Where to buy tyres in Glasgow area

Hi guys

The rear tyre on my bike is almost down to the canvas so I think it's time for a replacement! Currently running D207s so I'm thinking that it would be best to get another D207 for the rear so I can keep the front (still has a good few thousand left in it). Or would it be best to just get both changed? I'd rather not cos obviously that would be more expensive but open to advice.

What kind of price am I looking at? I've seen some decent deals online but cost of getting it fitted may outweigh the benefits. I usually go down this route when buying car tyres but they are far cheaper online and I can get them fitted for around £5/corner at my local independant tyre place.

Cheers
Paul.
