Changing rims/tires on 1998 31' Excella 1000
I have researched the Forums for advice, but would appreciate specific advice in regards to my trailer. I currently have the original 15" steel rims on my trailer. I will have owned the trailer for a year in January and just towed over 8500 miles this past summer, without any problems. It is coming up to time to replace the tires (previous owner put on new "off-brand" tires 2+ years ago, so there is about 12000+ miles on them). I am considering going to 16" aluminum rims and tires. Any of you that have the same trailer, were there any wheel well clearance problems going to the 16". I know people have varying opinions on brands of tires... What I am interested in knowing is it "worth it" to go to 16" as opposed to staying at 15"? Ride, control, towing, etc. Any particular brand/model of rims? Sendel T03 seems to be most popular. What about metal stems as opposed to rubber?
Thanks for any advice.
