My 411 was fitted with 205/75R15 on the 6" steel rims when I bought it. I acquired the Avon wheels secondhand from Bristol and they came wearing the 215/70R15 Turbospeeds

When our cars were new, standard tyres were 205R15 tyres (82% profile), on the 6" steel rims. Not sure what tires Bristol used if the customer "optioned up" to the Avon wheels?

The aspect ratio of the 215/70R15 is approximately 10% less than the original tires, so your speedo would read a bit more than the speed you are actually doing.

Avon appear to still make the 215/70R15 Turbospeed (CR28), maybe you could import some from the US or UK.

Interestingly the Avon Turbosteel CR28 is exempt from the EU tyre labelling regulation, because the tyre is designed to be fitted only to vehicles registered for the first time before 1 October 1990.

215/75R15 may be better if you can get them.

Thanks Kevin, Greg and Peasantlife

Surprising what your learn when you get around to it. Prompted by your idea of importing the Turbospeeds I went to the Avon site (yes, I should have done that much earlier) and have found a NZ stockist. While he doesn't have the Turbospeeds listed on his own website I am asking him the question.

That would be ideal as I still have the two older Turbospeeds in the garage, never used, and possibly good as back up tyres.

Thanks again for all your help. Fingers crossed it is solved.

Peter, before you commit to buy Avons through their NZ "agent" I would contact some of the Avon retailers in the US (or in the UK) and see how much they are to buy there because there is some evidence that us colonial dwellers often pay through the nose for products which cost a lot less in the UK or USA.

Just an example, I recently bought a diagnostic tool for my Landrover Discovery 3 from a UK Britpart agent, couriered to my door for $450. The local Australian Britpart agent quoted me $770, and they had to order it from the UK anyway.

I could tell you some stories about Mercedes parts pricing in Australia which beggar belief!

Just one other thing - a 215/75R15 could be an even better fit than a 215/70R15(closer to the original fitted tire height). I discovered this is a common tire size because a lot of smaller SUV/4WD vehicles use them. The challenge of course is to find one that has a reasonable looking tread as many of them are quite chunky.

Ah, interesting you mention Tire Height - implication - you have a tendency or at least understand US nomenclature. In europe we talk of Rolling Radius which is of course a function of inflation pressures and load...
Just in case it helps Avon -of Melksham- was certainly where Turbospeeds and Turbosteels were made in the 60-80's. But the company was bought by Cooper Tires (a US firm ) many years ago and I really have no idea where they come from now, but may be a route to Avon supply even if not proclaimed, if that is your chosen path.

I have had a response from Avon Uk, referring me to vintagetyres.com, which may be of interest as their website specifically includes Bristols.

Not true ! the other tyre specialist that stocks Avon tyres are Longstone Tyres Bristol 411 Both are expensive ! I would prefer to find a close modern tyre size.
