Ouch!! (Tyres)

[Nabsim]

Reading up while I was waiting for yet another tyre fitting this morning on my bike (Another £175) I read the the Camping tyres offer better stability than standard ones. Its impossible to tell really but one of the massive differences I noticed on our new van compared to the old one was the lack of movement and sway on the motorway when passing large vehicles (or on the rare occasion one passes me. ). Its solid as a rock but then its a heavier van. The old one with so much weight high up and possibly with a bike on the back would wobble like crazy.

I don't get movement on motorways either Barry even though I had read that Sprinter based vans were all over the place. I don't know if its to do with the rear air assist, the camper tyres, a combination of both or something else

That's true for commercial tyres. Not so much for camper tyres.

CP tyres differ by having thicker sidewalls to cope with being kerbed.

This gives a harsher ride, particularly because they also need to be run at higher pressure - because the thick sidewalls build up heat as they flex and have more trouble dissipating it.

So what is a suitable and safe pressure for a C tyre is probably not safe for a CP tyre.

Moral of the story: if you want a good ride, don't buy CP tyres.

Think most on here are past the latter.

It's not just about tyres though your entire running gear, steering and chassis is far newer. You can't just narrow it down to one thing.
How many time do you hear the phrase "You get what you paid for", Yes sometimes you do and sometimes you get even more, you get shafted as well.

If you look at the profile of my van its a ferkin big 8m slab with a humongous luton. In that Luton is some fairly heavy stuff. Anything that helps stability has to be a good thing. Interesting that you said that Continental told you to run them at 60-65 PSI though. This contradicts what others have said regarding keeping them at the manufacturers recommendation which is 80 PSI for my van apparently. They are vanco camper 225/75 16cp tyres but not sure if 8ply or 10ply. I might contact Conti and see what they say. I found another thread on FUN just now which is as controversial as this one is turning out to be. None the wiser really.

C vs CP tyres - ride comfort only

I have a 4T van, only bought it end of last year, so not owned too long but the front ride comfort is AWFUL!!! (a Class Hymer Fiat based) It has Continental Camper CP tyres which are almost brand new so I’m reluctant to change them but has anyone gone from CP to C and noticed a step change in...

Yes I appreciate that. Bigger wheels beefier everything and of course nearly two decades younger than the old one. There is no way of putting it the test though so I guess I will never know. I might have saved £50 per tyre maybe but what if it turned out to be a big mistake?

You need to go faster passing the trucks

I bet you're so glad you asked Barry.

Must have cheered you up no end today, I recommend drinking heavily!

That's why I just went out and bought 2 tyres and didn't ask the question. Tyres are always very subjective

Great stuff, the info needed.
If this is the tyre, looks like they are 3PMSF and 10 ply. 118 load rating, so need to check that, I'd guess it's fine. Probably could have got to a 120 rating with a commercial tyre, perfectly good tyre

Just ask yourself. How many vans do you see running around everyday being shown no mercy and how many do you ever see with a flat tyre. All on commercial tyres.

A bit of advice here Barry and if you do nothing else then act on this one.

Contact Continental Tech Department, give them axle weights and weights you normally run at and ask them what they recommend. When I did it I only gave maximum axle weights as I would normally be around full load and I run what they recommend.

Continental are the tyre manufacturers and know a lot more about what's best to run at than the vehicle manufacturer, they usually just say whatever is stamped on the original tyres.

Of course if you find the ride is good as you have them then you can always run at what's stamped. Its usually when you get less than great road surfaces the lower pressures pay dividends

I wouldn't have a problem running on ordinary van tyres at all so long as they had the proper load rating. If camper tyres do last longer this can be offset by the normally lower cost of a normal van tyre anyway

They are actually 116 load rating if you look at the pics.

I have done exactly that just now and sent them the current weights on both axles from the weighbridge taken the other week. I have added 100kg to each though to allow for extra load for a big trip, fuel etc.

The whole van is minging. Its on the list.

 

[Nabsim]

Looks clean to me lol

Blimey Neil, where in the UK are you going to get anything other than less than great road surfaces?

NOOOooooo ask on the forum it's good for at least another 100 posts.

The tyre pressure stamped on a tyre is a legal requirement for Canada/ North America. To show max pressure allowed.
Nothing else....a mate managed a tyre firm for 40 years.
