I have a set of Alex rims & find tyres are incredibly tight fit on them.Anyone else found this with Alex rims?

More learned cyclists are likely to correct me, but I reckon tight tyre fit has more to do with your choice of tyres than your Alex rims. My rims are Ksyrium SL but when I was rolling with Michelin tyres, they were very tight to remove and put back on; in fact they were downright frustrating. I now roll with Continental 4000 tyres (on the same rims) and they are very easy to work with; life is a breeze when I now puncture.
Ask some mates if they have spare tyres (that are different to yours) laying around and try them; it might work.

I've found that all folding tyres are pretty tight on all rims when new, but they get looser with age.
The one tubeless-compatible wheelset I've used, Shimano WH-7801, is noticeably tighter than the others, though, and
the tyres really lock into place - they have to be snapped out of the rim's hook, even when deflated!
They're a pain, but it's worth remembering that a tight tyre is less likely to roll off the rim if you corner while losing
pressure. Zipp claim to deliberately oversize their clinchers for this reason.

Hi,
it's been awhile since I've had the opportunity to logon to cycle2max. Good to be back and read all the fine posts!
I use my tyre levers to put the tight brands back onto my ksyriums. But you need a strong set of plastic levers.
Vittorias corsa are always tight to put on but I like the rolling qualities (smooth & grippy in the corners).
Funny that re: Michelin tyres. Folding ones have always being easy for me, so that leads me to believe rims would also contribute to this issue.
It's always comes down to the quality & consistency of the rim manufacturing process, which you end up paying for.
I find with cheaper rims it's pot luck whether you get a good pair. ksyriums are alway consistent, but they do sometimes break a spoke with heavy use, which is neither here nor there.

I did read somewhere that Alex rims are a little bigger than 700c - that would account for tyres being tight

Been on quite a few Mega Bike rides with Noel Mc Carthy.....the occassional flat tire doesnt seen to worry him - watching him pull the tire off a rim (any rim) without levers is amazing (and yep he also can get a tire back on the rim no levers as well - this guy is a legend......( never seen him inflate a tire with his mouth yet - CO2 is the way to go here)

I once broke a plastic lever getting a tight tyre off. Not on the road, luckily, but it's a worry. And regarding the breaking spokes, I've been told that it costs $30-40 to get a Ksyrium spoke replaced by a shop (it's a special order and needs a custom tool), which certainly is "here or there" in my book. Ouch!

Hi Michael,
I good a good deal from Blackwood Mega bike when I broke 10 spokes on my Mavic Ksyrium SLs. Still going well and staying true and round no problems.

My Ksyrium SLs are my one and only wheelset (don't have separate 'training wheels' and 'racing wheels') so they get a workout , but I've only broken three spokes in a couple of years.
What do you more experienced cyclists do when you break a spoke and you're a long way from home? Do you call for the Mrs. to come and pick you up or do you have some mechanical solution that you could share with me? I've been lucky so far because my broken spokes have only ever been in races so I was able to DNF and get a lift in the sag wagon, but my time will come far from home. Advice/suggestions/solutions welcome.

Hi, Michael,
it's the red spoke with the decal that cost that much, the rest are the same as any other top end wheels, around $3 to $5 ea. Labour costs varies.
Aluminium spokes are always a worry regardless of manufacturer (a riding buddy broken a few spokes on his fulcrum zero, contrary to the "bulletproof" testimonials I've heard...!)
If this concerns ya, then stick with more reliable SS spokes..
No tips on riding home on a broken wheel, or anything else broken for that matter. It's the buddy, sis, or taxi 4 me...just never go out without telling someone who cares.

Your problem is not going to be with the rim, it will be with the tyre. I had the same problem earlier this year. Was running the stock Hutchison tyres on my Scott which were a paid in the ass to get off. Have now switched to Conti GP 4000 S which are fantastic. I can get the tyre off with minimal use of tyre levers and back on without them at all. Also, they're magnificently resistant to punctures. Touch wood, I haven't had a puncture with any set yet, I've actually worn them out before I got a puncture. They are quite expensive ($110 per tyre retail in shops) but off PBK, Chain Reaction, Total Cycling, etc. you'll pay less than half that.
In regards to tyre levers, I have a pair of steel-cored tyre levers (in other words, there is a plastic outer layer to protect the rim with a steel inner layer so they don't flex. Can't remember the name but they're awesome.

Nic,
with Mavic Ksyrium Elites and Continental 4000S tyres I just use my hands to get the tyres on and off. I don't even carry tyre levers any more.
