I was wondering.

Is there any problem using 2 different tires on the same bike?

Say for example a fat 2.35 Big Apple in the rear for a more comfy ride, and a thin 1.3 racing tire in the front of a 26" bike?

would there be any gain at all vs. using 2 Big Apple front and rear?

I'm actually planning to keep my 2.25" Racing Ralph on the rear, and putting back the SportContact 1.6" on the front

i do quite a bit of off road riding, i figure the front wheel is just a driver, it doesn't really do much, all the weight is on the rear tire, and the push power comes from the rear wheels anyways.

on asphalt road i'm expecting to run normally, but going off road on the SportContact not sure if the front will dig into the dirt (grass) when it's too moist.

the Racing Ralph being so wide at 2.25 it has no problem at all on the moist dirt surfaces, but... can't say the same for the 1.6 SportContact street tire.

Anyways what do you guys think?

Currently using Racing Ralph in both front and rear.
