Thoughts on.....increasing tyre widths (987 gen 1)?

Hi all
Quick one....I was mooching over some US forums re spacers (some comments made re re increased wear and tear on the metalwork around the wheels) , and read about others moving their tyre size up (e.g. from 265 to 275 at the rear, corresponding increase at the front, no change in profile) with no adverse effects and supposedly a small increase in road holding through corners etc.

I can see the theory re a slightly fatter "road footprint", any thoughts from the informed masses? I've applied this in the past to my daily commuter (Volvo Estate...before you throw rotten fruit at me, it is a Sport version and has been remapped :)! ), with positive effects.
Cheers

Hi Craig,

Is this for road use or for track days?

On public roads I would not think you would be driving at the speeds where any difference would be noticeable. On the track there might be a small difference, but better/lower suspension would have a bigger effect. Not forgetting, of course, that the biggest factor in improving lap times is driver coaching.

Regards,

Alan

 
Craig,

I'm with Alan on this. Plus, in the handling stakes a Volvo estate is a different kettle of fish compared with your Cayman..!

Not much to be gained by changing tyres by 10mm width but also unlikely to be detrimental, if you check the detail measurements of different tyre models and brands you will most likely find that some have a wider tread width than others for a given tyre size. If you went to a brand with wider tread and happened to go up a width then there could be the possibility of clashing with metalwork when you hit a bump
