They are 2 inches. I was told at some point 2 inches not sure if its these wheels or another set I have I don't know why I went with 2 at the end.
It sounds like you may be able to do a 1/2 inch with them after research. I had planed on returning them to get something different but once again I got distracted

so I own them now
.02 is what I asked for

Im trying to fight the urge to buy the correct size without knowing the correct size until it sits and drives.
Our comfort tempature range is very similiar while the range being at different points.



Knowing the brand that has given great service alone is way better than me getting lucky with whatever brand I pick

Thank you
