Whatever you do, make sure you ask for 2 front tyres. What the idiots in places like Evans don't realise, is that all the big tyre manufacturers sell rear tyres for the same price, and yet they use cheaper rubber, and often recycled metal or kevlar beads from old front tyres that customers have traded in at their local bike shops, which the retailer then returns to the manufacturer for a small rebate.
2 front tyres will have substantially less rolling resistance, and be more punctureproof, than a front and a rear.
this took me four whole years and countless pounds to realise, front tyres last 10x as long as rears
