changing V2 Aero 150 tires
I have V2 Aero 150 roller skis. One of the tubes just blew and I am
trying to replace it. I have broken one tire lever trying to get the tire off. Any hints / suggestions on this is most easily done? A lot harder than a bike tire ... Thanks! |

changing V2 Aero 150 tires
I just had the same problem yesterday and after an hour of frustration
(trying to get the new tube and tire back on) I swallowed my pride and paid the guy at my local bike shop $2 to do it. I took him about 10 minutes. On the subject of blown tubes...I bought new rollerskis only two months ago and have blown two tubes (a 150 and a 125) already - both with the same problem: a tear at the base of the valve. It seems odd to me that the tubes failed so quickly and in the same way. Has anyone else had this problem? Am I doing something wrong?

changing V2 Aero 150 tires
My 150mm Micro (kickscooter) wheels I bought for a rollerski project must
then be easier that the V's. With some tire levers I get them of, no real problem. I *can* get the tire back on without tools, just standing on the wheel with bare feet. Not really easy though. The Micro wheels are full slicks and cost between ?10-15 in Europe. Just onder 300g for tire+tube+rim. The blown tubes sound like overheating or/or rotation tires relative to the rim. It happens to mountainbikes on extremely steep downhills where the brakes are on max all the time. Did it happen in conjunction with a fast downhill and speedreducer perhaps? Otherwise maybe the rim has rough edges that do their work at high-psi. "Matty" schreef in bericht ups.com...

changing V2 Aero 150 tires
Yeah, it took me a while to figure this out, too.
First, I use old Schwinn steel tire levers, though I think I've used plastic ones as well. Getting the tires off hasn't been as much of a problem as mounting the new ones, however. I have three tips for that: First, I heat the tires in the oven as low as it will go, about 170F. Second, I spray the wheel, tube, and tire with silicone lubricant. Third, and most importantly, I clamp a Phillips screwdriver with a shaft that the wheel axle bearings will slide over in a vise, pointing up, and mount the tire and tube with my hands only with the wheel on the shaft. This allows a lot more force to be applied with my hand, like bracing a bicycle wheel axle against the edge of the workbench when mounting a bike tire. This last tip is the most effective, and I may even skip the first two. This brings up another related topic: heat treating the tires for longer wear. My friends here in South Bend at the Tire Rack will heat treat new car tires by use of a friction roller device before delivery. Heating the new rubber and letting it sit for a few days is claimed to promote more cross-linking of the rubber in the high performance tires they sell, resulting in better wear at the track. I've been doing this for my Aero tires with the kitchen oven as desribed above for a few years, and think the tires last a little longer, though I have no objective data. Check out the Tire Rack website. Randy wrote: I have V2 Aero 150 roller skis. One of the tubes just blew and I am trying to replace it. I have broken one tire lever trying to get the tire off.
