What tyres does the 635csi use?

Hi there,

I'm thinking of changing my Volvo 480 Turbo for a 635csi. I read up about the tyres being metric

What tyres and how much am I looking at for these? Can the alloys be changed to take diff tyres?

What else should I look for on the 635CSI? I hear front wings rust rather well.

Many thanks

Martin

Welcome Martin!

You wouldn't be the same Martin Holmes who organised the Birmingham Superprix in the 1980's by any chance? Probably not, but I just wondered!

All 635's would have been supplied originally on metric diameter wheels, which obviously neccesitates the fitting of metric rubber. Nowadays its horrifically expensive, so most owners change to imperial sizes, either 15, 16, 17, 18" rubber.
The different diameters provide differing levels of comfort, grip etc.

My two 635's run either 235/45/17 all round, or 235/45/17 front, with 255/40/17 rears.

If you have a good flick through this part of the forum index, you'll find plenty of info, differing opinions etc.

Also, on bigcoupe.com itself you'll find great buying advice etc.

Once again, welcome!

Dave :)

|Hi Dave,

Thanks for the quick reply

Does the engine come any smaller or just 3.5lt?

I'm not the same Martin, infact I was only 9 when the 80's came to a close.

I like 480 turbo (bigger turbo / larger injectors / very special ECU) but it's already eaten one autobox

so it has to go.

Cheers

Martin

Well, there is the 2796cc unit (628CSi), and going even further back in time, the 3210cc engine (633CSi).

Note that the 3.5-litre comes in three variations:

3453cc, 12-valve, up to April 1982

3430cc, 12-valve, from May 1982

3453cc, 24-valve - M635CSi only (UK-spec RHD from 1985)

I thought the 628 had a 2788cc engine, he said pedantically....

cheers
