IMPORTANT tire question

Ok so I went down and bought me some NEW goodyear marathons at the store for my newly purchased 1973 Scamp 13'. The previous owner went and bought him some cheapy little 20 dollar jobbies and I didnt trust them for my up coming 8000 mile trip. I put the new tires on and the left(drivers) tire is just barely up against the fiberglass underneath where the right is a good 3/4" away. I figure i will drive it a mile to a friends house and see if it is an issue. I get to his house and take a look and can smell burning rubber. I look underneath and sure enough it was rubbing pretty good but didnt damage the tire seriously fortunately. FINALLY the question. I went down to my handy Pepboys and bought a 5/16 spacer, installed it, and everything seems to be ok. Does anyone have any experience with a spacer on a trailer. Supposedly the trailer has a new axel which I assume accounts for this problem. The trailer tows straight with no noted problems but I have only been at residential street speeds so far. Any help would be greatly appreciated. By the way the buddies house I went to welded me a nice new battery holder to the tongue of the trailer. I will take some pics soon to show it off and maybe give someone else a new idea.

THANKS IN ADVANCE

so you think the axle's off center a little? of was it rubbing on top? :conf guess it was on top if the spacer worked. I know some of them here have added spacers for ground clearance so give it a few days, and I'm sure some one who's done it will answer.

So when you added yours, did you re-center the axle? I thought they were welded on, but then how would you add a spacer? Sorry, I'm really ignorent on this.

Jana Journeycake PullsButtercupwithHoneyletsEscape,

I suspect Mike added a spacer to move the wheel out on the hub, not an axle riser.

Have you fully recovered from the Georgetown hoorah?

The spacer I added was to move the wheel out. It was rubbing on the inside sidewall.

spacing

use a measuring tape and measure the distance to the tire flange on each side, if there's a difference there's a problem.

If your axle is mounted on conventional springs, it's not located properly and it can work around and cause serious damage if it does.
If its a torsion mount type, it may have been welded in incorrectly, which will eventually cause you some grief.

Important Tire Question

I am assuming that you have the same size tires and rims on both sides of the trailer and you have a new axel. I would say that your axel was not properly centered when installed or you have a bent frame. Major problem! If this is the case you will need to (1) have axel removed and reinstalled properly and/or (2) straighten frame. Check alignment of axel with a simple tape measure to see if it is squared to the frame and equal on both sides from the back of the brake hub to the frame.

I have a solid axel with no up/down play. If the thing that comes up from the axel and then out to the hub is called the flange then yes it is at a different offset. as you look under the trailer from the rear the drivers side flange comes up even with the fiberglass wheel well where as the passenger side is offset ~ 3/4 " out from the wheel well. I hope this explains it and I am pretty illiterate when it comes to trailers. Sorry

Important Tire Question

Thanks for that quick reply!

Why were they built offset? Wouldn’t that track badly? But it would still have to be square to the frame, wouldn’t it?


Just asking...

the tires are brand new and are the same size as well as the wheels being the same size. with the spacer in place it seems to work fine and tow straight and gives me 5/16 mor room to move the tire out.

Mike,

OK. Tomorrow I am going to go out, crawl under my Casita, and measure to see if my axel is offset. I’ll let you know.

Enjoy your trip!
