EXTRA INFORMATION
Size
4.10/3.50-4 inner tube: 4 inch rim, tyre width between 3.50 and 4.10 inches. The dual designation means the tube covers both widths, the rubber adapting to either.
This is the smallest rim in the catalogue. Check the inner diameter of the original tube before ordering — the outer size alone is not enough to guarantee the fit.
90x90° valve
The valve is angled at 90 degrees on both segments. This double bend brings the inflator head parallel to the rim, where a straight valve would be unreachable.
On a 4 inch wheel the space around the valve is very limited — the angle matters all the more. Check the one on the original tube before ordering: this is the leading cause of error on this product family.
Fitting
Sold individually. Inflate the tube slightly before inserting it into the tyre to avoid folds, and make sure it is not pinched between the bead and the rim before bringing it up to pressure.
