and if its low just fill it up with the on board air hose

Interesting about the DTS spare. My Dad has a 2007 DTS so I will have to check it out and see if it is the same.

And since someone brought it up here... Do the Grand Prix GXP Cross-drilled Rotors fit the 2004-2005 Bonneville GXP? I thought the rotors on the Bonneville are slightly larger in diameter.

And to note, I have 3 stock RSA'* with only 7,200 miles on them and even wear for sale...$50 each or $130 for all three plus shipping.

Yes, turns out the 07 DTS uses the same exact spare. I bought one from a junkyard and its the same 5 spoke rim and tire. Now i have a spare for my Grand Prix!

The GP GXP has 12.7" rotors in the front and 12" in rear. I was told the GP and Bonne GXP use the same PBR calipers and same size rotors, so i'm assuming you could use the cross-drilled rotors from a GP on a Bonne GXP.

Ik this is an old thread but in case anyone is still wondering what type of doughnut spare will fit on a Pontiac GP GXP, i found that the doughnut spare from an 06 Impala SS will fit on both the front and rear. It is only a 16" rim but has enough clearance to fit the rotor and caliper on front or rear. I cracked the alcoa forged aluminum 18" oem front left wheel on my 06 gxp and needed to find a way to get my *** to work while i get it tig welded and remounted. I got the spare doughnut from a friend'* impala not knowing if it would fit but sure enough did. Ended up taking one of the narrower rear wheels and puting it up front and using the doughnut on the rear but the doughnut will work on the front if need be.

Dude even admits its an old thread and still bumps it.

Yes it'* a tad old indeed Mike.
If a thread is older than 6 months please do not bump it, we would rather have you make a new post in the correct section and refer back to the old post with a link.
