Hello, my name is Ben I'm a newbie here! I have a serviceable tube from my 1993 explorer I will part with for $750 if you are interested let me know I'm in Miami.
Also have a set of seat cushions with the plastic bases for each seat in the early models with the small rear cushions will take $150 for the set of cushions.
The tubes are missing the rubstrake but all grips are well attached and there are no years or rips, the tubes hold air for a little while but will need to be sealed with tube seal or find the pinhole leaks.
The tubes weigh in at about 30lbs if you want them shipped I can put them in a box and ship at your cost.
These tubes are for the early explorer but can be easily adapted to fit newer explorers by adding two flanges with aluminum threaded slats instead of one in the middle to fit newer models.
