Most dangerous things: tyre discussions, damper discussions, oil discussions. Each of them can destroy best friendships.
@Dougal Cawley , thank you so much for letting us know about the CN36 195/70x14. Good news for a lot of people. You also sent a note to the E3 Club, good idea, hardly anyone in the E3 Club uses this forum. Quite a few members, mostly Germans, use 205/70x14, usually XWX. Some others would not use anything else than the CN36. If these are willing to reduce tyre width they will be very happy now.
I cannot say whether BMW ever fitted the E3 with the CN36 or not. Michelin 195/70x14, then X, then XWX, were available as factory option roughly from September 1971 until September 1973. During that time, you could also order 195/70x14 radial tyres, HR or VR, without specified manufacturer. In September 1973 the Michelin option was dropped. As I understand it, the XWX option was never available for the 3.0 Si, maybe because the 3.0 Si intially ran on tyres with belts.
One funny thing we noticed some time ago 205 tyres lift the car up more than expected compared to 195. We had two otherwise identical E9 at the shop, both XWX on 7" radial spoke, one with fresh 205, one with old but hardly used 195. The difference in height was surprisingly large.
On a personal note, my E3 runs on Dunlop SP Sport Classic 195/70x14 for nearly 30'000 kms now, motorways, country roads, British country roads, heavy rain and so on. Please don't tell me the Dunlop are disastrous because I really love them.
Cheers Christoph
My contacting the club about these tyres and banging on on forums and facebook is viewed in different ways. Some people think it is dreadful advertising and shouldn't be allowed. However, all though i wouldn't argue that it isn't advertising, i hope it is predominantly informative. When it boils down to it, i think you guys want to know there is a new tyre choice. When a tyre comes out this social media is an accurate way of informing people that are interested that there is now a new tyre.
I often come accross problems when a new tyre comes out, in that maybe a few years ago a lot of research was done by people into what is the best tyre from the options available at the time. They spread the word and then people can get stuck in their ways. A decision was made. However what makes the best tyre available is relative to what tyres are available at the time, and when another tyre becomes available, what is best can change. With this CN36 what we have is a tyre of the correct size made with the correct kind of carcass, by one of the worlds best tyre manufacturers. The CN36 has to be a stong contender.
A difficulty i have when it comes to discussing tyres is that i do occasionally come accross arguments from people that are difficult and they can be scientifically and mathematically proven wrong. yet refuse to accept it:-
- "i took off the 14" wheels and fitted a tyre that had the same diameter on 16" wheels and the ride was better" - no it wasn't. if the tyre side wall is not as tall, the ride is not as good. (if the side wall is rounded like a period tyre that makes the ride even better)
- "i took off the 195 section tyres and fitted 225 section and the steering was no heavier" - that just isn't possible. I am not a big enough nerd to know if an E3 has power steering or not. if it does the extra load may be hidden from you, but the load is on your steering components. In those it was pretty extrordinary for a car to have a front tyre bigger than 205. The countach was on 205 section front tyres untill 1985. (a more modern tyre carcass presents more foot print to the road in relation to the section width than a classic tyre, which enhances the derogatory effects)
this is quite funny
this is from the 1996 Michelin collection brochure. amusingly at the time they had 2 options of 195/70R14 XWX and XDX both listing a diameter of 647mm. which i think is silly because if you do the Math it should be quite a bit shorter than that. and more importantly the 200 book in a bit contradicts it. However at the time they only list the 205/70VR14 in the XDX. well i dont think that would make Ferrari Dino owners very happy.
Right this one makes a bit more sense
this is the 2000 book
so the 195/70R14 is listed as 630mm and the 205/70R14 says 644mm diameter which is more like it.
(70% of 205mm X 2 =) 287mm + (14" X 25.4 =) 356mm = 643mm
Incidentally the current range of Michelin list the diameter of the current 205/70R14 XWX as 644mm
I'm going to appologise for this next coment before i make it, but when you changed from an old tyre to a new one and were suprised by how much it raised the car - did you check the tyre pressures before you took the old ones off? that could make quite a difference. - did apologise i hope i am not teaching grandma to suck eggs and if i do i do it humbly
next point is; if you have the same tyre pressure in a bigger tyre it will sag less in the side wall, if that makes sense. I am going to make some statistics up now; maybe if you had 30psi in a 195/70 section tyre it might sag by 10% where 30psi in a 205/70 tyre might sag by 9%. don't quote those statistics, they are totally made up as an example to explain a point which i again humbly apologies for trying to sound like a smartarse.
Oo - now i am treading on dodgy ground - the new Dunlop Sport Classic.
Why didn't they make it look good? All that history Dunlop have and they just make up a new tread pattern, and give it a ridiculous modern side wall design. And then, this si the really daft bit; why do they have the word 'Classic' written on the side. That is a real school boy error.
I think they are a pretty good tyre. i don't think they are as good as the Pirelli. i don't think they are as good as the Michelin in a hot country. I think they look silly. i have the same veiw of the Vredestein. I think they had a place when they were a bargain. I think the Pirelli is a better tyre. I think it is actually a genuine period tyre and it looks good. The CN36 has the quality, the history and the looks. (as does the XWX in my mind).
If you are going 16" how a bout the P7?

thats what the M1 fitted. It is actually a more low profile tyre that is in some way designed to go with this kind of geoemtry (but i would just put it back on 14". you aren't racing.)
