i'm moving from dayton, ohio to lagrange, georgia. distance is exactly 600 miles. i have a small 14ft fishing boat on a trailer that has small rims and tires. i dont know the exact size of rim but it measures 9 inches.thats just the rim itself. the tires look new. they say titan st on them.the only #s on them say 4.8-8. i'm assuming this may be a 13 inch. were im going, there is a lake and i could probably not get another boat like this one for the price i payed for it. i'm just wondering if this little trailer would ever make it 600 miles. i have taken it on 1 1/2 hour trips and felt the bearings and they felt fine. so i'm looking for either someone to tell me not to even try it, or no dont even bother.
