How tall do those measure mounted?
Overall height before mounting on the Cub were right at 27" - although I never checked the air pressure. I had the local Goodyear guy mount them for me for $15. I'd guess the air pressure would be approx 15psi
Do I put fluid inside them? I think I'll just stack a few weights on these. Here is a template of the wheel weights I designed. These are 7 gage I think, they weighed in at 2 pounds each
