I used to not give a shit about tyres - just saw them as round bits of black rubber you need to have to be legal. Didn't care if I had 4 different makes, and on the last car didn't give a toss they were different sizes
But after actually looking into tyres, I'd now much rather have 4 matching tyres (model and brand) with the same wear on them. And whereas before I'd buy the bare cheapest tyres I could so as to have more money left over to buy daft exhausts or dump valves, I'd rather spend that money on decent tyres instead now.
Just saying....
