What size tires for my trailer?

I've put this in non car section as the trailer is a utility type, as per picture. Trailer was originally built to carry a race Kart and equipment, now gets used for hauling all sorts of stuff.

Finally decided I need to replace the tyres, wheels are 13" x 6J. Going to go for a cheap and cheerfull brand, but what size tyres should I spec? Want something fairly heavy duty as it uses the axle and springs from a half ton (500kg payload) pickup so can carry quite a load. Also it needs to be able to be used at motorway speeds.

You may well ask, why not just look at whatever size is on there now? Thing is I had the rims refurbished and the existing tyres were scrapped before I made a note of the size.

Cheers

165/13. Go for C rated or 6ply with the correct weight rating to be on the safe side. I'd be happy with normal car tyres....

Presume its unbraked, and hence has to be 540kg max-gross, hence around 500kg load, over two tyres, 250kg.

At which point as said, I see no reason why car tyres shouldnt be sufficient, at the right pressure, but would confirm their loading limits.

Hi Fred

I would think any street tyre of 165 X 13 or wider would do (But check maximum recommended rim width as normally you would fit a 185 tyre to a 6" rim) - I would go for Firestone if they still have damage guarantee.

Also be careful - I've seen tyres out there on new trailors with an 80kph speed limit which means that they must be available from dealers.

Thanks all for the responses

Eventually went with a 165/65 Yokohama car tire. Load rating is over 400 kg per tyre. Expensive tyre for a trailer but the cheaper tires had a higher profile so would increase the already nose down attitude of the trailer when hitched to my current car.

The spare tyre has 2 functions. When the trailer is empty and the removable sides are not fitted I can't see the trailer from inside the car, so I added the spare sticking up at the back to aid reversing.

Now I should really make some better sides for it, and also maybe get on with tidying up the rest of the trailer. But that's a slippery slope, where you soon find yourself into repainting the axle, springs etc..

Cheers
