I have a 1999 Blazer 4dr 4wd stock rims, and I was wondering what I need in regards to information (offset, size, etc) to find rims for it that will fit on without any problems. I know I will need new tires (thats a given) but what should i look for when I'm looking for new rims. I don't want the speedometer to be wacky. I'm basically looking for larger rims which means lower profile tires. Correct? Any help would be appreciated. Currently, my tires are P235/70R15 M+S on both front and back. Thanks guys

 

Almost a month. Any help?

 

Late model Camaro 245 x 55 x 18 that are Z rated! On my 2002 2wd they needed 2.24in adapters. On a 4wd the offset would be about right but the bolt pattern is very slightly different. ( about 0.030).

 

You need to match the overall diameter for your speedo to be correct without tuning.


You can google tire size calculator to compare sizes, or do the math.


Your current tires are 235mm*.7*2+15" = 27.95" diameter. So you need to find a combo that will give you that overall diameter.


Stock 4x4 wheels are 15x7 with 6" backspacing. 5x4.75" Bolt pattern. To have the least chance of any problems you need to stay as close to those numbers as possible.
