Hi everyone, my trailer uses 4.80x8 trailer wheels which I have run for 4 years now, every year I need to replace one of these tires due to inside tread wear, each time on the same side.<br /><br />Whats causing this? Air pressure is correct and bearings have been serviced.<br /><br /><br />Second, I just bought 2 new larger 5.30x8 (I think thats the model anyways, next size up from 4.80x8) trailer tires which fit just fine but since they are wider rub on the inside/back of the tire towards the springs. <br /><br />Can I just use spacers on the lugs to bring the tire out about a 1/4"? I have plenty of stud and everything else would then have plenty of room. My boat weighs in at about 1000 lbs so these larger tires would sure help out a lot, and reduce wear on bearings.<br /><br />Please advise!! Thanks<br />-John
