Thread: Caravan tyres

I like the solid centre rib

They look similar to what we had mate, the ones we had were a bit squirmish until they got some heat into them and they perfect, they never gave me a bad feeling once

The website actually uses the term "rigid"

how about these bad boys
the CW 25



185R14C 102/100R 5.5" 650 188 E5086

Yes mate look good, good load and speed, what about going the 195's the wider the better well so the wife says

The van has a severe tyre size limitation,,
the rears meet the wheel arch on the upward swing,, have massaged the problem a bit but limited to around 650 OD give or take,
width is no problem

I don't do a lot of towing, and when I have, I haven't really paid much attention to detail so to speak.
But coming up from Melbourne yesterday, I passed several vans, both duel and single axle, and I was surprised to see just how differently the tyres behaved on the various vans.
One in particular almost saw me pull the driver over to tell him to lower his pressures. A Coldstream (?) I think, single. As he was moving along, the tyre was bouncing on itself, and you could see this transferring to the car. Must have been very uncomfortable for him. The tyres looked in good nick, but of course no way of telling what they were, but surely this scenario can't be good, for either the tyre, van, car towing, or the driver (stress of some description surely).
I don't know if my thinking is anywhere near right, but a car generally is heavier than a van, and we run tyres around 32-38 psi, then wouldn't you run the van tyres at near the same sort of pressures?
As you watch a tyre on a car, you see it absorb bumps with sidewall flex at the same time springs are doing their thing. The leaf springs on the trailer in question did not seem to be moving at all.
As I watched a duel axle trailer, I noticed it was in almost the same state which had me wondering even more, although his pressures on the trailer seemed to be less, but still had that bounce to them. It was coil sprung, so the springs were probably doing better at their job than the leafs.

So how much punishment do your trailer tyres end up taking whilst you have them at a high pressure. It amazing how many trailers, of all descriptions, you see that have one tyre at lower/higher pressure, either on the same side or the other side. Seems a lot of people really don't pay much attention to this unfortuneatly

Well that's a buggar Pedro, from that the 185's will have to do then
