UniRoyal RS2's are £59 each (£63 delivered) at CamSkill... but then you're still looking at £10 a corner at least to have them fitted. Pretty sure 205s are actually cheaper in W over V rating too and over 195s as well, so look about and see what's best for you.
Bearing in mind they're the only thing between you and the tarmac (and a crash will cost you a lot more than £200!) and you're not exactly driving a 600cc Matiz .. I'd have a look a little deeper in to my wallet if I were you
Having driven a few things with budgets, including a couple of 182s, I'd highly recommend not buying sh*t tyres, especially at this time of the year. It's a false economy. Nothing to do with driving like a hero either (sorry Adam
) but I lost the back end of the OH's old 182 (amazeballz Infinity tyres on the back end, y0) at 20mph on a roundabout at 7am on the way to work.
We've just replaced the fronts (mismatched sh*tters) with a pair of UR RS2's on her current car and it's honestly made an enormous difference.
