RPO codes and door sticker don't match up - tire size
I just went out to my truck and took pictures of my RPO code sticker inside the glove box and the door sticker inside the driver's door. I saved them to computer for my own record keeping and then found a 188-page document that translates all GM RPO codes. I found a discrepancy between mine. There are four RPO codes on my truck that all say my truck came with 235/65-16 tires. My OE tires were replaced long ago but I want to say they were 245/65-16s. I just replaced the spare this past December and I do remember that being a 235. The odd thing is, the sticker inside the driver's door (that also recommends the air pressure) says right on it "245/65-16". So, why the difference between the RPO codes and the door sticker? Which one is correct and is it common for them be different?Clint (TX) 2001 Silverado LS 4.8L auto 2wd ECSB [GARAGE]

So what was the RPO you found on the glove box sticker?
Maybe one of the free VIN sites would answer the question.Ray

For tires to be different than the RPO code isnt uncommon.
Take a look at most Texas Edition trucks, the RPO code for the tires rarely matchs since a lot of regional package changes are done after the fact at a regional prep center prior to dealer delivery.
Look at the Arlington truck plant sometime, they dont produce Texas Edition trucks, they leave the factory with tires sized to a specific factory package then if its part of a regional package the tires and wheels might be changed.

The dealer may have switched them. It happens all the time. Maybe someone wanted the brand of tires that your truck had on it.

I don't know what GM wants the contractor to do when the tires are changed as part of an after market package. I suspect, the 3rd party contractor would be expected to update the door sticker with the correct tire info. In this case, it probably would not match the RPO code.
And perhaps, when this happens the dealer updates the door sticker with the correct tire info.
