The key question is what wheel size do you run? Not all makes support all sizes- so knowing what you have now will help others offer advice.
My last Treg came with Pirelli P Zeros on 19 inch rimes- I only got 9,600 miles out of these as they are very soft (they are a high performance tyre, speed-rated for the Tregs sister- the Porshe Cayenne).
I swapped to General Grabber UHPs and was impressed with thier wear, reduced noise and the price.
My current Treg was new 6 months ago and again came with Pirelli P Zeros (this time on 20 inch rims) and they have done 3,800 miles and have gone from 8mm tread at new to 5mm now. When due for new tyres I will go for Grabber UHPs or similar- anything but the Pirellis (they cost over ?1,100 for 4 :shock: )
