I agree with john definitely not a waste of money chris my e36 was horrendous a few year back so I bought a set of 16's for it and put 4 winter tyres on it the car was great in deep snow with them on the e36 is very light over the rear and it just got stuck on the smallest inclines especially at traffic lights it was a nightmare

I had a set of winters is well in 15" for the e39 but when I changed to bigger brakes they wouldn't clear the calipers so at the moment iv only the one set of wheels must pick up a second set
