245/70R17 to 255/75 R17??

If I put 17" stock wheels from a 2015 Wrangler (255/75R17) on a 2012 Grand Cherokee (presently has stock 245/70 R17 with 40k miles) -
Will they stick out more or less and what will this do as far as extra strain on my tranny, etc.?

Wheels are take offs, 5 for $400 with only 600 miles on them.

Thanks

Frank

Welcome to CF!

The difference in width shouldn't matter much (10mm) but the diameter and wheel back-spacing might. You'll have to do the math on that and check your stock back-spacing compared to the Wrangler wheels.

From what I can find, the diameter is about an inch bigger on the Wranglers than on the GC.

Wranglers have an offset of 56 mm??? The GC offset is 44mm???
