And do buy TyrePal!Because lower pressures mean more sidewall flexing.
More sidewall flexing means more heat generation.
Thicker sidewalls means less heat dissipation.
More heat generation and less dissipation means higher temperatures.
Higher temperatures means more risk of blowouts.
Blowouts mean more risk of death.
If you look at the makers' charts, for C tyres, then pressures vary by loading. For CP tyres, regardless of load, it is usually '80psi unless the ride is too harsh, then 65psi'
Just don't buy CP tyres.
Tyre bay cannot find the leak, no budgies on my part.Just fix the problem then ....
Jeez bodgery of the finest degree
In my experience Continental are perfectly happy to advise on pressures in CP tyres dependant on loads, they are also happy to recommend certain of their C tyres for motorhomes, it is Michelin who will only recommend CP tyres for motorhomes, and only recommend maximum pressure for rear tyres, this is due to a court case brought against them after they recommended a pressure for a given axle load but the motorhome was subsequently loaded to a higher level.If you look at the makers' charts, for C tyres, then pressures vary by loading.

Conti have not replied to my email sent last Friday as yet regarding advising on tyre pressures for their CP tyres.In my experience Continental are perfectly happy to advise on pressures in CP tyres dependant on loads, they are also happy to recommend certain of their C tyres for motorhomes, it is Michelin who will only recommend CP tyres for motorhomes, and only recommend maximum pressure for rear tyres, this is due to a court case brought against them after they recommended a pressure for a given axle load but the motorhome was subsequently loaded to a higher level.
It's been 10 years since I last contacted Conti, so it's possible they have gone all 'elf and safety' since over pressures, but they still recommend a tyre for my van which Michelin refuse to do. They did have a online page showing recommend pressures, not sure if this is still available, and I'm sat in waiting room on me phone, I'll give searching for it a miss for now.Conti have not replied to my email sent last Friday as yet regarding advising on tyre pressures for their CP tyres.

3 ins offset will put a strain on the wheel bearings all round and alter the front geometery, this happens to folk who fitt wheel spacers, dont do this.Neil I've went from 225 x70 x15in 109/112 rated to 225 x 75 x16in 120/121 rated so it has raised the ride hight altered the gearing probable altered the geometry of the suspention and drive like a dream so what do you think lololol
Ps I run the tyres at 60psi all round+ the offset on my alloy wheel I have have given me a 3in wider track than standard.
This could go on for ever. To my mind, if the tyres are correct size and meet the axle load ratings and have any other qualities you may need (3 peaks maybe) then I don't see a problem.
Tyres originally fitted to motorhomes are usually of a Light Commercial (“C” or “CP”) type. CP-type tyres are now widely used as they have been designed to cater for the higher loads imposed by motorhomes, especially when fitted in a single formation on the rear axle. The original tyre specification should not be changed without consulting either the vehicle or tyre manufacturer. Deviating from the original specification of tyre is likely to have an effect on the handling and general characteristics of the vehicle. Never replace the tyres with ones of a lower speed rating or load capacity.
You’ll be treading on thin rubber in ten year timeI have bookmarked this thread so in ten years time (hopefully) when my tyres need replacing ill look at it and never ever ever ever start another tyre thread.![]()
Bad idea as outlined by @trevskodaPs I run the tyres at 60psi all round+ the offset on my alloy wheel I have have given me a 3in wider track than standard.
Because as long as you don't change the offset too much, the extra strain is minimal, but extra strain there is.All I can say its has worked for over 10 years so why has none of theses faults show up ?
Not sure what I did but I had typed a bit more than is in my post. It should have said that the second paragraph was what Tyresafe.org had to say about it (C or CP tyres).Neil I've went from 225 x70 x15in 109/112 rated to 225 x 75 x16in 120/121 rated so it has raised the ride hight altered the gearing probable altered the geometry of the suspention and drive like a dream so what do you think lololol

You have a reliable van - still.Vans in for MOT. Its passed but all four tyres are cracking at the sides. They are the continental camping tyres but all of them are ten years old so they have recommended replacing them. £230 each!!Ive said go ahead as I really have no choice. I've seen debates about whether normal van tyres will do and obviously they will likely be £100 cheaper each but with it being a 4.25t van, carrying the scooter etc and also stood for months on end I guess its probably best to have the best tyres suited for the job.
What with the service and MOT on top thats my day ruined.![]()
What Tyresafe haven't addressed is that Conti make VancoCamper tyres as C and CP, as in some circumstances the CP standard doesn't allow a high enough Load Index for the size of tyre. Conti claim the VancoCamper C is built to the same basic standard as CP but 'stronger', but Tyresafe say the C can be varied in pressure, but the CP can't..
