Someone running Indy 144s with 3 washers in the inside and got a caliper to measure the width?
Or just measuring the width of 2 speedrings would work too i think! Trying to figure out if i really need a set of 149 on my 8.5" and how much diffrence it is between a 149 and a spaced out 144.
I haven't seen many / any posts about the three speed rings (washers) but I have been doing that for a while, especially on new trucks, which brings the wheels out as far as possible and have the wheel nut just snug right on the end.
As you asked, I use 149s and the three speed rings with bigger wider wheels which sit flush with the 8.5 decks I ride and it works perfectly for me, but a lot of people don't want to see their wheels or like them sitting inside the deck, so although it would sit inside a bit, you could get away with doing that with 144s.
The other thing is whether or not you want a little more truck grinding room, or prefer a wider feel or a not so wide feel.
It is about 5 mm in total difference, so about 2.5 mm each side.
What size or shape wheel do you ride?
