Thank y'all for your replies and questions.

I just measured the over-all width of the rims: --- 26 millimeters.

I normally ride a full suspension MTB converted to street use. This new bike, a Raleigh with Shimano STEPS, has no suspension and its stock 40 mm tires are pretty stiff; I am looking for the best ride possible and Big Apples look to be the best in that regard.

I hope that someone out there can answer my original question: How wide are the 55 & 60 mm Big Apples?

BTW: The power boost of the STEPS system allowed me to average a little more than 20 mph on the 22 mile trip home from the dealer, into a 10 mph headwind and some hills. I would have only averaged about 8 mph on my normal bike. I used one-third of the battery's capacity and still got a healthy work out. The electric assist will allow me to go places and do things that would otherwise be difficult and unlikely. -- JM
