Re: Tyre profile on 159 Ti
I agree in principle with what supercute said earlier, namely "I never ever thought of saving money buying cheaper tires, always got the best"... But only if by cheaper we should infer inferior. The original point of this post was not to question of whether you can run inferior tyres per se, but whether the supplied tyres on the Ti are over-spec'd for the actual load of the car. Maybe I am too cynical but I could be tempted to believe that this tyre spec was NOT chosen because that's what the vehicle required. I am more tempted to believe that Alfa wanted to achieve a certain style with the Ti so they plumped for a 19" wheel to give that "oversize" look. Having decided that I guess they were faced with needing a wider tread to safely fit the 8j rim without trashing CO2 figures - hence 235s were the natural choice. Next comes the profile: 35, 40 or 45? Well 45's are out as the wheel is then too big for either the speedo to be legal or the wheel arch clearances. And when looking last at the load factor, all tyre choices were more than adequate. But what was the final decision for the 40's based upon, I wonder? Was it purely aesthetics/proportions, or is there some other "X-factor" hidden in there that would mean any discussion of an alternative is senseless?
Now of course this post would also be academic if the cost of the 235/40R19 was the same as any alternative, but it really isn't.. And that's because there are just 4 manufacturers producing this low-volume tyre - and hence the price. Now I don't want to save an extra £50-80 per tyre if I then become either illegal or driving perilously close to the edge of a ugly accident. But with one fresh set of tyres per year (at least), I'm burning £200-£320 more than I might need if another perfectly well-spec'd tyre could do the job.
So has anyone got any thoughts on the choice of the 40 profile - or do you think it was just proportions?
