7mm worn and new tyre across an axle...would you?
Discussion
hi folks
Wife's Ionic picked up a huge nail in the shouldher of a front tyre at the weekend. Both fronts were new in december last year, Goodyear Efficient Grip 2's. She does predominently local miles with the odd long distance client visit thrown in.
A new tyre is approx 8mm? These have both worn evenly to 7mm. Would you:-
A. Buy 1 don’t worry about it
B. Buy 2 and try to get some cash back for the other as a part worn
Am i just being paranoid about such a small difference?

I know punctures are few and far between (although some people seem to like driving through nail factories), but when I had this, I got both tyres changed but kept the good one 'just in case'. The good one had 8k miles on it but still a decent tread.
As long as you keep the same brand / make of tyre, 1mm wear wouldn't bother me!

FWIW I had to replace a tyre on my Volvo that was quite a bit more worn than that - probably 3 or 4mm gone - and the chap at the (very reputable) local tyre place said he'd not worry about it for a second. All those tyres that were on it at the time are now long gone and the car has suffered no ill effects.
The only significant point here is about your differential. Where unmatched tyres are fitted on the same driven axle the diff will be constantly turning to balance out the difference. (This can be any axle in some 4WD installations.)
With an "open" diff this is usually immaterial. But if you have an LSD it may be constantly "working" which can lead to heat and accelerated wear.

We have a lot of roundabouts round here and it's renowned for causing uneven tyre wear.Gassing Station | Suspension, Brakes & Tyres | Top of Page | What's New | My Stuff
