geez the tire stuff seems confusing. No wonder the dealers can charge so much.
Motorcycle superstore has these Metzeler-Lasertec Bias Sport Touring Front Tire 110/80H-18 for $97.99
and these Metzeler-ME 880 Marathon Touring Rear Tire 170/80/HB15 for 140.99 including shipping.

Are these the right sizes and compatible and is the price reasonable? I think I prefer the lasertec tread pattern for the front at least.

somewhere i saw something about a triumph-specific lasertec but i've lost it now.
