I have informed myself on the Michelin website, what is written there counts, there are very often questionable specifications in many articles! I have 215/70/R16 Michelin tyres. As the chains are somewhat flexible, I think they will fit your tyres. In any case, I had a little reserve. In your case, they'll just fit tightly.
This depends on which winter tyres are fitted to your t5. Look at the tyres, note the size and then search. We were a little disappointed with these snow chains. Fitting them is quite a hassle. The grip in the snow and such is great and the chains are good to use up to 50 km/hr. But as I said: difficult to fit!
