I had a trailer with those little wheels and tyres. They would be too hot to touch in the winter after a 200 mile trip at 55mph and well within their load range.
I think they're just too small for most applications and cant dissipate the heat well enough. hence the low highway speed rating?.
I must admit i don't like the old 10inch mini size much either for the same reason. Had a few of those fail on a micro-plus 502 trailer.
is there any speed rating on them??

I had that happen to me but not near as bad. When I went to the trailer garage they said it was because the tyre was 2 ply and should be 4 ply. My boat and trailer is 1000kgs.

Was that tyre 2 ply?


Ah.... wrote before you posted....

When I got my current rib it was at on a set of 8" "dinghy" wheels. Probably fine for the 200 yds it used to do per year at about 20 mph, but when I checked out, to get an 8" tyre rated to carry 3/4 ton per axle was about 100 / tyre!

I have 10" wheels on my trailer, primarily to reduce the likliehood of nav light removal on entry to the garage (and it makes launching soo much easier - I canlt remember the last time I had to unhitch to get the boat on or off). Got the higher rated tyres. More expensive to buy, but in the long run probably cheaper!

After seeing the photo in Mick's post and reading the rest of the comments and good advice here I've just been out and got a new set of tyres for my Rollercoaster 1 trailer. They were nearly 10 years old so clearly an unknown quantity! The originals were only 2-ply but I've upgraded to a heavier duty tyre with 2-plies in the walls and 4 plies across the tread. I always thought the originals looked a bit soft, even when inflated to the max, but these look much better.

As above max is max, but in the absence of manufacturer guidelines, it's better to overinflate tyres than underinflate them as sidewall heat is the silent tyre-killer which is why most "blowouts" are actually a slow puncture which became a very hot tyre which became a loud bang which became some dirty underwear.

As also suggested the problem is most trailer wheels (not just boat trailers) are stupid little pram wheels which then need the tyres to be over-engineered and over-inflated to carry the required heavy weight, which means the tyres are expensive and the ride is awful. The difference in the way my boat trailer rides between 195/50R13s at about 60psi and the current 235/70R16 at about 30psi is incredible. You now barely notice potholes that would bottom out the suspension before.

Not sure of the circumstances but I would say it may be due to the rubber being weakened by the trailer sitting in one place for a period of time. The damage is the same footprint as I would expect if an under inflated tyre was sitting on the ground.
