Hello, I am new to the forum, been snooping around for a while, but this is my first post. I have a 01 blazer 4d 4wd and need to put some new tires on it, and figured while I was at it I would upgrade the wheels as the stockers are getting corroded and causing some leeks. I am looking for some inexpensive steel wheels and came across these by cragar and it looks to me that they are the same size as stock, but I have also read elseware on the forum that cragar does not make wheels that will fit our trucks so I wanted some input from you guys to make sure I am getting the right wheels. They are 15x7, 5x120.7, and 6" offset. Here is the link to the wheels

As a side note, I will be getting 30x9.5-15 Firestone Destination AT tires

Thanks for the help, this forum has already been a huge help answering other questions I have had.

 

An offset of 6 is 6mm, not inches. That would be about a 1/4" additional half the rim width or a total back spacing of 3.75". Without a lift, you will likely rub with that short of a back spacing.

 

If you are not gonna lift the vehicle then stick to a 4.5" to 6" backspacing with 30-9.50 tires on a 7" wide wheel... 5" to 6" bs with an 8" wide wheel.

 

thanks for the replys. So a 4 1/2" backspacing will work with 30x9.5 tires without any rubbing? Also, I found the wheels on the site posted under 01 blazer 2wd, do 2wd blazers have a different offset than the 4wd blazers? I assumed not, that's why I figured the offset of 6 was in, not mm. Any further info would be great, thanks again!

Ok, I found some cragars at summit 15x7, 5x4.75, and a 4.25" backspacing, will these work with a 30x9.5 tire without rubbing?

I am doing a bunch or searching thismorning and realized I may have been a bit confused. Our stock wheels have a backspacing of 6", that would make our stock offset something like +2" or +50mm correct? So when looking for wheels I need to make sure to keep in mind if they advertise the offset or backspacing as they are different. Can someone confirm that this is correct (6" backspacing and +2"/50mm offset are the same thing)?

 

Yes, 2wd S10 wheels have less backspacing than 4wd's.
Look here for more wheel answers... you can search wheels by diameter, width, offset and/or back spacing. I think it will give you a better understanding of the whole +/- mm thing.(which I never go by, I use back spacing measurments)

Thanks for the help! I think I will probably go with one of these from summit. They are stock size except 4 1/2" backspacing. As I said before, I am going to go with 30x9.5 Firestone Destination AT tires (maybe BFG AT). Do you think I will have to trim to make this combo fit?

No, I really think you will be fine with those wheels and 30"s... let us know how it turns out.
