Different tyre sizes on rear diff

[spynage]

Hi.

Got a flat tyre today. Got the spare on but I see the sizes are a bit different. The car a Nissan navarra D22 has 265,65,17 all round. The spare is 255,60,17.
The tyre size calculator says there's is a 5% difference in circumference. I intend to change it later and I won't be using 4x4 with it. Can I expect any problems with that mismatch on a 200 mile trip?
I believe the car has a limited slip rear diff, but that's just a Google search enquiry. I don't know for sure .

Thanks

Swap the spare to the front and keep it in 2WD, i'm assuming here the front axle isn't permanently driven?

No it's fully selectable. The front has a diff as well. Won't it affect it in the same way?

Does it have free wheel hubs?

No

I'd do this.

A constant wheelspeed difference across an LSD doesn't strike me as a particularly positive exercise in mechanical sympathy.

Unless you've got a limited slip diff, it's nothing to worry about.

Could be a problem if you've got an LSD, or a computer-activated AWD system. I seem to remember that on AWD Volvos, you had to change all 4 tyres at the same time, so a puncture could be very expensive...

Thanks. I resolved the problem. Think I got a new used tyre in the end. Truck is now in ukraine ! Thanks for your responses
