.

The tyres were manufactured 26 week 2016,and would have less than 20000 km town driving mostly.

So currently 5 years old, and cracking up; in these circumstances I would bite the bullet (rather than the dust !) and change for 4 (or 5) new tyres now.

ROSPA recommend:-

Tyres showing:-

Cracking/crazing on the side wall of the tyre, caused by its flexing
Distortion of tyre tread
Deformation of the carcass of the tyre

should be removed and not put to further use.

They add:-

Vehicles which are stored for significant periods (motorhomes, caravans, ice cream vans, classic cars, etc) are more likely to need to replace their tyres at a younger age even though the tread may well have hardly been touched. This is because tyres have agents in their compound which are squeezed through the rubber when in use to inhibit the ageing process; if unused for some time, these agents do not work, thus increasing the speed of the ageing process. Tyres fitted as spare wheels or used on caravans and trailers may age prematurely.

A cracked tyre is a weak tyre.
They rotate alot, they get got, they suffer big bumps on potholes. Infact it a part of your car thats constantly being hammered.
Keep them and hope they dont blow out.
Get them changed.
I would be getting them changed.

 

[Blobcat]

Get out and have some "Fun" with them, then get them changed as they'll no doubt be worn out...

 

[DMK/Happy]

Then this must be the life span 60 months or less of tyres on a vehicle that is not garaged, short daily town driving and less than 20K ,really interesting Hope this info helps others.. Thank you for interest.

the old saying you are never to old to learn something new, you good people out there have so much good advice to share on car care may i say thank you, to all of you.

Pirelli P Zero Nero tyre.Think I may source Pirelli all season next, seem to have very good reviews out there.

 

[mioba]

Check the noise rating. On some sizes they can be horrible noisy and hard.
They were aweful on my W220, on my W251 they are awesome

 

[DMK/Happy]

Really important , I like a responsive tyre with as little road noise as possible.

 

[L John]

When I'm driving on a good road the cabin is ultra quiet but on other roads it can be quite noisy.
I've always assumed this is due to the road surface being a rougher texture. There's a very noticeable difference when the road surface suddenly changes.
Concrete roads are the worst but I'm talking about normal tarmac roads.
My question is this, is the tyre partly to blame even though it's great on some roads and noisy on others?
In other words, is the quietest tyre the quietest on all roads compared to a tyre thats rated as louder?
Assuming correct pressures and same tread depth.

I am glad I don't have them any more, too noisy for my liking. Plus the rubber tends to crack too early in their life
