My oem goodyear 265-50-20 tires on my 03 fx45 are nearly shot after only 37kmiles. Replacement oems are nearly impossible to find. I have been told that replacing 265-50-20 with 285-50-20 is a great move; and I have been told that it is a terrible idea ( both pieces of advice came from reputable tire dealers). Can anyone provide a tie-breaker on this advice. I would like very much to go with a wider tire.
