Okay so a day or 2 after posting my last post in this topic, I spoke with a Sava dealer here is Oz and he ordered a couple of tyres for me. That's back in November and he was just ordering a new shipment of tyres and got a hold of some for me. Not sure if you can get anything like this in Australia, but from all the tyre dealers I've spoken to, they all said to goto Sava for my wheel...
I notice today that's quite a long wait for tyres... But holey crap who cares!!!
Check this out....
Thats my original BMX tyre on the left, and 2 new tyres on the right.
Both tyres are 16"
inside diameter tyres that fit the cast 20" wheels PERFECTLY. A normal BMX or bicycle tyre I find you can nearly hoola hoop over the cast wheel, when I trial fitted the big mother I nearly needed a tyre lever to get it on there.
I tried to show the difference here:
(BMX tire on top, new Sava 'moped' tyres underneath)
You can tell a bit the inside diameter is larger on the bicycle tyre compared to what I have now. This meant I had to run low pressure in my wheels since I've had them - as fully inflated my standard BMX tyres would 'balloon' making me bounce up and down like a cowboy.. And I like tacos not sausages so that wasn't for me haha
I have 2.5" for front, 2.75" for rear just as I posted in November:
2 1/2 -16 42 J TL/TT REINF.
2 3/4 -16 46 J TL/TT REINF.
These are some serious tyres and I just need to goto a tyre dealer tomorrow for some decent tubes. No idea if they will increase or decrease my speed. They are overall bigger (taller) but they are heaps heavier. They are however, speed rated at 150km/h so that's a good thing in case my bike gets struck by lightning one day, at least my tyres will be okay with the speed lol
Anyway YAY - it worked out. Personally I know the 16" and 18" cast wheels work fine with bicycle/other general tyres but these 20" wheels were a real head scratcher..
Haha look at the difference:
Before.... (inflated)
After (not inflated....)
The wheel apparently can take upto a 3" version of these, but I was scared about chain room.. I'm still thinking I have to get a 5 speed rear freewheel and space it out from the hub with this chunka on there...
You can get different tread versions but I wanted this style, you will see once I finish re-building the bike
