The official line is "All tyres have a life span and a date stamp on the sidewall showing the week and the year it was manufactured. So 2206 means the tyre was made in the 22nd week of 2006. You should never use tyres over five years old whether or not the tyre is being used, as the rubber in a tyre degrades over time."

This is particularly relevant to high performance cars / SUVs.

On trailers, caravans, motor homes and older collectors' cars then do not fit new tyres that are already 5 years or older. All road tyres to be removed after 10 years of age regardless.

Gradings on the the tyre sidewall also show values for:
tread wear
traction
temperature


A control tyre is assigned a grade of 100. Other tyres are compared to the control tyre. For example, a tyre grade of 200 should wear twice as long as the control tyre.

Of current tyres:

15% are rated below 200

25% are rated 201 – 300

32% are rated 301 – 400

20% are rated 401 – 500

6% are rated 501 – 600

2% are rated above 600

The treadwear grade is a comparative rating based on the wear rate of the tyre when tested under controlled conditions on a specified government test track. ... As a result in real world driving, it would be incorrect to say that a tyre with a treadwear grade of 200 gets twice the life of the Course Monitoring Tyre.

Enough already I hear you scream! :ugeek:

Like others have noted - I had Pirelli's on my Evoque - they were 20" and I got 30k out of them easily....

At 13k so far I only have a couple of mm left before the markers - I can already feel traction leaving at the rear coming out of junctions.
I may make it to ~17k - most of my driving is between B roads & motorway so did expect more

Thanks for the names in NI for other places to call - will give them a bell and see on price comparison.

Biggest question from me is - do I stay with Pirelli or go with something else - Michelin or other?
Will they handle any better / worse or have better or worse wear....

T, given a free choice I would go with Michelins but they are a fair bit more expensive than Pirellis.

+1. I am very happy with the OE Michelin handling and wet grip on my Macan. :D

T, the thing about trading a car that has less than 3mm left on tyres the dealer, especially Porsche, will simply take the full cost of replacing the tyres off the deal.
I do think you have arrived at the same thinking as me when it comes to the home car fleet. Do you realy need two SUVs and no sports cars? My wife does have the TT but that doesnt realy count as I hardly ever drive it. I wouldnt be without one SUV but if your going to have multiples it is better being sports cars.

Steve, do you work in the tyre industry, or did you copy & paste that lot...? ;)

I worked for 40 years in the tyre trade, but I check my thoughts by referring to online data before posting on this forum. :idea:
