Why'd ya pump your tires all the way up to 20psi. I normally run 25#s in
mine just to keep me from bouncing off the roof and have gone lower out of
inatention and/or comfort, at times. The big problem with running non
tubeless rims is in the case of a puncture as the tire could separate from
the rim when the pressure got low enough. That could turn a dicey situation
into an interesting ride for the average driver. I've blown a rear tire at
over a 100mph and it gets your attention.
When I said low pressure, I meant LOOOW pressure like 10psi. At 20 psi it
would take a whole lot of deformation of the tire to get the bead to pop
loose. The guy that rolled the tire off his non tubeless rims with normal
pressure had one of those decambered, lowered, wide tired, wide rimmed set
ups that could probably generate 1G cornering loads. A whole lot of force
on that tire as he had the car loaded with four guys and was trying to do
donuts in a parking lot.
I wouldn't be overly worried running non tubeless rims, just be aware that
low tire pressure/slow leaks/etc. could make things dicey. I'm just amazed
that the tire shops are worried about the width of the rims or putting tubes
in, not the fact that they are non tubeless rims. Seems there is a whole
lot more liability if the typical ambulance chaser got hold of that than the
size question.
