i'm about to get some 15x7 bbs rims and i don't know what size or tire i should run on these. i need something that is high performance and all season.

 

"High performance" and "all season" really shouldn't be used to describe the same set of tires.

You are going to sacrifice one for the other. Best bet is some good all season tires. You have lots to choose from in a 15 inch size.

If you want high performance, then I would recommend buying a dedicated set of winter tires and a set of high performance summer tires that can evacuate water well when it is raining.

 

try the bridgestone RE750.

Great tires IMO. Turbo95max recommended these to me. They are Great in dry and wet condition.

 

i'm still deciding if i should just put summer tires on these. What's a good size to run?

 

While I agree with Cliff's statement below, summer/winter setup in Philly is a PITA to me. It gets below 40 enough weeks of the year to make a winter setup seem like a good idea, but jumps back up over 50 enough times during winter months to make winter tires a pain when you want to enjoy the weather with a little bit of lead foot. I'd guess that the entire Mid-Atlantic is like that.

I decided to go with tires that tirerack categorizes as "Ultra-High Performance All-Season". For the most part, great in the dry and wet, and passable in the snow. For the 5 days (at most) that there's real snow on the ground, I'll drive like a wimp. Otherwise, I''ve never pushed the car hard enough to need (or tell, for that matter) the difference between all-season and summer tires.

After getting stuck once (see below) I had actually bought a 2nd set of wheels to go with a summer/winter setup, but after the last 2-3 winters here on UHPAS tires, I found it hard to justify the expense, storage space, and changing hassle of the additional set.

My experiences with Dunlop SP Sport 5000, Continental ContiExtremeContact and Kumho Ecsta ASX in 225/55 16 have been great in dry/wet. The difference over our OEM tires, let alone other cars OEM tires short of sports cars can't be properly described, IMHO. To be fair, I've gotten stuck in the snow once with the Dunlops in the valley between 2 hills. Otherwise the tires mentioned have gotten me home every time with only a few scary instants, and no accidents. In full disclosure, I even bought a set of chains, just in case. I used them twice on the Dunlops (the oldest set of tires mentioned) after getting stuck, but haven't used them since.

Having looked into tires last week for 17x7 wheels, the verdict from the surveys and sales rep at tirerack was Pirelli PZero Nero M&S, but Kumho Ecsta ASX, Avon Tech M550 A/S and the Continental were right behind, with lower prices. I prefer the Continental beause there's so much more feedback reported on them compared to the other less expensive tires.

215/60 15 was original SE width, but 225/60 15 is about as wide as I'd think you'd want to go. Of course, wider tires mean more pain in the snow. The Continental recommendation is based on the fact that it's the only tire of those mentioned made in that size.

As always, your mileage may vary
good luck
