Does anyone know what the tyre pressure should be for a camping trailer? It is the type with the little wheels (4.8 x 4 - 8), the guy in our local tyre place was unsure and said 30psi should do. any advice would be appreciated.

thanks for your help. i have tried numerous tyre manufacturer sites and outlets and while all recommend "the correct tyre pressure" no one "official" can give me a figure.
there must be some sort of formula to assertain the pressure for a particular size tyre and the weight of the vehicle it is attached too.

I think the 480/4.00-8 relates to the actual size of the tyre. that's the number that you quote to get a replacement that's the right size. The 8 at the end relates to an 8 inch wheel, which is the size of wheel used on most smaller trailers. It's really hard work getting a wheelclamp to fit it as well!! Got one from Towsure in the end.
Topicstarter had same sises and karenjg writes 265kg AT 4.0 bar upto M speedrated is 130kmph/ 81mph.
So if your axleload+10% reserve is 2x 265kg= 530kg. You need the full 4 bar.
If it is less, you could calculate lineair, not that bad.
Its B- load ( 4plyrated) so mostly you would expect AT 2.5 bar/ 36 psi., but this extra small tire is exeption to the rule.

I don't know if you're aware but, this thread is 17 YEARS OLD so hopefully the OP got this sorted.
This is possibly one of the oldest thread revivals I've seen 😕.
As well is two words!
