One tyre, what would you do?

Basically, had a front tyre replaced recently so one tyre is almost new with 8mm of tread and other front tyre has approx. 4.5 - 5mm so still loads left.

However, I'm contemplating replacing that tyre for a new one. Winter is coming, lots of wet weather etc and it would mean the two fronts are equal and new. Plus I'm a bit ocd with things like that. Or am I being daft?

What would you do?

I’m funny in the same way, only because I want to replace them at the same time.

I would replace the other one, and keep the 4mm as a spare for a future emergency.

The difference in performance on those two tyre tread depths is minimal. I assume that they are the same make and tread pattern.

If winter performance is important to you then go for Winter tyres on a set of steel wheels. The difference between summer and winter tyres in wintry conditions is huge.

There is a you tube video of two cars climbing a snow slope, 2WD with winter tyres and 4WD with summer tyres, the 2WD car trounces the 4WD.

Braking and grip are both significantly better.

If they are on the front,,put the new one on the left hand side the left always wears out quicker than the right side on the fronts.

Never noticed that before, why does it wear out quicker?

The reason being you always go round a roundabout clockwise putting all the weight on the front near side tyre,,I know it might sound stupid but when you’ve done 20-30k with your tyres just check them with a depth gauge & their will be up to 2mm less on the ns tyre compared to the offside.

I've genuinely had nothing other than equal tyre wear on any car.

Most roundabouts are low speed and often involve sweeping to the left on entry, then steering for the roundabout, before again turning left to exit. It's not as much a one sided manoeuvre as it may appear.

I'm like Kerr, never noticed anything other than roughly equal wear on the front, that's in front and rear wheel drives too.

if you would notice the tread difference and how much depends on the car, bmw xdrives seem to have a lot of reported problems and can damage transfer box with just a small difference, your average front wheel drive not so much, i would like most people try to change one axle at a time,

i believe what would wear one side more on the same axel would be torque steer more than anything, so depends how you drive, smooth on the throttle should keep it even, but all so make sure all the geometry is correct 4mm is a big difference if you're a steady driver,

There is no way over the lifetime of a tyre that you would have unequal wear. Unequal wear is the function of something wrong with your car or the tyre.

Unless you drive to work on a banked oval for 10k miles, it’s complete rubbish.
