Replace punctured tyre temporarily or both immediately?

[ben_eunos]

Just got a puncture on my right rear tyre. Can't be repaired. There is a delay in getting like for like replacements of about 4 working days.

Would you:

1) get both back tyres replaced today with whatever A brand tyres are available

2) get a cheapo fix replacement for the punctured tyre today and then get them both done next week with same tyres as the front?

Car is a Mazda cx5 AWD. Just got the front tyres replaced a month ago with factory spec Toyo Proxes..

I'm aware it's better to match tyres all round..

Also thought I could maybe get a very cheap tyre today and then order a steel wheel and then get that fitted as a reserve wheel to keep in the shed in case this happens again...

Does your car not have a spare wheel?

Just run the space saver for a few days and dont drive like a nonce.

[ben_eunos]

No space saver. Just has a tube of slime. And it's a big screw stuck in the tyre.

Hence thinking about keeping a spare wheel in the shed.

Second time I've had this dilemma now due to punctures and the delay in getting hold of these exact tyres

Are you dure have you actually checked under the boot carpet.

It does seem strange that you dont havd a spare wheel in a car of that size.

I'd go with whatever they had, and I'd only get one.

Use a tyre inflator before every journey and wait it out or replace it with just and wait for good ones.

Yes I'm not a complete moron. Mazda supply a compressor and a tube of slime.

Had a fortunate result though. Just found a garage which had the exact same brand and model of tyre part worn. Got it fitted for €60 all in. Tread depth similar to the other tyre.

Happy with that!

I always thought the rule was change both in same axle for front wheel drive and rear wheel drive but all 4 on all wheel drive ?

[irc]

Biggest irritation with my wife's Mazda 2 was the lack of a spare. Granted it is used for local journeys mainly but it seems to me there are far more varieties of tyres these days so there is a good chance nobody local wil have a direct replacement in stock. So hence the dilemma for the op.

I thought the whole point of the temporary repair stuff was to use on tyres that do get a nail or screw in them? No good if you have a torn wall or blow out of course. It does write the tyre off though. I'd have no qualms about a tyre that has had a proper repair, the repair plug can't come out, or was it a runflat?

I think the problem with big differences in tread causing issues (diff 'wind up' I believe?) is on cars that permanent 4wd. Is a CX5 selectable between 2wd and 4wd?

[Ussrcossack]

Progress it certainly isnt

[ben_eunos]

Yeah I don't fancy driving around with a big screw stuck right in the wheel. Just screamed blowout to me.

I'm gonna order a Mazda space saver - they are available just not provided as standard.

Re 4wd - i understand the cx5 is fwd most of the time but switches on the rears when necessary. A cursory glance of Google seems to suggest there's a margin of tolerance for tread depth differences across the tyres with it.

I would hope it's not problematic given that the part worn tyre looked a close match to the other.

You would be utterly amazed what abuse tyres will take before they blowout, a screw in it for a few days pales in comparison to what some withstand.

It was letting a lot of air out though and I need to go on the motorway tomorrow. Not gonna risk it unless absolutely essential

Only if there is no central diff, or the central diff is locked.

On a CX5? No danger of wind up.
