BMW Snowflakes with Avon Roadriders

[regomodo]

Hi,
I've bought some roadriders for my wheels but i've got a problem with both. The bead wont sit on the rim properly all the way around. I spent hours yesterday wrestling with them so I dropped them off with a bike garage this morning. I've just found out they can't sort it out either and they tried everything they knew.

Has anybody had problems with theirs before?

I had a heck of a time getting my avons to seat into the beads on my kawasaki. I am running 18 inch spoked wheels. I tried everything. I finally got them ALMOST perfect by slowly riding around the block a few times at a very low air pressure. I pumped them up where they should be and now they seem fine.

I haven't heard about this specific to either AVON's or the BMW snowflake rims.

So it's uneven? Were the tires really hard to install (i.e. getting the bead over the rim)?

Have you tried letting all the air out and spraying some soapy water on the bead? Sometimes you hafta pump them up to 40-50 psi before they seat properly...just be careful.

The tires were remarkably easy to get on. The rear only took 2 pries with the levers. The front was a bit more difficult to get the final bit over. However, they were much easier than the Pirelli MT43s i've had to fit before.

I tried that first then I tried neat Washing up liquid. The bike shop used some other grey stuff. They are currently at ~45psi, they were yesterday too.

I think I may do that, the others tires i fitted weren't quite right (nowhere near as bad as these) and eventually settled out over time.

A guy on Reddit recommended I use a bike tire specialist under the search term "ride in tyre fitting". Anyone know what they might be able to do instead?

I had a similar problem with the Avons. I like these tires a lot. and will buy them again, but they evidently have some odd issues. I mounted a new set on spoke wheels, wm-2 front and wm-3 rear. No issues mounting them, but at about 300 miles, had a SERIOUS out of round problem quite suddenly while riding the bike. Nursed it home and inspected it, let the air out, re-inflated it, up to about 80psi, (I know how dangerous this is, I was REALLY careful, and had the wheel covered with a heavy blanket, I do NOT recommend this!!), repeated several times, and it still was obviously not seated. Took the wheel to the local shop, thinking there must be some weird defect, where they did the same as me except lubed it up, and all was well after that. Have to say, I was a bit embarrassed, but I have mounted and worn out many dozens of tires and this was a first! This was on a PERFECT wheel, and suffered no loss of pressure (it had 28psi in it when I hobbled it back to my shop), and which has had likely 5 or 6 tires on it in it's life with me. VERY strange for it to slip off the seat like that while riding it, but while disturbing at the time, no worries over all.

90 psi sounds about right on some tire/rim combinations even with lube. At that it still sometimes takes a little creative slapping of tire onto pavement to get it to pop into place.

I finally sorted it out last week as it was low priority. I took them to car tyre fitting place that sometimes does bikes (MeritTyre, Andover) and they sorted them both out.

With lube, the rear needed 80psi to sit properly, the front (which they also reversed for me as I got the direction wrong) needed 75psi.
