Re:
There is also a 235/50 r18 that is a good match and slightly narrower. I agree with everything you have said Greg except the words 'less expensive tyres' as the cost of the tyre should be weighed against the quality in the tyre and ratings.

Re: Wheels and tyres for X-Trail
I came onto this page a while back to see if i could find some information about the X-Trails. I came across this page relating to wheel compatibility and saw an odd post.
The post stated not to really be concerned with the "rating" of the tyres on vehicles, as it wasn't all that important.
While I am a newbie here I do have an understanding on Vehicle road-worthiness/ and some vehicle specs.
Where tyres are concerned, you DO need to worry/ be concerned about that.
The X-Trail (up to 2007 i think) has 2 standard wheel/ tyre size specs.
215R7015 98H and 215R16 98H. I am not sure if there is a totally compatible 17 inch tyre available in Australia.
An explanation of the "numbers" on a tyre sidewall here is an example:
P215R6515 98H
P = Passenger - if it says LT then it is light Truck
215 = Width of the tyre in mm
R = Radial (pretty standard these days)
65 = the profile ratio this is 65% of the width - 65% of 215 - (very important for speedo accuracy)
15 = the diameter of the rim that the tyre fits
98 = the maximum load that the tyre can support in lbs - 98 will hold about 1600 lbs - if you go less it can result in a blow-out.
H = this is the Maximum Speed rating H is Maximum of 130 MPH. - if you go say S the maximum speed reduces to about 112 MPH.
Now as for the importance of these numbers -
There are more and more police personnel that understand these figures, and are able to do an on site check of the ratings for you vehicle. If they do not meet the minimum vehicle specs then you WILL be in strife.
If you are in an accident (your fault or not) your insurance, or the other persons insurance, can refuse to pay for repairs if they find your vehicle does not meet the vehicle specs.
As for rims yes they are a Ford stud pattern (i believe Mitsubishi Magna rims fit) they have a stud diameter of 114.3 mm and an offset of 40 mm the offset is VERY important. Also make sure that the ones you buy are capable of handling the weight and/ ride requirements of your vehicle - if you do a lot of off-roading, it can damage wheels that cannot handle the terrain, so keep that in mind. Not all wheels are made the same to take the same stress levels.
You "May" be able to go 17 inch wheels and tyres BUT, they MUST have a rating of 98 H minimum AND the running diameter/ circumference of the inflated tyre has to be the same as the 15 inch and/ or 16 inch standard fitments. From memory 225R5017 98H may be compatible but are VERY difficult to get. I think with 225R5517 the diameter is to high, therefore the circumference will be wrong and your speedo will be out.
Bear in mind that the lower the profile the rougher the ride. Going 18 inch is probably a little "too" far.
A good - reputable tyre/ wheel supplier will NOT fit illegal wheels and tyres - wheels and tyres that do not meet the specifications of your vehicle. You may find a supplier/ fitter that will, BUT, they are only in it for the $$$ they don't give a rats about you or the law or insurance.
Don't trade "looks" for legal/ safety...
