What modifications if any would be required to run this size wheel and tyre package?
Is a lift kit required?
What about wheel spacers?
What size wheels and tyres do you think these are?
Many thanks.
It depends... what do you want to do with such a vehicle? If it pose and nothing more arduous than a Tesco carpark then a lot less than if you want to off road it.
I'm not against big wheels, but be aware they'll blunt performance, esp on something like a Tdi, reduce braking efficiency, induce more bump steer, probably reduce mpg and knacker the turning circle.
Lifts are not really a good way for fitting bigger wheels normally. As under full suspension compression you'll loose the lift and they'll rub. You can limit suspension travel, but that is usually pointless if you care about off road performance.
At a guess they are 16x10 rims with an ET00 offset. Wheels cannot legally stick out of the arches in the UK (Construction & Use Regs, not MoT). The big arches may require the wings cutting, depends on the exact arch. While the front wings can be replaced, the rear are part of the body tub, so not really a reversible mod.
Big tyres will also fling a lot of dirt up the sides and over the door handles.
