My old conti gravity UST's could be inflated without sealent on mavic en321 rims with (not quite, but cheepo DIY) stans strips with a mini pump and no sealent!
How come my new non UST conti's just wont go up even with a track pump!
New combination:
DT 4.2 rim
Conti explorer with snakeskin sidewalls, steel bead, non UST.
I've tried……….
Gheto with just a valve and electrical tape – no joy
Ghetto with just valve, electrical tape and washing up liquid – no joy
Ghetto with bmx tube, split and hanging off the rim, tyre over the top, washing up liquid and some water to get it foaming – no joy
Ghetto stans strip (cut the innertube down to fit the rim well) and washing up liquid – no joy
What haven't I tried? Got a huge stock of nearly new normal tyres so don't want to buy more UST ones.
And don't want to start wasting expensive sealent untill I've at least managed to seat it on the rim temporerily.
Time to bite the bullet and buy a compressor? How many litres does the tank need to be, and how big a motor would I need to do some light shot blasting (its other likely job).
