ok so i have a 2002 blazer xtreme and on some websites say its a 5x120.65mm 5x4.75 and some other people say its a 5x120.7 5x4.75, some places say that they just round it and it shouldent make a difference, so i bought rims that are 5x120.7 5x4.75 will they fit??? ive heard lots of things i didnt think that .5 mm would make a big difference, as long as i have the right locks and bolts.....help me please

 

Yes, they will fit. Either 5X4.75 or 5X120.7 are correct. Never heard of 5X120.65, though.

Oh, and it's a .05mm difference which is small enough that it probably wouldn't matter.

 

Exactly.

4.75 [in] * 25.4 [mm/in] = 120.65[mm]

So the ones listing 4.75" (120.7mm) are really the ones rounding off.

0.05 [mm] / 25.4 [mm/in] = 0.002 [in]

And 2 thou is not going to make a difference. Especially when the rims are made to a 4.75" bolt circle and not really to the metric equivalent.

 

2 thou, I would hope they would allow more clearance to mount a rim LOL

 

I was waiting for someone to break out the math conversions...lol
