Hi, another newby question.
The inner tube i've removed from my front wheel says 300/350-10. Will 350/400-10 be ok?

UPDATE...
Not sure if this is a brand issue or size issue, but when fitting the Vee Rubber 350/400-10 inner tube with a 90 degree valve, the valve ever so slightly catches the brake. I've done a bodge to hold the valve down a little but thought i'd share this info.

Its the brand, some 90 deg valves are fine on front.
Some are longer than others.
Change it, you dont want any stress or impact on the valve.
On vespas ive only ever used Michelin Airstop with no problem on back or front.
A learning curve.....that what scooters are.
