Run the same set up on my wife's grocery getter and no problems there either.
Wow! I didn't know you could get that high and narrow with straight sided rims! The steel rims I have are engraved with 1 1/4". Can I go narrower than 1 1/4" or should I stick with the wider tire? I would like to go narrower to reduce rolling resistance but don't want to sacrifice safety on these straight rims. ATM I don't go on long rides so comfort isn't a huge issue. I'll usually go 10 miles max. at the moment.
