Don't forget the effect that 35" tyres will have on your gearing, on standard gearing then a 33" is about as big as you want to go, other wise problems will arise like when pulling away on the road in high box and engine breaking down steep hills off road.
If you want 35" tyres for recreation then there are people selling part worn simexs when they have lost there edge for compatition, but still have many miles pay and play left in them.
Depending on the terrain you drive on most then the KL71 may be a better suited tread than the ITST.
Try phoning paddocks, they may be able to tell you what offset they are, though I have given up asking shops information like that which is not displayed on their website :roll:
