Wheel Size

Hi all, new to the forum. Got a 75 Surf Side three years back. A couple of years back I replaced the tires. A previous owner had made a number of changes, one was the tires. It had 14 inch tires (car tires) on it. My local tire dealer replaced them with trailer tires. The outside profile was slightly bigger in diameter than the car tires and I was worrying if they were rubbing at times. They have worn bad and I read somewhere trailer tires arenít currently made as well as other tires. I have bee thinking of dropping down to 13 inch to make sure I have good clearance. The trailer still had the manufacturer spec sheet with it and the only information on tires was ďminimum 13 inchĒ. Any one know what size should be on this trailer.

Darn I wish I knew more about Surfsides..I dont, but I still had to reply since your name is so cool!
I might add that IMHO there are many inferior tire brands. And for camping trailers I am confident that Maxxis, Carlisle and perhaps Goodyear produce good tires. In any case.. car tires are not what you want. I have no idea what size will be safe for you to use (clearance considered). Excessive wear is a concern and can have many causes from misaligned axle to worn bearings to inflation errors to.. etc.. the wear pattern can help to narrow down the cause. GOOD photos of the wear on the tires might help (or might not).

Agree. You don't want car tires (P radials) because the sidewalls are too soft, and the trailer can tend to wander and not track straight. Some people use LT (light truck) tires, which have stiffer sidewalls for load bearing, but you should be fine with a good quality ST radial.

If the tire size is the problem and it is rubbing, you should be able to see black marks in the wheel well. In the absence of that, I'd look for other causes of unusual tire wear. Underinflation, an out-of-balance wheel, or a bent/worn out/misaligned axle are all possibilities. The pattern of wear provides clues.

Yes, I donít want car tires, thatís the reason I changed what the previous owner had put on it. I donít see any rub marks I the shell well, but they definitely donít leave too much clearance in my mind. Canít remember what brand they are, but pretty sure not Carlisle or Goodyear. I have Carlisle on my utility trailer and they have been great.

Thanks guys for input, will keep looking

Trailer wheels are nearly all ZERO offset.
If you have car wheels on the trailer any offset can cause a problem.
Also Small travel trailer wheels are seldom more than 5" or 5.5" wide (often less.
Older smaller trailers often came with smaller tires which are no longer available (sometimes 155s) Not sure about yours,but...
It is possible that your trailer started life with 155/80-13s with ZERO offset 4"wide wheels.

Probably plenty of clearance for185/80s and 5" wide ZERO offset wheels.
Not sure about your particular trailer, but oversized wheels or tires are not needed and often have limited ability to fit.


A few minutes with a tape measure and a little research can solve your concerns.


Also an older trailer can often have settled a bit even with a good suspension, which could exacerbate any fit issues.

what sort of size car tires are you talking about here?

I imagine a 1975 Surfside is a fairly small and light trailer ?

Given it is a 1975 trailer, without additional information I would say your axle is shot. These torsion axles were originally designed to last 15 years. at the 46 year point, its time.

Many of us with Trilliums (look very similar to Surfsides) have been using 14 inch Ford Ranger wheels to replace our stock 13 inch wheels.

Not sure where that "15 year" thing came from.... 46 years ...Probably!
Of course the Trillium has no problem with negative offset since the wheelwell is open.



Just as a point of information, early Rangers did have 14" wheels with a 6MM negative offset. The aluminum wheels were 5.5"- 6" wide.
Steel wheels were 5" or 5.5" as I recall (been a while)
Good choice for some small fiberglass trailers but certainly not all.
The early 4X4s and newer 4X2s usually had 15" wheels, many were 20MM offset, so be careful when searching around for old Ranger wheels for your fiberglass trailer.
