Hi there and thanks for that info. My l2501hst having the 15x19.5 rear tires measures from the floor to the top of the rops bent is 72 in. My garage height clearance is 79 in. That's why I was asking about the R14 the series tires of which only two are offered on the website for this l3902hst tractor. One of them has 15x19.5 and the other ones have the 43x16.00-20. I would have rather had the wider 43's but somebody said they were taller then the other series, the 8696/7. I'm much rather would have had the 43s because they are wider also then the other option of the 8696/7. Thoughts?
