Just decode them all. It'll show you what your truck was originally equipped with.

 

Hmm.. for wheele/tire RPOs look for:
WHEEL AND TIRE N60 -- N99, P01 -- P99

then use This Magic Decoder Ring to see what you have

Or just use a shrug

** Mad props to swartlkk for posting that gem in 2006** *adequate props to me for linking you to it *

 

ok thanks guys, will decode all that tomorrow, and thanks for the RPO list to check it with

 

Well seems mine was a N90 which is the 15 X 7 aluminum cast 4.75 inch bolt circle, I had nothing for P, really don't tell me what tire size was stock, it has 225/75R15's on now so I am assuming they are correct, and I will be putting 235/75R15's on in the near future.. If I had the cash to pay for the carfax report I am sure it will tell me if it was wrecked, there is like 11 reports on it. No sticker under the hood either

 

Hmm sounds it might have been in a wreck, and the front end and door could have been replaced.

 

maybe you could check your spare tire, ive got a full size spare im not sure if all blazers came with them tho.

 

Yeah I was thinking along the lines of that too, since the door has no evidence of a sticker even being there, I might just get the carfax for it sometime in the next few months and see if it has been wrecked

 

Already checked the spare, not a full sized one, the spare is under the vehicle, have to crank it down with the tire wrench, although I have seen a couple of blazers around here with the tire mounted on the back of the vehicle

 

If it HAS been wrecked get underneath and check your frame. Body panel wrecks aren't all that big a deal, IMO, but definitely look for structural damage.

 

ok will have a look when I go up to my dads for the rest of the week
