Lifespan rating on tyres

aidanki

if I look at tyres given the maze of numbers that is on them is there anything that gives any indicator of lifespan

I know there is a number that gives load at a given speed as demonstrated here http://www.etyres.co.uk/glossary-tyre-terms?term=load-rating

but nothing that gives an indicator of lifespan

Depends on your driving, braking, tyre pressure, how many miles you do, etc...

There is a date of manufactur on them. They say you shouldn't go over 6 years

Too many variables to contend with.

Look at reviews and see what people are saying. You'll find out pretty quick what the average lifespan is.

There's a thing called treadware rating on a tyre that gives an indication of long a tyre should last for.

http://www.safercar.gov/Vehicle+Shoppers/Tires/Tires+Rating#wear

The treadware value is relative to a control tyre from the same manufacturer. Manufacturers will all use their own different control tyres.

E.g. Manufacturer A tyre with treadware rating 140 will last longer than a manufacturer A tyre with rating 120. But a manufacturer B tyre with rating 220 may have the exact same lifespan as a manufacturer A tyre 140.

When it comes to tyres its either grip or long-life, not both.

Tyre manufacturers try their best to find a happy medium but this can only happen with high quality rubber, but high quality rubber costs. Tyres have to mould to the shape of the road to get a grip, grippy tyres tend to have a shorter life. Long-life tyres tend to have poorer grip (therefore longer breaking distances).

My advice: if you are on the market to change your tyres and if you value your safety and breaking distances, buy new or part-worn premium tyres. Do not be tempted with cheap sh1te

like those eco-tyres that are suppose to increase your economy (mpg) but have very poor grip

Fitted 4 Michelin energy savers a while back which were on special offer along with fuel vouchers.Part of my worry was that they would have no grip. So far so good, found they have good grip. I can't state what they are like when throwing them into corners, but for normal driving in a vw golf, they are fine. And I have to deal with all sorts of roads here in Donegal, along with the constant oil spills. God I don't think any other part of the Country has as many oil spills. So much for the EPA.

Grip ; Longevity ; low cost.

Pick two.

Best summer tires I had so far were Michelin Pilot Primacy. Expensive, but I got 22k miles from them and they were within about 3% of the absolute dry grip level of Goodyear F1 GSD3s. Currently I have Goodyear Vector 4-Seasons and they're about the same grip level as the Michelins in the dry and well better in the cool and wet, but the longevity remains to be seen.

It is perfectly possible to get a good to very good grip tyre that has very good to excellent longevity - but you'll pay for it.

They say...or is it the law? Would it fail the NCT?

NCT will let you know tyres are over 6 years old, it's not a fail.

I have tyres over 6 years and no bother. Was yapping to a tyre guy and he had stock older than that.

This website shows the treadwear ratings for tyres.

Remember, these ratings are only good for comparing tyres from the same manufacturer. By filtering on just the manufacturer, you'll get an indication of where they lie within the manufacturers range.

I also had Michelin energy savers on a renault grand megane and they lasted 63k kms. So I got a new set last week, but unfortunately no special offer - €110 ea.

Grip seems to be fine for "normal" driving.

you can find treadware ( 150, 250 , 450 etc ) on the tyre
