I would go for stock imperial sizes.
They're still tubeless but in particular the rear will wear better.

If you want an innertube there's one here.

So this is probably a stupid question but here goes anyway, if you don't put an innertube on a spoke wheel, wont the air escape out through the spokes? :roll:

Not if its a bmw. Think guzzi are the same. The spokes are fitted in the side rather than the middle in a seperate bit on the rim etc so not actually inside the tyre.

BT -45's Tires

Thats a very good choice of Tire. I run BT 45's on mine and there brilliant ,very planted ! & definitely stick to STD sizes Tires on Std rims or you will regret it ...handling will be lesser ! Try not to get caught up in this whole big tire thing , as there's a lot more to it than meets the eye . It will rob your H.P. if you have 125 hp plus, well yes .....you need a bigger footprint on the tarmac then & you can afford to sacrifice some Ponies for the privilege. This is why you won't see 120 front & 200 section rear tire's on a Manx Norton or G-50.
