I"m new to all the adding and fixing up on these things did a search for wheel spacers and seen several mention its stress on the bearings.

I’m not into the high performance world of ATVs its at 450 that will be used for yard work, getting the GF back to the trailer at the track and Hunting. Doubt I’ll ever run it over 30 mph 99% of the time.
I understand its will add some stress but are we talking a right good while before you start to see issues or is this something that is going to be quick.
Ordered fender flairs and thought moving those tires out 1.5 inchs would make a lot of difference in being stable. ?
Doubt I will will change the tires for a right good while.
Rather ask on here, I can see you guys know your stuff.
