Oversize front tire nearly touches brake arms -- safe?
I installed a pair of 35mm tires and the top/surface tread of the front tire nearly touches the brake arms where the arms go above the crown of the tire (not side clearance issue but top clearance issue) -- with just a couple millimeters of clearance. It will ride just fine, but is this safe? Do I risk a piece of road debris getting caught between the tire and the brakes sending me over the bars?
The bike is my dearly beloved 1976 Schwinn Super Le Tour 12.2, which I bought brand new with my paper route money. These days, it has Vuelta wheels with bladed spokes, a modern seatpost and saddle, modern dual pivot brakes and aero levers. I'm switching from all road riding, on 18mm tires, to mostly riding on Harrisburg's 19-mile Greenbelt, which is a mix of blacktop bike path, busted up concrete, gravel and some city streets. Oh, this bike is such a joy. 32mm tires were just fine, but I wanted to experiment with 35s for better control on the gravel.
Is this tight clearance between the tire's top crown tread and the brakes dangerous?
