Tyres for BX auto

Post by charlotte001 »

On my 1989 BX 19 auto I have 185/65/14's on handling seems to be ok. By how I understand it the aspect changes on tyre size ie 185/65/14 would be 195/60/15 or 205/55/16 etc I know some tyres on an odd occasion changes aspect on size.

Main difference may be a slight alter of the speedo you may be going faster than you think or slower. Pop down to fast fit they'll put you right

They're not quite right for a BX. The correct size is 185/60/14, which means your speedo will be reading a little slow.

Slight edit for real-worldness.


155/80 14's I believe were the standard fitment for non-PAS cars, as the smaller width tyres keeps the steering light. Usually these are on 1.4 models. You can change to 165/70/14's without concern. Your steering might get very slightly heavier at very slow speeds, but on the move there will be no difference.

Why is this?
Could i simply change tyre sizes to 165/70 (or even 175/70s) which seem to have the same circumference?
The 16 autos were specified with a narrower tyre for tax reasons in France apparently. You should fit 165/70 14's IMHO. 175s will fit OK but handling will be affected a little bit as the tyre will flex more on cornering.

Sorry double post. There is something else too - economy will be very slightly better (as will handling in snow) if you chose the (cheaper and more readily available) 165's!

Thats a bit pricey unless it includes fitting & balancing? Either way you've made a good choice on tyre make, very good & a damn site cheaper than the usual brands which i dont think are as good, cant go wrong really.

Which model are they, Hi-Trac?

Thats a pretty fair price considering its an all in cost as you've described. Unknown brands can be really dodgy & most are probably re-treads, not what i would call safe, trackday fodder only :lol:

Legally, any tyre which is a re-tread must be marked as such. Not that re-treads are as much of a problem or danger as they used to be. After all, most rally cars hammer around on re-tread tyres.

In fact, I can't remember the last time I even saw re-treaded tyres on sale. New radials are so inexpensive these days that I can't imagine there's a market for re-treads any more.

Tyre anorak to the rescue!

I *think* there's a couple of remoulding companies left, Kingpin were going about 6 years back and Colway seemed quite popular. Half the battle was convincing people remoulds were any good after some of the scare stories about them, and indeed I went to fit a new 'Motorway' remould for someone once that had a nail in it I kid you not.
Anyhow, half the problem now would likely be that cheap crap imported tyres aren't really suitable or wanted for remoulding, it's premium brands like Michelin that are best suited. that leads to the little problem of disposing of old cheapo make tyres and I suspect incineration, shredding and export are the three big avenues seeing as you can't landfill them anymore.
Vauxhall apologist.

Tyres get recycled these days & turned into aggregate for road building etc... quite clever really...
