Yeah but I didn't really get how the performance of the tyre drops off as they get lower. I am probably a dunce but I found the information useful so thought someone else might. It wasn't directed at you.Sounds more like it's for your paranoia - I already know that and had told you as long as they are 3mm or more then not to worry
Tread Depth
- Thread starter nlel1975
- Start date
Fair enough and they do point that out in the information I posted above.
I have noticed my rear tyres are worn a touch more on the outer tread than the centre or inner treads. The front tyres are pretty much the same across outer, centre and inner treads. I guess this is due to my car being a rear engined RWD car.
Anyway I’m using those readings as the ones I’m going by i.e. Rear Left 6.30mm Rear Right 6.68mm. Going forward when I next check them in a year or so I’ll know to check the outer treads first.
On another note I took the opportunity to measure my neighbors BMWs tread depth as he was parked next to me. I got a reading of 4.70mm from the front left tyre. Checked the production date on the tyre and it was 2618. Twenty sixth week of 2018.

The difference is not an excessive amount.
Found this old thread on when to replace tyres based on age.

As mine still have over 6mm of tread depth and are just over 5 years old since date of manufacture, they are likely to still have a very decent amount of tread depth in a further 5 years based on the low mileage I do.
The recommendation by the manufacturers is to replace all tyres at 10 years of age regardless of tread depth. So I shall be doing this in latter half of 2028 if not sooner.
My tyres were manufactured in 48/18 52/18 and 01/19, so should be replaced by last week of November 2028 when they are 10 years old.

My car is parked in an underground car park and is driven once a week for 23 miles. So not exposed to the elements. On my old car which was first registered in November 2007, I was advised to replace the original Continentals in May 2017 when my car was in the tyre fitters for a reason that I can’t remember.
They ended up fitting some Chinese tyres which I wasn’t happy about but they caught me off guard. Now I know what tyres I want Michelin Primacy 4 and I will ask for those when the time comes unless the Michelin Primacy 5 are out by then.
I have even got some quotes of £387 to £397 for a set of four fitted which isn’t bad by all accounts. That’s probably because they are in a smallish size.

Smarts don't come with spares, not enough boot space!
I guess my usage case are a classic example which should last for 10 years but should be replaced at the 10 year mark as a precaution.
That’s not very helpful. I don’t drive because I need to, I drive because I want to. There’s a difference. It doesn’t cost me much to run the car either. I don’t need to drive the 23 miles each week, I’m not going anywhere in particular. I do it to keep the car running.
Never have to drive on sand.
Can’t see what you’re seeing, must be dirt.
I can’t rotate mine even if I wanted too. The fronts are 165/65R15 and the rears are 185/60R15. Not that I’d need to as there’s only about 0.5mm difference in wear between the fronts and the rears. The car is RWD so extra rear wear is expected. They’ve all got over 6mm tread depth so I don’t even have a need to rotate.
