I am about ready to give up and go to the tire place but here goes - I purchased 2 new 4.80 x 8 tubless tires for my BCS 715. The tires that were on there had dry rotted pretty bad and I knew they had to be replaced when I purchased the 715. I could not find anyone locally that carred the aggresive tractor tire tread on this size tire so I ordered two 4.80 x 8 Carlisle Power Trac Lug Tiller Tires. I got them late yesterday afternoon via UPS. I took the right side wheel off and the old tire came off without much difficulty. I do have 3 small pry bars which help. Now once I started to put the new tire on the rim the fun started. I used liquid diswash soap for lubricant but I could not get the new tire on the rim no matter how hard I tried. I do not want to mess up the rim or the new tire. Is this something I should just go to a tire place and pay for them to install or are there some tricks on installing tubless tires I need to know? I am fairly mechanically inclined but this is frustrating.
