Wide tire bead on narrow bead rim
#1
I have a touring bike that has Mavic MA2SBP rims marked 622 x 13. For quite some time I have used a set of Vitoria 622 x 35 tires successfully on these rims. I am starting to need a new set of tires and I like the Schwalbe Marathon Plus Tour HS 404. I would like to know if I can put the 700 x 40c tires on these rimes without a problem. If not, would the 700 x 35c tires be better? I read different things about this. Some sites have said even the 700x 35 are really too wide. Others say because of the tight bead grip of the Mavic rims width is not an issue.

Anybody have any thoughts?

Generally the rule of thumb was 1.5x to 2.25x; for 13mm (inside dimension) rims that would mean 20 to 30mm wide tires.

As the ratio goes higher, the bikes handling will be more squirrelly - meaning that its response will be non-linear. For example, leaning into a curve, the cornering forces will gradually increase (like they should) then suddenly decrease then go back to what they should be.

I have run 32-630 Armadillos and Bell tires on Array 630-13 rims with no issue. But I like the performance and feel of Kenda 35-522 on Velocity Dyad rims (622-18) much better.
