I got a discount on my tires by buying a whole seasons worth for my SV at the beginning of the season. I contacted my local Dunlop tire rep and ordered 8 sets of tires for my season. I was a bit off, and will need one or two more sets, but at least I will use the full 8 sets of tires. It was a big nut to buy 8 sets of tires up front, but the discount was worth it.
Read between the words and your answer will be there young grasshopper. "The best deal on tires is not always the best deal". Dunlop rules!!!
