do larger tyres last longer??

[gti265]

i was just intrested to no if this is true or not, i can see it could be as a larger tyre would have a larger rolling radius so each part of the tyre should spend less time in contact with the road?

just wanted to no your thoughts on this

If you are replacing 17" wheels with 18" wheels then the tyre will need to have a lower profile, as you need to maintain the rolling radius to keep the speedo figure correct.  So if you are inching up correctly the rolling radius should not be affected as you stated.  Hope that makes sense.

Rich is correct.  However, if you fit wider tyres, everything else being equal, they will last longer.

Shaun, is this down to the forces (acceleration, braking and turning) which would remain constant being transferred through a larger contact area and therefore reducing the specific force per cm squared? and therefore reducing the rate of tire degradation?

Basically, yes.

Cheers that was based on my logic which is sometimes flawed!!!!
