Im lookin for some tires that have a harder middle and softer edges, diablo's, m1's, theres so many, so help me out here plz lol.
Do i want to stay same size? or go bigger or what?
Size is the easy question: STAY STOCK.
There is absolutely no reason to go bigger. The 180s will turn quicker and feel better doing it.
The "Which Tire" question is a little more difficult...
The general rules are: The sportier/stickier the rubber, the faster it will wear out. Race tires *do* provide more grip, but only when hot and they lose their heat faster than a road tire. The more road~biased the tire, the better it will handle commuting and crap weather. The more aggressive the tire, the quicker-turning it's profile tends to be.
Let's look at some choices:
Sport-Touring tires (commuting, medium~quick road)
Michelin Pilot Road
Metzeler MEz 3&4
Metzeler Roadtec Z6 (new...)
Pirelli Dragon GTS
Sport Tires (medium/fast road use...):
Bridgestone BT-012 and 010
Metzeler Sportec M1
Michelin Pilot Sport
SuperSport tires (Fast Road/trackday)
Dunlop D207 and D208 RR
Metzeler Rennsport Street
Pirelli Diablo Corsa
HyperSport - (Trackday usage only, really. Most have "Soft" and "Hard" compounds...)
Metzeler Rennsport Race
Michelin Pilot Race (H2)
Pirelli Dragon Supercorsa
What are your riding habits??? If you commute and/or ride mixed, standouts include the Pilot Road and BT-020. I can attest that you can ride a set of BT-020s hard enough to scrape your pegs. Figure 8~10K miles from a set of this type. Mileage falls off from there kinda quickly.
I got around 5K miles a set from BT-010s, and the M1 Sportecs I have now look like they'll last mid 3K~4K. The Diablos are supposed to be a slightly stiffer constriction than the M1s, so they should last a little longer (in theory...).
Going more aggressive yet, SuperSport tires seem to average around 2~3K/set.
The key is that you are honest with yourself about your abilities and riding style. Even Sport-Touring tires are capable of going stupidly fast on the street, especially if you're a smooth and accurate rider. And yet more than a few kids still manage to crash on track rubber and then (of course...) continue to buy the stickiest things they can find 'cause they "Outride Their Tires" all the time...
