here's an older thread on this topic with a short list of mehbe things 2 do...
a nice coat or 2 of synthetic sealant and goop for all the rubber parts would be useful...
consider tire screens from the sun.
1 thing NOT on my older list is attention to the SURROUNDING area...
when the wind kicks up it would be nice to NOT have, ant mounds, loose debris or standing trees TOO near the stream.
