My question is would it be best to replace all 4 tires with some Goodyear TowPro's and should I have my bearings repacked???? Really don't want to any tire problems on this trip....Suggestions anyone???
Particularly if you haven't had bearings packed in a while, my advice is absolutely, get it done. With our travel trailer we lost both axles because our bearings weren't packed properly (repairs were covered by our dealer). And the axles had to be ordered, so the trailer was out of commission for a while each time (same bad pack job). With the first instance, the trailer was stranded hundreds of miles from home.
As far as tire speed ratings are concerned, you may have to do some web searching to find information--in most cases you'll find 65 mph, but there are some exceptions. Ours are rated a little higher, but I regard that as safety margin; I aim for 65 except for short spurts like passing.
