What to do with mis-matched tyre depth

[ChickenWire]

Hi All!

Hoping for some Pistonheads advice here. I came back to the LGW long-stay car park yesterday to find that I had a flat rear tyre. First flat I've had in 10 years! Managed to get enough air in to drive to a local tyre fitting centre - many thanks to Tubbys Tyres in Crawley for staying open to help me - would highly recommend, lovely bunch of guys! Only 1 tyre available in stock in the size I needed.

So, now the car has 1 brand new Uniroyal Rainsport 5 on the rear off-side, and one 5mm Nexen on the rear near-side.

Fronts are both brand new Michelin Latitudes, which I only just had done. Annoying as I was planning on getting both rears done at some point anyway.

Is the general recommendation to also change the Nexen to the same Uniroyal, or shall I just run it as it is? Seems to drive fine if that means anything! I suppose I could change both rears as a pair as planned to Michelins, and keep both the Nexen and the Uniroyal as spares. Car is a Cayenne 958 3.0d.

Thanks all!

It'll be fine. In a more skitish car, or if the other tyre was more worn, I'd say buy another.

I would. Have you got a spare wheel?

No spare wheel, just a bottle of sealant and an inflator. Thankfully the old tyre held air!

This was my feeling as well, I can’t imagine that it’ll cause any major mechanical issues given that the tyre on the other side is in good nick. If it the other side was close to needing changing I agree, it would have been worth just doing.

I'd be concerned about mismatched tread depths upsetting 4wd system. On bmw xdrive cats, it lunches the transfer box

You will die a horrible death from not having matched tyres all round.
but seriously a 5 mm tyre is only a bit worn, it should be fine.
