So far, I have fitted tannus tyres to 3 wheels. A 28mm and two 32 mm tyres. Had one skid in wet weather that saw me do a complete 180 in the road, but other than that they're ok.
For those that want to fit the tyres themselves, save yourselves a lot of swearing and buy a deluxe fitting tool for about 17 quid. Makes life so much easier compared to the tool given with the tyres. It's the one that looks like a pliers.
