how much would the ultra rogue wheels stick out compared to the normal stock wheels on my 4 door 2 wheel drive blazer?

 

Ok, so would offset -19 stick out more than stock LT rims?

 

Kind of unrelating, but would 31"-10.5 15" not look right with 4.5" backspacing on a 2000 2 door? or is 9.5 like the max for that backspacing??

 

Your 2wd rims have 0 offset. -19mm would cause the wheels to be positioned outwards19mm further than normal. The exact amount they stick out would depend on the width of the wheels. If it's a 7" wheel like stock, then the -19 wheels would stick out exactly 19mm (3/4") further but if it's a wider wheel, say 8" or 9", then the extra width will also cause the wheels to stick out more. With 8", the total wheel is one inch wider which equates to half an inch per side. 1/2" plus the 3/4" from the offset would put you at 1.25" further out. 9" wide wheel would stick out 1.75" further.

Hope that's not too confusing

 

Thanks! the wheels i was looking at are 8", so they would stick out 1.25" further... Would that cause rubbing using the reccomended 235/70-15 tires? i'm also thinking about evening out the front and rear wheels, so that they are equal when looking front to back (or vice versa)...

 

Hey guys, I have a 2000 4x4 4dr s10 blazer. Ive been looking to put new wheels on my blazer. I already have new 31x10.50 bfgs. I looked up the bolt pattern but I'm a little confused about backspace so I was wondering if these would work or if I need assorted for them to work, Thanks. http://www.4wheelparts.com/Wheels/15...pn=PCW152-5861

 

You shouldn't have any problems with rubbing especially with that tire size. I would recommend leaving the rear wheels as they are, I don't really notice the front to rear difference unless I'm specifically looking for it. If you do want to even them out though, I'd recommend using hub-centric wheel spacers rather than different spec, staggered wheels. Spacers would allow you to get all 4 wheels the same and make it easier to rotate your tires at oil changes.

Do you have any sort of lift? Without a lift, you might run into problems with those tires on your stock wheels. With lower-backspaced wheels like the procomps in your link, the tires will stick out further and more than likely, rub your fenders.

The stock wheels have 6" backspacing and your link lists them at 3.75". That would cause your wheels/tires to stick out an extra 2.25". They're also 8" wide instead of 7" so they'll sit out 3.25" further than normal

here is some info about offset/backspacing Tech Knowledgebase - Wheel Backspacing and Offset

 

Ya i have 2in body lift on it and so i need 15x7 with less backspacing or do i just need spacers?

 

You'd actually need higher backspacing.

Here are the same wheels (link below) except 15x7 and they have 4.5" backspacing which would fit much better than the wheels in your previous link. Basically, the lower the backspacing, the further out the wheels will be. The stock factory wheels on the 4WD models have 6" backspacing

Don't use spacers at all, they push the wheels even further out which is already a big problem with these trucks.

As an example, here's a picture of my truck with 31x10.5 tires. The wheels are 15x7 with 4" backspacing so they sit out 2" further than stock.

 

Ok thanks for all the help!!!
