Spare tyre holder and grooving

We had new tyres fitted to our van about 2 months ago, and the spare although unused was past it's sell by date, that said it was in pristine condition visually with even the tread "hairs" still intact. But where the tyre carrier touches the tyre there were grooves in the sidewall, which in my opinion would lead to weakness. So what do you use to stop this? Or do you not know it's happening, could be worth dropping the spare wheel carrier and having a look while your at it why not fit an extender to your valve, check Ebay, I got mine for about £6 a year or so ago, saves dropping the wheel to check the tyre pressure, which means your more likely to do it

An interesting statement Agger.
Two years ago I decided that we might as well carry the Eriba spare in the car but when I removed the under slung tyre rack, I noticed that the "NEW" spare, A Dunlop SP, complete with hairs, was in fact the same age as the van . It was unused but showed a slight depression in the side wall where the rack had been squeezing it.
I immediately took it to our local tyre specialist who thoroughly checked it out and although I made him aware of the age and the depression, he assured me that the tyre was in perfect condition and should cause no problems.
Before our journey this year, I took the tyre in again and he confirmed what he had told me the previous year.
When it comes to tyres I am very cautious but took his word for it. After a thorough inspection of the road wheels and tyres which were by now a little over 4 years old, we set out. I normally check the tyre pressures and give them a quick examination before leaving every camp site.
However, when we reached Barcelona and as I was reversing the van onto the pitch, I noticed severe and rapid tyre wear on the outer edge of the door side tyre. This showed up because we were on sandy ground and the sand was highlighting the depth of the tread.
I was faced with having to use the Dunlop spare but before changing the wheel I examined the wheel drum and suspension for movement. There was none.
That "new" old Dunlop has brought us all the way home and is still looking in perfect condition so whatever it was that caused the rapid tyre wear to the newer tyre remains a mystery.
I don't wish to condone the use of old tyres but it does show that some remain in perfectly good condition, especially if they've been carried as a spare, out of the elements and never used.

I tend to agree but like you err on the side of caution, the grooves are imho caused by the weight of the tyre and rim pressing down and being partly compressed by the tight fit of ghe frame. For me it is exposure to daylight and sun that is the main cause of degradation. I do feel though that the grooves should be avoided so how do we achieve it?

At service time on our last Eriba, AL said I needed 3 new tyres. Obviously I queried the third one which, they said, was grooved by the carrier and therefore should be scrapped. I went along with this but I then put some hard plastic chopping board pieces between the tyre and the frame to prevent this grooving on the replacement tyre.

Thats what I was thinking some thin but strong plastic, I had thought of a formica type materiel or an old plastic road sign (I have a friend who could get me one). Opinions differ on the groove's ability to affect the safety side but I think we all agree with a solution
