anybody run into bearing problems when running a wider wheel than stock? i'll be going with about the same back space but 1-2" wider than factory. a little additional wear would be acceptable, i just don't want to eat bearings every track event.

As long as your bearings are in good shape and properly lubricated, it won't be a problem. I've been doing track events several years with the same bearings, running 16 x 8 rims with 245 V700's.

Just don't go with a rim with a lot of negative offset and it should be fine.
