i have a 2003 blazer that has xtreme package and been lowered but idk how much and if that has any effect and i am looking for rims just stock rims will any blazer or jimmy or s10 rims fit is the backspace all the same does it have to b same year or close to mine been asking round the shops in my town and nobody will help any help would appreciate been looking online and find conflicting info thank you can post pick if need to see blazer

 

Off the top of my head, for at least the 2nd gen Blazers, the back-spacing for the 2wd and 4wd Blazers is different. The backspacing values could be the same for the 1st gen Blazers as the 2nd gen but I'm not sure. If you look up replacement Blazer rims online, look for the year and if it is for 2wd or 4wd.

 

Thanks for the reply I've looked most I see says like 95-05 but people still say some work some don't already bought set and they fit but rub sway bar and was told they for blazer maybe they came off 4x4 but don't say it but thanks for info

 

If you check out tirerack.com and search their wheels, they will allow you to search by 4wd and 2wd.

For 2wd, the stock offset for the stock 15x7 rims is -6mm whereas for the 4wd the stock offset for the stock 15x7 rims is +50mm.

This confirms that the 2wd (which I think includes the Extreme) has an offset of -6mm whereas the 4wd has an offset of +50mm

Here is a link that defines offset and backspacing. https://www.motortrend.com/how-to/06...l-backspacing/
