Thanks for all of the advice. I'm of the midset that I would rather not replace the tyres more than necessary just to save some cash. I know it is driver dependent and use dependent, but what sort of mileage are people getting out of various sets of tyres? My wife will be the main driver of the car and will do town driving mostly.

Thanks Alex

Goodyear Wranglers on 19" circa 25k miles

Pirelli Scorpions on 19" circa 25k

Vredestein Wintracks on 19" 25k to 30k plus

Pirellis Scorpions on 20" - front set 11k miles and rear set 15k

General Grabber 275 45 20 - virtually no wear at all over 10k miles !

Don't ask why the difference between Scorpions on 19" and 20" - I can only put it down to the sheer Torque from the 4.4 V8 Diesel which takes off like a stabbed rat and seems to eat the softer rubber tyres where there is less give in the side wall with 20"
