I know just know enough about wheels to be dangerous.

If I decide to upgrade my 15" steelies when the original treads finally wear out, and I put on the 16" alloys from a SE or NISMO/Pro-4x, what am I to do about my spare?

Can I put a taller tire on it so the roll length will be the same? Would I need to purchase an inexpensive steel wheel of the same size as the new alloys?

Reason I ask is when looking for sets of OEM 16" alloys from 05-current they seem to be sold only in sets of four.

if your truck is 4x4, you should be concerned with having a spare tire the same size as your running tires. you dont need a different rim, just the same size diameter tire.

if you are 2wd, no need to worry about anything.

You can go up or down in wheel size without changing the overall diameter of the wheel/tire combination. It depends on what size tire you buy. Check out these pages at discount tire's website: Tire & Wheel Plus Sizing - Discount Tire and Tire Dimensions Made Simple - Discount Tire

ok thanks! so i see about the plus 1 plus 2 sizing. my stock size with the 15" is 235-75R-15. That's a 28.88" diameter overall. my end goal is to up the tire size a bit though - my speedo is 2 mph too fast.

the stock size on the 16" is 265-75R-16 right? That would be a 31.65" diameter.

So I would need to put a tire on the spare to match that diameter - right?

thanks!!!
