I have a min no max and it runs 140/70/12 tyres. there seems to be a limited supply of these tyres but I see 155/70/12 seem to be at a good price.

Does anyone have any advice as to changing the size of the tyres are keeping the original and which ever way I go what make do i go for?

Hi Simon as long as the load rating is ok and there all the same should be ok the tyres are 15mm wider

Thanks Ian,

thats what I needed to know just need to find some now

Not trying to teach you how to suck eggs, you guys know more about this stuff than me but I thought trailer tyres should be heavy duty 8 pli ones.

The amount of load going through them and the pressure they are pumped up to is way beyond your average car tyre.

My trainer tyres (not sure what size but were available in a car size) are pumped up to 50psi and take about 380kg each. I dont think 13" car tyres have them specs.
