I had the LBS install my new Vittoria corsa pro control tires tubeless using Stan's yellow rim tape. I read where Stan's recommends 2 wraps for pressures over 45 psi. These tires have a max pressure of 80 psi and I expect to be riding in the 60-70 psi range. The LBS used one wrap and said that was customary for tubeless tires.

So what's the consensus here? Am I ok with one wrap. Anyone else running one wrap with 70 psi or more? And what's the biggest risk - just slowly loosing pressure or a catastrophic loss of pressure?

Stan’s say two wraps are *required* for pressures over 45psi, so if you’re running over 45psi, I’d definitely wrap it twice. Show the shop the Stan’s site if need be.

I dunno what the biggest risk is, bit why take it at all?

Yes.. two wraps. I even do two wraps on CX or MTB tubeless. You will see why when you take the tire off.
Good idea is to de-burr the spoke holes in the rim before hand.

Start opposite the valve; go 2 times around.

I would go with the recommended.... BUT, if you're going to do it over, anyway, see if you can find some good tape like DT Swiss.

I would suggest finding another LBS. Every instructional video out there, all recommend 2 wraps & for good reason. And unless you are using foam liners & having issues with fit, there should be no reason not to wrap 2X. I could speculate as to why the shop did this but none of the scenarios benefit you.

Two wraps. If it were me I'd get it re-wrapped correctly for sure.


It depends, but the tubeless rim tape covers the spoke holes so if it blows through one of those it'll be a fairly rapid loss in pressure!

I haven't tried DT Swiss tape, but I definitely prefer Muc-Off tape to Stan's.

DT Swiss is more rubbery, stretchy and supple - so much easier to install than Stan's. Zipp uses something similar to the DT Swiss, maybe just rebranded. I wouldn't be surprised if a number of newer generation tapes have similar properties.

Noted for next time I need to buy tubeless tape. My most recent wheel purchase (Ultegra C50s) have hole-less rims - no tape needed!

I use two wraps for my 70 psi road bike and my 45 psi IGH commuter. Better thick than sorry I say.

My first set of tubeless wheels were from DT. No tape needed. Except if you use tubes they included a rim strip for some reason.

if you are referring to little trails of sealant migrating towards spoke holes then I know what you mean. I’ve been experimenting with using a heat gun and a plastic tire lever as aids in smoothing out every last air bubble when installing new tape. It seems that on my 2 road tubeless bikes, I will have great air retention for a while and with no apparent reason that great air retention will become less than stellar. When installing a new tire if I see any questionable spots on the tape I retape.

The bike shop will redo the wheels. I have opted to go with Bontrager rim strips instead of tape.

Protection at the stem hole, maybe?
