Winter tyre question

[Green Giant]

hi
I need to replace a winter tyre after a puncture, unfortunately tyre shop can’t source the exact same tyre model, (a continental winter contact870, they can get 880 or 860 instead of 870, will this be ok on same axle when in France etc, if I ever got a stop check,
They seem to change the tyre model every year, I remember buying 830 years ago
Not in van, I’m away with the car for a few weeks but in Uk

I believe that it is best practice to replace in at least pairs if not whole sets but if it is only for a short while then I guess it will have to be OK so long as it is very similar and of the same type. Can they not repair the tyre? Its a curse having problems away, finding things and outlets a pain for most people.

Unfortunately can’t be repaired, it’s the same make and type of tyre, just a different number, I’ve had Wintercontact TS 830, 850,860 and 870 all the same size, speed ratings etc, just a very slight tread patten design I remember on one, anyway I’ve ordered the tyre as I need to get back on the road

It will be OK then. I hope that your time in France is not too spoiled with the tyre thing and that everything else runs smoothly and to plan.

The days when we all had spar tyres seems to have gone. It is unfortunate I think, that spare recess was not within the boot area and of sufficient size for outsize wheel tyre combinations and held the tools to do the job. The other way would be for a wheel rack on the rear door and not have to pay up- to £1,000 for a converted bicycle wrack carrier. More of us then might carry a spare tyre. I don't either but perhaps I out to sort a rear door mounted job. A carrier that would electro - hydraulically lift and lower might be the ideal. Their is a job for the entrepreneur.

Also need to be careful with 4 wheel drive that there isn’t a massive difference in wear between the tyres.

You are of course correct in that but perhaps tyres from the same manufacturer are more likely to match up.

It’ll be fine unless the remaining tyre is much more worn than the new one. Or there is a big difference in tread pattern. If it is I’d buy 2 and keep the worn one as a spare.

It is a AWD but hopefully I’ll get away with the 300 mile trip home, I’ve got a brand new tyre in the garage at home so I’ll fit that to match my new one I’m having fitted tomorrow
I’ve got a space saver wheel/tyre in the boot but don’t fancy driving home on that up the M6 unless an absolute emergency

I was thinking more about differing rolling radii (due to wear) and transmission wind up.

It's not just tread wear.

After a period of use the plies in the carcass take on a 'set' and will sit, sag, call it what you will, and flex in a certain way.

It takes little time for a new boot to achieve that state, so in the event of emergency braking or maneuvers the new tyre won't behave in exactly the same manner and you get instability due to those differences in behaviour at the limits of the tyres performance.

This is also why tyres thar have been in use a while should never be rotated to the opposite side of the vehicle where they would turn in the other direction, although modern asymmetric treads rule that out a lot these says.

So unless the remaining tyre is very new, a couple of thousand miles or less, I wouldn't personally mix a new tyre on the same axle except as a spare to get me home, regardless of the remaining tread.

I don't care how much it costs, I always replace tyres in pairs on the axle, or all 4. No matter how poor I get my family's life I worth more than the cost of two tyres.

Yes you are correct in that usually they say change in pairs for that reason and probably in all wheel drive all 4's. the reason why I said same manufacturer was in the past I have use 9.00 x 16 tyres on a LR 101FC and when I replaced the military bar grips for Michelin of the same size but radial the ise difference was absolutely massive. I had also notice slight differences in tyre size between manufactures many years ago but today I have no idea my guess is that regulation and type control are far more strict today and so have better conformity.

Perhaps our friend had better replace both tyres on the same axle, that is 2 tyres. Unless they are all heavily worn that is!
