Inner Tube Choices - LM3

[Vince in Milwaukee]

So, I already have my rear tire picked out for LeMans III, but need to make sure I purchase the correct sized inner tube.  Going to some web sites is like sorting through a jungle of numbers, ratios, sizes, etc...The tire size is a 110/90-18.  I know that there are quite a few old Tonti framed owners on here; what are you using?  Thanks in advance.

Michelin, Metzeler,  Continental,Avon,  Pirelli, IRC, Kenda. They all work. Using heavy duty type tubes  as in trail bikes , makes them  more cumbersome to  fit in rims due to their thickness . Alternatively you could go tubeless. Safety beads were not built in in the FPS wheels used on vintage Guzzis so the decision to go that way is purely yours. I have been running cast Guzzi wheels tubeless since the mid 1980's without any problems.

When I need tubes I try to buy ones made in Japan not China,Bridgestone are good.

My tubes from Japan have lasted 47 years without a single flat,

You need a 3.50x18 inner tube. They're usually pretty cheap, so I recommend you buy a spare just in case.

Go with the Michelin that are of natural rubber. Some of the weird brands split when perforated, whereas the naturals won't do that. I'm also running tubeless on those rims. They should have stampings on them, and depending what they are, even though not rated tubeless, will work and be safe. Of course, at your own risk 

There are a bunch of threads on this forum in regards to tubeless, and here is one of them: https://wildguzzi.com/forum/index.php?topic=76391.0

I'm running my LM2 on tubeless.
