Putting a new tyre with a part worn set

[DieselRob]

It’s a John Deere on Bridgestone VF710/70r42 at 60% wear, 1 rear tyre has got some damage to the outer skin, inner carcass is undamaged but the tractor carries a lot of weight with a 6m weaving sabre tine so I’m wondering about forking out for a new tyre rather than waiting for the brown trouser moment

Will a brand new tyre go with the 60% set and not cause any gearbox/diff issues. Is there a rule of thumb or science for mis matching tyres

Might lean over abit

I’d not fit one only. But it’s not my lively hood nor my tractor.

Only a tad, it’s 61mm tread depth on a new tyre, 38mm on the original

I’m not inclined to fit 1 only either if I’m honest but we’re talking well over £7k for a pair of rears

Yes a lot of £’s but as far as I can gather this is a full on working machine.
Not like my elderly hobby tractor and I ‘d only ever fit a pair.
Go down the single route and you will always be one step behind, eh

I have been looking but with it being a VF it’s harder to find 1

Is it not suitable for a major repair?

Is it not suitable for a major repair?

It has been said not. Due to the softer material used to create the VF type tyre.

Not much science but there is a little bit of maths.
Your circumference on a new tyre is a bit over 6.15m and the worn one would be 6 or 8 inches less, so the differential will always be working away quietly with mismatched tyres.
Just on these gurt big 710R42 sized ones it is a large/long distance difference per revolution.
An inch per metre of travel is quite a bit if you look at it like that.

As above if I could, would put 2 new rears on and keep those for spares/sale, although it may be able to be repaired if it's only a matter of vulcanising some new rubber in there to prevent it getting worse. The belts do the work but they do need protected by some rubber.

Just buy one new one and pump the other one up harder

You need to look at loaded rolling circumferenc, you might be surprised.
