Moving up from 245s to 265s, should I change the spare tire too?

In the market for new tires and I was going to go up to 265s since I have no lift, but a thought popped in my head that if I ever get a flat tire and my spare tire is 245, will that damage my differential while I limp to the nearest mechanic shop? From what I got from the inner door code, I have the 4.10 gear ration, non-limited slip. And do you recommend any tires? I am mostly on road but will go off-road a few times for fun and to unload my dirt bike. Currently looking at Goodyear Wrangler Duratrac

Thank you

No problem, even on a 4x4 in 4WD

Differentials are setup to allow one wheel to spin faster than the other, so you can go around corners, outside wheel needs to spin faster than inside wheel

So no limping in, lol, drive it as long as you need to

The limited slip allows that as well, these use gears or clutches that will transfer more power to the slower spinning wheel, but thats all that happens, normal use

A Locking differential doesn't allow it, which is why they are deactivated for street use and then activated only when going straight off road or on a drag strip :)

You shouldn't use 2 smaller tires on the front or back axle of a 4x4 in 4WD, but one smaller tire on any corner will not hurt anything because the differential compensates for that

When picking a tire tread especially off road think NOISE
To get better traction on loose ground you need wider gaps in the treads
When driving on the highway AIR is in those gaps, and when tire flattens out when its in contact with the road that AIR has to escape, and that makes NOISE
Steady HUMMMM at speed, can be down right irritating
So ask around as you are doing

If you want to save some money and get a really good performing AT tire I'd look at the Falken Wildpeak at3w's.

I put them on a year ago and they have performed very well on many off road trips (Mojave Road, Death Valley(Mengel Pass, Lippencott road, Steel Pass Road/Dedeckera Canyon). I don't notice any significant road noise when driving on the freeway. However, I do tend to have my music on pretty loud.
