Trailer tyres

Been looking at my tyres today while fitting my new mudguards and one of them has a dodgy looking indentation in the side wall so it needs replacing. But with Anglesey next weekend time is of the essence! And i need some advice.

What load rating do I need? The current tyres are not a matching pair: one one side is a tyre rated for 425kg at 32 psi, and on the other is one rated for 900-ish at 64psi. My back-of-a-fag-packet calculation is that the whole rig is about 1000kilos (700 for boat/engine/gear, 300 for the trailer) so if the load is spread over two wheels then that's 500+ per wheel right?

The 32psi is a car tyre, the 60psi is a commercial/van tyre. My trailer came with 4 commercial tyres (& still has) I'm guessing that someone has replaced one of the original commercials with a cheaper car tyre. Get a pair of commercials on there pdq. They will be around 100 quid each for good quality ones. Cheap ting tongs are about 45, you gets what you pays for.

depending on how good your rims are it might be worth ring SBS up for a price for a set of rims & tyres, or I seem to remember Hadd having a good contact local to him, maybe worth a try, but whatever you decide like Pikey Dave says needs sorting before next weekend

The rims are OK so I'd like to avoid having to buy full sets if poss. When I'm phoning round for tyres tomorrow I need to know what I'm asking for. I need something with a 500kilo+ load rating? Got to cut to the chase or I'm going to be trying to get there down the Leeds Liverpool Canal!

look on the existing van tyre & copy the spec, it will probably be an 8ply. Just tell them the size & load rating.

What trailer have you got, whats its rated weight ? Regardless of whether the tyres are safe, the tyres need to have a capacity equal to or greater than the plated weight on the trailer.

I would think the 425kg rated tyre is a car tyre, it needs to be replaced with a 4, 6 or 8 ply reinforced trailer tyre. The 900kg tyre may be the correct tyre (if your trailer has a capacity between 1500 -1800 kg). Unfortunately trailer tyres are expensive, but messing about with under rated tyres can only end in tears.

Quite a few places do them mail order, but if you need one tomorrow your best bet will be a dedicated plant, agricultural or boat trailer place. Indespension in Bolton stock them. As Chris says, its often easier to replace tyre and rim for not much more than the price of the tyre alone.

Hi Dan, it would be cheaper to go to indespension & just buy the wheel with the right tyre on for the trailer for what they cost, it would save a lot of messing about as well
