And also, having geometry set up accurately requires balljoints, wishbone bushes or radius arm bushes etc to be in A1 (ideally new) condition. I need to set mine up properly but can't do much more than camber and toe until I've swapped out the radius arm bushes, and even then I'll have to do the lot again
Once thats done I'll get the tyre levers out and fit the new set of tyres I've got in the lockup.
Its worth looking along the line of your wheels from the rear and seeing if either front wheel looks like its sitting out at the bottom (camber) compared to the rear wheel. It could be you have issues with wishbone bushes (accute wear) or one of the front wheels camber is way off (worked its way loose or badly adjusted). On the T25 the front wheels are very close to absolute vertical when correct. If one isn't, that would cause it to pull to one side, regardless of toe. You'll also get wear on the inside of the tyre on that particular wheel eventually, so check carefully for signs of tyre wear as that may help pinpoint the prob. If you're having to rest your hand on one side of the wheel all the time (likely if it pulls), you can be certain that one tyre at least is wearing abnormally.
You can get the camber pretty close to correct if you're parked on very level ground (check it IS level). A rough and ready way would be to lay a spirit level on a length of wood on the ground across your vehicle. Then if its close enough (you can even slide layers of plywood or vinyl floor tiles under one of the wheels to get the vehicle level), jack up offending corner and slacken the allen bolt and nut that goes through wishbone bushes at the top and turn the allen key (its a big one by the way) until you get the wheel upright again. You can use a spirit level in a vertical plane, resting the ends on the wheels rim. You may have to keep making adjustments until you get it right, tightening up nut again (55lbs) and then lowering vehicle, rolling forward and backward a few times and readjusting as required. Ideally it wants setting up with the same weight you'd normally have in front seats. If you aim for dead vertical on camber you'll be virtually spot on. By all means have it checked afterwards but you can do an excellent job at home if everything is level.
I measured across my wheel rims and came across a spirit level that was exactly the right size. if not you can cut a piece of wood to span the distance (making a cut out for centre cap if need be) then placing your spirit level against that. It does sound like a camber problem to be honest, particularly if the toe is right and unless you really look for it, you may not even see it.
Camber:
Just goes to show if you look after the ol' girl she'll look after you! 
however will look to get a bit more pressure in the fronts.
