ok this a question about AIR
Ok question is what have you WHO have trailers picked for the right air pressure in the rear tire. This F3 is has only 4000 miles so it has OEM tires and rider will be alone about 165#. Taking load off bike except coats, helmet, rain gear. Still I dont see a heavy hitch weight or trailer over all weight to high.
But any ideas I have 28# now
If you are still running OE spec Kendas on the F3 &/or the trailer, then 28 psi sounds about right! Check your manual &/or the tire placard - they may recommend increasing your F3's rear tire pressure by as much as 2 psi if you are fully loaded or towing. Because of their lightweight construction, the OE spec Kendas NEED that much air in them to carry the loads imposed upon them! Running them at lower pressures won't vary their tendency for rapid wear in the middle of the tread; cos with the Kendas, that's largely due to centrifugal force throwing the middle of the tire outward as it spins/rolls, leaving you running only on the centre few inches, and thereby wearing that strip out rapidly!! And you still NEED that 28 psi in your F3's rear Kenda tire to carry the load imposed upon it or you risk catastrophic tire failure!! :shocked:
However, if you are running a stronger, higher load rated auto tire on your F3, then depending a little upon the actual weight/load on the tire &/or its load rating/construction, running tire pressures in the range of about 16 to about 18-20 psi will likely work a lot better! :ohyea: Anything much more than about 20 psi in most auto tires under the load imposed by even a heavily laden Spyder is likely to be over-inflated & therefor risking accelerated wear, vehicle wear/damage, &/or tire failure as a result! And those same basic pressure rules apply for your trailer!! Regardless of their use/application, the OE spec Kendas will NEED about 28 psi to safely carry the load, but running anything that high in a real auto tire under a lightweight trailer would mean that an auto tire on your trailer is grossly over-inflated & sorta like running the trailer on a railway bogey!! :shocked:
If you go too high with the pressure in either type of tire on your trailer, your trailer tires can't/won't be able to work with the trailer's suspension to keep it easy enough to pull while still allowing the tires to conform over road irregularities and debris etc, absorbing vibrations and road shocks etc, and basically working to avoid destroying themselves, the trailer itself, and/or anything the trailer carries!! And all those shock loads & vibrations won't be doing your hitch &/or tow vehicle much good either!! :lecturef_smilie:
