Disco 2 Spare Tyre Usage

Morning All

I've got a slow leak on one of my front tyres and I think it's close to the shoulder so I'll need a new tyre.

I've got a brand new spare (same make and size) on the back, but the front tyres are fairly worn in comparison so should I avoid just replacing one of the front tyres with a single brand new one and replace both of them with new ones?

If your spare is young, then I'd get another same make and have them both on the front, and get a partworn for the spare - literally anything legal, decent, and not too old - if it is any serious age, then I'd fit a new pair to the front and be done with it ...

Sorry for your wallet

Maybe the time is right to renew all my tyres as I've been considering reducing the size from 245/75 down to 235/70 for a few months and just been putting it off.

Slow leaks are usually simply due to corrosion on the wheel ,had this loads of times on Discos. I which case get the tyre dealer to take the tyre off clean the wheel off and replace it.
TBH my bloke does it for me for nothing cos he gets so much business form me. So, as a stop gap, you could change all the tyres around putting the best two on the front, the next best two on the back and the worst becoming your spare.

I'll pop to the tyre shop tomorrow and see what they've got in stock while they've giving the wheel a once-over.
If they do have 5 new AT tyres in the correct size and the right price I think I'll just replace them all and then sell the brand new spare locally.

Best of luck!

Alloys also can go porous, and leak air through the casting. Only option there is a re-powder coat. Had to do that on my Rav4.

I had an unused spare for 18 years on a car I own, when I had to use it or went bang shedding the tread within 60 miles and I was just 70 miles from home, there’s a usability date given by the manufacturer so so check the tyre production date.

Tis true, which is why in Frogland no one can flog you a tyre older than 5 years.

It's only about 3 years old and it's had a cover on for most of those years.

Should be absolutely fine then!

I'm more worried about the circumference being different between the new and part worn tyres that made me ask the original question as I don't know if it'll cause issues with the diff.
Normally when I've changed tyres previously it's been all five at the same time and this is the first time I've ever needed to change just one.

The only tyres that need to have more or less the same diameters on would be the ones on the same axle. Tyre wear cannot be that critical between axles, I'd'a thort. But doubtless I'll get screamed at for that.
If you are well wedged up and don't mind buying 4 or even 5 new tyres at once then go for it, but I'd still keep the best of the old ones for a spare, especially as you look after it and keep it covered.

Had it nearly three years. Bought from my brother for £300. All its cost me is £320 for some tyres, £50 for an alloy refurb, pads, air filter and oil. Never gone wrong, unlike my Disco. Its currently sat in my field, being used to tow a chain harrow...

I can't do that unfortunately because the new tyres would be a different size.

OK
Well the best of luck then and I'm sure someone will buy the part worns off you.
