I have been looking at going to a little wider tire on my 2500HD. I
currently have 265s on a 6.5 stock rim and its ok for most things, but there
are a couple place I go where it is just barely enough tire. I am looking
at 285 75 16 as the next step up in a decent all terrain radial. I am not
necessarily shopping for the cheapest deal, but I neither need nor want to
"pimp my ride" either.
Most of the 285 75 16 tires I have looked at show an 8 or 8.5 inch rim width
as optimal giving me close to 11.5" of width on the "road" or in the dirt.
I found a bunch of rims that are affordable with a 4.5 inch backset. One
local tire dealer told me that I really should have a 5" backset, and then
proceeded to tell me there aren't many made like that. Well, so far I
haven't found any. Just lots of 4.5 backsets and many at a reasonable
Then I got the "bright idea" to look at spacers. All of the spacers I have
looked at are made from 6061 aluminum billet (probably mill rolled sheet
really). 6061 is pretty tough stuff, but it can still flex and compress
I guess I have some questions.
1. Do I need a 5" backset or will a 4.5" backset clear ok.
2. Are there any reasonable price rims available in a 16x8 8 hole Chevy
3. What kind of problems am I likely to run into if I run 4.5s with a .5
