I know this is an older thread, but it came the closest to answering my question.

I had 28mm tires on my cross bike for long road rides and even used them for a little bike camping with my daughter- all on crushed gravel trail. They worked alright, but the ride was a bit harsh so i looked through the forums and decided to buy some 35mm Panaracer Pasela TG's for future riding. I got the tires yesterday and put them on my bike. They seemed a little overkill, but the ride was pretty plush. The only real issue that I have is getting the front tire to fit with my fenders on- the rear tire fits fine with the fenders in place and I bet I could even squeeze a 38 in if I had to.

So, I was thinking about picking up a 32mm for the front and leaving the 35 on the back- keeping the other one as a spare. How many others on here use different width tires for front and back wheels? Any idea how it will effect my handling? Or, should I just monkey with the fender a bit more and get the 35 to work smoothly?

Thanks,

Jon
