I was looking on the drivers door for the sticker because I was gonna see what the stock tires were on my blazer and there is no sticker. The tire size now on my blazer is 225/75R/15 and someone is givin me 235/75R/15, I was gonna throw them on because I am sure they will fit, but I don't know how far my speedometer will be off since I don't know what the stock tire size was, if it was 215/75R15 then 225/75R/15 are already oversized and if I put 235/75R15 it could be as much as 5-7 mph difference. How would I go about finding what the stock tire size was?

Do you have the owner's manual? It should be in there.

 

I will go have a look, I think the manual is buried somewhere in the glove box. Does this mean that since there is no sticker on the door that it was wrecked at some point in time and it just has another door on it?

 

Not sure. The sticker may be in a different place on you truck. I remember seeing them in odd places on some vehicles. Could be under your hood.

 

ok thanks, looking through the manual now to see if I can find it, and will look around on the vehicle

Well nothing in the manual, it just refers to the sticker on the drivers door above the latch, will have to take a look under the hood and stuff to see if I can find it

 

The stock size for almost all S10 Blazers is 23575R15. You will have no problems at all.

 

Not really. It depends on what year it is and if it is 2WD or 4WD. Nvidia78, please put your vehicle info into your signature, so we can help you easier.

 

hmmm... I pulled a 235/70r15 stock spare off of a 4wd '98. That wont really help, but hell there's one more tire size to throw at you to make things that much harder...

 

235/70R15 and 235/75R15 were both offered. Check the RPO code list in your glove box. It will have a code for the stock tire size.

 

ok thanks, I will have a look there, what code will I be looking for for the tire code?
