Tyre profiles

I'm trying to work out if I have the original profile tyres on my car and what will fit under the current guards.

My present tyres are 195/45R15 front tyres with 225/40R16 rears.

The rears are my major concern as newer cars have 225/45R16 tyres. Ben has the later tyres but had to raise his rear guards to fit them. His guards are Atom 2 style, mounted off the uprights, where mine are not.

I've also asked the factory . Tom seems to think the Atom 1 should have been shod with 225/45R16 on the rear but can not be 100% sure.

I'd really like to make sure I get it right as I have to pay in advance (non refundable) to get some tyres bought into NZ and would prefer to get the correct ones.

So do any of you very early Atom 1 owners recall what tyres were on your cars?

To add more to this I also went from 15 to 16" wheels when I had to raise the guards so quite a big change.

Oops  :-[  missed that mod. That definitely would require some guard mods.

Even if nobody can remember the rear tyre profile of early cars, does anyone recall the brand/name of the tyres used?

I might be wrong, but I vaguely recollect my Atom 1 coming with Continental EcoContact's of some sort.  I remember Marcus at EasyTrack taking the piss out of them at a trackday, but I was still quicker than most of the other cars anyhow ;)

I have some close-up photos of the original Atom that Bruce and I shared in 2001. I'll see if I can detect anything. Have you tried emailing Tom?

I most certainly have. He replied "I honestly can’t remember".

After years of putting up with us lot you have to expect some brain cells to have been killed off.  :laugh:

It would be great if your photos reveal some information.

Just found my poster brochure for the first Atom. It kind of brings back all that early excitement.

The options were:

15" package
Front & rear: 6J x 15 Tecnomagnesio 195/50 R15

16" package
Front: 6.5J x 15 Technomagnesio 195/45 R15
Rear: 7.5J x 16 Tecnomagnesio 225/40 R16

It also mentions 14" wheels as original kit, but I doubt you need that!

Thank you Steve.  :tu:

That confirms I have the original profiles on my car and what are probably best suited to fit under the current the guards without doing major alterations to the mountings. Now I can go ahead and import some replacements.
