Maxxis Minnions , tubeless ,are they ok ? , ive never had tubeless tyres on a bike , are there any major drawbacks ?

None..
run them around 20...24 psi..front and a couple of psi more at the back..
you may need to adjust pressures to suit your weight but after a bit of trial and error you will find the sweet spot.
you may have some fun and games sealing them ,inflating first time..but you wont regret doing this..
enjoy
Just embarking on this myself. Have got a Stans Notubes standard kit but told I need only valves, tape and fluid if my rims are welded. So may be sending it back.
Only thing worrying me is low pressures being too squishy on tarmac sections.
Am running 40psi at the moment.
Have come from an old school MTB so still playing with setup.
Don't be too quick in sending that kit back. A welded rim is not an airproof rim. Every spoke hole is a leak. Just abut all rims are welded nowadays.Just embarking on this myself.

the main reason for tubeless is to run low pressure..
reason for this is you wont get pinch flats like you do with a tube.
the low pressure allows the tyre to deform over roots and rocks so you get a lot more feel and grip.
its quite a revalation ...
big volume tyres like continental trail kings ..hans damph minions etc are where you get the most amaizing results..the deflection you have or get with 40psi is not something you will ever want again after a day on low 20's psi trail tyres..
But if you do lots of tarmac? It may be a waste of funds..

You don't need the kit if your rim is a UST-certified rim and there are very, very few of those. UST is a Mavic invention and a standard, if you wish, for certifying that a rim is tubeless without the need for tape and sealant. For a rim to be tubless or UST-certified, it needs some very special engineering that drives the cost up significantly. Firstly, the spokes have to screw into the rim itself. The spoke screw socket has to be welded to the outside of a seamless rim etc etc. This makes the rim, spokes and hub proprietary and expensive.
Tubeless conversion kits are the way to go in my view. They are cost-effective and still leave you with a standard components that any bike shop can fit and repair.
Fitting the kit is not easy though. Expect lots of trial and error and don't attempt it if you don't have a compressor or some other source of bulk cheap air/gas. You could inflate it with CO2 first time if you don't have a compressor but then you can't put the sealant in in the first inflation since the sealant is not compatible with CO2.
I suggest lots of prior research.
Other than installation problems, tubeless is fantastic. For serious MTBers there is no other option.

I know the WTBs well. Nice rims but as you say, not the full monty. The full monty is always some proprietary wheel, you can never buy just the rim itself other than for one Mavic rim I know of. The WTBs will convert nicely. I don't know those tyres at all. The trick with tubeless tyre is to look for a tyre with a thick sidewall and thick juicy beads. The jucy-er the bead, the better the seal. You have to squeeze a couple of different beads before you will grasp the concept of juicy. Super lightweight tyres rarely convert nicely and always leak air. By definition a tubeless tyre will be thick. Have a look at a UST-certified tyre to get an idea of just how much rubber there must be on the tyre before it seals properly.I'm on WTB i23 TCS rims. Tubeless compatible it says but probably not the full monty.
The tyres are Vittorria Barzo folders. Not certified tubeless but Evans mechanic said to try them tubeless anyway.
Yes, there are several drawback.Maxxis Minnions , tubeless ,are they ok ? , ive never had tubeless tyres on a bike , are there any major drawbacks ?
