I'm thinking about upgrading my wheels and tires to 16 inch. Current tires 225 75 R15 are approximately 4.5 inches apart. The new wheel and tire combo would be approximately one inch taller. So now it will be approximately 2-2.5 inch gap. Is that enough?

A diameter increase of 1 inch still only places the tires 1 inch closer together (2 x radius increase of 0.5").

So the new tires would change the spacing from 4.5" down to 3.5", which should be ok. This leaves enough room for axle movement.

Your right, thanks! That's even better.
Any ideas on what my tire/wheel combo might be worth? St225/75r15 Castle rock and white spoke wagon wheels.

With 15" rims tire selection is not so good. With 16" rims he can get away from cheep china tires and get some good LT tires if he chooses .

Who'd a thunk.
One of them facts that aren't obvious until you look into it.

Did the same thing on my 5er, if you now have 4" this will give 3.5". Plenty enough.

You will be fine. I upgraded my 16" tires to 285 LTs and I have about 1.5 space with no issues to date.

Sure, as long as they aren't rubbing!

Upgrading to larger tires. Space between tires question?
