Hi all

I have some Mavic Aksium wheels specs are:

Material: S6000 Aluminum
Height: 21 mm
Joint: sleeved
Drilling: traditional with H2 reinforcement
Brake track: UB Control
Valve hole diameter: 6.5 mm
Tyre: clincher
ETRTO size: 622x15C
Recommended tyre sizes: 19 to 32 mm

More details: http://www.mavic.com.au/wheels-road-triathlon-aksium-elite#.VDIR8mccSUk

I would like to know is it SAFE to put a pair of Schwalbe delta cruiser tyres on the mavic rims, tyre size is 700x35C

The bike is a flat bar commuter, me and the panniers I carry might push 120 kg at times but mostly about 100 kg, I ride on the road / paved bike paths, rarely get above 40 kph, and never by much, don't corner fast but a lot of start-stop and can be heavy braking.

Cheers
Sam
 
32 mm vs 35 mm isn't much difference, go for it. If you want to be careful, don't use full rated pressure.
 
Just in case anyone is interested, http://www.sheldonbrown.com/tire-sizing.html has a chart that suggests that 15 mm rims can handle 23-32 mm tyres but "Note: This chart may err a bit on the side of caution. Many cyclists exceed the recommended widths with no problem. "

he also says:

Although you can use practically any tire/rim combination that shares the same bead seat diameter, it is unwise to use widely disparate sizes.
If you use a very narrow tire on a wide rim, you risk pinch flats and rim damage from road hazards.
If you use a very wide tire on a narrow rim, you risk sidewall or rim failure. This combination causes very sloppy handling at low speeds. Unfortunately, current mountain-bike fashion pushes the edge of this. In the interest of weight saving, most current mountain bikes have excessively narrow rims. Such narrow rims work very poorly with wide tires, unless the tires are overinflated...but that defeats the purpose of wide tires, and puts undue stress on the rim sidewalls.
