Donut Size on S-10

[Greg]

When I had my son's truck on the lift at the muffler shop today (didn't buy yet) the guy was surprised that the spare tire donut was a 16" wheel while the truck (standard 2wd S-10) has 15" wheels.  I didn't measure the overall size of the donut, but I assume the donut has a lower profile and would have a larger wheel.  Does everyone else have 16" donut wheels or did GM stick the wrong one under our truck?

Greg, my 2wd S10 has the full sized spare option, so I have a 15 inch spare with a stock full size 205/75/R15 tire, the wheel is just the stock steel wheel rather than the aluminum wheels that come standard with an LS S10.  I have since moved my tire size up to 225/70/R15, but I just will keep the stock tire size for the spare for now.

I also want to ask, what kind of exhaust work are you thinking about having done, are you going to run duals on his truck?  What kinds of exhaust systems are you looking at?  I would be interested if you do buy an aftermarket exhaust for the S10 what kinds of improvements can be made.  I wonder how the sound will be, I do not want to make my 4.3 S10 sound "ricey" or something, I'd like to be heard a little more with a nice deep tone, but nothing obnoxious, I'd also be interested in any mpg gains with an aftermarket, have you found anything out about this on the 4.3?  Thanks, I did not say this in my last message, but putting a 16 inch rim for the spare has to be a mistake, it just seems wrong...

See my other thread about exhaust details - but I'm probably going with a FM40 Delta Flow.  I'm not sure whether it will be single or dual yet.
