Cheers for all replies

I'm thinking I'll go for some sort of AT & if I really get into this offroading stuff I'll then look at another set of wheels

But another point is what size fits nicely?

Someone (maybe D Hell) mentioned 205/75 r15.
Is that as big as you can go before something starts rubbing?
I've got a 14' ( :shock: )

In AT you can probably go 225/75 R15 and be fine.

nor indeed "new" tyres, retreaded tryes pass the same test standards as new tyres, and meet the same "ce" mark

Retreads are used routinely on aircraft, commercial and public service vehicles. The financial and environemnetal costs of buying new, when an existing carcass has not been damaged or exceeded its fatigue life , UV life etc makes the case quite compelling.
If there was a serious concern they certainly wouldn't be allowed to on all 3 of these categories. Whilst the tyre that blew and flew apart on the Air France Concorde was a retread, and BA didn't use them on their Concordes, there equally is no evidence that a brand new tyre wouldn't have behaved the same when striking that debris at that speed. If you've seen what happens to an aircraft tyre upon landing and braking, and that they're often inflated to 150-300 psi, then it's fair to assume that as with everything, if the retreading technology is used, controlled and inspected properly, they are as safe as a new tyre. Car remoulds did have a bad rep in the 60's, but the rogues seem to have been dealt with years ago...

See Jake's tyres for evidence to the contrary....

im not convinced Clive. If T25s had the aerodynamics of a plane and were designed to spend most of their operating time (syncrosam like) in the air, Id be more inclined to accept the reassurance.

As aircraft are never relying on just one wheel in each corner Id expect that aircraft designers have factored out most of the failures that can occur. How many miles on the ground can an aircraft clock up before the tyres are changed and how often are they inspected by the ground crews?

While Im not blind to the commercial interests of tyre manufacturers, their research has shown that there are an awful lot of people out there running on tyres that are mostly under pressured and/or damaged and/or below the legal tread limit and are blissfully unaware of it until MOT time.

If you add into that mix the uncertainties associated with retreads you have in them the potential for a far greater problem from failures than we see today.

The quality of manufacturing and a CE mark take no account of the treatment and maintenance a retread is going to receive from the user once fitted.

Perhaps it is this more than any other factor that prevents motoring associations coming out in favour of retreads.

I could be up for some colway MT 15/215/75s if it makes a difference to price too. (not before next year though).

I'm confused, why would the above be any different if you were running 'new' tyres? Do 'new' ones float gently above the ground and avoid wear / damage? I could save a fortune in 20p's if they never need inflating either :shock: [/code]

Im suggesting that poor tyre maintenance may bring about a higher number of blowouts, flats, delaminations on retreads than on 'new' tyres is all.

I have no real issue with retreaded tyres by the way, for off road use they are a sensible choice on all counts, my slight concern is with extensive road use.

I was wondering,
215/75-15 seems the be the popular choice, but with the taller gearing it creates, maybe a 195-15 is an option.. bigger than a std 185-14, but a bit less than the 215.. any thoughts?
I have also seen some very aggressive 185-14's... but of course if everyone is running 15/16 then the 14's will not give the ground clearance for the ruts!!!

And I know Mr Hell.. why do I need tyres when its parked.. it wont be soon.. :shock:

the main reason that 15's were chosen is the lack of available rubber for 14"

It ain't just that.

Bigger tyres, more sidewall and more width. Help spread the weight etc.

And as Matt says, in comparison to 14" there is a world of choice available in 15 - as Zuks and Mitsubishi's run them...

I've got 225/75-15's on the Westie at the moment, yes it has effected the gearing - but it will still cruise at 65.

You also get more ground clearance when fitting bigger tyres.

Yeah Matt but I have found some 14's.. the 15's offer more ground clearance so they have that advantage..

The question was more along the lines of, why 215's when a 195 was a little closer to the std size? wider footprint helps a lot too?

I doubt many would go back to 14's... would you?
