this is for track tires on a car that runs 20 min sprints, so don't care about fuel mileage. don't care about wet or snow - will use my streets as rain tires should it be raining at the track. currently have OZ Allegerittas so wheel weight is quite a bit lower than oem. yes, more tire does add more weight, however other factors can offset this - i want more front tire to improve turn-in so need to maintain balance in the rear, hence the question regarding performance of a 245/265 setup. would like rears a bit smaller diameter to improve torque/gearing and reduce sidewall (and, as a result, reduce tire weight). as bpd noted, spacers will increase weight, so overall fitment of wider setups becomes a consideration as well (ie, on front looking at a 7mm spacer w the move to 245).
bpd - 285's feel less nimble - is that because the rear gets glued to the ground? potentially not a bad thing if the fronts do the same?
