Im having trouble with my UST setup. I'm using new Maxxis Crossmark LUST tyres on 8 month old Mavic Crossmax ST UST rims - these have to date been used with tubes only. I followed the instructions as per mavic re soapy water etc. The front wheel hissed a bit from the valve but now seems fine but the rear wheel is leaking large amounts of air from around the spokes. The tyre bead itself is sealed.
I did notice the inside of the valve hole was slightly roughened so is this a case of the valve not sealing properly in the rim or is the rim itself defective?
Will using a sealant solve this problem?

first make sure the valve/hole is not causing the issue.
most likley to have damaged the hole when running the tubes."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Thnaks Nick - can I smooth the hole off - ie lightly sand it or similar?0

probably could but be careful not to remove too much material. i would try some sealant first and see how you get on, i would recommend stans sealant any way as it will prevent punctures.0

Update - started again and smoothed/cleaned valve hole with soapy water a brush and a rough cloth. Currently sealed and working. Thanks for advice.0
