Well yes, Continentals are excellent tyres fitted as OEM by some of the best manufacturers, but for the price being charged there you could get a pair of 15" or 16" tyres......
Have a fiddle about here first.....and check out 16" options as well.
Or, you might consider going up a size as theres plenty of room for taller tyres which the engine copes with easily.
Your overall tyre height as it stands is same as most other models, even if they have 15" wheels. 17" is a bit of a painful size in 4x4 I think. Biggest range of tyres are made for Landy market in 15".
