Beware old tyres!

I'm using the Roadriders at 22 front and 26 rear and that works OK; might push the rear up a bit with the trailer behind the Matchless.

John I suggest you contact Avon about pressures because that's way too low for modern tyres with soft supple sidewalls. When I had Roadriders fitted they suggested 28 as the min pressure front and rear and 32 rear when loaded.

Good point, I think my tyres and tubes are from 1960!

Thanks, there are times when things are a little skittish but I thought that was me and crap riding! You are more robustly built than me, I'm only 12 and a quarter stones, but I'll heed your advice.

Was that for a single or a twin? I recall that the unladen weight for a single is 410lbs (no oil or fuel) but IKBA about the comparative weights.

Thanks

It's a general pressure for most tyres nowadays, some have more TT100's 30-32 depending on size etc. Too soft on a front will give very vague handling at times especially when pushing on into a corner. You'll not go far wrong with 28 front 32 rear with the trailer.

That's right Rob, and this is what I said all the way along: pressures have, by and large, increased by around 8lb to cope with softer modern compounds.

I'm actually nearer 18 stone and so I pump up the rear tyre to 30/32 psi. I'll try not to fall off again, especially since I've now replaced all of them on my two bikes. No guarantees though!!

Oo'er, I'd better go and sneeze in my tyres. Fitted a pair of Gold Seal K70's, 3.25/19 front, 3.50/19 rear and have been running with 24psi front, 26 rear.

I'm no lightweight so had better put more pressure in.
