I am about to purchase a new tyre to fit onto my spare wheel, so wrote to Continental for answers to a couple of questions, see below.
I have a 3.5T motorhome on 215/75/R16 Continental Vanco2 tyres. I am looking to buy another tyre same as above, to use as a spare fitted to a rim and correctly inflated, but could you answer these questions please;
1, the tyres normally are inflated to around 4 Bar, what sort of valve should I ask to be fitted for this sort of pressure ?
2, someone suggested getting the rim powder coated before fitting the tyre, is this a good or bad thing to do as regards leakage etc ?
3, I have been advised that all tyres should be changed around the 5 year old mark, irregardless of wear, due to UV exposure. If my spare tyre was never exposed to sunlight, ie never used, would this advice still apply ?
Answer from Continental;
Good afternoon,
Thank you for getting in contact.
The correct valves will usually be recommended by the vehicle manufacturer. Regardless of what pressure you run them at they must meet the requirements for the maximum given load and in most cases camper applications need high pressure type valves. I have attached a image highlighting the valves and the applications they are usually required.
If the tyres rims are not in a good condition, either rust or oxidisation then in some cases this can allow air to escape faster, due to the bead of the tyre not fully sealing on the rim. Powder coating can improve the seal between the tyre and rim but naturally air does escape over time.
There is no legal UK law stating you must remove a tyre due to its age however, we recommend any tyre older than ten years be removed from service not just due to the UV exposure but the natural ageing process which occurs. You may also find that insurance companies and coach builders recommend removal at the 5 year mark due to the application of motorhomes, which often have high uneven loads and are static for prolonged periods. This can exacerbate the ageing process in some cases.
