i'm guessing you have a 3/4 offset difference, which is a inch and a half when you flip them, which does make a big difference.
Three inches total is huge in the whole picture. Well worth the work of flipping.
my 3320 with r4 i'm guessing is about that same distance, and its night and day from skinny to wide position.
I will try to be clearer.
It is just short of 27" between the sidewalls of the 2 tires on my 2000
4300. It is just short of 28" between the sidewalls of my 2001 4300. Both
have 15" wide R4s, and the latter has the wheels reversed. I would call the
width difference gained by flipping the wheels to be between 3/4" and
1" total. Say 7/8". The last time I measured this, I did it from below, so the
tires may have been a tiny bit bulged out at the bottom, and hence the
3/4" number.
I DO think it is worth flipping them, even for this small gain since the
rear track is very narrow, and I need everything I can get to fit my
backhoes on there. I even trimmed the foot rests of the last one to
clear the tires. R1s would have been much nicer to have.
I have seen the 3x20 tires/wheels at the dealers and shows, and they
look the same. I assume the 4410 uses the same wheels/tires, too.
